Artillery targeting remote

2026-03-24T17:35:26Z

Joeykins: /* History */ removed crafting recipe

{{Languages}}{{:Infobox:Artillery targeting remote}}
The '''Artillery targeting remote''' is used to manually designate targets for the [[artillery wagon]] and [[artillery turret]] by clicking somewhere with them - either from the map or normally from the world. Targets expire when an artillery wagon or turret shoots the spot they designate, or after 1 minute has elapsed. Placing targets with an artillery targeting remote does not use the item up - usually only one remote needs to be crafted per game. Using this item massively increases the range of artillery compared to having artillery fire automatically.

The number next to the remote when it is held in hand or pinned to the quickbar indicates how many artillery wagons or turrets are in range and contain ammunition. The remote has no effect if a designated location is outside of the range of all artillery.

Submachine gun

2026-03-24T14:53:46Z

Joeykins: clarified the range increase vs pistol

{{Languages}}{{:Infobox:Submachine gun}}
The '''submachine gun''' is an upgrade from the [[pistol]]. It fires the same ammunition types and deals the same damage as the pistol, but has increased range and a much higher rate of fire. This same type of weapon is installed in the [[car]] and [[tank]]; the car and tank's version of the submachine gun fires +5 rounds per second and has +2 range compared to the handheld one. This weapon can easily handle moderate waves of small biters, even with [[Firearm magazine|regular ammunition]], but destroying [[Nests|nests]] efficiently requires damage upgrades or the more expensive [[Piercing rounds magazine|piercing round]]. It is much more efficient to toggle between the submachine gun and a [[Shotgun|shotgun]], using the SMG against biters and close-range shotgun blasts against the nest.

* Inventory filter slots can be copy-pasted from empty slots onto empty slots using the stack transfer/split controls (shift + left click, shift + right click by default).
=== Balancing ===
* The productivity module pollution addition was lowered (30%->5%, 40%->7.5%, 50%->10%), as the pollution generated by the machine is already increased by the additional energy production and time, it doesn't need to be so high as the modules are quite expensive already.
* Repair packs have double durability (100->200) and stack size (50->100).
* Changed stack size of raw wood (50->100) so it doesn't fill the inventory so quickly.
* Roboport have decreased transmission power consumption (200kw->50kw) while the robots (and their recharging) has increased power consumption (200kW per recharge slot to 1Mw per slot)
** Basically, covering area by roboports is cheaper, but using robots for transport is more expensive. To keep the personal roboport usefulness, energies used in personal roboport have been all multiplied by 10.
* Inserters are able to squeeze things "slightly" better to belts. more resources.
* Increased size of several green science and few blue science technologies.
* Increased inventory size of cargo wagon. (30->40)
* Oil yield drains to 10% two times slower.
* Big and behemoth enemies spawn 50% slower.
* Armor resistances are applied before the energy shield is used.
* Increased the ghost time to live when something is destroyed from 5 + 5 minutes to 30 + 30 minutes.
* Halved the mining time of rails, rail signals and walls.
* Changed the way evolution factor approaches the maximum (1).
** The addition of evolution factor was changed from addition * (1 - evolution) to addition * (1 - evolution)^2
** This means that the progress gets more slower towards the high values.
* Balanced train acceleration and top speed, additional wagons no longer slow trains so strongly.
* Changed the amount of items requested when copy-pasting assembling machines to requester chests for several recipes.
* Express underground belts require lubricant to match the express belts and express splitters.
* Increased battery equipment power storage, input, and output by a factor of 20.

Joeykins: /* Recipes */ split in to Vulcanus only and usable-anywhere recipes

{{Languages}}
{{:Infobox:Foundry}}
{{About/Space age}}
The '''Foundry''' is a version of the [[assembling machine]] from [[Vulcanus]]{{SA}} that specializes in metallurgy. It has a built-in 50% [[productivity]] bonus.

The foundry can only be crafted on Vulcanus due to its higher atmospheric pressure, but it can be used on other planets once transported via [[space platform]].

== Recipes ==

The Foundry has twenty available unique recipes, of which one must be set before it can begin processing.

Note that the foundry recipe for making [[concrete]] can benefit from [[productivity module|productivity modules]], despite the regular concrete recipe not being able to use them.

Additionally, the foundry can also make other foundries (but only on Vulcanus), all [[Transport belts|belt]] types, and [[holmium plate|holmium plates]]; the recipes are the same as used in assembling machines.

== Efficiency ==

Most of the foundry's recipes are more efficient than creating the same items in a [[furnace]] or [[assembling machine]]. However, because of the built-in +50% productivity bonus (which applies even to items like belts that don't benefit from [[productivity module]]s), and because the same bonus also applies to the recipes for [[molten iron]] and [[molten copper]], the actual efficiency gains from using a foundry are much higher than the value listed in the recipe.

The table below compares the values of the base recipes (with 1 ore = 10 molten metal), and then shows the actual output of the recipe with the default foundry bonuses of 4 crafting speed and 150% productivity (1 ore = 15 molten metal). For example, inserting 200 [[iron ore]] into a foundry with no [[module]]s installed would result in 3,000 [[molten iron]] which could be turned into 450 [[iron plate]]s.

