* Removed game.on_save function. There should be no need for it and it was causing too many problems.
* Lua on_load function is not called when saving the game anymore. It is called only on actual load now.
* Lua API calls '''on_load''', '''on_init''', '''on_configuration_changed''', '''on_event''' and '''generate_event_name''' have been moved to a new namespace called '''script''' (so from now use '''script.on_load'''(...)). This will break many mods! The callback registered in '''on_load''' function doesn't have access to the game API. This is to avoid common desyncs. The '''on_init''' and '''on_configuration_changed''' still retain the access to the game API.
* '''on_configuration_changed''' is fired when the map version changes, a mod version changes, a mod is added, or a mod is removed and passes "data": Pushes old_version="x.x.x", new_version="x.x.x" when loading map versions other than the current version When a mod version is changed it appears as a table of mod Changes {["Mod name"] = {old_version="x.x.x", new_version="x.x.x"}, ...} When a mod is added it appears as: ["Mod name"] = {old_version=nil, new_version="x.x.x"} When a mod is removed it appears as: ["Mod name"] = {old_version="x.x.x", new_version=nil}
* Changed LuaGameScript::makefile to LuaGameScript::'''write_file''' and added an optional third parameter bool to append.

== 0.12.0 ==

=== Features ===
* The game is now finished by launching the rocket with satellite.
* Added chain signals, they can be used to make more complicated junctions and stations without deadlocks.
* Added personal roboport as modular armor equipment. Once it is active, it uses the materials and robots in the players inventory. It supports all the tasks construction robots can do like building blueprints, repairing structures, deconstruction etc.
* Added logistic trash fields to the character GUI. They supply items into the logistic system in the same way active provider chests do.
* Added combinators (Arithmetic Combinator, Decider Combinator and Constant combinator). These allow more advanced manipulation with the circuit network logic ([https://www.factorio.com/blog/post/fff-88 more])
* The Lamp, Storage Tank, Small Pump and Offshore Pump can be connected to the circuit network.
* Multiplayer latency hiding (gives impression that some common tasks are performed immediately) Applies to character movement, mining buildings, building, fast replacing, opening guis, etc.
* Stone brick can be used to build stone path. (30% walking speed increase).
* Concrete can be created. The concrete can be used to build concrete floors (40% walking speed increase).
* Terrain modifies vehicle friction force (sand: 1.8, grass: 1.6, dirt: 1.4, stone path: 1.1, concrete: 0.8).
* Trees degenerate slowly when there high pollution levels.
* Lab research is now continuous. Science packs have progress bars of usage. This means that 20 labs doing research with 10 units will still be faster than 10 labs and the science packs aren't wasted.
* Assembling machine input slot can contain more than the usual stack size when the recipe requirement demands it (3 X recipe demand). Example: The rocket silo requires 1000 steel, while the stack size is 100, but the input stack can hold enough.
* Added / updated sounds for biters, spitters, worm, spawner, flamethrower, tank, lasers, etc.
* New ambient soundtrack added. Added mechanism that prevents playing track that was played recently. The ambient player alternates between neutral wind/environment sounds and soundtrack songs.
* Mousing over a train will show you its current path and blocks it can't enter.
* Locomotives now show the contents of attached cargo wagons in their tooltip.
* Trees regenerate health slowly.
* Added support for transferring contents/settings when fast-replacing all entity types.
* Added modules to the alt-view for entities that support modules.
* Factorio can run as a dedicated server without Graphics ([http://www.factorioforums.com/wiki/index.php?title=Multiplayer#Headless_server more]).
* Basic PvP: New forces can now be created and merged back together; a cease-fire can be agreed upon between forces
* IPv6 support for multiplayer.
* DNS names can be used when connecting to multiplayer game.
* Enabled mining trees/ghosts while holding blueprints to be built.
* Added explosive cannon shells.
* Building blueprints over existing ghosts restores the ghost time to live to full.
=== Changes ===
* Disabled loading of saves before 0.9.0 version (You can use 0.9.8 to load older saves and re-save them).
* Removed rocket defense entity.
* Items on transport belts don't go off the belt at the end, so the transport belt has to go directly in front of the required inserter.
* Reduced number of rendered Roboport connections.
* The trade in the marketplace only happens if the player can accept the trade items.
* Inserters can now extract from Roboports and Beacons.
* Inserters now take items from right behind them, not from the center of the pickup target entity.
* Copy entity settings mechanism now remembers only the last entity copied from. Also mechanism allows copy/paste across different entities of the same type (i.e. assembling machine 1 -> assembling machine 2) and from assembling machines to requester chests (sets filters to 2 x requirements of the assembling machine).
* Trees have generally smaller bounding boxes, so it is easier to walk through forest.
* Power armor modules generate and consume 100 times more power in order to be able to charge construction robots.
* The construction robots don't build gate in the gap between the rolling stock vehicles. They wait for the train to get away.
* Player's logistic filters are now remembered after respawn in multiplayer
* All turrets are now 2x2 (incorrectly stated as 4x4); laser turrets are 4x more expensive and powerful, gun turrets are 2x more expensive
* Roboport tooltip now shows correct numbers of construction and logistic robots separately.
* When a train loses a path and cannot find a new one, it stops immediately. This prevents it from riding into parts of the rail network, from where it can't find a path.
* Improvements to circuit network wire connection. You can connect multiple wires of the same color to the same entity.
* The autosave dialog no longer cancels an active blueprint or deconstruction planner selection if the mouse button is still held after the autosave finishes
* Number of autosave slots is now configurable through config.ini (no GUI).

=== Optimizations ===
* Overall optimization of train + belt heavy factories is roughly 66% compared to 0.11, this means that the game runs 3 times faster.
* Optimised the transport belt movement.
* Optimised the rotated bounding box collisions checks (trains).
* Optimised the smoke update.
* Optimised the solar panel, all the solar panel input is merged, so the count doesn't matter.
* Optimised the accumulators by merging then into groups, where typical factory has 1 group per network.
* Optimised the land mine activation mechanism.
* Smaller multiplayer heartbeat packet size.
* Optimised adding/removing of roboport, robots keep their tasks if they can.
* Path finder will terminate when search is too long. This avoids save explosions (see [https://forums.factorio.com/12580 more]).
* Optimised rendering for large logistic networks.
* Fixed that the Graphics were saved twice in the RAM memory.
=== Graphics ===
* New Graphics of the combat robots.
* New Graphics of the laser/gun turrets, their color is now player/force dependent.
* New Graphics of muzzle flash for player, car, tank and turrets.
* New tree Graphics. Trees have 4 levels of leaves and the leafs are color-able.
* Trees emit leaves (based on the tree color) when being mined and destroyed.
* Trees emit branches when mined or destroyed.
* Storage tank has a small window showing the liquid inside.
* Combat robots attack beam ([https://www.factorio.com/blog/post/fff-84 more])
* New GUI icons: Weapons, ammo, status icons such as out-of-ammo or out-of-electricity
=== Bug Fixes ===
* Fixed wrong item count in the logistic system when handling partially-filled magazines, repair packs or other items with durability
* Fixed the choppy (not smooth) movement when using the exoskeleton equipment.
* item-description localization now displays correctly when previewing recipes.
* entity-description localization now displays on entities.
* Proper blueprint centering. It is based on the included entities rather then the selection rectangle when the blueprint is created.
* Very big entities no longer disappear at the edge of the screen
* When putting things on ground, the first item was never put exactly under the cursor even when the place was empty.
* Fixed that it wasn't possible to swap stacks of the same items with different health.
* Fixed strange behavior of tank/car entering sound.
* Fixed LuaFluidBox crashing the game when attempting to read fluid from an entity that previously had fluidboxes.
* Car / Tank ammo inventory is refilled from the trunk / player inventory when exhausted.
* Fixed writing invalid LuaEntity::selected_gun_index crashing the game.
* Fixed the power armor battery level indicator getting drawn on top of everything else ([https://forums.factorio.com/8206 more]).
* Fixed that following robots created through trigger crashed the game.
* Fixed the train pathfinding issue when the train crashes to something while stopping for signal or station in front of a junction.
* Fixed that crashing to something while in manual mode in train could switch it to automatic mode.
* Fixed crashing when setting modded GUI styles in Multiplayer.
* Fixed crash when trying to read LuaPlayer::opened on a dead player.
* Fixed crash when canceling deconstruction of a logistic container that was marked for deconstruction after the logistic network it was in lost power and then regained power ([https://forums.factorio.com/10143 more]).
* Fixed LuaSurface::can_place_entity returning true when checking item-on-ground against item-on-ground ([https://forums.factorio.com/9247 more]).
* Turrets can now be modded to use shotgun (and other not guided) ammo.
* Fixed research window appearing behind the selection/minimap pane when shown from research completion ([https://forums.factorio.com/13235 more]).
* Fix inability to bind some OEM keys on Windows. Added the ability to bind more keys including multimedia keys. ([https://forums.factorio.com/10027 more])
* Fixed marking a ton of entities for deconstruction outside the construction range of roboports slowing down normal deconstruction rates.
* Fixed crash when removing electric poles from electric networks or circuit networks with large amounts of poles ([https://forums.factorio.com/13368 more]).
* Fixed video-memory-usage option on Windows. It is possible to run Factorio on configurations with low VRAM (less then 512MB). Other platforms don't have this issue.
* Fixed that control-clicking entire inventory into a machine installed modules.
* Fixed another instance of the "Trying to make chunk at unreasonable position" bug ([https://forums.factorio.com/13399 more]).
* Requester chests no longer request more than they can store. E.g. if a requester chest only has one free slot and the requester slider is set to request 20000 iron ore, the chest will only request one stack from the network ([https://forums.factorio.com/4604 more])
* Console no longer loses focus after an autosave ([https://forums.factorio.com/10025 more])
* Fixed wrong highlight when crafting ammo in vehicles ([https://forums.factorio.com/9620 more])

Holmium ore

Luc: add a gotcha for productivity, since holmium ore can be a bottleneck for most bases and then scrap productivity is important

{{Languages}}
{{:Infobox:Holmium ore}}
{{About/Space age}}
'''Holmium ore''' is a rare resource that can only be found on [[Fulgora]]. It has a 1% chance to be extracted from [[scrap recycling]], and can be found in [[fulgorite]] deposits.

The only recipe which consumes holmium ore is [[holmium solution]], which is a [[Fluid system|fluid]]. Because [[quality]] does not apply to fluids, high-quality holmium ore provides no benefits. The holmium solution recipe also requires [[stone]], so to consume holmium ore of a particular quality, stone of equal quality must also be provided.

== Scrap calculation ==
To get 1 holmium ore, 100 scrap need to be processed on average. This will result in also getting, on average:
* 1 [[Low density structure]]
* 2 [[Processing unit]]s
* 3 [[Advanced circuit]]s
* 3 [[Copper cable]]s
* 4 [[Battery|Batteries]]
* 4 [[Steel plate]]s
* 4 [[Stone]]
* 5 [[Ice]]
* 6 [[Concrete]]
* 7 [[Solid fuel]]
* 20 [[Iron gear wheel]]

Note that scrap productivity only works properly if the recycler processes (nearly) only scrap: if you have 50% productivity on scrap recycling and the recycler processes one piece of scrap, the productivity progress bar goes to 50%. If the item directly afterwards is again scrap, it will fill to 100% and you get the bonus. But, if you process something else instead, the progress is lost and starts again at 0%.

Galaxy of Fame

2025-02-23T03:27:46Z

Luc: /* Star Position */ make coordinate names match how they are afaik shown in the game and galaxy URL; add stats on how many stars are in central quadrants; and it's not impossible to find your star if you do a naïve bisection search...

{{Languages}}
[[File:Galaxy_of_fame.png|thumb|600px|right|The Galaxy of Fame as it appeared on 17 December 2024]]
{{About/Space age}}
The [https://factorio.com/galaxy Galaxy of Fame] is a feature available upon beating Factorio: Space Age. It is a database of saves that have beaten the expansion, able to be viewed on the Factorio website. It appears as a vast galaxy of stars of all size and colors. Each star belongs to one particular player who has beaten Space Age. Clicking on a star will bring up a snapshot of that player's save.

After reaching the [[solar system edge]]{{SA}} and viewing the victory screen, the player will be invited to upload a snapshot of their save to the Galaxy of Fame. Only one snapshot can be uploaded per player; uploading a new snapshot will override the previous one. The player can also include a custom name and comment. After uploading, the game will provide a link to the player's snapshot on the Factorio website.

After winning, the "Galaxy of Fame" button will appear on the main menu. Clicking it will allow the player to upload a new snapshot, or click the link to the existing snapshot.

== Snapshot ==

[[File:Kovarex_gof.png|thumb|600px|right|The Galaxy of Fame snapshot of lead developer [https://www.factorio.com/galaxy/Iron%20I:%20Alpha1-1.A1W3 kovarex].]]

The Galaxy of Fame includes the following information:
* A custom name & comment (optional)
* The date of upload
* Time played
* Game version
* Map seed
* Player count
* List of mods
** This includes both the four mandatory mods (Base, Elevated Rails, Quality, and Space Age) and any user-created mods.
* Map views of the five planets, in the order they were visited
* Map views of all [[space platform]]s{{SA}}, in the order they were created
* A full list of the number of all items produced
* A full list of the amount of energy produced by each [[power production|power source]]
* A full list of the number of kills, including all [[asteroids|asteroid]] varieties

== Star Position ==
The position, color, and size of a player's star is randomized upon upload. Given the vast number of stars in the galaxy, it can be difficult to locate your own star on the map by searching manually. However, each star's position is fixed and will always be in the same place.

Each star is placed by a set of coordinates which can be read to reliably locate it on the map. A star's coordinates can be located within the URL of the snapshot that is provided upon upload. As an example, the following is the coordinates for the snapshot of lead developer Kovarex:

Iron I: Alpha1-1.A1W3

==== Sector ====

The first word of the URL, named after an item, designates one of sixteen sectors within the galaxy, laid out on a grid pattern. The four central sectors, containing the majority of stars (28'900 out of 32'600, as of February 2025), are named Iron, Quantum, Sulfur, and Calcite, and are marked in '''bold''' in the chart below.
The sectors as they are currently known, are laid out like this.

{| class="wikitable"
|-
| Copper || Ammonia || Fluorine || Carbon
|-
| Bioflux || '''Quantum''' || '''Iron''' || Stone
|-
| Lithium || '''Sulfur''' || '''Calcite''' || Electrolyte
|-
| Uranium || Tungsten || Holmium || Yumako
|}

==== Quadrant ====

The numeral after the sector name designates one of four numbered quadrants within a sector. The table below shows the layout the quadrants within the Iron sector as an example. Each sector has its quadrants split up in the same pattern, so the quadrant to the immediate left of "Iron III" would be "Quantum IV".

{| class="wikitable"
|-
| Iron III || Iron IV
|-
| Iron I || Iron II
|}

==== Region ====

The second word, named after a letter of the Greek alphabet, designates a region within a quadrant. Each quadrant contains 9 regions. Their position within the quadrants are structured as follows:
{| class="wikitable"
|-
| Eta || Theta || Iota
|-
| Delta || Epsilon || Zeta
|-
| Alpha || Beta || Gamma
|}

The two numbers after the region name designate the star's location within the region. Each number can go between 1 and 7. The first number increases from left to right, while the second increases from bottom to top. The two of them together position the star within a region. For example, a number of 1-1 designates a position within the bottom left of its region; 1-7 in the top left, and so on.

==== Exact position ====

Following the dot, the final pair of letter-number sets designates the exact position within a region. Letters go from A to G (the first letter) and T to Z (the second), and increase from left to right. The first letter will only be advanced by one when the second letter advances through all 26 letters. For example, A1Z1 comes before B1Y1. Numbers once again go between 1 and 7 and increase from bottom to top. The same rule from letters applies to numbers.

As a final example, a coordinate of Quantum II: Gamma5-1.A7Z1 will give a position as follows:
* Quantum sector
* Bottom right of Quantum II quadrant
* Bottom middle of Gamma region

Damage

2025-01-27T15:11:10Z

Luc: /* Resistance */ Bottom line up front: first mention how it's shown in game and what that basically means, before going into details in subsections

{{Languages}}
[[File:player_attacked_by_biters_small.png|thumb|300px|right|Red flashing while taking damage.]]Taking '''damage''' is the effect of lowering the health of the [[player]], [[enemies]] or other entities.
== Overview ==
In Factorio, entities have health, can die/be destroyed, and have resistances. ''Damage'' is defined as the concept of lowering an entity's health by using an attack, such as a gun firing at it, or a biter chewing on it. An entity's resistances will define exactly how much damage the entity will take off of an arbitrary attack.

The player's maximum health is 250 (without [[energy shield]]s), and this limit can be increased through the [[Health_(research)|Health]]{{SA}} technology. Other entities' health values are listed in their individual entries.

== Achievements ==
The concept of damage is directly connected to the following achievements:
{{Achievement|run-forrest-run}}
{{Achievement|pyromaniac}}
{{Achievement|steamrolled}}
{{Achievement|golem}}
{{Achievement|watch-your-step}}

== Damage types ==

=== Piercing power ===
Piercing power is present with [[tank]] ammunition. It determines how much HP of enemies can a projectile damage before it is no longer able to travel further. To penetrate an enemy, the enemy has to be killed by the projectile, and the damage dealt for the kill must be less than current piercing power.[https://forums.factorio.com/viewtopic.php?f=5&t=30917] The damage dealt also decreases piercing power. For example, shooting medium biters with 75 health with a cannon shell of 300 piercing power means that the shell will pierce through 4 medium biters, killing them, and still destroy/damage one more target.

== Resistance ==
Resistances to specific damage types can be written in two ways:

* A percentage, such as: "Physical: 10%". The incoming damage of this type is simply reduced by this percentage.
* A flat decrease, followed by the percentage, such as: "Physical: 25/10%". This means that incoming damage is reduced by 25 points first, before reducing it by 10%.

Shooting at an object with a physical resistance of "25/10%" has nearly no effect when the bullets inflict less than 25 damage points each. If each bullet does 45 damage points, then the resistance of 25 is subtracted first, and the remaining 20 damage points are reduced by 10%, resulting in 18 damage points being imparted on the target object.

The following two subsections explain the two resistance calculations in detail.