=== Alternate recipe chains ===
Because the foundry can cast iron, steel, and copper plates but can also directly cast various items normally made ''from'' those plates, there exist alternate production chains, where the foundry is used to cast the plates and then another production building is used to create the final product:
* Steel can be produced by casting iron plates and refining them in an [[electric furnace]]
* Gears, iron sticks, pipes, and pipes-to-ground can be crafted by casting iron plates and feeding them to an assembler
* Copper wire can be produced by casting copper plates and feeding them to an assembler or an [[electromagnetic plant]]
* Low density structures can be produced by casting copper plates and steel plates (or, as mentioned above, casting iron plates and converting them to steel in a furnace) and feeding them to an assembler

These alternate production chains can potentially be more resource-efficient than just casting the result directly, albeit at the cost of considerably more machines (and in some cases more high-level, high-[[quality]] modules) for a given rate of output. In this case, the inherent +50% productivity bonus of the foundry does not matter, nor do any productivity modules the foundry has, because those bonuses also apply when casting the metal plates. Instead, the decision is between any productivity bonus the second production machine can provide verses the fact that most of the 'Casting' recipes cost less to begin with. (This inherent advantage is the value listed in the 'Efficiency' column under 'Base recipe values' in the above table.)

==== Steel plates ====

Initially, it seems like the electric furnace, with just 2 module slots, cannot make up for the 67% inherent efficiency boost from the cast-steel recipe. However, steel production also has an [[Steel_plate_productivity_(research)|infinite research]] which adds a productivity bonus; while this bonus applies to both casting steel and smelting steel (and ''doesn't'' apply to casting iron plates in order to smelt them into steel), the 50% inherent productivity and more module slots of the foundry give it a higher bonus to start with, meaning that the same ''absolute'' bonus makes for a larger ''relative increase'' in the electric furnace. (For example, with no productivity modules, researching 5 levels of the technology will take the foundry from 150% productivity to 200% productivity, boosting its output by a third, while the furnace will go from 100% productivity to 150% productivity, boosting its output by a half.) With the right combination of high-quality [[productivity module 3]]s and steel plate productivity research, it is possible to make the electric furnace production chain more efficient.

For example, a foundry with 4 legendary productivity module 3s (+25% productivity each) casting iron plates feeding an electric furnace with 2 legendary productivity module 3s and a +50% steel plate productivity has exactly the same overall efficiency as a foundry with 4 legendary productivity module 3s and the same +50% steel plate productivity casting steel plates directly, with both producing exactly 1 steel plate per 10 units of molten iron. Any additional research past that point will make the electric furnace production chain strictly better. If using mere rare productivity module 3s (+16% productivity each) instead, the changeover happens somewhere between +150% and +160% research.

Additionally, with enough levels of steel plate productivity research, it is possible to reach the hard cap of 400% efficiency. Thus the absolute maximum efficiency possible for casting steel is 4/3 steel plates per 10 units of molten iron, while the electric furnace production chain can reach 2 steel plates per 10 units of molten iron.

==== Iron gear wheels ====

It is never possible for gears made in an assembler to be more efficient than those made by casting them directly. The cast gears recipe is ''twice'' as efficient as the normal one and no productivity research applies; the highest efficiency possible from an assembler, 200% from an assembler 3 with 4 legendary productivity module 3s, is only just enough to break even.

==== Iron sticks ====

Conversely, the cast iron stick recipe has no inherent resource efficiency at all, thus casting iron plates and then converting them to sticks using an assembler with ''any productivity modules at all'' is more efficient than using that same foundry to cast them directly.

==== Pipes & Pipes to ground ====

Unlike all the other items with alternate production chains here, [[pipe|pipes]] and [[pipe to ground|pipes to ground]] are not intermediate products. Thus it is not possible to use productivity modules on foundries or assemblers which are producing them. Since it ''is'' possible to use productivity modules on a foundry casting iron plates which are then converted to pipes in an assembler, doing so is more efficient than casting them directly.

==== Copper cables ====

Much like iron gears, copper cables have a 200% efficient casting recipe and no researchable productivity bonus, thus it is not possible to produce them more efficiently using an assembler. However, copper cables can also be produced in the [[electromagnetic plant]], which has ''5'' module slots and an inherent +50% productivity boost of its own. So long as the electromagnetic plant's total productivity is greater than 100%, this production chain is more efficient than casting directly. 5 productivity 3s of common quality (+10% productivity each) will give a total productivity of exactly 100%; any better quality modules, or productivity 2s of epic quality or better, will make them more efficient.

==== Low density structure ====

Low density structures are notable because the crafting recipe has an efficiency of ''less'' than 100% with respect to copper, and while its efficiency with respect to iron is greater than 100%, it is less than the inherent efficiency of casting steel plates. Thus, even with no productivity modules or productivity research at all, casting the plates and then creating the low density structures in an assembler is more efficient. However, low density structures also require plastic, and since plastic bars cannot be cast, you are losing out on the inherent +50% productivity bonus the foundry offers:

|}

Note that making low density structures is subject to its own [[Low_density_structure_productivity_(research)|productivity research]], and both that, and the use of productivity modules of any kind, will make the use of the alternate production chain more attractive: the efficiency gain for iron and copper will increase, while the efficiency loss in plastic, while not entirely negated, will shrink. For example, with no efficiency boosts, the alternative production chain is 33% more efficient in iron, 25% more efficient in copper, and 33% less efficient in plastic, but with +100% productivity from research, the alternative production chain is 60% more efficient in iron, 50% more efficient in copper, and only 20% less efficient in plastic.