=== Decrease, or "flat" resistance ===
Decrease resistance decreases the damage by specified number as long as the resulting damage wouldn't be less than 1. If the result damage would be less than 1, an alternate formula is used.
Let R denote the flat resistance value, D the incoming damage, and M the modified damage (that is, the damage after accounting for flat resistance). Then

if R+1<D

<code>M=D-R</code>

otherwise if D>1

<code>M=1/(R-D+2)</code>

otherwise

<code>M=1/(R+1)</code>.

If flat resistance matches or exceeds the raw damage, then modified damage is asymptotic towards 0, as shown by following example table:

{| class="wikitable"
|-
! Damage !! Flat Resistance !! Modified damage (with 0% resistance)
|-
| 5 || 0 || 5
|-
| 5 || 1 || 4
|-
| 5 || 2 || 3
|-
| 5 || 3 || 2
|-
| 5 || 4 || 1
|-
| 5 || 5 || 1/2
|-
| 5 || 6 || 1/3
|-
| 5 || 7 || 1/4
|-
| 5 || 8 || 1/5
|-
| ... || ... || ...
|}

=== Percentage resistance ===

Percentage resistance reduces the damage by the specified percent. It is applied ''after'' flat/decrease resistances (if both are present) and thus changes the 'modified damage' value above, decreasing it by the specified percentage. If the value is 100%, the entity is immune to the damage. This is the only way to have an entity immune to a type of damage, as flat reduction cannot reduce damage to less than 1.

As an example, an entity with 25% resistance to physical damage hit with a bullet dealing 100 physical damage would take 75 damage instead of 100.

The formula used for percentage resistance to damage is as follows:

Let M denote the flat-resistance-modified starter damage, and let P denote the percentage resistance (in decimal form, so 25%=0.25), and let F denote final damage.

<code>F = M * (1 - P)</code>

== Combined formulas ==
Let D denote the raw incoming damage (of applicable type), R denoted the flat resistance value (against damage of the applicable type), P the percentage resistance (against damage of the same type) in decimal form (e.g. 20%=0.2), and let F denote the final damage (of applicable type) dealt to the target.
=== If R+1<D ===
F = (D - R) * (1 - P)
=== otherwise if D>1 ===
F = (1 - P) / (R-D+2)
=== otherwise ===
F = (1 - P) / (R+1)

=== Multiplayer ===

--start-server SAVE

Will start a Headless (Dedicated) server, with no GUI.

--mp-connect ADDRESS
ADDRESS is the IP:port of the remote host. Port is optional.
Examples:

./factorio --mp-connect 192.168.1.101
./factorio --mp-connect 192.168.1.101:2345

As above, port can be specified by placing the port number after a colon in the address.

=== Creating a map from custom settings ===

Sometimes it's useful to create a new game with map and/or map generator settings stored in a JSON file rather than going through the in-game map settings screen.
One reason is that by editing the settings directly it is possible to set settings outside the range normally available from the GUI.

To do this, Factorio is run from the command-line, and a JSON file containing the map generator settings and a JSON file containing map settings (if customizing them) are needed.

Example for custom generator settings:
<pre>{
"terrain_segmentation": 0.5,
"water": "2",
"width": 0,
"height": 0,
"starting_area": "normal",
"peaceful_mode": false,
"autoplace_controls":
{
"coal": {"frequency": 1, "size": 2, "richness": 0.5},
"copper-ore": {"frequency": "low", "size": "normal", "richness": "high"},
"crude-oil": {"frequency": "normal", "size": "normal", "richness": "normal"},
"enemy-base": {"frequency": "normal", "size": "normal", "richness": "normal"},
"iron-ore": {"frequency": "normal", "size": "normal", "richness": "normal"},
"stone": {"frequency": "normal", "size": 0, "richness": "normal"},
"uranium-ore": {"frequency": "normal", "size": "none", "richness": "normal"}
},

"cliff_settings":
{
"name": "cliff",
"cliff_elevation_0": 30,
"cliff_elevation_interval": 20,
"richness": 1
},

"property_expression_names":
{
"elevation": "0_16-elevation",
"temperature": "35"
},

"seed": null
}
</pre>

Note that this is the same format as [https://lua-api.factorio.com/latest/Concepts.html#MapGenSettings MapGenSettings] that are modifiable from Lua. Everything in the file is optional.

Creating a custom save:
<pre>
"C:\Program Files\Factorio\bin\x64\Factorio.exe" --create stuff-seed123.zip --map-gen-settings map-gen-settings.json --map-gen-seed 123
</pre>

Generating a map preview:
<pre>
"C:\Program Files\Factorio\bin\x64\Factorio.exe" --generate-map-preview preview-seed123.png --map-gen-settings map-gen-settings.json --map-gen-seed 123
</pre>

==== Creating the JSON files from a map exchange string ====

It can be useful to create the initial JSON files from a known map exchange string instead of creating them from scratch. To convert the map exchange string to JSON, open the game and run the following command with your map exchange string:

/c game.write_file('map.txt', game.table_to_json(game.parse_map_exchange_string(<your exchange string here>)))

Then open the script_output folder in the [[user data directory]] and open map.txt - it will look like this:

{"map_settings":{ ...<MAP_SETTINGS> ... },"map_gen_settings":{ ...<MAP_GEN_SETTINGS>... }}

Copy the { ...<MAP_SETTINGS> ... } section into a new file called 'map-settings.json' in the desired location. Copy the { ...<MAP_GEN_SETTINGS> ... } section section into a new file called 'map-gen-settings.json' in the desired location.

== Multiplayer changes ==

Hi
i can see you removed a change i made on the page (multiplayer) with the reason it was not linux commands. i will inform you if i wrote these commands in the part that belongs to a windows setup and actually just under one of the things i made about there was a title called "Setting up a Linux Factorio server" which i did not change. i dont see what you mean by it is not linux commands as that part does not belong to a linux setup

[https://wiki.factorio.com/Multiplayer multiplayer]
[https://wiki.factorio.com/Multiplayer#Setting_up_a_Linux_Factorio_server Setting up a Linux Factorio server]

: Hi Thejomper. First off, I'm sorry this happened! I'll explain my reasoning a bit better than in the commit message / changelog. I should also preface this by saying that I have very little experience having discussions in this sort of multiplayer notepad with magic syntax, so please let me know if I reply in an incorrect manner.

: The section is "dedicated/headless server", which is only available for Linux. The command examples shown are <tt>./bin/x64/factorio --start-server [etc.]</tt> which only works using the Linux release of the game (indeed, the headless server is for Linux). For Windows, it would be <tt>bin/x64/factorio.exe</tt> (and the <tt>start</tt> command that you added is optional, depending on what behaviour the user wants). Since the commands are used to run a Linux server using a binary that exists only for Linux, I think it would be wrong to add a "start" command that only works on Windows (and is optional even there).

: You added another example that uses "pause", which is also Windows-only, but didn't change bin/x64/factorio to bin/x64/factorio.exe, so again this example will not work on any platform. And even if you make it work on Windows, it seems to me that this would be the wrong section.

: Finally, you added a hint about where to find a certain file... specifically for Windows. If a Windows user can't find this path, they would be unlikely to check the section about the dedicated linux-only server and more likely to search the wiki for "settings directory" which will land them on the dedicated page where it is explained multi-platform: [[Application directory]].

: In short, my reason for reverting was to revert the page state to a state where the examples actually work on the platform for which they were intended.

: I'm sorry I reverted most of your edit. I did look at each change and kept the part that I assume works on all platforms ("This file will be created if you promote a player through the console"), that was a helpful addition because I didn't know that yet!

: If you want to add examples on how to manage a Windows server, I think a different or new subsection would be more fitting. Section 1 of the page is "Setting up a multiplayer game" with subsections "1.1 dedicated/headless server" (linux-only), "1.2 Setting up a Linux Factorio server", and 1.3+ with more details about other server-related topics. Maybe your examples would fit better in a new section (inserted above or below the linux server sections) like "Setting up a Windows server".

: I hope this explained my reasoning! [[User:Luc|Luc]] ([[User talk:Luc|talk]]) 20:14, 3 March 2020 (UTC)

Luc: Undo revision 178069 by Thejomper (talk) "start" and "pause" are not a thing on linux. Maybe you want to add a variant for Windows with factorio.exe? As it is, this doesn't work on any platform.

{{Languages}}
In addition to being a single-player game, Factorio also supports multiplayer, allowing many players to cooperate and assist each other, or work against each other in pvp. This page documents how to set up a multiplayer game, how to join one, and the Multiplayer Admin features for managing other users and the server. By default, multiplayer games run the CO-OP [[Game modes and options|freeplay scenario]] where all players work together to launch a rocket with a satellite into space. Other scenarios, including PvP maps, are available for download from the [https://forums.factorio.com/viewforum.php?f=36&sid=93d1fbe9336d31d6bac60847b6c97985 Maps and Scenarios forum].

== Setting Up a Multiplayer Game ==

[[File:multiplayer_game_night.png|thumb|250px|A multiplayer game.]]Multiplayer games can be joined, hosted while playing, or hosted by a dedicated server. Multiplayer games can be advertised to other players on the same LAN or worldwide.

Use the ''Multiplayer'' button in the ''Play'' menu to start playing a multiplayer game, choose ''New'' or ''Load'' or ''Scenarios'' to host and play, or ''Browse'' or ''Play on LAN'' to connect to an already-running game. The host can also choose not to advertise the game at all, in which case you'll need the server's (public or otherwise reachable) IP address; you can then ''Connect'' directly to that to join the game.

Notes and tips:

* All game instances need the installation of ''exactly the same'' game-versions and mods.
* Factorio servers use port '''34197'''. The port can be changed in the [[Application directory|config]] file.
* Factorio uses '''UDP only'''. The game builds its own "reliable delivery" layer built on UDP to deal with packet loss and reordering issues.
** Make sure you configure your router's port forwarding correctly for port '''34197'''.
** Make sure your router does not [https://doc.pfsense.org/index.php/Static_Port randomize the source port] on packets outbound from '''34197'''. Some routers do this and require [https://forum.pfsense.org/index.php?PHPSESSID=3k4h9n5o2tksgqv910fknf7qt7&topic=142188.msg798594#msg798594 additional configuration] to prevent it.
** Make sure there is no firewall or anti-virus blocking the UDP-packets.
* The hard limit for the number of players is [https://forums.factorio.com/viewtopic.php?f=53&t=6481&p=50661#p50586 65,535]. However, practical limit for this is much lower, popular streamers have managed slightly over a hundred players.

=== Dedicated/Headless server ===

As of Factorio version 0.12.0 onwards, a dedicated (or headless) server can be started using the --start-server command line option. You can run factorio --help to get a list of all command-line arguments that Factorio accepts.

In the headless mode:
* Graphics are not initialized (faster start up, less memory usage, works on completely headless servers)
* Game starts immediately and loads a save given as a parameter to the command
* The server has no character in game
* Game is paused while there are no players connected (though this can be overridden using the no-auto-pause option in the server-settings.json)
* Saves the game on exit (and autosaves normally)

''0.13 onwards expects --start-server to be followed by a path to a save file.''

You will need to create your save file before you start the server, as the dedicated server REQUIRES a save file to be provided. This can easily be done using the --create command-line argument. For example:

<pre>
./bin/x64/factorio --create ./saves/my-save.zip # This creates a new save, as if by clicking the New Game button in the GUI
</pre>

<pre>
./bin/x64/factorio --start-server ./saves/my-save.zip # This starts a server that will host the file created on the previous line
</pre>

There are several JSON configuration files that factorio can make use of to change the server and map settings:
* '''map-gen-settings''' to set parameters used by the map generator such as width and height, ore patch frequency and size, etc. (Added in 0.13)
* '''map-settings''' to control pollution spread, biter expansion and evolution, and more (Added in 0.15)
* '''server-settings''' which consolidated several command-line options into a single file (Added in 0.14.12)
Example files for each of these parameters are included in the data subdirectory.

The --map-gen-settings and --map-settings options must be used with the --create option when you create a new map. For example:
<pre>./bin/x64/factorio --create saves/my-save.zip --map-gen-settings my-map-gen-settings.json --map-settings my-map-settings.json</pre>

Starting the factorio server requires you to specify the location of the server-settings.json file. By default this is in the factorio data folder. For example to start factorio using the most recent saved map, you would run:

<pre>./bin/x64/factorio --start-server-load-latest --server-settings ./data/server-settings.json</pre>

''See [[Command_line_parameters]] for more command line parameters.''

=== Setting up a Linux Factorio server ===

'''Note:''' Factorio now requires <tt>glibc</tt> version 2.18, but CentOS/RHEL 7 only ship with version 2.17 so this guide will no longer work without [https://forums.factorio.com/viewtopic.php?t=54654#p324493 manually compiling <tt>glibc</tt> 2.18].

This step-by-step guide has been verified on fresh CentOS 7 and RHEL 7 installs but should be applicable with little to no changes on most distributions.

The guide assumes you will install the headless server under '''/opt/factorio''', adjust paths according to your own setup. We will also suggest that you run the Factorio server as a separate user to harden security of your setup.

Note that there are two distinct packages for Linux that can be used to run a headless server. First is the usual Linux download, that contains the full game. The other is the special [https://www.factorio.com/download-headless headless package]. The headless package does not contain any files irrelevant for a pure server, such as graphics and sounds. It is also not linked against libraries that may not be present on a server machine, such as Xlib, libGL or libasound. This option should be selected if running in a 3rd party hosted server.

This guide does not handle firewall/port forwarding since this can be done in various ways on Linux (make sure to read up how this is done as a Linux admin on your particular distribution)

==== Basic installation ====

* Download the selected package -- either full game or the headless package -- and upload the Linux tar.gz or tar.xz package to your server /tmp
* Extract the package in /tmp to /opt/factorio
<pre>
$cd /opt/

$sudo tar -xzf /tmp/factorio.tar.gz # Use the correct file name. It includes the factorio version number
$sudo tar -xJf /tmp/factorio.tar.xz # if you downloaded a .tar.xz file (ver 0.15.x)</pre>

* Add a new user to your system and assign ownership of the factorio dir to it (please, do not run as the root user, sudo may be needed)
<pre>
$useradd factorio
$chown -R factorio:factorio /opt/factorio</pre>

* Try the binary
<pre>
$su factorio
$/opt/factorio/bin/x64/factorio --start-server savename</pre>

As long as it fails saying it cannot find/open the savename.zip you are set! Just upload a save from your own computer and put it in the /opt/factorio/saves directory, or use the --create ./saves/newgame.zip argument.

==== Additional configuration ====

You can use a [https://github.com/Bisa/factorio-init Linux factorio-init script] to start/stop your headless server in a much better way. The script will ensure you only ever use the most recent save when your server starts (even if that was an auto-save) while also letting you set a number of other settings like Autosave frequency and Latency settings. This script can also simplify updating the server when combined with a [https://github.com/narc0tiq/factorio-updater Linux factorio-updater script].

Additionally, if you plan to enable mods on your server a mod updater script can greatly simplify this process. Here are several existing options, or you can write your own!
* [https://github.com/pdemonaco/factorio-mod-updater Python Mod Updater]
* [https://github.com/astevens/factorio-mod-updater Ruby Mod Updater]

=== How to list a server-hosted game on the matching server ===

In order to publish the game to the matching server, Factorio needs to be given some more information than just the save file location. These information are provided in a ''server settings file''.

To create a server settings file, look at the example file located in '''data/server-settings.example.json''' in the Factorio [[Application directory]]. The recommended way is to make a copy of this example file and edit the copy.

The following values can be changed:
; Name: This will be the name under which the server will be listed in the server browser
; Description: A brief description of your server
; Tags: A list of game tags
; Max Players: Allows you to limit the number of players that can be connected to the server at the same time. If you want no limit, just set max_players to 0.
* Visibility for server browser: May be either public, LAN or hidden.
** Public: The server will appear in the public server list. This requires the login credentials below to be filled in.
** LAN: The server will not appear in the public server list, but will be available through the Play On LAN button
** Hidden: Clients will have to connect using the server's IP address
* User credentials using a username and password or authentication token (found on the factorio website or in the player-data.json): These are necessary if you wish to make the server public. Otherwise, they can be left empty.
** For security reasons it is recommended to use authentication token as this document is stored as plain text. Though it should be noted that an authentication token is a sensitive piece of information as well, and you are well-advised to keep it secret.
* Server Password
** Field name is game_password
* Whether to verify user identity
(There are additional values in v0.14 of factorio.)

=== Technical Implementation Details ===

Notes about some technical details surrounding multiplayer have been published by the development team in several Friday Facts blog posts:

=== Miscellaneous Tips ===
* The key for [[Console|console commands]] is also used initiate chat in multiplayer. To execute a command instead of chatting, you need to type ''/c'' before the command. Commands executed are ''visible to all players''. Additionally, the multiplayer game must have been started with commands allowable for commands to work.
* Set the player's color using the command
/color r g b a
r, g and b are for red, green and blue respectively (possible values are between 0 and 1, use [https://www.w3schools.com/colors/colors_converter.asp this site] to convert colors to rgb numbers). a is alpha channel aka transparency of the color to the base texture.
* To give yourself admin access, you need to create a server-adminlist.json in the same directory as factorio-current.log. The file should contain a list of admins, like so: <code>[ "user1", "user2" ]</code>

This file will be created if you promote a player through the console.

== Joining a Multiplayer game ==

As of version 0.13, players no longer necessarily have to port-forward to play with others. Players may join each other through Steam, or by just the port-forwarded host.

Players wishing to join a game may do so in multiple ways:

* Joining by directly inputting a public IP and port into Factorio.
* Selecting the server from the active public server menu.
* Joining through Steam's services.
* Playing a local LAN game.

=== Joining by IP ===

To join a multiplayer game by IP, you will need to know the public IP of a valid server. You can find this through social media, websites, or by word of mouth. After acquiring the IP and port, simply go to play -> Multiplayer -> Connect to server, and provide all the information it asks for.

If the server has been set up correctly to accept public connections, you should be able to join the game.

=== Joining via server list ===

Factorio's devs keep a list of all public servers that declare themselves to the service, allowing players to join directly through Factorio. Most of these servers will be password-requiring, but many completely public servers can be connected to. To join via server list, go to Play -> Multiplayer -> Browse public games. Provide your Factorio.com login if asked, and a list of public servers will appear. Simply select one.

=== Joining through Steam ===

Steam provides a "game invite" system, simply use that to join. You can find more info about how to use steam in it's documentation. ''This is the most recommended way for the average player to use multiplayer with their friends, as it allows Steam to handle everything''.

=== Joining a local LAN game ===

If you have some friends on the same internet connection as you (in the same building or network), you may play a LAN game. Simply go to Play -> Multiplayer -> Play on LAN.

=== Finding Other Players ===

* Use the [https://forums.factorio.com/viewforum.php?f=53 multiplayer board in the forum].
* Many players use other software like Evolve to meet other players. This also has the "advantage" of creating a virtual LAN among the players. See down under software.
* Some also use [https://forums.factorio.com/viewtopic.php?f=5&t=9136 Steam] to find other players.
* There is an external [http://serverlist.lgms.nl/ server browser] with various search options.
* Tell your friends to buy Factorio, then play with them!

=== Connecting to a Server Behind NAT ===

Factorio requires that the server (in client-server mode) have a publicly accessible IP address or that all players are on the same LAN. If you are behind NAT, you must set up port forwarding ([[Multiplayer#Playing_over_LAN_.2F_Internet|see above]] for port number) or use virtual LAN software such as Hamachi or Evolve.

Multiplayer games will be launched in client-server mode (also [http://www.factorio.com/blog/post/fff-99 multiplayer forwarding] mode). In this mode, all clients send their network traffic to the server and the server forwards the traffic to the other clients. The advantage of this is that it allows games where some players are inside a LAN and others are outside. The disadvantage may be slightly more lag as packets must travel an extra hop (through the server).

* [http://steamcommunity.com/sharedfiles/filedetails/?id=653628496 A guide for connecting with Hamachi]

== PvP ==

In PvP mode, players can be on different forces. Each force can have one (free-for-all) or more players (teams). Each force has its own independent research progression. Additionally, each force's [[Military units and structures]] will attack other players as enemies, unless a cease fire is set. Note that, depending on the scenario, cease fires may be unidirectional — setting a cease fire with an opposing force does not guarantee a cease fire from them in return.

To start a PvP game, you can select the 'PvP' scenario from the 'Play' menu, or download a custom scenario which also supports PvP.

After downloading a PvP scenario, you need to move it to your application directory, and create the multiplayer game using the scenario.

# Download the scenario and place the scenario directory in the ''scenarios'' directory within your [[Application_directory#Directory_locations_by_OS_and_installation_method|user data directory]].
# Launch Factorio
# Click ''Play''
# Click ''Multiplayer''
# Click ''Scenario''
# Choose the PvP scenario you want and click ''Create''
# Choose latency and other settings, then click ''Play''
# Other players can now join the game

=== Forces ===

Forces can be manually created via the console. This allows any map/scenario to be used for PvP. This may not be as convenient as a pre-made PvP scenario, as there will be no way for players to turn on/off cease fires other than through the console.

Each created force has its own research progression and different forces may attack each other.

The console commands for setting up and controlling forces are below:

<pre>
game.create_force("Name")
--Creates the force "Name"

game.players["Player_name"].force = game.forces["Name"]
--Sets this player to the new force

game.forces["Name"].set_cease_fire("Other_force_name", true)
--Sets the new force ceasefire to the "other force"

game.forces["Name"].set_spawn_position({x = 10, y = 20}, game.surfaces[1])
--Sets the spawn position of the force

game.print(#game.forces)
--Prints the number of forces

for name, force in pairs (game.forces) do
game.print(name)
end
--Prints the name of all the forces
</pre>

The ability of players and entities belonging to one force to interact with structures belonging to another, non-friendly force is limited. However, some types of interactions are still possible:

;Manual pickup from belts
: Players can pick up items traveling along a transport belt that belongs to an opposing force. Note however that this can't be automated: Inserters will ''not'' take items from an opposing force's belts.
;Belt network connection
: Belts will connect to each other regardless of force membership, so it's possible to extend an opposing force's belt line, and items will flow to them. It is also possible to side-load into, and place items onto (with inserters) an opposing force's belt line.
;Fluid network connection
: Pipes (and storage tanks, and pumps, &c) will connect to each other regardless of force membership. For example, it's possible to pump fluids out of or into a storage tank belonging to an opposing force.
;Power leeching
: Players can draw power from an opposing force's electric network, by building structures inside the coverage area of a power pole belonging to an opposing force. Power poles that you build next to a power pole belonging to an opposing force will automatically connect to it, but will be impossible to connect or disconnect manually.

== History ==

=== Narrative history ===

Because of the potentially immense amount of activity on a map, the game engine utilizes a [https://www.factorio.com/blog/post/fff-76 lock step architecture]. All instances of the game run full simulations of the entire world and only player actions are transferred across the network.

Multiplayer games were introduced to Factorio with version 0.11.0. The only connection method available was peer-to-peer mode which meant every player had to be able to directly communicate with every other player. In version 0.12.4, a client-server mode of communication was introduced in which the server (either a dedicated one or the player who hosted the game) relays messages to all peers. This means that direct connection between all players is no longer necessary. As of version 0.13, P2P connecting is completely removed.

As of version 0.12.0, the game features "latency hiding" mechanics where the game simulates some of the player's actions locally to make some common interactions (such as moving the player's character) more fluid. Not every action is a part of latency hiding – most notably, car or train driving and shooting are not a part of it.

=== Version history ===

Console

2018-12-23T15:39:18Z

Luc: Add command for killing nearby enemies (I wanted enemies generally on the map, but got tired of making space for a huge solar array)

{{Languages}}
== Overview ==
The '''Console''' is Factorio's command-line interface.

The in-game console is used for:

* Chatting with other players
* Running commands / scripts / cheats
* Occasional status updates

There are three types of commands:

* '''[[#Normal commands|Normal]]''' - Display information about the game and customize your experience.
* '''[[#Multiplayer commands|Multiplayer]]''' - Message filtering, banning users, etc.
* '''[[#Scripting and cheat commands|Scripting/Cheating]]''' - Run small Lua scripts (but they <span style="color:#FF0000">disable achievements for the save game</span>)

=== Using the console ===
The console display can be toggled with the {{keybinding|/}} (slash) or {{keybinding|~}} (tilde) keys.

You can customize the keys via '''Options Menu → Keyboard → Toggle Lua console'''.
When the console is open, you'll see a blinking cursor at the bottom of the screen; type your message or command and hit '''Return''' to send it (this will also close the console).
Documentation about message and command prefixes can be found further down this page.

When console is closed, only the most recent messages/commands will be displayed, but they will gradually fade away (opening the console will immediately re-display all recent messages).
Note that by default, all executed commands are made visible to all users. You can set the fade out time via '''Options Menu → Other Settings → Message Delay'''.

If you want to immediately hide the console, open the console and then press '''Escape''' key (or press '''Return''' without entering any message/command).
This not only closes the console, but it also hides all the recent messages/commands.
The console can be cleared with the '''/clear''' command.

Note that the console can also accept raw Lua code as well as game commands.

=== Console history ===

The console has an inbuilt history; it's a bit like a text editor where only one line of text is displayed at a time.

Use the {{keybinding|↑}} and {{keybinding|↓}} keys to scroll through the console history.

Use the {{keybinding|←}} and {{keybinding|→}} keys to cursor through the currently displayed message or command, which you can edit (delete, insert, etc.) and resend (by pressing '''Return''').

The {{keybinding|Tab}} key will auto-complete commands and player ids.

This is a very powerful feature, which also allows cheating, and as such <span style="color:#FF0000">achievements will be permanently disabled for the save</span> as soon as you use a script command.

== Basic example scripts ==

=== Use it as calculator ===
<syntaxhighlight lang="lua">
/c game.player.print(1234*5678)
</syntaxhighlight>

=== Zoom beyond normal bounds ===
Note that zooming too far out can cause performance hits. Be careful.
<syntaxhighlight lang="lua">
/c game.player.zoom=0.1
</syntaxhighlight>

=== Mine faster ===
<syntaxhighlight lang="lua">
/c game.player.force.manual_mining_speed_modifier=1000
</syntaxhighlight>

=== Craft faster ===
<syntaxhighlight lang="lua">
/c game.player.force.manual_crafting_speed_modifier=1000
</syntaxhighlight>

=== Unlock and research all technologies ===
<syntaxhighlight lang="lua">
/c game.player.force.research_all_technologies()
</syntaxhighlight>

Undo this with the command in the next section.

=== Unresearch all technologies ===
This does not reset manually applied bonuses
<syntaxhighlight lang="lua">
/c for _, tech in pairs(game.player.force.technologies) do
tech.researched=false
game.player.force.set_saved_technology_progress(tech, 0)
end
</syntaxhighlight>

=== Cancel current research ===
Cancels the current research.
<syntaxhighlight lang="lua">
/c game.player.force.current_research = nil
</syntaxhighlight>

=== Reset your force ===
This resets all data for your force, including kill and production statistics, technologies, bonuses and charting status.
<syntaxhighlight lang="lua">
/c game.player.force.reset()
</syntaxhighlight>

=== Always show rail block visualization ===
Permanently show the rail block visualization instead of only when holding a rail signal. Disable by replacing true with false.

<syntaxhighlight lang="lua">
/c game.player.game_view_settings.show_rail_block_visualisation = true
</syntaxhighlight>

== Inventory manipulation scripts ==

=== Cheat mode ===
Allows for infinite free crafting. Disable by replacing true with false.
<syntaxhighlight lang="lua">
/c game.player.cheat_mode=true
</syntaxhighlight>

=== Refill resources (refill oil, iron etc.) ===
While holding the cursor over a resource tile in-game
<syntaxhighlight lang="lua">
/c game.player.selected.amount=7500
</syntaxhighlight>

Alternatively you can refill all resources in the map with the following command. Change ore.amount to the desired value.
<syntaxhighlight lang="lua">
/c surface = game.player.surface
for _, ore in pairs(surface.find_entities_filtered({type="resource"})) do
ore.amount = 10000
end
</syntaxhighlight>

=== Add items to the player's inventory ===
Replace iron-plate with the [[data.raw|internal name]] of the item desired.
<syntaxhighlight lang="lua">
/c game.player.insert{name="iron-plate", count=100}
</syntaxhighlight>

For instance, here's a stack of the god-mode energy system interface:
<syntaxhighlight lang="lua">
/c game.player.insert{name="electric-energy-interface"}
</syntaxhighlight>

Add a powerful armor with equipment and some tools for construction:
<syntaxhighlight lang="lua">
/c local player = game.player
player.insert{name="power-armor-mk2", count = 1}
local p_armor = player.get_inventory(5)[1].grid
p_armor.put({name = "fusion-reactor-equipment"})
p_armor.put({name = "fusion-reactor-equipment"})
p_armor.put({name = "fusion-reactor-equipment"})
p_armor.put({name = "exoskeleton-equipment"})
p_armor.put({name = "exoskeleton-equipment"})
p_armor.put({name = "exoskeleton-equipment"})
p_armor.put({name = "exoskeleton-equipment"})
p_armor.put({name = "energy-shield-mk2-equipment"})
p_armor.put({name = "energy-shield-mk2-equipment"})
p_armor.put({name = "personal-roboport-mk2-equipment"})
p_armor.put({name = "night-vision-equipment"})
p_armor.put({name = "battery-mk2-equipment"})
p_armor.put({name = "battery-mk2-equipment"})
player.insert{name="construction-robot", count = 25}
player.insert{name="blueprint", count = 3}
player.insert{name="deconstruction-planner", count = 1}
player.insert{name="steel-axe", count = 10}
</syntaxhighlight>

== World manipulation scripts ==

=== Reveal the map around the player ===

Reveals the map around the player, similar to a [[radar]].
<syntaxhighlight lang="lua">
/c local radius=150
game.player.force.chart(game.player.surface, {{game.player.position.x-radius, game.player.position.y-radius}, {game.player.position.x+radius, game.player.position.y+radius}})
</syntaxhighlight>
or from start position
<syntaxhighlight lang="lua">
/c game.forces.player.chart(game.player.surface, {{x = -2000, y = -2000}, {x = 2000, y = 2000}})
</syntaxhighlight>
Change 150 to the desired radius, higher values take longer.

=== Delete chunks ===
If much of the map is revealed, it increases the size of the save file. The following command cancels the generation of all chunks that are currently queued for generation and removes chunks outside a 32 chunks radius around 0,0. Note that this will remove player entities if there are any on these chunks.
<syntaxhighlight lang="lua">
/c local surface = game.player.surface;
game.player.force.cancel_charting(surface);
local chunk_radius = 32;
for chunk in surface.get_chunks() do
if (chunk.x < -chunk_radius or chunk.x > chunk_radius or chunk.y < -chunk_radius or chunk.y > chunk_radius) then
surface.delete_chunk(chunk)
end
end
</syntaxhighlight>

=== Turn off night ===
Enables eternal day.
<syntaxhighlight lang="lua">
/c game.player.surface.always_day=true
</syntaxhighlight>

=== Change game speed ===
0.5 is half speed, 1 is default, 2 is double speed, etc. Minimum is 0.01. This can be used for a lot of things like when you know you will have to wait for long periods of time for something to complete. Increasing will decrease performance, be careful.
<syntaxhighlight lang="lua">
/c game.speed=X
</syntaxhighlight>

=== Expensive (marathon) or normal mode ===
To change from normal to expensive mode preset (this changes the research cost and intermediate product cost):
<syntaxhighlight lang="lua">
/c game.difficulty_settings.recipe_difficulty=1
game.difficulty_settings.technology_difficulty=1
game.difficulty_settings.technology_price_multiplier=4
</syntaxhighlight>

To change back to normal:
<syntaxhighlight lang="lua">
/c game.difficulty_settings.recipe_difficulty=0
game.difficulty_settings.technology_difficulty=0
game.difficulty_settings.technology_price_multiplier=1
</syntaxhighlight>

=== Freeze time ===
Stops the advancement of the time if you replace "BOOL" with "true" or unfreezes it if you replace it with "false".
<syntaxhighlight lang="lua">
/c game.player.surface.freeze_daytime=BOOL
</syntaxhighlight>

=== Remove all pollution ===
<syntaxhighlight lang="lua">
/c game.player.surface.clear_pollution()
</syntaxhighlight>

=== Completely turn off pollution ===

<syntaxhighlight lang="lua">
/c for _, surface in pairs(game.surfaces) do
surface.clear_pollution()
end
game.map_settings.pollution.enabled = false
</syntaxhighlight>

=== Add a lot of pollution ===
<syntaxhighlight lang="lua">
/c game.player.surface.pollute(game.player.position, 1000000)
</syntaxhighlight>

=== Disable friendly fire for your force ===
<syntaxhighlight lang="lua">
/c game.player.force.friendly_fire = false
</syntaxhighlight>

=== Add new resource patch ===
This creates a new 11×11 patch of resources, centered on the player character, where the ground is not water.
The patch it creates is perfectly square but it randomizes the amount similar to natural generation, with fewer ore at the edges and more ore in the center.
The default numbers result in a patch with 2500-3000 ore.

If you want a larger patch, change "local size = 5" to a larger number.
A larger patch will have exponentially more ore.
Entering a number above 30 is not recommended.

If you want a richer patch, change "local density = 10" to a larger number.
Entering a very large number shouldn't hurt anything but you probably don't need to go above 100.

To choose which resource is spawned, change "stone" near the bottom to "iron-ore", "copper-ore", "coal", or "uranium-ore".

<syntaxhighlight lang="lua">
/c local surface=game.player.surface
local ore=nil
local size=5
local density=10
for y=-size, size do
for x=-size, size do
a=(size+1-math.abs(x))*10
b=(size+1-math.abs(y))*10
if a<b then
ore=math.random(a*density-a*(density-8), a*density+a*(density-8))
end
if b<a then
ore=math.random(b*density-b*(density-8), b*density+b*(density-8))
end
if surface.get_tile(game.player.position.x+x, game.player.position.y+y).collides_with("ground-tile") then
surface.create_entity({name="stone", amount=ore, position={game.player.position.x+x, game.player.position.y+y}})
end
end
end
</syntaxhighlight>

=== Add new oil patch ===
This creates 9 crude oil patches in a 3×3 square.
<syntaxhighlight lang="lua">
/c for y=0,2 do
for x=0,2 do
game.player.surface.create_entity({name="crude-oil", amount=100000, position={game.player.position.x+x*7-7, game.player.position.y+y*7-7}})
end
end
</syntaxhighlight>

or randomly without any collision:
<syntaxhighlight lang="lua">
/c local position=nil
for i=1,9 do
position=game.player.surface.find_non_colliding_position("crude-oil", game.player.position, 0, i/2+1.5)
if position then
game.player.surface.create_entity({name="crude-oil", amount=100000, position=position})
end
end
</syntaxhighlight>

=== Count entities ===
Counts all entities whose name includes the string in local entity.
<syntaxhighlight lang="lua">
/c local entity="belt"
local surface=game.player.surface
local count=0
for key, ent in pairs(surface.find_entities_filtered({force=game.player.force})) do
if string.find(ent.name,entity) then
count=count+1

=== Emptying all pipes, underground pipes and pumps ===
Useful when pipes contain a fluid you dont want.
<syntaxhighlight lang="lua">
/c local surface = game.player.surface
local deleted=0
for key, entity in pairs(surface.find_entities_filtered({force=game.player.force})) do
if string.find(entity.name, "pipe") or
string.find(entity.name, "pump")
then
for i=1,#entity.fluidbox do
deleted = deleted + 1
entity.fluidbox[i] = nil;
end
end
end
game.player.print("Fluids removed from "..deleted .." entities")
</syntaxhighlight>

=== Turn off cliff generation ===
Sets size to "none". Only effective on chunks that are generated after using this command. Use [[#Remove all cliffs]] to delete existing cliffs.

<syntaxhighlight lang="lua">
/c local mgs = game.player.surface.map_gen_settings
mgs.cliff_settings.cliff_elevation_0 = 1024
game.player.surface.map_gen_settings = mgs</syntaxhighlight>

=== Remove all cliffs ===
Removes all cliffs existing cliffs from the world. Use [[#Turn off cliff generation]] to turn off cliff generation in new chunks.

<syntaxhighlight lang="lua">
/c for _, v in pairs(game.player.surface.find_entities_filtered{type="cliff"}) do
v.destroy()
end</syntaxhighlight>

=== Delete all decoratives ===
Delete the decoratives that can be found in the world.