Additionally, the hard cap of 300% productivity applies here, too, and this ''can'' entirely negate the penalty to plastic, though the level of research required to do do is considerable.

The low density structure casting recipe does have one advantage: [[Quality]]. Because the only solid input is plastic, all it takes to make low density structures of a particular quality is to have plastic of that quality.

Furthermore, since low density structures can be [[Recycler|recycled]] back to copper and steel plates, one can use this recipe to generate high quality copper and steel plates from plastic, consuming less molten metal than many other means of producing quality plates. Additionally, if the foundry can get to the 300% low density structures productivity cap (via modules and research), then the plastic will (on average) be completely regenerated, allowing a small amount of quality plastic to produce arbitrary amounts of quality copper and steel plates, given sufficient molten metal.

{{About/Space age}}
[[File:Any quality.png|right]]
'''Quality''' is a feature of the [[Space Age]] expansion. It introduces four higher quality levels for all items, structures and equipment with improved attributes. The goal of quality is to allow vertical factory upgrading as alternative to expansion in size. Items of higher quality are created by chance when using quality modules in the producing structure. When Space Age itself is enabled, the two highest quality tiers require technology not available on Nauvis. Different buildings and items can have different attributes that can be upgraded. When hovering over something, the attributes that will be upgraded with quality will be marked with a blue diamond ([[File:Quality info.png]]) in the tooltip.

While players are required to own Space Age to access this feature, quality is a separate mod, and can be activated independent of most Space Age content.

== Quality tiers ==
There are 5 quality tiers in vanilla gameplay, with tier strength in brackets:
* [[File:quality_normal.png|15px]] Normal (0)
* [[File:quality_uncommon.png|15px]] Uncommon (1)
* [[File:quality_rare.png|15px]] Rare (2)
* [[File:quality_epic.png|15px]] Epic (3)
* [[File:quality_legendary.png|15px]] Legendary ('''5''')

Note that legendary quality represents a 2-tier improvement over epic.

== Technologies ==
Certain tiers of quality cannot be created until they have been researched.

|}

== Quality effects ==
The currently known effects of each level of quality are as follows:
* +30% health
* +30% crafting speed
* +30% robot limit (rounded down)
* +1 robot recharge slot for [[personal roboport]]s (both tiers, but not [[roboport]]s)
* +30% robot recharge rate (all roboports)
* +30% positive module effects (rounded down for at least quality modules)
* +10% turret range
* +10% weapon range
* +1 tile reach and +2 wire reach on power poles
* +1 equipment grid size (both dimensions)
* +30% chest inventory size (rounded down)
* +30% increased ammo damage
* +30% inserter rotation speed
** The power consumption of inserters is defined as energy per angle of turn. A 30% faster inserter can turn 30% more angles in a given space of time, so it consumes 30% more energy.
* -16.67% (1/6) resource drain on miners and [[pumpjack]]s
** This is multiplicative with [[productivity]]
* +30% [[solar panel]] output
* +100% (+5 MJ) capacity on accumulators
* +30% capacity on [[personal battery|personal batteries]] (all three tiers)
* +30% output rate on [[boiler]]s, [[steam engine]]s, [[steam turbine]]s, [[accumulator]]s (also affects input rate), and [[nuclear reactor]]s
** Note that consumption and pollution are also increased at the same rate
* +30% reach and efficiency for lightning [[lightning rod|rods]] and [[lightning collector|collectors]]
* -16.67% (1/6) power consumption on [[beacon]]s
* +1 to both continuous coverage distance and exploration coverage distance in [[radar]]s
* +100% durability on consumable items ([[repair pack]]s, [[science pack]]s)
* +5% fork chance on the [[tesla turret]] and tesla ammo for the tesla gun
* [[Asteroid collector]]s:
** +5% arm speed
** +1 arm
** +10% active power consumption per arm and +10% drain
** +2 collection area size (both dimensions)
** +5 storage size

These effects are per quality strength and additive: a Legendary (5 tier-levels) [[Productivity module 3]] (base +10% productivity) would grant 25% productivity.

Some buildings only get increased health, with no special effect. Examples are:
*Buildings related to [[Circuit network]]s and [[Rail signal]]s
*[[Transport belt]]s
*[[Pipe]]s
*[[Wall]]s
*[[Locomotive|Trains]]
*[[Cargo wagon]]s

== Creating high-quality items ==

There are two ways to create an item with above normal quality: The player must either use ingredient items of the same quality, or use quality modules for a random chance of a higher-quality item.

=== Quality ingredients ===
Recipes that consume items have variations for each quality that the items might take. When setting such a recipe in a production unit, an ingredient quality must be selected. For these variations, the set of ingredients required is the same, except that all item ingredients must have the specified quality. Recipes that consume only fluids do not have quality variations. If they produce items, those items will be normal quality unless affected by quality modules. Recipes that fill or empty [[barrel]]s and recipes that produce the same item they consume ([[kovarex enrichment process]] and [[fish breeding]]) do not accept quality modules.

Item ingredient quality requirements are exact, not minimum. For example, one can not combine uncommon [[iron plate]]s with rare [[battery|batteries]] to make an [[accumulator]] of any quality. One must therefore ensure that high-quality items do not clog up belts and starve production units of lower-quality items.