<syntaxhighlight lang="lua">
/c local surface = game.player.surface
for c in surface.get_chunks() do
surface.destroy_decoratives({{c.x*32, c.y*32}, {c.x*32+32, c.y*32+32}})
end</syntaxhighlight>

=== Change map generation settings ===
This allows to change the map generation settings for new chunks; it does not alter already generated chunks. [[#Delete chunks|Deleted chunks]] are affected by the setting change because they are newly generated when they get explored again.

To change resource generation settings, replace "iron-ore" with the [[Data.raw#resource|resource]] that should be changed and replace "very-high" with the desired [https://lua-api.factorio.com/latest/Concepts.html#MapGenSize MapGenSize] in the following command. Replace "iron-ore" with "enemy-base" to change the enemy base generation settings.

<syntaxhighlight lang="lua">
/c local surface = game.player.surface
local resource = "iron-ore"
local autoplace = surface.map_gen_settings.autoplace_controls
autoplace[resource].size = "very-high"
autoplace[resource].frequency = "very-high"
autoplace[resource].richness = "very-high"
surface.map_gen_settings.autoplace_controls = autoplace</syntaxhighlight>

To change water generation settings, replace "very-high" with the desired [https://lua-api.factorio.com/latest/Concepts.html#MapGenSize MapGenSize] in the following command.

<syntaxhighlight lang="lua">
/c local surface = game.player.surface
local mgs = surface.map_gen_settings
mgs.water = "very-high" -- size
mgs.terrain_segmentation = "very-high" -- frequency
surface.map_gen_settings = mgs </syntaxhighlight>

== Enemy/evolution scripts ==

=== Set evolution factor ===
Ranges from 0 (new game) to 1.
<syntaxhighlight lang="lua">
/c game.forces["enemy"].evolution_factor=X
</syntaxhighlight>

=== Disable time-based evolution & increases pollution-based evolution ===
<syntaxhighlight lang="lua">
/c game.map_settings.enemy_evolution.time_factor=0
/c game.map_settings.enemy_evolution.pollution_factor=game.map_settings.enemy_evolution.pollution_factor*2
</syntaxhighlight>

The "2" at the end of the last command will double the default pollution factor. You can substitute another number to increase (or decrease) the pollution factor further.

=== Kill all biters on the "enemy" force ===
Note that this will kill only mobile units, spawners will not be killed.
<syntaxhighlight lang="lua">
/c game.forces["enemy"].kill_all_units()
</syntaxhighlight>

=== Kill all enemies ===
This will kill all biters, bases and worms. Anything that is an enemy will be completely destroyed. This only affects enemies in the explored world, so any unexplored parts of the map which still need to be generated will still have enemies.
<syntaxhighlight lang="lua">
/c local surface=game.player.surface
for key, entity in pairs(surface.find_entities_filtered({force="enemy"})) do
entity.destroy()
end
</syntaxhighlight>

=== Kill all nearby enemies ===

This will kill all biters, bases and worms in a configurable radius. The default, 250 tiles, is about two zoomed-out screen widths on full HD. After destruction, it shows how many objects were destroyed.

<syntaxhighlight lang="lua">
/c local radius = 250
local surface=game.player.surface
local pp = game.player.position
local cnt = 0
for key, entity in pairs(surface.find_entities_filtered({force="enemy"})) do
if entity.position.x > pp.x - radius and entity.position.x < pp.x + radius
and entity.position.y > pp.y - radius and entity.position.y < pp.y + radius then
cnt = cnt+1
entity.destroy()
end
end
game.player.print(cnt)
</syntaxhighlight>

=== Enable/Disable peaceful mode ===
Enabling peaceful mode prevents biter attacks until provoked. Substitute true for false to disable. Already existing biters are not affected by this command so attacks could continue for a while after activating peaceful mode.
<syntaxhighlight lang="lua">
/c game.player.surface.peaceful_mode = true
</syntaxhighlight>

=== Enable/Disable biter expansion ===
Biter expansion allows biters to create new nests, it is enabled by default. Substitute true for false to disable.
<syntaxhighlight lang="lua">
/c game.map_settings.enemy_expansion.enabled = true
</syntaxhighlight>

== Player character scripts ==
Commands concerning the player directly.
=== Get player position ===
Prints coordinates of your current position.
<syntaxhighlight lang="lua">

=== Teleport player ===
Moves the player to the specified location. You should be able to teleport to a specific player if you obtain their coordinates via them executing the previous command and giving them to you.
<syntaxhighlight lang="lua">
/c game.player.teleport({X, Y})
</syntaxhighlight>

To teleport to the world's origin, use 0,0.

=== Enable god mode ===
God mode removes your player character allowing you to fly over obstacles and take no damage.

Disassociate your controls from the player:
<syntaxhighlight lang="lua">
/c game.player.character=nil
</syntaxhighlight>

Then, hover the mouse over the useless player and destroy it by typing:
<syntaxhighlight lang="lua">
/c game.player.selected.destroy()
</syntaxhighlight>

To undo, spawn a player character. This will spawn a new player at the spawn point of the world, and connect your controls to it.
<syntaxhighlight lang="lua">
/c game.player.create_character()
</syntaxhighlight>

== Research scripts ==

=== Enable faster research ===
<syntaxhighlight lang="lua">
/c game.player.force.laboratory_speed_modifier=1

Tutorial:Nuclear power

2017-08-28T23:49:48Z

Luc: My mistake (I'm correcting my previous edit): each U-235 turns into 10 fuel cells, not one. Modified the sentence to make that clear.

[[Nuclear power]] is a major new feature introduced in version 0.15. It requires higher level technology compared to either solar power or steam boiler power, but it offers very high power output in exchange. It's a great solution for middle- to end-game power generation and it works well in combination with other power generation techniques.

This guide is written for people who want to know exactly how nuclear power works, but don't necessarily want all the solutions. It focuses on what you should do and what you should know to get Nuclear up and running, but doesn't tell you what to do or exactly how to solve the problems.

== First steps ==

:'''Technology required:''' [[Nuclear power (research)|Nuclear power]]
:''You can mine uranium ore sooner, but you'll need the nuclear power technology to do anything useful with it.''

=== [[Uranium ore]] ===
To start, you'll need uranium ore. It glows green, so you can't miss it. It tends to form smaller deposits, though, and you may have to search a while to find a good patch.

Like every other ore in the game, you can mine it with a [[electric mining drill|mining drill]]. Unlike every other ore, however, you'll need to supply [[sulfuric acid]] to the drill. The drills conduct excess acid through themselves, so a row of drills can be supplied by acid from a single side.

:'''Mixed ores:''' If a mining drill covers even a single patch of uranium ore, it will require acid to run at all. The mine will produce mixed ore, as usual.

=== [[Uranium processing|Ore processing]] ===
Once you've got raw uranium ore, you'll need to process it into [[uranium-235]] and [[uranium-238]]. You do this in a centrifuge.

In an un-moduled [[centrifuge]], you can process one ore every 13.3 seconds.

Centrifuges produce a combination of U-235 (the light green stuff) and U-238 (the dark green stuff). Every ten ore processed have a chance to become precisely one of these two products. Out of every 10k ore you process, you can expect to get, on average:

{| class="wikitable" |-
! Count !! Product
|-
| 7 || U-235
|-
| 993 || U-238
|}

That means you can roughly expect to get a single U-235 in one out of every 143 ore. A centrifuge can then be expected to produce U-235 every 1904 seconds. Later on, this won't matter so much. However, when you first start out, this will be an important bottleneck.

:'''Regarding averages:''' Be aware, random is random. These values are ''average'' values. Which means that over the long term, they work out to about these figures. In reality, you'll see long stretches with no U-235 and short stretches with lots of them. Eventually, it won't matter much. But early on, make sure your generation rate is sufficiently high, or you have a sufficient reserve, so you don't find yourself without power when you hit an unlucky stretch.

=== Fuel ===
Before you can burn it in a reactor, you need to create [[uranium fuel cell]]s. You'll probably be using an assembling machine 2, so these will take 13.3 seconds to create as well. Which is fine because fuel cell creation will very rarely be the bottleneck.

You won't want to automatically convert all U-235 into fuel. Only convert what you need to fill your reactor. You're going to want a big fat stockpile of it when you research [[Kovarex enrichment process|kovarex enrichment]] later on.

Each reaction requires 1 U-235, 19 U-238, and 10 iron plate; it produces 10 fuel cells that can be burned in a nuclear reactor.

:'''Tip:''' It isn't a bad idea to use a chest and just stick a pile of iron in it rather than belting the iron in. A full chest of iron probably won't run out before you get bots and replace it with a requester.

Each fuel cell has a nominal energy value of 8 GJ, but it's possible to make them go even farther with reactor neighbor bonuses (more on that later).

=== [[Nuclear reactor]] ===
Once you've got fuel, you'll need to burn it in a nuclear reactor. This is the first step toward turning it into usable energy.

A reactor will produce exactly 40 MW of heat energy. Since a Watt is a Joule per second, this means the reactor will consume one fuel cell every 200 seconds.

Once expended, reactors will produce a "[[used up uranium fuel cell]]", which will need to be cleared. Initially, these will simply accumulate in a chest. Eventually, you can reprocess them into U-238.

:'''Working backward:''' A reactor consumes a fuel cell every 200 seconds and each U-235 gives 10 fuel cells, so every U-235 provides 2000 seconds of reactor power. A centrifuge requires about 1904 seconds to produce a U-235, so you'll need about one processing centrifuges per reactor.

=== [[Heat exchanger]] ===
The heat exchanger takes heat and uses it to convert [[water]] into [[steam]]. It works much like the boiler, but instead of burning fuel, you need to connect it to a heat source. The heat input is marked by a flame when you're placing it.

For simple reactor designs, you can connect it directly to your reactor (which produces heat at points also marked with a flame).

Heat exchangers also require water input, in precisely the way boilers do. They can heat up to 103.09 units/second of water into 500°C steam.

Heat exchangers produce nothing when they are below 500°C. Since they only cool as a consequence of heating water, they will never cool to below that temperature once they've reached it.

Heat exchangers transfer 10 MW of power, so you'll need 4 exchangers to fully consume the power produced by a lone reactor. (Neighbor bonuses can increase this significantly. Again, discussed later.)

==== [[Heat pipe]]s ====
More complex designs will require heat pipes. Heat pipes work much like regular pipes. Like regular pipes, they have limited throughput, which means that shorter pipes are better.

Connect heat pipes point to point, flame to flame, exactly as you would with water pipes. Heat pipes cannot go underground, so if water pipes need to cross them, the water pipe will need to go under. They don't block movement, though, so you can walk right over them.

Throughput on heat pipes is far more limited than regular pipes, in part because there is no analogous "Heat pump". Here are some rough limits on transfer distance:

{| class="wikitable" |-
! Power !! Distance
|-
| 40 MW || ~140
|-
| 80 MW || ~80
|-
| 120 MW || ~55
|-
| 160 MW || ~45
|}

Past these distances, less than 100% of the power will be transferred. This is because at this distance, the maximum reactor temperature of 1000ºC is insufficient to heat the pipe to beyond 500ºC.

:'''Heat pipe storage:''' Heat pipes can store quite a bit of heat as well. A single heat pipe can hold as much energy as a tank with 5.1k steam in it, which makes them even more space efficient than tanks for holding energy (though considerably more expensive). Be cautious, however, with transfer efficiencies. It's very easy to lose more power than you store with an inefficient design.

=== [[Steam turbine]] ===
These are the steam engine's beefy big brother. Using regular fluid pipes, you'll pipe the steam produced by heat exchangers into these turbines.

:'''Perfect matches:''' The steam turbine is a perfect match for the heat exchanger. The steam engine is a perfect match for the boiler. Although it is possible to get energy out of mismatched systems, it's very wasteful and there's no real reason to do it.

Steam turbines consume up to 60 units of steam/second, so you need roughly two steam turbines for every heat exchanger. At large scales, however, you can use fewer turbines, since exchangers only produce 103.09 steam/second. You'll require a separate pump for every 20 turbines.

=== Simplest thing that works ===
At this point, you have all the parts to build your very first reactor:

* A few uranium miners, supplied with sulfuric acid
* 1 Centrifuge, processing uranium ore
* 1 Assembling machine, making uranium fuel cells
* 1 Nuclear reactor
* 4 Heat exchangers, supplied by a single off-shore pump
* 8 Steam turbines

And, of course, assorted, belts, inserters, filter inserters, and other tools for moving things around. This will produce a maximum of 40 MW of power.

== Moving forward ==
Past your simplest reactor, there are some additional nuclear features of which you should be aware.

=== Neighbor bonus ===
This is a critical part of how nuclear designs scale, but it's not complicated. Simply put:

'''Every reactor gets +100% heating power for every active neighboring reactor.'''

Neighbors have to align completely on each side, so reactors will line up in a nice square grid. When they do, the neighbor bonus is activated. You can see the current bonus by hovering over an active reactor.

The bonus to heating power does not increase the fuel consumption. Rather, it simply increases the heat produced!

This, of course, means you'll need more heat exchangers and steam turbines to turn that heat into electricity.

{| class="wikitable" |-
! Configuration !! Reactors !! Exchangers !! Turbines !! Power !! Power per reactor
|-
| Single || 1 || 4 || 7 || 40MW || 40MW
|-
| 2x1 || 2 || 16 || 28 || 160MW || 80MW
|-
| 2x2 || 4 || 48 || 83 || 480MW || 120MW
|-
| 2x3 || 6 || 80 || 138 || 800MW || 133MW
|}

'''How to count heat exchangers:''' Count the number of edges where reactors fully touch. Double that. Add the total number of reactors. Then multiply it all by 4. That's your count of Heat Exchangers. You'll need 1.718 turbines per exchanger (rounded up). Each exchanger will provide up to 10 MW of power.

=== Always on! ===
Unlike every other power generation technique, nuclear reactors '''DO NOT''' scale down power usage. Nuclear reactors will continue consuming one fuel cell every 200 seconds, regardless of the need.

As the reactor consumes its fuel, it heats up to a maximum temperature of 1000°C. At that point, additional fuel burned is simply wasted.

Turbines do scale their production (and steam consumption) to match demand. Likewise, exchangers won't consume heat if there's nowhere to put the steam.

:'''Turbines and engines:''' Be aware that steam turbines and steam engines are both the same "class" of energy producer, so they'll need to be scaled all together. This means that in a complete energy system, your coal boilers may be running when the nuclear plant could fully cover the load. And, worse yet, the nuclear power is just being wasted!
:Consider using accumulators, switches, and circuit logic to disable the coal boilers when nuclear systems can cover the demand.

The simplest solution to this problem is to just run the nuclear reactors part of the time. You can store steam in tanks. (And check out the "fill gauge"; the steam floats!) Since exchanges produce 120 steam/second and a tank holds 25k steam, a tank will keep 208 seconds worth of heat exchanger.

You can put a tank or two at the end of each heat exchanger and use circuit logic to only insert a fuel into the reactors when they get low. Make sure all exchangers are powered at the same time, or you won't get full neighbor bonuses. If you can't keep it from over-fueling, you can also add extra tanks to lengthen the cycle.

=== Enrichment ===
:'''Required technology:''' [[Kovarex enrichment process (research)|Kovarex enrichment process]]
:''Kovarex Enrichment allows you to turn some U-238 into U-235, but it's slow and takes a lot of U-235 as catalyst.''

Your first few patches of uranium ore will last you a reasonable length of time, but eventually you will start running out of ore and places to put extraneous U-238. Enrichment helps solve both problems.

The enrichment process takes about 67 seconds in an un-moduled centrifuge. It requires 40 U-235 (!) and 5 U-238 and makes 41 U-235 and 2 U-238. In effect, it turns 3 U-238 and turns it into 1 U-235; it just requires an extra 40 U-235 and 2 U-238 along for the ride to act as a catalyst.

:'''All the things!:''' Before you ''enrich all the things!'', be aware that you do need 19 U-238 for each fuel cell, as well as requiring it for uranium ammo you will want for storing inside biters and their nests. Circuit logic can help you put a limiter on large-scale enrichment operations.

One Centrifuge enriching uranium is sufficient to supply 29 reactors with fuel, assuming plenty of U-238.

=== Reprocessing fuel ===
:'''Required technology:''' [[Nuclear fuel reprocessing (research)|Nuclear fuel reprocessing]]
:''Reprocessing turns your spent fuel into U-238.''

Eventually, you will run out of places to put spent fuel. You can use reprocessing to turn it back into U-238 to use for enrichment, fuel cells, or ammo. Of the 19 U-238 that go into each 10-pack of fuel cells, this returns 6. This significantly reduces the total ore requirement for nuclear fuel.

=== Weapons ===
:'''Required technology:''' [[Uranium ammo (research)|Uranium ammo]] / [[Atomic bomb (research)|Atomic bomb]]
:''Better bullets / Bigger bombs''

With the Nuclear Age comes nuclear weapons. Uranium ammunition is top-tier, especially when you load a tank with it. It mows down biter nests and clears swarms quite quickly. It uses U-238, so you've probably got plenty of it lying around.

On the other side, you can get [[atomic bomb]]s, which are rockets (shot by a [[rocket launcher]]) that do incredible damage. Be aware, they can easily kill you if you fire them anywhere near you, and even at max range, it's advised that you run in the opposite direction. Rather than a single explosion, they do damage in an expanding ring, giving you time to escape. They require a lot of U-235 and blue chips, so they're an expensive weapon.

Tutorial:Nuclear power

2017-08-28T23:43:16Z

Luc: Sentence didn't make sense logically. I very much doubt the author tested this, and from my experience it can't be right (but I didn't explicitly test it either)

In reality, you'll see long stretches with no U-235 and short stretches with lots of them. Eventually, it won't matter much. But early on, make sure your generation rate is sufficiently high, or you have a sufficient reserve, so you don't find yourself without power when you hit an unlucky stretch.

=== Fuel ===
Before you can burn it in a reactor, you need to create [[uranium fuel cell]]s. You'll probably be using an assembling machine 2, so these will take 13.3 seconds to create as well. Which is fine because fuel cell creation will very rarely be the bottleneck.

You won't want to automatically convert all U-235 into fuel. Only convert what you need to fill your reactor. You're going to want a big fat stockpile of it when you research [[Kovarex enrichment process|kovarex enrichment]] later on.

Each reaction requires 1 U-235, 19 U-238, and 10 iron plate; it produces 10 fuel cells that can be burned in a nuclear reactor.