As fluids do not possess any quality, they are exempt from ingredient quality requirements; the same [[lubricant]] can be used to create [[electric engine unit]]s of any quality.

=== Quality modules ===
{{Main|Quality module}}
[[File:quality_module_animated.png|64px|right]]'''Quality modules''' allow crafting machines to produce items of a higher quality than their ingredients. Each module adds a quality chance to a machine, depending on its tier and quality. See the following table for all quality chances:

{|class="wikitable" style="text-align: center;"
! {{Diagonal split header|Module|Quality}} !! [[File:quality_normal.png|Normal|32px]] !! [[File:quality_uncommon.png|Uncommon|32px]] !! [[File:quality_rare.png|Rare|32px]] !! [[File:quality_epic.png|Epic|32px]] !! [[File:quality_legendary.png|Legendary|32px]]
|-
! {{Icon|quality_module}}
| +1% || +1.3% || +1.6% || +1.9% || +2.5%
|-
! {{Icon|quality_module_2}}
| +2% || +2.6% || +3.2% || +3.8% || +5%
|-
! {{Icon|quality_module_3}}
| +2.5% || +3.2% || +4% || +4.7% || +6.2%
|}

When working out the odds of improving quality, a machine starts with the sum of the quality chance of all its modules. When the machine produces an item, it performs a random roll with that chance to succeed. If it succeeds, the product is upgraded 1 level from its ingredients. If the product was upgraded, the machine repeats this process, now with a constant 10% chance of passing, rolling and upgrading until a roll fails.

When using quality ingredients as an input, the base quality is the quality of the recipe. You can only use items with the same quality as input.

Quality modules are only required to ''improve'' quality, crafting will always give the base quality of the used items. Additionally, the odds of improving from a given base quality is the same as improving the same number of tiers from Normal quality.

Where Q is quality chance, the following tables present expected outputs for each level of research.

==== Optimal module usage ====
It is optimal to improve quality on the lead-up to the target output item due to the [[recycler]] only giving back 25% of the input items, except for cases where the chosen item has a productivity research available, in which case looping through a recycler is optimal and has no added material cost (ignoring fluids).

The following tables summarize the number of normal crafts (rounded up) needed to produce 1 legendary output using ideal ratios of quality module 3s to productivity module 3s, with 4 matching quality module 3 in the recycler.

It is important to emphasize that these ratios maximize return per input material. If input capacity isn't a concern and the goal is speed rather than material efficiency, then switch out productivity modules for quality modules as needed. Beware, however, that in many cases material inefficiency nearly keeps pace with the legendary output rate.

For example, suppose legendary T3 modules are available and the goal is to produce legendary [[File:Processing_unit.png|link=Processing unit|20px]] processing units. If each electromagnetic plant producing epic quality or below has 4 legendary [[File:productivity_module_3.png|link=Productivity module 3|20px]] productivity module 3 and 1 legendary [[File:quality_module_3.png|link=Quality module 3|20px]] quality module 3, and the electromagnetic plant with the legendary recipe has 5 legendary [[File:productivity_module_3.png|link=Productivity module 3|20px]] productivity module 3, then on average an input of 280 normal [[File:Electronic_circuit.png|link=Electronic circuit|20px]] electronic circuits and 28 normal [[File:Advanced_circuit.png|link=Advanced circuit|20px]] advanced circuits is expected to produce 1 legendary [[File:Processing_unit.png|link=Processing unit|20px]] processing unit.

===== Derivation =====
Derivation of the tables above was as follows: Starting with 1 set of common ingredients, with an assembly quality chance of Q and total productivity bonus of P, the statistical expected number of product is as follows:
{| class="wikitable" style="text-align:center; vertical-align:middle;"
|+
! [[File:quality_normal.png|Normal|20px]] !! [[File:quality_uncommon.png|Uncommon|20px]] !! [[File:quality_rare.png|Rare|20px]] !! [[File:quality_epic.png|Epic|20px]] !! [[File:quality_legendary.png|Legendary|20px]]
|-
| (1 + P) * (1 - Q) || (1 + P) * (Q * (100 - 10-1))|| (1 + P) * (Q * (10-1 - 10-2)) || (1 + P) * (Q * (10-2 - 10-3)) || (1 + P) * (Q * 10-3)
|-
| (1 + P) * (1 - Q) || (1 + P) * Q * 9/10 || (1 + P) * Q * 9/100 || (1 + P) * Q * 9/1000 || (1 + P) * Q * 1/1000
|}

In a similar vein, the same calculations can be done for recycling products, except that there is, in effect, -75% productivity bonus, where only a quarter of the items are returned.

{| class="wikitable" style="text-align:center; vertical-align:middle;"
! [[File:quality_normal.png|Normal|20px]] !! [[File:quality_uncommon.png|Uncommon|20px]] !! [[File:quality_rare.png|Rare|20px]] !! [[File:quality_epic.png|Epic|20px]] !! [[File:quality_legendary.png|Legendary|20px]]
|-
| (1 + -0.75) * (1-Q) || (1 + -0.75) * (Q * (100 - 10-1)) || (1 + -0.75) * (Q * (10-1 - 10-2)) || (1 + -0.75) * (Q * (10-2 - 10-3)) || (1 + -0.75) * (Q * 10-3)
|-
| 0.25 * (1-Q) || 0.25 * Q * 9/10|| 0.25 * Q * 9/100 || 0.25 * Q * 9/1000 || 0.25 * Q * 1/1000
|}