:'''Tip:''' It isn't a bad idea to use a chest and just stick a pile of iron in it rather than belting the iron in. A full chest of iron probably won't run out before you get bots and replace it with a requester.

Each fuel cell has a nominal energy value of 8 GJ, but it's possible to make them go even farther with reactor neighbor bonuses (more on that later).

=== [[Nuclear reactor]] ===
Once you've got fuel, you'll need to burn it in a nuclear reactor. This is the first step toward turning it into usable energy.

A reactor will produce exactly 40 MW of heat energy. Since a Watt is a Joule per second, this means the reactor will consume one fuel cell every 200 seconds.

Once expended, reactors will produce a "[[used up uranium fuel cell]]", which will need to be cleared. Initially, these will simply accumulate in a chest. Eventually, you can reprocess them into U-238.

:'''Working backward:''' A reactor consumes a fuel cell every 200 seconds, so every U-235 provides 200 seconds of reactor power. A centrifuge requires about 1904 seconds to produce a U-235, so you'll need about ten processing centrifuges per reactor (9.52 centrifuges per reactor, to be exact).

=== [[Heat exchanger]] ===
The heat exchanger takes heat and uses it to convert [[water]] into [[steam]]. It works much like the boiler, but instead of burning fuel, you need to connect it to a heat source. The heat input is marked by a flame when you're placing it.

For simple reactor designs, you can connect it directly to your reactor (which produces heat at points also marked with a flame).

Heat exchangers also require water input, in precisely the way boilers do. They can heat up to 103.09 units/second of water into 500°C steam.

Heat exchangers produce nothing when they are below 500°C. Since they only cool as a consequence of heating water, they will never cool to below that temperature once they've reached it.

Heat exchangers transfer 10 MW of power, so you'll need 4 exchangers to fully consume the power produced by a lone reactor. (Neighbor bonuses can increase this significantly. Again, discussed later.)

==== [[Heat pipe]]s ====
More complex designs will require heat pipes. Heat pipes work much like regular pipes. Like regular pipes, they have limited throughput, which means that shorter pipes are better.

Connect heat pipes point to point, flame to flame, exactly as you would with water pipes. Heat pipes cannot go underground, so if water pipes need to cross them, the water pipe will need to go under. They don't block movement, though, so you can walk right over them.

Throughput on heat pipes is far more limited than regular pipes, in part because there is no analogous "Heat pump". Here are some rough limits on transfer distance:

{| class="wikitable" |-
! Power !! Distance
|-
| 40 MW || ~140
|-
| 80 MW || ~80
|-
| 120 MW || ~55
|-
| 160 MW || ~45
|}

Past these distances, less than 100% of the power will be transferred. This is because at this distance, the maximum reactor temperature of 1000ºC is insufficient to heat the pipe to beyond 500ºC.

:'''Heat pipe storage:''' Heat pipes can store quite a bit of heat as well. A single heat pipe can hold as much energy as a tank with 5.1k steam in it, which makes them even more space efficient than tanks for holding energy (though considerably more expensive). Be cautious, however, with transfer efficiencies. It's very easy to lose more power than you store with an inefficient design.

=== [[Steam turbine]] ===
These are the steam engine's beefy big brother. Using regular fluid pipes, you'll pipe the steam produced by heat exchangers into these turbines.

:'''Perfect matches:''' The steam turbine is a perfect match for the heat exchanger. The steam engine is a perfect match for the boiler. Although it is possible to get energy out of mismatched systems, it's very wasteful and there's no real reason to do it.

Steam turbines consume up to 60 units of steam/second, so you need roughly two steam turbines for every heat exchanger. At large scales, however, you can use fewer turbines, since exchangers only produce 103.09 steam/second. You'll require a separate pump for every 20 turbines.

=== Simplest thing that works ===
At this point, you have all the parts to build your very first reactor:

* A few uranium miners, supplied with sulfuric acid
* 1 Centrifuge, processing uranium ore
* 1 Assembling machine, making uranium fuel cells
* 1 Nuclear reactor
* 4 Heat exchangers, supplied by a single off-shore pump
* 8 Steam turbines

And, of course, assorted, belts, inserters, filter inserters, and other tools for moving things around. This will produce a maximum of 40 MW of power.

== Moving forward ==
Past your simplest reactor, there are some additional nuclear features of which you should be aware.

=== Neighbor bonus ===
This is a critical part of how nuclear designs scale, but it's not complicated. Simply put:

'''Every reactor gets +100% heating power for every active neighboring reactor.'''

Neighbors have to align completely on each side, so reactors will line up in a nice square grid. When they do, the neighbor bonus is activated. You can see the current bonus by hovering over an active reactor.

The bonus to heating power does not increase the fuel consumption. Rather, it simply increases the heat produced!

This, of course, means you'll need more heat exchangers and steam turbines to turn that heat into electricity.

{| class="wikitable" |-
! Configuration !! Reactors !! Exchangers !! Turbines !! Power !! Power per reactor
|-
| Single || 1 || 4 || 7 || 40MW || 40MW
|-
| 2x1 || 2 || 16 || 28 || 160MW || 80MW
|-
| 2x2 || 4 || 48 || 83 || 480MW || 120MW
|-
| 2x3 || 6 || 80 || 138 || 800MW || 133MW
|}

'''How to count heat exchangers:''' Count the number of edges where reactors fully touch. Double that. Add the total number of reactors. Then multiply it all by 4. That's your count of Heat Exchangers. You'll need 1.718 turbines per exchanger (rounded up). Each exchanger will provide up to 10 MW of power.

=== Always on! ===
Unlike every other power generation technique, nuclear reactors '''DO NOT''' scale down power usage. Nuclear reactors will continue consuming one fuel cell every 200 seconds, regardless of the need.

As the reactor consumes its fuel, it heats up to a maximum temperature of 1000°C. At that point, additional fuel burned is simply wasted.

Turbines do scale their production (and steam consumption) to match demand. Likewise, exchangers won't consume heat if there's nowhere to put the steam.

:'''Turbines and engines:''' Be aware that steam turbines and steam engines are both the same "class" of energy producer, so they'll need to be scaled all together. This means that in a complete energy system, your coal boilers may be running when the nuclear plant could fully cover the load. And, worse yet, the nuclear power is just being wasted!
:Consider using accumulators, switches, and circuit logic to disable the coal boilers when nuclear systems can cover the demand.

The simplest solution to this problem is to just run the nuclear reactors part of the time. You can store steam in tanks. (And check out the "fill gauge"; the steam floats!) Since exchanges produce 120 steam/second and a tank holds 25k steam, a tank will keep 208 seconds worth of heat exchanger.

You can put a tank or two at the end of each heat exchanger and use circuit logic to only insert a fuel into the reactors when they get low. Make sure all exchangers are powered at the same time, or you won't get full neighbor bonuses. If you can't keep it from over-fueling, you can also add extra tanks to lengthen the cycle.

=== Enrichment ===
:'''Required technology:''' [[Kovarex enrichment process (research)|Kovarex enrichment process]]
:''Kovarex Enrichment allows you to turn some U-238 into U-235, but it's slow and takes a lot of U-235 as catalyst.''

Your first few patches of uranium ore will last you a reasonable length of time, but eventually you will start running out of ore and places to put extraneous U-238. Enrichment helps solve both problems.

The enrichment process takes about 67 seconds in an un-moduled centrifuge. It requires 40 U-235 (!) and 5 U-238 and makes 41 U-235 and 2 U-238. In effect, it turns 3 U-238 and turns it into 1 U-235; it just requires an extra 40 U-235 and 2 U-238 along for the ride to act as a catalyst.

:'''All the things!:''' Before you ''enrich all the things!'', be aware that you do need 19 U-238 for each fuel cell, as well as requiring it for uranium ammo you will want for storing inside biters and their nests. Circuit logic can help you put a limiter on large-scale enrichment operations.

One Centrifuge enriching uranium is sufficient to supply 29 reactors with fuel, assuming plenty of U-238.

=== Reprocessing fuel ===
:'''Required technology:''' [[Nuclear fuel reprocessing (research)|Nuclear fuel reprocessing]]
:''Reprocessing turns your spent fuel into U-238.''

Eventually, you will run out of places to put spent fuel. You can use reprocessing to turn it back into U-238 to use for enrichment, fuel cells, or ammo. Of the 19 U-238 that go into each 10-pack of fuel cells, this returns 6. This significantly reduces the total ore requirement for nuclear fuel.

=== Weapons ===
:'''Required technology:''' [[Uranium ammo (research)|Uranium ammo]] / [[Atomic bomb (research)|Atomic bomb]]
:''Better bullets / Bigger bombs''

With the Nuclear Age comes nuclear weapons. Uranium ammunition is top-tier, especially when you load a tank with it. It mows down biter nests and clears swarms quite quickly. It uses U-238, so you've probably got plenty of it lying around.

On the other side, you can get [[atomic bomb]]s, which are rockets (shot by a [[rocket launcher]]) that do incredible damage. Be aware, they can easily kill you if you fire them anywhere near you, and even at max range, it's advised that you run in the opposite direction. Rather than a single explosion, they do damage in an expanding ring, giving you time to escape. They require a lot of U-235 and blue chips, so they're an expensive weapon.

Railway

2017-06-04T16:46:45Z

Luc: Expanded troubleshooting No Path issue (this took me 1.5 hours...)

{{Languages}}

:''For the research see [[Railway (research)]]''

The Railway is one of the main transport methods in Factorio. Although the installation of such a network can be complicated, and requires a large amount of resource and space, it is faster and more efficient than [[Belt transport system|belts]] and [[Logistic network|robot logistics]], especially over large distances.

Railway construction, however, is not understood instantly. It takes some time to learn the basics, such as automating transportation. Learning how to manage and maintain upkeep of a larger train network takes time and experience.

== Infrastructure ==

To build a railway, tracks (also called rails) must be built for the train to ride on. Typically, this is done via the [[Rail planner]], but can also be done manually. Bear in mind that rails can rails are placed on a two-tile grid, so you cannot move a rail by only one tile.

=== Minimum manually operated railway ===
As a minimum a manually operated railway has to consist of:
* [[Rail]]s (tracks)
* [[Locomotive]]s

Locomotives can be entered and then manually operated by standing next to them and pressing the {{Key|RETURN}} button.

=== Switches ===
* There is no visual representation of a working switch, however the rails will appear to merge. Using the rail planner, the player must place a [[rail]] overlapping an existing rail to form a switch. Switches are forks in tracks that allow a train to pick between two directional options.
* The crossing of two straight tracks is not usable as switch, as trains have a limited turning radius. They do, however, connect [[Rail signal| signal blocks]] which helps prevent collisions.
* Parallel tracks do not interact with each other and generally have no problems. However, switching from one track to the other can require extra resources if they are too close together; the track must turn away from the other parallel track and then turn back to it. This can create complicated networks of signals and, as such, one should generally not build parallel tracks unless they are spaced adequately. (Generally, 2 track widths apart works well)

=== Crossing tracks ===

[[File:fff-140-controlled-gates.gif|thumb|An example of a safe railway crossing.]]

'''Be careful when crossing tracks! Trains are one of the highest damaging entities in the game, and will kill most players instantly on contact.'''

A checklist of proper track crossing etiquette:

# Zoom out, so that you can see a train coming.
# Look left, then right.
# Check for signals nearby: If a [[rail signal]] suddenly jumps from green to red or green to yellow, a train is coming. Do not cross.
# Avoid walking near the tracks, as you do not need to be fully on the tracks to get hit.
# While it is possible to get into/out of a train while it is moving, a miss can cost your life. The sides of the train can still deal damage, as well as the player being able to slip between two rail cars.
# Heavy [[Energy shield|shields]] can be used to reduce the damage taken. In extreme cases, it is possible to stop a train with your body. This will require several shield modules to not be instantly killed, and will drain a large amount of the suit's energy.
# All entities with health will take damage getting hit by a train, so take care not to leave a [[Car]] or [[Tank]] on the tracks. However, this includes hostile forces!
# Trains far from a [[train stop]] will be traveling at (near) max speed, so take extra precaution when crossing and zoom out further. Trains near a [[train stop]] or signal will slow down to stop, and will be traveling slower. Trains of different configurations will also move slower or faster.

A safe railroad crossing like the example shown in the picture can be built. This works by restricting access to the tracks when an oncoming train has the rails reserved. When the player is on the rails, the signals are reserved by the [[circuit network]], and the train must stop and wait until the player leaves the tracks. When a player is inside the area crossing the tracks, the train gates are closed so the player can't get on the tracks outside the crossing. This is to completely ensure a safe crossing, and is often used on servers.

== Trains ==

Train components:

|}

[[File:Railway-assemble-train.png|thumb|left|300px|Placing a [[Cargo wagon]] so it is attached to the train.]]

* A train consists of at least one locomotive.
* Trains can have more than one locomotive, and any number of [[Wagon]]s.
* Locomotives can be '''manually''' driven forwards or backwards, however, they are generally slower going backwards. The left and right movement keys are used to change direction at switches.
* Trains can only drive forwards automatically. An automatic train can drive forwards and backwards when two locomotives facing different directions are connected to the train.
* A train needs [[fuel]] to drive. Despite being called Diesel Locomotives, they will take anything with a fuel value. Fuel can be added by inserters.
* A common way to refuel trains is using a [[requester chest]] that requests [[fuel]], and then having a [[burner inserter]] loading the fuel into the locomotive.

The locomotives' inventory is only used for [[Fuel]]. To transport items [[Cargo wagon]]s have to be attached to the train. To attach a Cargo wagon, the player may either prepare to place one near an existing train, where a green graphic will show the player that the cargo wagon will be attached, showing a connection between the train and the new wagon. Alternatively, the player may manually connect cargo wagons to trains with the stock connect key, if the cargo wagon was placed far away from a train. The cargo wagons can be filled manually or by adjacent [[Inserters]].

* [[Railway/Train path finding]] - How trains find their path.

== Stations ==

Station Components

{| class="wikitable"
|{{imagelink|train-stop|Train stop}} || {{imagelink|straight-rail|Rail|Rails}} || {{imagelink|Inserter-icon|Inserters}}|}

[[File:station-example-1.png|thumb|right|256px|A very minimal train station.]]
[[File:station-example-2.png|thumb|400px|High-performance train station for short trains. Highest possible unload rate, waiting spots, refueling, defended, multi-train capable, modular, extend-able.]]
A '''train station''' is a combination of at least one [[train stop]] plus a [[storage]] and/or distribution system, used to fill or empty [[Cargo wagon]]s, load [[fuel]] into the [[Diesel Locomotive|locomotive(s)]], or repair trains.

'''Don't mix up ''train stations'' with ''train stops''.''' A train station is a concept, whereas a [[train stop]] is an item.

[[Inserter]]s placed next to train tracks are used to load/unload trains at train stops. Inserters are the only way to get items off and onto cargo wagons.

{{clear}}

== Signals ==
The two types of signals in Factorio:
{| class="wikitable"
| {{imagelink|rail-signal|Rail signal}} || {{imagelink|rail-chain-signal|Rail chain signal}} |-
|}

Understanding rail signals can be difficult. Several terms critical to understanding them are below:
*Rail segment
: A piece of track (one item).
*Segment
: A single path of continuous track without intersections or switches. This becomes important when signals are employed. The player may mouse over a segment to see its number. It's number is unique within the world, however does not start from 0 or 1.
*Block
: A set of segments defined by rail signals. By default every connected segment belongs to one block, no matter whether a train can drive on it or not, and even if it can be driven only in one direction (e.g. at a switch, both segments of the switch belong to the same block). The player can see the current block numbers of a rail piece in the info section on mouse-over.

Rail signals are used to employ multiple trains automatically. Note that driving a train manually ignores most of the rules described here; other automatic trains will follow signaling indicted by the player's movement dynamically, however it will sometimes be not possible to avoid a collision for automatic trains if the player ignores red/yellow signals. Always beware automatic trains and give them the right of way.

'''See [https://forums.factorio.com/viewtopic.php?f=18&t=3811#p28310 this forum post]''' for a good explanation about blocks.

=== Basic Signaling Rules ===
* There is at most one Train in a block at any time. A train spanning multiple blocks occupies them all.
* A red signal means that the following block is occupied by a train.
* A yellow signal means that a train is approaching and already has the approval to enter the following block.
* [[Rail signal]]s separate a new block and reflect its state: green - free, yellow - reserved, red - occupied, blue - one of the paths is blocked
* [[Rail chain signal]]s separate a new block and reflect the state of the next [[Rail signal]]
* A train can only pass a signal on the right of the track, or if there is a signal on both sides on the same rail segment. Of course, manual driving overrides this.

{{clear}}

== Deadlocks ==

A deadlock or gridlock can happen when every train is locked by another. In nearly every case two or more trains are standing so that every train blocks (by minimum) one other train.

=== Deadlock occurrence ===

Deadlocks occur when two+ trains are prevented from continuing through an intersection, due to an unsolvable signal conflict. There are a few different types of deadlocks:

# Temporary - These are caused by a Temporary hiccup in a train's path, such as a loading train being in the way, or created by closing a signal with the [[circuit network]]. These often resolve themselves.
# Semi-Permanent - These are the result of a problem with pathing, often created by a fuel-less train or broken rail, and may require player interaction in order to free.
# Permanent - This type is the worst, and cannot be resolved automatically, often requiring the player to manually drive several trains to get them out of the intersection. These often are caused by incorrect signal placement or unreachable stations.

It's important to remember that deadlocks can happen by chance, and by mistake of the player. Sometimes even perfectly signaled rails have issues. The rate of deadlocks is inversely proportional to the quality of Signaling, however.

=== Factors that influence the deadlock chance ===

* Train length (shorter trains will have a lower chance with the same rail/signal layout, due to having less effect on the rails they're on.)
* Size of the blocks: More space for the blocks means lower chance of deadlock.
* Track layout: Some layouts have a higher chance of locking, than others.
* Quantity of trains - More trains trying to use an intersection will result in higher chance of deadlock.
* The chance is also much higher if trains need to wait often in areas with rail-crossings.

Knowing the factors, how can deadlocks be reduced?

* Don't use 4-way junctions or roundabouts (circles) to create junctions.
* Use better 3-way junctions. See [http://www.factorioforums.com/forum/viewtopic.php?f=18&t=9044 A Detailed Look at a Bidirectional Three-way Train Intersection]
* Use roundabouts only for changing direction of train, and never for high traffic intersections.
* Build more tracks around junctions. Don't have one junction be the only way to reach a place, add redundancy. This keeps a small problem a small problem.

== Automated transport ==
[[File:train-schedule-gui.png|thumb|300px|The new train GUI since 0.13 (schedule tab): 1 - switch between automatic and manual driving mode; 2 - add new train stop; 3 - delete selected train stop; 4 - send train to selected train stop; 5 - add wait condition for selected train stop; 6 - delete selected wait condition; 7 - change logical mode of selected wait condition]]

This section covers items used to make trains automatically transport items between stations. The player should be familiar with creating a rail system.

First, the player has to setup a rail system with at least two train stops, which are placed in the right-hand side of the expected train arrival direction. By hovering over the train stop with the mouse you see the positions of the vehicles for better setting up the train station (including (un)loading machinery, refueling/repair installations).

When you set up the train schedule (see below) and fuel the train, you can start the train on it's schedule by switching from manual to automatic driving mode.

=== Train schedule ===

The player can set up a list of train stops in the upper window. The train will run to the stops in the given order, if it's at the end it will continue with the first. Currently, it's not possible to make a one-time schedule. Stops can be added by clicking button 2 (see picture). A pop-up appears with a list of all train stops. If you select one, another pop-up appears where you have to select a wait condition.

Wait conditions are used to tell the train when to leave the station. There are 6 types of wait conditions:
* '''Time passed''' - the only one available until version 0.12.
* '''Inventory full''' - All inventories of the train are full.
* '''Inventory empty''' - Same as above, but empty.
* '''Item count''' - The train (all cargoes summed) contains a specific amount of a certain item.
* '''Circuit condition''' - The train stop is connectable to the [[Circuit network]], so the signals can used for wait conditions.
* '''Inactivity''' - No items were added or removed for the specified amount of seconds.

Hereafter the word "term" is used to describe ''one'' type of wait condition, and the words "wait condition" are used to describe the whole set of terms (it turns a bit into maths).

If you add more than one term, you can change the connection of those using the logical operators AND and OR (button 7). An AND condition will result in true if all terms are true. An OR condition will return true if at least one of the terms is true.

When mixing AND and OR terms, the logic is grouped by the OR terms. When evaluating the wait condition, the first term is evaluated along with all AND terms immediately following up to but excluding the next occurring OR term. If they all evaluate true, the wait condition evaluates true. Otherwise, evaluation continues with that next occurring OR term and all AND terms immediately following it, up to the next OR term. This continues until either an OR group evaluates true and the wait condition is satisfied, or all terms have been checked.

==== Examples ====

<div class="toccolours mw-collapsible mw-collapsed" style="width:800px">
Expand for examples
<div class="mw-collapsible-content">
Wait until full, up to 30 seconds:

<pre>
Full cargo inventory
OR 30 seconds passed
</pre>

Wait until cargo full, ''or'' circuit condition Oil > 3000:

<pre>
Full cargo inventory
OR Circuit condition - Oil > 3000
</pre>

Wait until empty, ''and'' 30 seconds passed, ''and'' 5 seconds of inactivity:

<pre>
Empty cargo inventory

Wait until iron ore is low, ''or'' copper ore is low ''and'' at least 30 seconds passed:

<pre>
Cargo: Iron ore < 500
AND 30 seconds passed
OR Cargo: Copper ore < 500
AND 30 seconds passed
</pre>

Factorio's wait condition logic is read as disjunctive normal form ([https://en.wikipedia.org/wiki/Disjunctive_normal_form DNF]), and so this last example is processed as (note the parenthesis):

<pre>((Cargo: Iron ore < 500 AND 30 seconds passed) OR (Cargo: Copper ore < 500 AND 30 seconds passed))</pre>

Which is the same as this:

<pre>((Cargo: Iron ore < 500 OR Cargo: Copper ore < 500) AND 30 seconds passed)</pre>

Unfortunately, there is '''no''' way to write that shorter form in the current UI.
</div></div>

=== Troubleshooting ===

Below are some things to verify if a rail system or train is not working.

* Is the train fueled? Ensure that the locomotive has [[fuel]] of some kind.
* Misplaced or non-functional switches? Ensure that the train can plan a path through the switches.
* Another train on the same [[Railway#Segment|segment]] or [[Railway#Block|block]]? Make sure the path of the train is unobstructed.
* Train stops placed correctly? Make sure that the yellow arrows when hovering on the stop point towards the end or exit of the stop.
* Is the train allowed to enter signals from the right direction? Are the signals set correctly?
* If a track is supposed to be two-way, the rail signals should be opposite each other. You can verify they match up by hovering the cursor over one. For a matched pair, it will show the other.

==== No path ====
When trains cannot reach the target, a "no path" symbol pops up over the locomotive. Check:
* Can the train reach it's current destination by '''only driving forward'''? Build turning slopes or place a locomotive at both ends of a train!
* Are the train stops standing in the right direction? Train stops must be on the right hand side of the track.
* If you use rail signals, check that the signals are all allowing traffic in the correct direction.''
* Check for interruptions in the train tracks, drive to the station manually to check there are no rail parts missing. Especially near junctions these can be hard to spot if missing.

If you are still having problems, consider:
* Driving the train manually, and as you pass each switch, try switching to automatic. When it works, you will know the rough area of the problem.
[http://imgur.com/a/Nq2Yk A pictorial summary of typical problems].

A vague issue exists (at least in 0.15.9) where the following steps helped:
* Remove the unreachable stop from the train schedule
* Re-create (mine and place) the unreachable train stop
* Add the train stop back in the schedule.

No bug report was created because the issue was non-reproducible.

Tutorial:Applied power math

2017-04-01T18:17:59Z

Luc: Added Category:Tutorial

In this tutorial we'll be answering the question: '''how much coal is needed to power a factory?'''

First off, we need to know: how much power does our factory use? That's easy - you can check the electricity tab by clicking on a power pole.

[[File:power-details.png|800px]]

Here we see one radar using 300kW (the 299kW is a rounding error). Factorio uses real science here. A Watt (W) is a measure of energy transfer. A kilowatt (kW) is 1000 W, a megawatt (MW) is 1000 kW, and if you're lucky enough to ever make a factory big enough, a gigawatt (GW) is 1000 MW.

So that answers the question of how much power our factory uses. To keep our factory running at full speed we need to maintain 300 kW. For ease of comparison, we'll convert that to 0.3 MW.

Next question! How much power is stored in coal? That's also easy, because it tells us when we hover over it: 8 MJ.

[[File:coal-joules.png|300px]]

A Joule is another standard measure of stored energy. As with Watts a kilojoule (kJ) is 1000 J, and so on. There is a fixed relationship between Joules and Watts. '''1 Joule can provide 1 Watt of energy for 1 second.''' As a formula:

J = W × s

So to run our factory at 0.3 MW, we need to consume 0.3 MJ every second.

== Quiz ==

Assuming perfect efficiency, how long could one piece of coal (8 MJ) run
our single radar (0.3 MW)?

<div class="toccolours mw-collapsible mw-collapsed">
'''Expand to reveal answer'''
<div class="mw-collapsible-content">
8 MJ = 0.3 MW * s
s = 8 MJ / 0.3 MW
s = 26.67

Nearly 27 seconds.

Assuming perfect efficiency, what is the maximum size factory (in watts)
a single piece of coal could run for 5 seconds?

<div class="toccolours mw-collapsible mw-collapsed">
'''Expand to reveal answer'''
<div class="mw-collapsible-content">
8 MJ = MW * 5
MW = 8 MJ / 5
MW = 1.6

1.6 megawatts.
</div>
</div>

'''BONUS!''' A ton of real world coal [http://hypertextbook.com/facts/2006/LunChen.shtml|contains about 21 GJ]. How much does a
piece of Factorio coal weigh?

<div class="toccolours mw-collapsible mw-collapsed">
'''Expand to reveal answer'''
<div class="mw-collapsible-content">
The energy ratios will match the weight ratios, so:

8 MJ / 21000 MJ = weight / 1000 kG
weight = (8 MJ / 21000 MJ) * 1000 kG
weight = 0.38 kG

About 400g! Still doesn't explain how our character can carry so much of it...
</div>
</div>

== Efficiency ==

Let's test it! We should be able to run a radar for 27 seconds, right? Using a setup with a single boiler, steam engine, and radar, we can drop a single piece of coal in the boiler and see how long the radar runs.

[[File:radar-example.png|800px]]

We barely got 20s! What's wrong? We are generating less power than expected.
Let's measure using an accumulator.

[[File:Accumulator-example.png|800px]]

We started with 8 MJ in the coal, but only 4 MJ ended up in the accumulator.
This is because, like in the real world, some energy is lost along the way as
waste. In this case, only 50% is making it into our accumulator. In Factorio,
this loss happens in the boiler, and it actually tells us this in the item details! You can think of the waste 50% as going into the pollution it generates...

[[File:boiler-details.png]]

Now we have everything we need to answer our initial question: '''how much coal do we need to power our factory?''' Well, the question actually needs to be a bit
more precise: how much coal do we need ''per second'' to power our factory?

<div class="toccolours mw-collapsible mw-collapsed">
'''Aside: why did the radar run for 20s and not 13.5s (50% of 27s)?'''
<div class="mw-collapsible-content">
Because it doesn't turn on and off instantly. As you can see in the graph, it ramps up then ramps down. Technically, if you measured the area under the curve it would give you the expected 4 MJ.

== Quiz ==

How much coal per second is needed to power a 20 MW factory?

<div class="toccolours mw-collapsible mw-collapsed">
'''Expand to reveal answer'''
<div class="mw-collapsible-content">
Since <code>J = W × s</code>, a 20 MW factory will consume 20 MJ/s. We'll need 40 MJ/s input due to the 50% boiler efficiency loss. Since coal contains 8 MJ, we'll need '''5 coal per second''' (<code>5 × 8 MJ = 40 MJ</code>).

</div>

'''SECOND BONUS!''' The average American household uses [https://www.eia.gov/tools/faqs/faq.php?id=97&t=3|3.2 GJ in a month] (typically expressed as ''888 kilowatt hours''). How much Factorio coal would be needed to power one of these homes for that period, and how many homes could a steam engine support ([[Steam_engine|510 kW]]), assuming the power is used at a constant rate? (Assume 30 days in a month.)

<div class="toccolours mw-collapsible mw-collapsed">
'''Expand to reveal answer'''
<div class="mw-collapsible-content">

3.2 GJ = 3,200 MJ
3200 MJ / (8 MJ * 50%) = 800

3200 MJ / 30 days / 24 hours / 60 minutes / 60 seconds = 1,235 W
510,000 / 1235 = 412

800 pieces of coal per household, and a single steam engine could power 412 households.

Steam engine

2016-10-09T09:56:35Z

Luc: This was incorrect, probably a rounding error.

{{Languages}}
{{:Steam engine/infobox}}

Steam engines are used to produce electricity. They do this by taking in hot water and converting it into electricity. The hotter the water the more electricity can be produced. If there is an overabundance of electricity then steam engines will reduce their production to match consumption.

Hovering the mouse over a steam engine will display information for that particular steam engine: current production as well as maximum productivity.

It is possible to chain multiple steam engines together as water will pass through them. The current optimal ratio is 1 [[offshore pump]] : 14 [[boiler]]s : 10 [[steam engine]]s.

'''Steam engines themselves don't produce any pollution.''' ([[Boiler]]s do!)

== Using other liquids ==

The steam engine can use any type of liquid to generate electricity. This can be used to get rid of unused oil-products. Just fill unusable oil products into a steam engine and it will destroy the liquids (cold liquids will be destroyed at a rate of [https://forums.factorio.com/viewtopic.php?p=144748#p144748 6.0 fluid / second]). It works the same as for cold water; you don't need to warm it. If you heat the liquid before that, the hot oil will produce electrical power, just like with hot water.

By default, water is 15°C and oils are 25°C. The steam engine happens to work with water from 15°C and oils from above 25°C (a complete coincidence). An oil temperature of 25.22°C will get you about 1.3KW of power. Heating up water or oils makes no difference: heating one liter of water from 15 to 16 degrees takes just as much energy as heating one liter of oil from 25 to 26 degrees[http://because.a.tweet.doesnt.fit.lucb1e.com/?text=1.4k+water+15%B0C-%3E17.73%B0C+and+1.4k+light+oil+25%B0C-%3E27.82%B0C%2C+both+using+1+coal+in+a+boiler%2C+filling+an+empty+tank+from+a+full+tank+until+the+coal+boiler+runs+out.+I+stopped+a+bit+early+on+the+water+one+and+the+difference+seems+negligible. (OC)]. It was not tested how much energy the steam engine produces with 16°C water versus 26°C oil, but it probably does not warrant using oils instead of water.

In general you should convert the unusable oil products into useables, instead of just making electricity out of it!

Fluid system

2016-10-09T09:44:41Z

Luc: Mentioned that oils cannot be dumped in a lake either (next to "cannot be dropped on the ground"). I tried this with byproducts once.

{{Languages}}
'''Liquids''' <small>(''[[Liquids#Notes|note]]'')</small> are non-solid [[items]] like water and oil.

==Behavior==
Liquids can only exist inside [[pipe]]s and certain buildings, meaning they cannot be carried by the player, moved using [[inserters]], dropped on the ground, or even dumped in a lake. They are counted in continuous fractions, rather than discrete integers. Liquids can be silently destroyed by removing buildings or pipes, mixing types of liquid, or at the output of a [[steam engine]].

=== Pressure and throughput ===

Liquid will move in pipes from high pressure to low pressure. The pressure of a liquid in a pipe can be seen through the pipe window. A pipe with high pressure will show itself nearly full, a pipe with low pressure will show a small trickle of the liquid.

==Flow mechanics==

Mods

2016-10-04T01:26:47Z

Luc: The "as of 0.14.7" made it sound like it's new since that version. Since it's the current state of (sad) affairs and it has always been this way, no need to mention a version.

{{languages}}

A mod (short for modification) is an alteration of the game. Modifications can range from small tweaks to total conversions.

==Finding mods==
Starting in Factorio version 0.13, mods are available from within the game via the Mods option on the main menu. Here you'll find all mods published to the official Factorio mod database. If you want more information on a mod, visit its page at [https://mods.factorio.com/ mods.factorio.com].

Other mod listings exist as well, most importantly [http://factoriomods.net/ factoriomods.net] and [https://forums.factorio.com/viewforum.php?f=194 the forums]. Although mods you find there must be manually installed, that's pretty easy—see "Manual installation" below for how.

==Manual installation==
Installing a downloaded mod is very easy:
# Find mod you like. It must support the version of Factorio that you have installed.
# Download the mod. This will normally come as a ZIP file. Do not unzip it.
# Copy the ZIP into the appropriate directory. For Windows that's <code>%appdata%\Roaming\Factorio\mods</code>, and for Linux it's <code>~/.factorio/mods</code>. If the directory doesn't exist, create it.
# Launch Factorio. New mods are enabled by default, so you can start using the mod immediately.

Xterminator has made a [https://youtu.be/SEOedyrFQ_g video tutorial for that] (Windows only).

==Gotchas about using mods==
* Some mods only work properly with maps created ''after'' the mod is installed. Typically the mod description will warn you about that.
* If you install a mod that prevents Factorio from launching, you can simply delete the mod from the mods folder. See "Manual installation" for the location.
** Note: You may want to check whether there's already a newer version of the mod that fixes the problem. Even high-quality mods can break as Factorio changes.
* Some mods require other mods as dependencies. Factorio does ''not'' automatically pull in dependencies. The mod description will normally tell you if there are any.

Multiplayer

2016-10-04T01:15:27Z

Luc: Updated old URL

{{Languages}}

Factorio supports multiplayer games in additional to the single-player campaign and scenarios. By default, multiplayer games run the CO-OP [[Game modes and options|freeplay scenario]] where all players work together to launch a rocket with a satellite into space. Other scenarios, including PvP maps, are available for download from the [https://forums.factorio.com/viewforum.php?f=36&sid=93d1fbe9336d31d6bac60847b6c97985 Maps and Scenarios forum].

Currently, joining a multiplayer game requires either that all players be on the same LAN or that the host have a public IP address. The next version of Factorio, 0.13, will support a public multiplayer game lobby for locating games as well as [https://www.factorio.com/blog/post/fff-76 NAT punching] to make connecting to a server without a public IP address more seamless.

== History ==

Because of the potentially immense amount of activity on a map, the game engine utilizes a [https://www.factorio.com/blog/post/fff-76 lock step architecture]. All instances of the game run full simulations of the entire world and only player actions are transferred across the network.

Multiplayer games were introduced to Factorio with version 0.11.0. The only connection method available was peer-to-peer mode which meant every player had to be able to directly communicate with every other player. In version 0.12.4, a client-server mode of communication was introduced in which the server (either a dedicated one or the player who hosted the game) relays messages to all peers. This means that direct connection between all players is no longer necessary. The client-server mode will be the only available in 0.13.

As of version 0.12.0, the game features "latency hiding" mechanics where the game simulates some of the player's actions locally to make some common interactions (such as moving the player's character) more fluid. Latency hiding is enabled by default, but it can be enabled or disabled in Options → Other → Enable multiplayer latency hiding. Not every action is a part of latency hiding – most notably, car or train driving and shooting are not a part of it.

== Setting Up a Multiplayer Game ==

Use the ''Multiplayer'' button in the game menu to start a multiplayer game. One player starts the game and acts as the host. That player should provide the other players with his or her IP address. They can then use that IP address to join the host's game.

Other notes and tips:

* All game instances need the installation of exactly the same game-versions and mods.
* Factorio uses the port '''34197'''. The port can be changed in the [[Application Directory|config]] file.
* Factorio uses '''UDP only'''. Make sure you configure your router's port forwarding correctly. (The game builds it's own "reliable delivery" layer built on UDP to deal with packet loss and reordering issues.)
** Make sure there is no firewall or anti-virus blocking the UDP-packets.
* See the [[#Connecting to a Server Behind NAT|section below]] for help configuring your networking set up.
* The hard limit for the number of players is [https://forums.factorio.com/viewtopic.php?f=53&t=6481&p=50661#p50586 65535]. :)

=== Voice Chat ===
* It is recommended that players use voice chat (TeamSpeak, Skype) because you need to talk a lot to coordinate connections, building, handling attacks, etc. TeamSpeak servers are posted in the [https://forums.factorio.com/viewforum.php?f=53 multiplayer forum].