For example, recycling an uncommon ingredient with a Q of 25%:
{| class="wikitable" style="text-align:center; vertical-align:middle;"
! {{Diagonal split header|Input|Output}} !! [[File:quality_normal.png|Normal|20px]] !! [[File:quality_uncommon.png|Uncommon|20px]] !! [[File:quality_rare.png|Rare|20px]] !! [[File:quality_epic.png|Epic|20px]] !! [[File:quality_legendary.png|Legendary|20px]]
|-
| style="background:#424242" | [[File:quality_uncommon.png|Uncommon|16px]] || - || 0.1875 || 0.05625 || 0.005625 || 0.000625
|}

Combining these results allows a 'Transition Matrix' to be developed (see the Wikipedia article [[Wikipedia:Stochastic matrix|Stochastic matrix]]) which after iteration can generate the expected number of legendary products from 1 set of common ingredients via matrix multiplication. An example matrix for P of 50% and Q of 25% for both recycling and assembly is copied below. Note that since legendary products are the goal, they are not recycled.

To iterate this matrix (M) apply the matrix to itself. For example, M6 would indicate 6 iterations, corresponding to 3 crafting steps and 3 recycling steps. To see how much 1 ingredient set produces after a given iteration, x, multiply an input vector by Mx. The vector format follows that of the matrix labels, so with the table arranged as above, left multiply a row vector of ingredient(s) by the matrix. In order to see the expected product of 1 set of normal ingredients, the vector will have '1' in the first column and '0's everywhere else. Likewise, a set of uncommon ingredients will correspond to '1' in the second column of the vector.

It is important to note that since the recycling step has a material loss of 75% most recycling loops will be well behaved and converge quickly.

Extreme productivity from research breaks this pattern and will prevent convergence, but this simply means that there is a positive material cycle, so 1 set of ingredients will produce infinite legendary crafts, on average. The closer the total productivity is to 400%, the slower the convergence of the matrix iteration and the higher you need to calculate x in Mx.


== Usage tips ==
=== Using quality to increase production ===
There are four ways in which quality can increase the output of a single production machine:
* Increasing the quality of the machine itself will improve its base crafting speed.
* Increasing the quality of [[speed module]]s will increase the effect of their speed improvements.
* Increasing the quality of [[productivity module]]s will increase their productivity bonus without reducing crafting speed. Since extra items obtained from the productivity bonus do not take extra time to produce, this will also increase the number of items produced over time.
* Increasing the quality of [[beacon]]s will increase their transmission efficiency. If they contain speed modules, then the effect of these modules is increased.

These four options share a powerful synergy, as they react multiplicatively with one another. This makes it possible to achieve very high production rates with very few machines when compared to only using normal quality items. For example, imagine a setup where [[electronic circuit]]s are made using one [[electromagnetic plant]] with five [[productivity module 3]]s, which is surrounded by 12 [[beacon]]s with two [[speed module 3]]s, each. With normal quality, this will achieve an output rate of almost 45 items per second (almost enough to saturate one non-layered [[express transport belt]]). However, if the electromagnetic plant and all beacons and modules have legendary quality, the output rate becomes slightly more than 600 items per second (enough to saturate two and a half [[turbo transport belt]]s with four layers of items). This is more than 13 times as many items as without quality.

It should be noted that quality beacons are the only one of these factors that may increase energy consumption over time, as the transmission effect is also applied to the energy cost of speed modules. However, this is offset or even negated by the reduced energy consumption of the beacons themselves (which is also affected by quality), especially with high beacon counts wherein the transmission effect is subject to diminishing returns. For speed modules, productivity modules, and the machine itself, only the speed increase, productivity bonus, and base crafting speed are affected, respectively.

The increased transmission effect of high-quality beacons is also notable because unlike when increasing the number of beacons, there are no diminishing returns for increasing their quality (aside from the exponentially increasing cost of producing those higher-quality beacons in the first place). This means that, despite a legendary beacon only being 1.66 times as powerful as a normal-quality beacon, one would need 0.36 times as many legendary beacons as normal ones to achieve the same effect. Aside from making more powerful beacon setups, this can also be used to save space by achieving the same effect with fewer beacons, thereby leaving more room for machines and belts.

Higher-quality machines are also particularly useful for producing quality items as, unlike speed modules, machine quality does not reduce the chance of increasing a product's quality.

=== Using quality to save space ===
Another use for quality is decreasing the amount of buildings needed to perform the same production. This is particularly useful in a [[space platform]], where small, compact designs are rewarded with increased speed, as well as needing fewer rockets to build the platform.

=== Notes ===
* In the below circumstances, quality modules have no useful effects.
** Placed in a [[Rocket silo]]
** Placed in a [[Lab]]
** Placed in a [[Biolab]]
** Fluid recipes (e.g [[holmium solution]])
* [[Barrel]]s cannot accept quality modules, most likely to stop quality upcycling with no loss.
* The [[Kovarex enrichment process]] recipe cannot accept quality modules, most likely to stop quality upcycling with no loss.