=== Finding Other Players ===

* Use the [https://forums.factorio.com/viewforum.php?f=53 multiplayer board in the forum].
* Many players use other software like Evolve to meet other players. This also has the "advantage" of creating a virtual LAN among the players. See down under software.
* Some also use [https://forums.factorio.com/viewtopic.php?f=5&t=9136 Steam] to find other players.
* There is an external [http://serverlist.lgms.nl/ server browser] with various search options.
* Tell your friends to buy Factorio, then play with them!

=== Connecting to a Server Behind NAT ===

Factorio requires that the server (in client-server mode) or all peers (in peer-to-peer mode) have a publicly accessible IP address or that all players are on the same LAN. If you are behind NAT, you must set up port forwarding ([[Multiplayer#Playing_over_LAN_.2F_Internet|see above]] for port number) or use virtual LAN software such as Hamachi or Evolve.

By default, multiplayer games will be launched in client-server mode (also [http://www.factorio.com/blog/post/fff-99 multiplayer forwarding] mode). In this mode, all clients send their network traffic to the server and the server forwards the traffic to the other clients. The advantage of this is that it allows games where some players are inside a LAN and others are outside. The disadvantage may be slightly more lag as packets must travel an extra hop (through the server). Multiplayer games may be launched in peer-to-peer mode to disable this forwarding behavior by checking the ''Use peer-to-peer communication'' box when starting the game as the host. Using peer-to-peer is no longer recommended and will be removed entirely in 0.13.

== Game Types ==

=== Co-op ===

In co-op mode, all players are on the same force which means all players share the same research progression, any player can access items stored in a container built by any other player, and defensive structures built by any player will not target any other player.

To start a co-op game:

# Launch Factorio
# Click ''Play''
# Click ''Multiplayer''
# Click ''New game''
# Select map generator options, then click ''Generate''
# Choose latency and other settings, then click ''Play''
# Other players can now join the game

=== PvP ===

In PvP mode, players can be on different forces. Each force can have one (free-for-all) or more players (teams). Each force has its own independent research progression. Additionally, each force's [[Turret|turrets]] and [[Combat Robot Capsules|combat bots]] will attack other players as enemies, unless a cease fire is set. Note that, depending on the scenario, cease fires may be unidirectional — setting a cease fire with an opposing force does not guarantee a cease fire from them in return.

To start a PvP game, you must have a PvP-compatible scenario downloaded (or use the console commands to manually assign players to different forces, [[#Forces|see below]]). PvP scenarios can be found in the [https://forums.factorio.com/viewforum.php?f=36&sid=93d1fbe9336d31d6bac60847b6c97985 Maps and Scenarios forum].

'''Example PvP scenarios:'''

* [https://forums.factorio.com/viewtopic.php?f=36&t=15052 Various scenarios by Klonan]

After downloading a PvP scenario, you need to start the scenario as a single player custom scenario, save it, then load it as a multiplayer game. Otherwise, Factorio will launch the default freeplay scenario in co-op mode. In detail:

# Download the scenario and place the scenario directory in the ''scenarios'' directory within your [[Application_directory#Directory_locations_by_OS_and_installation_method|user data directory]].
# Launch Factorio
# Click ''Play''
# Click ''Custom scenario''
# Choose the PvP scenario you want under ''User scenarios'' and click ''Create''
# (Depending on the scenario, you may need to set the map generation settings and click ''Generate'')
# Hit Escape and click ''Save game''
# Type a save game name and click ''Save''
# Click ''Quit game''
# Click ''Play''
# Click ''Multiplayer''
# Click ''Load game''
# Choose the save game you just created and click ''Load''
# Choose latency and other settings, then click ''Play''
# Other players can now join the game

== Forces ==

Forces can be manually created via the console. This allows any map/scenario to be used for PvP. This may not be as convenient as a pre-made PvP scenario, as there will be no way for players to turn on/off cease fires other than through the console.

Each created force has its own research progression and different forces may attack each other.

The console commands for setting up and controlling forces are below:

;game.create_force('force 1')
:Creates a force with name "force 1". Default forces are "player", "enemy", and "neutral".
:"player" is the default force for players
:"enemy" is alien force
:"neutral" is special: it is not attacked and can use all / be used by all other forces (e.g., neutral storage containers can be accessed by all)
;game.get_player('friend 1').force = game.forces['force 1']
:Changes the force of "friend 1" to "force 1"
;game.forces['force 1'].set_cease_fire('force 2', true)
:Makes "force 1" cease fire against "force 2". The reverse has to be done separately.
;game.forces['force 1'].set_spawn_position({x=10, y=20}, game.get_surface(1))
:Sets the spawn/respawn point for a particular force to x = 10, y = 20. By default, all players from all forces will spawn at {x = 0, y = 0}.
;for v in pairs(game.forces) do game.local_player.print(v) end
:list all existing forces

== Dedicated/Headless server ==
As of Factorio version 0.12.0 onwards, a dedicated (or headless) server can be started using the --start-server command line option. You can run factorio --help to get a list of all command-line arguments that Factorio accepts.

In the headless mode:
* Graphics are not initialized (faster start up, less memory usage, works on completely headless servers)
* Game starts immediately and loads a save given as a parameter to the command
* The server has no character in game
* Game is paused while there are no players connected (though this can be overridden using the --no-auto-pause option)
* Saves the game on exit (and autosaves normally)

''Please note that there has been a slight change between 0.12, 0.13 and 0.14 in how --start-server (and others) interpret the given parameter. Version 0.12 expected --start-server to be followed by a save name, that was to be found in the saves directory. 0.13 instead expects --start-server to be followed by a path to a save file. I.e. if you did '''factorio --start-server foo''' in 0.12, you probably want to use '''factorio --start-server saves/foo.zip''' in 0.13.''

You will need to create your save file before you start the server, as the dedicated server REQUIRES a save file to be provided. This can easily be done using the --create command-line argument. For example:
<nowiki>./bin/x64/factorio --create ./saves/my-save.zip # This creates a new save, as if by clicking the New Game button in the GUI
./bin/x64/factorio --start-server ./saves/my-save.zip # This starts a server that will host the file created on the previous line</nowiki>

Starting with version 0.13, --create also accepts --map-gen-settings if you want to use non-default map generation. To use it, create a file with the desired map settings (see the file data/map-gen-settings.example.json for an example), and run:
<nowiki>factorio --create saves/my-save.zip --map-gen-settings path-to-file-with-desired-map-generation-settings.json</nowiki>

Starting with version 0.14.12, factorio has moved some command-line options into the server-settings.json file. Starting factorio server requires you to specify the location of the server-settings.json file. By default this is in the factorio data folder. For example to start factorio using the most recent saved map, you would run:
<nowiki>./factorio --start-server-load-latest --server-settings ./data/server-settings.json</nowiki>

Below are basic instructions for starting a dedicated server on Windows and Linux.

==== Windows ====

* Go to your Factorio.exe folder (Probably 'C:\Program Files\Factorio\bin\x64\')
* Create a text document and write into it 'Factorio.exe --start-server YOURSAVEGAME.zip'
** If you haven't already done, replace YOURSAVEGAME with your savegame name
* Save the file as server.bat. Important: At 'Save as type:' select 'All Files'
* Use the server.bat to start your server.
* The console log will be shown in the window.
* To close the server, select the console window press Control+C. If you just close it without pressing this, it will not save your game.
* Forward Ports: You will find detailed instructions for your specific router on the web

==== Linux ====

This step-by-step guide has been verified on fresh CentOS 7 and RHEL 7 installs but should be applicable with little to no changes on most distribution.

The guide assumes you will install the headless server under '''/opt/factorio''', adjust paths according to your own setup. We will also suggest that you run the Factorio server as a separate user to harden security of your setup.

Note that there are two distinct packages for Linux that can be used to run a headless server. First is the usual Linux download, that contains the full game. The other is the special [https://www.factorio.com/download-headless/stable headless package]. The headless package does not contain any files irrelevant for a pure server, such as graphics and sounds. It is also not linked against libraries that may not be present on a server machine, such as Xlib, libGL or libasound.

This guide does not handle firewall/port forwarding since this can be done in various ways on Linux (make sure to read up how this is done as a Linux admin on your particular distribution)

You can use the [https://github.com/Bisa/factorio-init Linux factorio-init script] to start/stop your headless server in a much better way. The script will ensure you only ever use the most recent save when your server starts (even if that was an auto-save) while also letting you set a number of other settings like Autosave frequency and Latency settings. This script will also simplify updating the server when combined with the [https://github.com/narc0tiq/factorio-updater Linux factorio-updater script].

* Download the selected package -- either full game or the headless package -- and upload the linux tar.gz package to your server /tmp
* Extract the package in /tmp to /opt/factorio
<nowiki>#cd /opt/
#tar -xzf /tmp/factorio.tar.gz # Use the correct filename. It includes the factorio version number</nowiki>
* Add a new user to your system and assign ownership of the factorio dir to it (please, do not run as the root user)
<nowiki>#useradd factorio
#chown -R factorio:factorio /opt/factorio</nowiki>

* Try the binary
<nowiki>#su factorio
#/opt/factorio/bin/x64/factorio --start-server savename</nowiki>
As long as it fails saying it cannot find/open the savename.zip you are set! Just upload a save from your own computer and put it in the /opt/factorio/saves directory, or use the --create ./saves/newgame.zip argument

== How to List Your Server-Hosted Game on the Matching Server ==
In order to publish the game to the matching server, Factorio needs to be given some more information than just the save file location. These information are provided in a ''server settings file''.

To create a server settings file, look at the example file located in '''data/server-settings.example.json''' in the Factorio [[Application Directory]]. The recommended way is to make a copy of this example file and edit the copy.

The following values can be changed:
* Name: This will be the name under which the server will be listed in the server browser
* Description: A brief description of your server
* Tags: A list of game tags
* Max Players: Allows you to limit the number of players that can be connected to the server at the same time. If you want no limit, just set max_players to 0.
* Visibility for server browser: May be either public, lan or hidden.
** Public: The server will appear in the public server list. This requires the login credentials below to be filled in.
** LAN: The server will not appear in the public server list, but will be available through the Play On LAN button
** Hidden: Clients will have to connect using the server's IP address
* User credentials using a username and password or authentication token: These are necessary if you wish to make the server public. Otherwise, they can be left empty.
** For security reasons it is recommended to use authentication token as this document is stored as plaintext. Though it should be noted that an authentication token is a sensitive piece of information as well, and you are well-advised to keep it secret.
* Server Password
** Field name is game_password
* Whether to verify user identity
(There are additional values in v0.14 of factorio.)

Blueprint

2016-10-04T01:13:30Z

Luc: Updated info for the latest version

{{Languages}}
{{:Blueprint/infobox}}

Blueprints are a smart way to 'copy & paste' parts of a factory with help of [[Construction robot]]s.

== Usage ==

Blank blueprints can be crafted in the crafting menu in the top row of the production tab. The blank blueprint can now be used to 'copy' a set of buildings.

For example, copying this small laser defense setup:

[[File:Blueprint-example-01.png]]

=== Create a blueprint ===

To create a blueprint select the blueprint item out of the toolbar or the inventory. With the blueprint icon shown next to the mouse cursor, click and hold the left mouse button and drag a box as large as needed. All buildings which will be included in the blueprint will be highlighted with a green square. Once everything to 'copy' is inside the drag box, release the mouse button, and the 'Blueprint icon setup' menu will open.

[[File:Blueprint-example-02.png‎]]

=== Blueprint icon setup ===

On the top left of the 'Blueprint icon setup" menu there are four icon slots. The game chooses automatically the number of icons and which are pre-selected depending on the number of buildings that are included. This can be changed by simply clicking on the icons to choose the desired ones.

On the top right there are two icons to 'create blueprint' and 'cancel blueprint'. The 'create blueprint' icon will also show a preview of how the blueprint icon will look after creation. The 'Blueprint preview' just shows the preview of the blueprint.

On the bottom the 'Total' number of buildings included in the blueprint is shown.

Finally, create the blueprint if everything is fine or cancel it. Cancelling does not consume the blueprint item. The created blueprint will be in the toolbelt or the inventory (or dropped to the ground if no toolbelt/inventory slot is available).

[[File:Blueprint-example-03.png‎]]

=== Placing the blueprint ===

To use/place the created blueprint select it from the toolbelt or inventory. The whole building setup of the blueprint will be shown at your mouse cursor. It is possible to place it rotated, press the default key "R" to rotate. The blueprint can be placed anywhere inside the green (or orange) 100x100 area of a [[Roboport]], or within range of a [[personal roboport]] installed in [[basic modular armor|modular armor]].

[[File:Blueprint-example-04.png‎]]

After the blueprint gets placed somewhere, the buildings are placed as ghost buildings. [[Construction robot]]s will now start to pick up the needed items from the construction network/the player inventory (if using a personal roboport) and place them at the ghost buildings. The required items need to be in the network in an [[Active Provider chest]], a [[Passive Provider chest]] or a [[Storage chest]].

[[File:Blueprint-example-05.png‎]]

=== Viewing and clearing a blueprint ===

Right clicking on a blueprint allows you to can view and clear it. By clearing it, it will become blank can be set again. Clearing no longer requires an [[Electronic circuit]] since 0.13.

== Additional information ==

* Once a blueprint is created it can be used unlimited times.
* To place a blueprint that is blocked by existing buildings you can hold shift to place the things that aren't blocked.
* Buildings marked for destruction will not block placing a blueprint. The building cannot be placed until a construction bot can remove it. This can cause an item outside the construction zone to block construction of a 2x2 building on the edge of the zone.
* It is unknown if there is a limit for the size of a blueprint. But it is at least bigger then one screen, even when zoomed out all the way.
* Placing very large blueprints can be problematic when parts of it are out of the roboport construction area. If roboports are part of the blueprint and are placed inside the construction area they will extend the logistics zone as soon as it is powered up.
* Since 0.13, blueprints can be stored in a [[Blueprint book]]. This can store many blueprints while taking only one inventory spot.
* Editing a blueprint is not possible, it always has to be re-created after clearing.

Multiplayer

Luc: Added note about server browser in web browser

{{Languages}}

Factorio supports multiplayer games in additional to the single-player campaign and scenarios. By default, multiplayer games run the CO-OP [[Game modes and options|freeplay scenario]] where all players work together to launch a rocket with a satellite into space. Other scenarios, including PvP maps, are available for download from the [https://forums.factorio.com/viewforum.php?f=36&sid=93d1fbe9336d31d6bac60847b6c97985 Maps and Scenarios forum].

Currently, joining a multiplayer game requires either that all players be on the same LAN or that the host have a public IP address. The next version of Factorio, 0.13, will support a public multiplayer game lobby for locating games as well as [https://www.factorio.com/blog/post/fff-76 NAT punching] to make connecting to a server without a public IP address more seamless.

== History ==

Because of the potentially immense amount of activity on a map, the game engine utilizes a [https://www.factorio.com/blog/post/fff-76 lock step architecture]. All instances of the game run full simulations of the entire world and only player actions are transferred across the network.

Multiplayer games were introduced to Factorio with version 0.11.0. The only connection method available was peer-to-peer mode which meant every player had to be able to directly communicate with every other player. In version 0.12.4, a client-server mode of communication was introduced in which the server (either a dedicated one or the player who hosted the game) relays messages to all peers. This means that direct connection between all players is no longer necessary. The client-server mode will be the only available in 0.13.

As of version 0.12.0, the game features "latency hiding" mechanics where the game simulates some of the player's actions locally to make some common interactions (such as moving the player's character) more fluid. Latency hiding is enabled by default, but it can be enabled or disabled in Options → Other → Enable multiplayer latency hiding. Not every action is a part of latency hiding – most notably, car or train driving and shooting are not a part of it.

== Setting Up a Multiplayer Game ==

Use the ''Multiplayer'' button in the game menu to start a multiplayer game. One player starts the game and acts as the host. That player should provide the other players with his or her IP address. They can then use that IP address to join the host's game.

Other notes and tips:

* All game instances need the installation of exactly the same game-versions and mods.
* Factorio uses the port '''34197'''. The port can be changed in the [[Application Directory|config]] file.
* Factorio uses '''UDP only'''. Make sure you configure your router's port forwarding correctly. (The game builds it's own "reliable delivery" layer built on UDP to deal with packet loss and reordering issues.)
** Make sure there is no firewall or anti-virus blocking the UDP-packets.
* See the [[#Connecting to a Server Behind NAT|section below]] for help configuring your networking set up.
* The hard limit for the number of players is [https://forums.factorio.com/viewtopic.php?f=53&t=6481&p=50661#p50586 65535]. :)

=== Voice Chat ===
* It is recommended that players use voice chat (TeamSpeak, Skype) because you need to talk a lot to coordinate connections, building, handling attacks, etc. TeamSpeak servers are posted in the [https://forums.factorio.com/viewforum.php?f=53 multiplayer forum].

=== Finding Other Players ===

* Use the [https://forums.factorio.com/viewforum.php?f=53 multiplayer board in the forum].
* Many players use other software like Evolve to meet other players. This also has the "advantage" of creating a virtual LAN among the players. See down under software.
* Some also use [https://forums.factorio.com/viewtopic.php?f=5&t=9136 Steam] to find other players.
* There is an external [http://lgms.nl/p/factorio-serverlist/ server browser] with various search options.
* Tell your friends to buy Factorio, then play with them!

=== Connecting to a Server Behind NAT ===

Factorio requires that the server (in client-server mode) or all peers (in peer-to-peer mode) have a publicly accessible IP address or that all players are on the same LAN. If you are behind NAT, you must set up port forwarding ([[Multiplayer#Playing_over_LAN_.2F_Internet|see above]] for port number) or use virtual LAN software such as Hamachi or Evolve.

By default, multiplayer games will be launched in client-server mode (also [http://www.factorio.com/blog/post/fff-99 multiplayer forwarding] mode). In this mode, all clients send their network traffic to the server and the server forwards the traffic to the other clients. The advantage of this is that it allows games where some players are inside a LAN and others are outside. The disadvantage may be slightly more lag as packets must travel an extra hop (through the server). Multiplayer games may be launched in peer-to-peer mode to disable this forwarding behavior by checking the ''Use peer-to-peer communication'' box when starting the game as the host. Using peer-to-peer is no longer recommended and will be removed entirely in 0.13.