== Trivia ==
* Quality is not technically exclusive to player-made entities; Though this does not occur naturally, quality is also allowed on enemies, asteroids, and even the [[player]] character.
** Some enemies with qualities above normal can even be created in regular sandbox gameplay: Big biters, behemoth biters, and big premature wriggler pentapods born from spoiled [[biter egg]]s, [[captive biter spawner]]s, and [[pentapod egg]]s inherit the quality of the spoiled items, with the latter two being possible to craft with quality modules. Furthermore, a starved captured biter spawner will retain its quality upon converting into a hostile biter spawner, with said quality even being inherited by the biters that it will spawn. Should these biters chose to expand, they may also create quality spitters and worms.

{{Languages}}
{{:Infobox:Electromagnetic plant}}
{{Stub}}
{{About/Space age}}
'''Electromagnetic plant''' is an [[assembling machine]] type from [[Fulgora]]{{SA}} that specializes in the production of electronics and electromagnets. Its size is 4×4, has a production speed of 2, a built-in [[productivity]] bonus of +50% and 5 module slots.

It's unique for the built-in productivity bonus, because unlike [[productivity module]]s, this built-in productivity is not restricted to [[Template:IntermediateNav|intermediate products]] only and instead applies to all craftable recipes.

== Recipes ==
These recipes are exclusive to electromagnetic plants:
* {{IconLink|Lightning collector}} {{SA}} only on Fulgora
* {{IconLink|Superconductor}} {{SA}}
* {{IconLink|Electrolyte}} {{SA}}
* {{IconLink|Supercapacitor}} {{SA}}
* {{IconLink|Quantum processor}} {{SA}} only on [[Aquilo]] {{SA}} or a [[space platform]] {{SA}}
* {{IconLink|Electromagnetic science pack}} {{SA}} only on Fulgora
* {{IconLink|Tesla gun}} {{SA}}
* {{IconLink|Tesla ammo}} {{SA}}
* {{IconLink|Tesla turret}} {{SA}}

These recipes can also be used by [[assembling machine]]s, but can benefit from the electromagnetic plant's 50% productivity:

== Trivia ==
* The absolute maximum output rate achievable with a single electromagnetic plant is 301 times the standard output rate of its selected recipe. This is achieved by using a legendary electromagnetic plant with five legendary [[productivity module 3]]s, along with 12 legendary [[beacon]]s with two legendary [[speed module 3]]s each; This gives the electromagnetic plant a crafting speed of 109.5 and a productivity bonus of 175%.

Storage chest

2025-02-23T17:44:13Z

Joeykins: Reworded priority order section

{{Languages}}
{{:Infobox:Storage chest}}

The '''storage chest''' is a large advanced storage item that is part of the [[logistic network]]. [[Logistic robot]]s store any items taken out of the [[Player|player's]] logistic trash slots here, as well as items picked up from [[active provider chest]]s. [[Construction robot]]s will use stored items to repair damaged entities and construct [[ghost]]s, as well as storing items picked up as a result of a [[deconstruction planner|deconstruction order]]; this includes the [[wood]]/[[stone]]/[[coal]] from [[tree]]s & [[rock]]s which were in the way of a ghost placement, and any items in other chests or on belts or inside buildings such as [[assembling machine]]s when they are marked for deconstruction. Storage chests can be filtered to only accept one type of item from the logistic network.

=== Notes ===
* Logistic robots will pick up items in the following priority: [[active provider chest]]s > storage chests, [[buffer chest]]s > [[passive provider chest]]s
* Logistic robots will begin to fill storage chests from active provider chests if there are no other tasks available.
* Logistic robots, and construction robots fulfilling deconstruction orders, will fill storage chests in the following priority:
*# Storage chests with a matching logistics filter and which already contain the item
*# Empty storage chests with a matching logistics filter
*# Unfiltered storage chests which already contain the item
*# Empty and unfiltered storage chests
*# Unfiltered storage chests containing other items
* The filter that can be set on the storage chest is respected even if items that are actively being pushed to the network can not be stored anywhere else.
* If a logistic robot carrying an item is unable to deliver its cargo (e.g. if the player moves out of range), it will drop its cargo in a storage chest before moving to other tasks.

Decider combinator

2024-08-03T13:09:21Z

Joeykins: /* Function */ split input and output headers to different cells for readability

{{Languages}}
{{:Infobox:Decider combinator}}

The Decider combinator is part of the circuit network and one of three types of combinators available in the game (with the other two being the [[constant combinator]] and [[arithmetic combinator]]). It is used to make comparisons of signals on the network. Signals can be compared using the following:

[[File:decider_combinator_anim.png]]

*"is greater than" (>)
*"is less than" (<)
*"greater than or equal to" (>=)
*"less than or equal to" (<=)
*"is equal to" (=)
*"is not equal to" (!=)

As shown in the picture below showing the GUI, the signal on the left is being compared to that of the right.

[[File:decider_combinator_gui.png|350px|GUI of the decider combinator.]]

== Function ==
The internal logic process has three steps:

# Values for each individual input signal(s) (items of the same name) on the red and green wires are summed within the combinator.
# The decider combinator GUI specifies a "first" input signal, a comparison (>, <, =, >=, <=, !=), and a "second" input signal or constant.
# If the comparison returns true, the output is one or more signals with a value of 1 or the unchanged input value(s), or a single signal carrying either a sum of input signals or the number of passed tests. ([[#output_table|see table below]])

The decider combinator can handle [[Circuit network#Logic signals|logic signals]].

Further notes:

* Using the Everything output with "Input count" will pass all non-zero input values to the output as long as the condition is true. Using the Everything output with "1" will output 1 ONLY for all non-zero inputs.
* The Each input will re-apply the comparison for each input signal individually, and will pass the selected output for each input that passes the conditional.
* The Everything input functions as a logical AND, and will return true only if ALL non-zero inputs pass the conditional, and returns true if there are no inputs at all (so "everything ≠ 0" always passes).
* The Anything input functions as a logical OR, and will return true if ANY non-zero input passes the conditional, and returns false if there are no inputs at all (so "anything = 0" always fails). If used for output, Anything will return one of the signals that matched.
* When "Input Count" is selected the output will match the input for the selected signal if the first parameter is not Each. If the first parameter is Each then "Input Count" refers to the value of the input signal that is currently being iterated, so the result will be the sum of all inputs if the output signal is not Each. If the output signal is also Each then every input signal that passes the test is simply forwarded while those that fail the test are discarded.

The following table shows how different combinations of the first input parameter and the output can be used.

Construction robot

Joeykins: /* Mechanics */ have tested construction bots deconstructing items where a requester chest has an open request for said item

{{Languages}}
{{:Infobox:Construction robot}}

'''Construction robots''' are autonomous floating devices capable of repairing or building the [[Player|player's]] structures. They are one of two type of floating robotic devices, the other being the [[logistic robot]]s. They run on electricity from [[roboport]]s, or a [[personal roboport]].
== Mechanics ==

Construction robots accomplish various tasks, including:

* They repair damaged entities using [[Repair pack|repair packs]].
* They replace destroyed entities as long as they are available in a [[provider chest]] or [[storage chest]].
* They remove entities marked with the [[deconstruction planner]]. Removed entities are transported into storage chests; if a [[Requester chest|requester]]/[[Buffer chest|buffer]] chest has an unfulfilled logistics request for the item being deconstructed then construction bots will prioritise placing items directly in to these chests. This includes environmental entities such as [[Raw fish|fish]] and [[Tree|trees]]; [[Cliff|cliffs]] can be "deconstructed" if a construction robot has access to [[Cliff explosives|cliff explosives]] in a provider or storage chest in their network, or in the player's inventory.
* They add entities marked with a [[blueprint]] or placed as [[Ghost|ghosts]] as long as these entities are available. Entities are fetched from the closest logistic chest.
* They can carry and build up to four [[tile|tiles]] at once, depending on the researched [[worker robot cargo size (research)|worker robot cargo size]].

Construction robots have no means of defending themselves and do not run when they encounter enemies. Because they often operate at the "front", they are in high danger to be destroyed. Despite being a floating entity, ground units using melee are still capable of destroying them.

Researching [[Worker robot cargo size (research)|more cargo]] or [[Worker robot speed (research)|more speed]] for the logistic bots are also valid for the construction robots.

Circuit network

2024-03-04T12:39:06Z

Joeykins: /* Devices */ Clarified that Stack Filter Inserter can only filter 1 item at a time, not 5

{{Languages}}
'''Circuit networks''' are built using [[Red wire|red]] or [[green wire]], and enable the control of receivers, based upon information broadcast onto the network by connected senders. Most senders are storage devices, and broadcast their information onto a specific channel, based on the item or liquid the storage device contains. Each circuit network contains a channel for every kind of item, as well as 48 extra [[#Virtual signals|virtual signals]] which act as user-definable channels. 'Everything', 'Anything' and 'Each' are also available wildcards.

[[File:shared_circuit_network.png|thumb|600px|right|Two circuit networks shared over one [[small electric pole]].]]

== Usage ==
=== Send information ===
Senders broadcast the amount of items or fluids they contain or other data definable by the player. Each amount is broadcast as a numeric value on a 'channel' corresponding to the item. For example, a Storage Tank containing 1000 Crude Oil will broadcast 1000 on the Crude Oil channel.

The channels are separated from each other, so each network can simultaneously carry a number for each item and fluid in the game, and for each of the extra user-defined channels (digits 0-9, letters A-Z, and 9 different colors). All unused channels have the value zero.

Multiple broadcasts of the same item or fluid are additive: If there are two connected Storage Tanks with 1000 Crude Oil each, the value of the Crude Oil channel within the network will be 2000.

All wires of the same color which are connected together by junctions form a network, i.e. they will pass their signals to each other. For example, if two red wires are connected to the same combinator input, each wire receives the content from the other. This can result in feedback if care is not taken; see Feedback (under [[#Combinators|arithmetic combinator]], below) for discussion.

Numbers are in the signed 32 bit integer range, i.e. from -2147483648 to 2147483647 inclusive, and are encoded in [https://en.wikipedia.org/wiki/Two%27s_complement two's complement representation]. The numbers wrap around on overflow, so e.g. 2147483647 + 10 becomes -2147483639. When entering a number in a combinator it can appear to exceed the 32 bit limit until the GUI is closed, at which point the number will overflow/underflow. [https://forums.factorio.com/58419]

=== Control devices ===
Receivers can use broadcast information, in most cases to enable/disable the device. They can either compare results between different channels, or compare a channel to a specific value.

Receiving devices sum all signals from each wire connected to them, even red and green wires. For example, if an inserter is connected to a red wire carrying a signal for 20 copper plates and a green wire with 10 copper plates, the input signal set for that receiver will be 30 copper plates.