== Game Types ==

=== Co-op ===

In co-op mode, all players are on the same force which means all players share the same research progression, any player can access items stored in a container built by any other player, and defensive structures built by any player will not target any other player.

To start a co-op game:

# Launch Factorio
# Click ''Play''
# Click ''Multiplayer''
# Click ''New game''
# Select map generator options, then click ''Generate''
# Choose latency and other settings, then click ''Play''
# Other players can now join the game

=== PvP ===

In PvP mode, players can be on different forces. Each force can have one (free-for-all) or more players (teams). Each force has its own independent research progression. Additionally, each force's [[Turret|turrets]] and [[Combat Robot Capsules|combat bots]] will attack other players as enemies, unless a cease fire is set. Note that, depending on the scenario, cease fires may be unidirectional — setting a cease fire with an opposing force does not guarantee a cease fire from them in return.

To start a PvP game, you must have a PvP-compatible scenario downloaded (or use the console commands to manually assign players to different forces, [[#Forces|see below]]). PvP scenarios can be found in the [https://forums.factorio.com/viewforum.php?f=36&sid=93d1fbe9336d31d6bac60847b6c97985 Maps and Scenarios forum].

'''Example PvP scenarios:'''

* [https://forums.factorio.com/viewtopic.php?f=36&t=15052 Various scenarios by Klonan]

After downloading a PvP scenario, you need to start the scenario as a single player custom scenario, save it, then load it as a multiplayer game. Otherwise, Factorio will launch the default freeplay scenario in co-op mode. In detail:

# Download the scenario and place the scenario directory in the ''scenarios'' directory within your [[Application_directory#Directory_locations_by_OS_and_installation_method|user data directory]].
# Launch Factorio
# Click ''Play''
# Click ''Custom scenario''
# Choose the PvP scenario you want under ''User scenarios'' and click ''Create''
# (Depending on the scenario, you may need to set the map generation settings and click ''Generate'')
# Hit Escape and click ''Save game''
# Type a save game name and click ''Save''
# Click ''Quit game''
# Click ''Play''
# Click ''Multiplayer''
# Click ''Load game''
# Choose the save game you just created and click ''Load''
# Choose latency and other settings, then click ''Play''
# Other players can now join the game

== Forces ==

Forces can be manually created via the console. This allows any map/scenario to be used for PvP. This may not be as convenient as a pre-made PvP scenario, as there will be no way for players to turn on/off cease fires other than through the console.

Each created force has its own research progression and different forces may attack each other.

The console commands for setting up and controlling forces are below:

;game.create_force('force 1')
:Creates a force with name "force 1". Default forces are "player", "enemy", and "neutral".
:"player" is the default force for players
:"enemy" is alien force
:"neutral" is special: it is not attacked and can use all / be used by all other forces (e.g., neutral storage containers can be accessed by all)
;game.get_player('friend 1').force = game.forces['force 1']
:Changes the force of "friend 1" to "force 1"
;game.forces['force 1'].set_cease_fire('force 2', true)
:Makes "force 1" cease fire against "force 2". The reverse has to be done separately.
;game.forces['force 1'].set_spawn_position({x=10, y=20}, game.get_surface(1))
:Sets the spawn/respawn point for a particular force to x = 10, y = 20. By default, all players from all forces will spawn at {x = 0, y = 0}.
;for v in pairs(game.forces) do game.local_player.print(v) end
:list all existing forces

== Dedicated/Headless server ==
As of Factorio version 0.12.0 onwards, a dedicated (or headless) server can be started using the --start-server command line option. You can run factorio --help to get a list of all command-line arguments that Factorio accepts.

In this mode:
* Graphics are not initialized (faster start up, less memory usage, works on completely headless servers)
* Game starts immediately and loads a save given as a parameter to the command
* The server has no character in game
* Game is paused while there are no players connected (though this can be overridden using the --no-auto-pause option)
* Saves the game on exit (and autosaves normally)

''Please note that there has been a slight change between 0.12 and 0.13 in how --start-server (and others) interpret the given parameter. Version 0.12 expected --start-server to be followed by a save name, that was to be found in the saves directory. 0.13 instead expects --start-server to be followed by a path to a save file. I.e. if you did '''factorio --start-server foo''' in 0.12, you probably want to use '''factorio --start-server saves/foo.zip''' in 0.13.''

You will need to create your save file before you start the server, as the dedicated server REQUIRES a save file to be provided. This can easily be done using the --create command-line argument. For example:
<nowiki>./bin/x64/factorio --create saves/my-save.zip # This creates a new save, as if by clicking the New Game button in the GUI
./bin/x64/factorio --start-server saves/my-save.zip # This starts a server that will host the file created on the previous line</nowiki>

Starting with version 0.13, --create also accepts --map-gen-settings if you want to use non-default map generation. To use it, create a file with the desired map settings (see the file data/map-gen-settings.example.json for an example), and run factorio --create saves/my-save.zip --map-gen-settings path-to-file-with-desired-map-generation-settings.json

Below are basic instructions for starting a dedicated server on Windows and Linux.

==== Windows ====

* Go to your Factorio.exe folder (Probably 'C:\Program Files\Factorio\bin\x64\')
* Create a text document and write into it 'Factorio.exe --start-server YOURSAVEGAME.zip'
** If you haven't already done, replace YOURSAVEGAME with your savegame name
* Save the file as server.bat. Important: At 'Save as type:' select 'All Files'
* Use the server.bat to start your server.
* The console log will be shown in the window.
* To close the server, select the console window press Control+C. If you just close it without pressing this, it will not save your game.
* Forward Ports: You will find detailed instructions for your specific router on the web

==== Linux ====

This step-by-step guide has been verified on fresh CentOS 7 and RHEL 7 installs but should be applicable with little to no changes on most distribution.

The guide assumes you will install the headless server under '''/opt/factorio''', adjust paths according to your own setup. We will also suggest that you run the Factorio server as a separate user to harden security of your setup.

Note that there are two distinct packages for Linux that can be used to run a headless server. First is the usual Linux download, that contains the full game. The other is the special [https://www.factorio.com/download-headless/stable headless package]. The headless package does not contain any files irrelevant for a pure server, such as graphics and sounds. It is also not linked against libraries that may not be present on a server machine, such as Xlib, libGL or libasound.

This guide does not handle firewall/port forwarding since this can be done in various ways on Linux (make sure to read up how this is done as a Linux admin on your particular distribution)

You can use the [https://github.com/Bisa/factorio-init Linux factorio-init script] to start/stop your headless server in a much better way. The script will ensure you only ever use the most recent save when your server starts (even if that was an auto-save) while also letting you set a number of other settings like Autosave frequency and Latency settings. This script will also simplify updating the server when combined with the [https://github.com/narc0tiq/factorio-updater Linux factorio-updater script].

* Download the selected package -- either full game or the headless package -- and upload the linux tar.gz package to your server /tmp
* Extract the package to /opt/factorio
<nowiki>#cd /opt/</nowiki>
* Add a new user to your system and assign ownership of the Factorio dir to it (please, do not run as the root user)
<nowiki>#useradd factorio
#chown -R factorio:factorio /opt/factorio</nowiki>

* Try the binary
<nowiki>#su factorio
#/opt/factorio/bin/x64/factorio --start-server savename</nowiki>
As long as it fails saying it cannot find/open the savename.zip you are set! Just upload a save from your own computer and put it in the /opt/factorio/saves directory

== How to List Your Server-Hosted Game on the Matching Server ==
In order to publish the game to the matching server, Factorio needs to be given some more information than just the save file location. These information are provided in a ''server settings file''.

To create a server settings file, look at the example file located in '''data/server-settings.example.json''' in the Factorio [[Application Directory]]. The recommended way is to make a copy of this example file and edit the copy.

The following values can be changed:
* Name: This will be the name under which the server will be listed in the server browser
* Description: A brief description of your server
* Tags: A list of game tags
* Max Players: Allows you to limit the number of players that can be connected to the server at the same time. If you want no limit, just set max_players to 0.
* Visibility for server browser: May be either public, lan or hidden.
** Public: The server will appear in the public server list. This requires the login credentials below to be filled in.
** LAN: The server will not appear in the public server list, but will be available through the Play On LAN button
** Hidden: Clients will have to connect using the server's IP address
* User credentials using a username and password or authentication token: These are necessary if you wish to make the server public. Otherwise, they can be left empty.
** For security reasons it is recommended to use authentication token as this document is stored as plaintext. Though it should be noted that an authentication token is a sensitive piece of information as well, and you are well-advised to keep it secret.
* Server Password
** Field name is game_password
* Whether to verify user identity

Turret

Luc: /* Flamethrower Turret */

{{Languages}}
'''Turrets''' are defensive structures that can be crafted after being researched. They come in three different types with different health, shooting speed, range, ammunition, damage type and damage per shot.

__FORCETOC__

== Gun Turrets ==

Gun turrets are very basic and cheap defensive structures and the simplest element of automatic defenses. They use magazines for ammunition which can be refilled manually or by [[inserters]]. They do not require power and can operate practically anywhere as long as they have sufficient ammunition. Gun turrets deal double damage per shot as compared to the man-portable [[pistol]] and [[submachine gun]], but have somewhat lower fire rate than the latter, so absent any turret-specific upgrades it does 1.33 times as much damage per second as the submachine guns. The gun turret receives bonuses from technologies that improve bullets so it keeps pace with the submachine gun as those improve, and they also receive bonuses from their own damage upgrade. These two damage effects stack multiplicatively: fully upgraded, bullets do 2.2 times as much damage as a standard bullet, and turrets do 2.2 times as much damage as a standard turret, so bullets from a turret do 2.2×2.2=4.84 times as much damage as without the upgrades, totaling 19.36 damage from [[Regular_Magazine|regular]] and 48.4 damage from [[Piercing_Rounds_Magazine|piercing]] bullets, more than fully-upgraded laser turrets can provide, though still not quite enough to kill medium spitters in a single shot.

If one plans to exclusively use gun turrets, using a [[Train]] to send ammo to restock distant turrets is very effective.

== Laser Turrets ==

Laser turrets are an advanced defense building with a longer range, good damage and use [[Electric network|electricity]] to operate (and a smaller amount of energy when idle). By dealing '''laser damage''' they don't face any resistances ([[enemies]] receive full damage) but have a lower rate of fire than gun turrets. Each shot costs a constant 800kJ of energy; as the shooting speed increases through upgrades, so too does the power required to keep firing.

Since using laser turrets to ward off attacks can cause electricity usage spikes, using [[Basic accumulator|accumulators]] to offset the cost is recommended to keep the rest of the network fully functional.

==Flamethrower Turret==

New in version 0.13, Flamethrower turrets provide literal fire support, setting enemies on fire and doing damage over time. Unlike the previous turrets, they have a limited firing arc, therefore should be place at choke points or behind walls. They use liquids as ammunition, which requires dedicated fluid pumping, capable of using crude oil, heavy oil, or light oil. Different liquids provide further damage bonuses. (Light oil yielding a 10% damage boost.)

Currently, flamethrower turrets have a tendency to miss the first row of biters, as unlike the laser and gun turrets they do not have a seeking projectile, instead firing over the heads of the first row. Due to this, gun/laser turrets will be necessary in addition to flame turrets. The second biters in line will not be so lucky, however. When fully upgraded, Flamethrower turrets are capable of doing 145.2/s Fire damage plus an additional 217.8/s damage for 8 seconds. This makes them far more powerful than the gun turret or the laser turret, especially considering Biters' lack of resistance to fire. The high damage cheapens the cost of liquids.

The optimal attack for flamethrower turrets to handle would be a very linear attack, where the enemy attacked in a line formation, to ensure most attackers end up walking through the pool of fire left by the turret.

Steam engine

2016-09-04T00:55:15Z

Luc: Did some testing with water/oil temperatures and a steam engine.

{{Languages}}
{{Machinery
|health =300
|stack_size =10
|poweroutput =510 kW
|input =time, 0.5 + iron gear wheel, 5 + pipe, 5 + iron plate, 5
|raw =time, 5.5 + iron plate, 20
|producers =manual + assembling machine 2 + assembling machine 3
}}

Steam engines are used to produce electricity. They do this by taking in hot water and converting it into electricity. The hotter the water the more electricity can be produced. If there is an overabundance of electricity then steam engines will reduce their production to match consumption.

Hovering the mouse over a steam engine will display information for that particular steam engine: current production as well as maximum productivity.

It is possible to chain multiple steam engines together as water will pass through them. The current optimal ratio is 1 [[offshore pump]] : 14 [[boiler]]s : 10 [[steam engine]]s.

'''Steam engines themselves don't produce any pollution.''' ([[Boiler]]s do!)

== Using other liquids ==

The steam engine can use any type of liquid to generate electricity. This can be used to get rid of unused oil-products. Just fill unusable oil products into a steam engine and it will destroy the liquids (cold liquids will be destroyed at a rate of [https://forums.factorio.com/viewtopic.php?p=144748#p144748 6.0 fluid / second]). It works the same as for cold water; you don't need to warm it. If you heat the liquid before that, the hot oil will produce electrical power, just like with hot water.

By default, water is 15°C and oils are 25°C. The steam engine happens to work with water from 15°C and oils from above 25°C (a complete coincidence). An oil temperature of 25.22°C will get you about 1.3KW of power. Water works without any heating, producing a few watts of power. Heating up water or oils makes no difference: heating one liter of water from 15 to 16 degrees takes just as much energy as heating one liter of oil from 25 to 26 degrees[http://because.a.tweet.doesnt.fit.lucb1e.com/?text=1.4k+water+15%B0C-%3E17.73%B0C+and+1.4k+light+oil+25%B0C-%3E27.82%B0C%2C+both+using+1+coal+in+a+boiler%2C+filling+an+empty+tank+from+a+full+tank+until+the+coal+boiler+runs+out.+I+stopped+a+bit+early+on+the+water+one+and+the+difference+seems+negligible. (OC)]. It was not tested how much energy the steam engine produces with 16°C water versus 26°C oil, but it probably does not warrant using oils instead of water.

In general you should convert the unusable oil products into useables, instead of just making electricity out of it!

Rocket part

2016-08-25T01:24:48Z

Luc: Added some calculations I did into the true "total raw" of a rocket as required to win the game.

{{Item
|input =time, 3 + low density structure, 10 + rocket fuel, 10 + rocket control unit, 10
|technologies =rocket silo
|producers =rocket silo
|consumers =rocket silo
}}

'''Rocket parts''' are created inside of the [[rocket silo]]. Each completed part contributes 1% towards the completion of the rocket. Once all 100 rocket parts have been completed the rocket silo will display a rocket ready to be launched within the silo and the rocket silo interface will contain a LAUNCH button.

== Building the Rocket ==

The rocket needs 100 parts; each part needs 3 ingredients; those ingredients need other ingredients; etc. In total, one rocket will need the following items:

100 RocketPart
1 000 Low Density Structures
1 000 Rocket Control Units
1 000 Rocket Fuel
10 000 Light Oil
10 000 Processing Units
10 000 Solid Fuel
10 000 Speed Modules
10 000 Steel
35 000 Sulfuric Acid
70 000 Advanced Circuits
145 000 Coal
145 000 Plastic
175 000 Sulfur
390 000 Electronic Circuits
475 000 Iron Ore
475 000 Iron Plates
730 000 Copper Ore
730 000 Copper Plates
960 000 Petroleum Gas
1 450 000 Copper Cable

To win the game (or to update the Rockets Sent counter in the left top), you additionally need a satellite. When you hover over it, it mentions the "total raw" already. However, this does not include the material needed for Processing Units, Batteries and Steel since these are seen as "raw ingredients" (they cannot be crafted by hand). Still, you can't make a battery (or steel, or processing units) without iron plates, so you still need to mine the ore. Adding it all up, the total cost for the satellite is:

5 Radar
25 Gear Wheels
50 Rocket Fuel
100 Accumulators
100 Low Density Structures
100 Processing Units
100 Solar Panels
200 Advanced Circuits
500 Battery
500 Light Oil
500 Solid Fuel
900 Coal
900 Plastic
1 100 Sulfuric Acid
1 500 Steel
3 925 Electronic Circuit
5 500 Sulfur
7 788 Copper Ore
7 788 Copper Plates
12 575 Copper Cables
13 325 Iron Ore
13 325 Iron Plates
19 200 Petroleum Gas

Added up together, each rocket you launch will set you back:

1 Rocket
1 Satellite
5 Radar
25 Gear Wheels
100 Accumulators
100 Rocket Parts
100 Solar Panels
500 Battery
1 000 Rocket Control Units
1 050 Rocket Fuel
1 100 Low Density Structures
10 000 Speed Modules
10 100 Processing Units
10 500 Light Oil
10 500 Solid Fuel
11 500 Steel
36 100 Sulfuric Acid
70 200 Advanced Circuits
145 900 Coal
145 900 Plastic
180 500 Sulfur
393 925 Electronic Circuits
488 325 Iron Ore
488 325 Iron Plates
737 788 Copper Ore
737 788 Copper Plates
979 200 Petroleum Gas
1 462 575 Copper Cables

Or, as a "total raw":

145 900 Coal
488 325 Iron Ore
737 788 Copper Ore
979 200 Petroleum Gas

Crude oil is not in the list because there are multiple ways to process it into petroleum gas and other oils. Water is also not included because it, again, depends on how you process your oils. A rough estimate is that you will use a million units of water and two million units of crude oil in the production of the satellite + rocket.

Nightvision

2016-05-04T14:15:12Z

Luc: Multiple night vision units does nothing (I tried -- I hoped it might, like exoskeletons are additive, improve vision or something).

{{Languages}}
{{Item
|name =Night Vision
|extra1 =<tr><td style="text-align: left;">Size</td><td>3x2</td></tr>
|input =Time, 10 + Steel plate, 10 + Advanced circuit, 5
|technologies =Night vision (research)
|producers =Manual + Assembling machine
}}
<onlyinclude>
[[File:night-vision-example-1.png|thumb|256px|Visibility at night.]]

Having [[Night vision]] in your [[Modular armor|armor]] during the night replaces standard light-dependent vision with a green filter that ignores lighting conditions.

The module activates rather early and deactivates late, meaning that during the dawn and the dusk it actually impairs the vision.

Unlike other items such as exoskeletons or shields, equipping multiple night vision units has no effect.