Multiple wires of the same color will share & sum their signals. For example, 3 chests A, B and C connected in a row (A -> B -> C) with green wire will output the sum of their contents along any green wire connected to any of the chests. However, if a red wire connects chest A to an inserter, that inserter will only be given the contents of A as its input signal.

== Devices ==

Each device that is able to be connected to a circuit network has a [[File:Circuit network panel.png]] icon located in the top right corner of its info pane. Clicking this icon will display the available circuit network options for that device (note: a red or green wire must be connected, otherwise the message "not connected" will display instead). Clicking the [[File:Logistic network panel.png]] icon next to it, the device can be connected to a logistic network if in range of one, which also allows conditions to be set.

Conditions can be set for both circuit (signals of red and green wires are summed) and logistic network, which will together act as a logical AND.

The following devices can be connected to a circuit network:

== Physical network structure ==
A circuit network consists only of those devices connected together with the same color wire. Wire can be strung directly from device to device, or across any intervening power poles. Wire length is limited by its previous connection.

Note that each connected set of wires forms a separate network. For example, it's entirely possible to have four red-wire networks and three green-wire networks. If red and green wires happen to touch the same power pole or device, the red and green networks will remain separate and will not link up. However, two red cables or two green cables will link if they touch. Use different colored cables to separate networks in close proximity.

* To connect wires or cables to a power pole, simply click on one entity, then on the base of the power pole.
* To erase a wire or cable connection, place the same color wire over an existing connection. You don't get the wire/cable back.
* To remove '''all''' connections from a power pole, shift-click on the pole. The first shift-click will remove all electrical connections, and the second will remove all red and green wires. You don't get the wires back.
* When connecting to a [[arithmetic combinator]] or [[decider combinator]], take care to connect the wire to the correct input or output side. Use "Show details" mode to see the orientation of the combinator.
* Hovering the mouse cursor over an item will highlight all wires which connect to the item.
* Hovering the mouse cursor over a power pole which is part of a network will display the signals on its network. Some items like combinators will also display their input and output signals when hovered over.

== Combinators ==
Combinators can function as both receiving and sending devices and allow more advanced functions to be used on a circuit network.

*The [[constant combinator]] broadcasts up to 20 values on any of the channels for whatever networks it is connected to. (You cannot currently specify whether a value should be on the red or green channel; if you need different values, use two combinators, one for each color wire.) You can use any item channel or any of the [[#Virtual signals|virtual signal]] channels.
**Note that using two of the 20 slots to broadcast values on the '''same''' channel is the same as broadcasting the sum of the two values from one slot.
*The [[arithmetic combinator]] performs arithmetic operations on input values and broadcasts the result to the specified output channel. The input and output channels can be any item channel or any of the virtual signal channels.
** Connecting: The arithmetic combinator connects to a red or green network on its '''input''' side (the terminals are set into the main body and look like spark plugs) and performs an arithmetic calculation which is broadcast into the specified channel on its '''output''' side (the output wires appear to stretch out a bit from the body of the device).
** Feedback: Note that the input network and the output network '''are not the same network'''. Connecting the output network back to the input network will result in a feedback loop. For example, adding 1 to the value for copper plates and broadcasting it as copper plates is an action that results in an infinite loop if output is connected back to input. The value for copper plates will rapidly (but not instantly) shoot upward. (The rate at which it climbs is determined by the current tick rate.) This technique can be combined with decider combinator logic to make electronic clocks, gates, and other systems; see [[Tutorial:Combinator tutorial|Combinator Tutorial]] for advanced techniques.
** Each: This combinator can use the 'Each' signal for both input and output, in which case '''all''' non-zero input channels will have the combinator's operation performed and broadcast on the output side. Having Each signals for input and output and using a non-changing operation (like adding zero) is equivalent to having a 'one-way' wire; all the information from the input network is copied to the output network, but the reverse is not true.
**Multi-network: The arithmetic combinator can be joined to both red and green networks on the input side and will sum their inputs.
*The [[decider combinator]] functions much like an arithmetic combinator, but is designed to compare values. Essentially, it is a conditional. In terms of connecting, feedback, and the Each signal it functions as specified above. In addition, it can handle the Everything and Anything signals, and performs more complex functions than summing when attached to multiple networks. See the [[decider combinator]] page for more details on how to use this.

== Virtual signals ==
[[File:Virtual Signals dialog box.png|thumb|Virtual Signals available for use in the circuit network]]
Virtual signals are special non-item signals. Other than the three logic signals, virtual signals do not behave differently from item signals.

48 virtual signals can be sent over a network. They include the digits zero through nine, the letters A through Z, a check-mark, dot and info icon, and the colors red, green, blue, yellow, magenta, cyan, white, gray and black.

=== Logic signals ===
[[File:logic_signals.png|300px|thumb|The icons of the three logic signals]]
Three of the virtual signals cannot be sent over a network but apply special logic to multiple signals.

==== Everything ====
''Everything'' can be used on the left side in conditionals. The condition will be true when the condition is true for each input signal. The condition is also true if there are no signals. This means that the ''everything'' signal behaves as [[:Wikipedia:universal quantification|universal quantification]].

If a signal (rather than a constant number) is used on the right side of the comparison with ''everything'', it is implicitly excluded from the set of signals that ''everything'' checks, so the signal is not matched against itself. That means it is meaningful test e.g. ''everything'' > ''X'', without getting a trivially false result on ''X'' > ''X''.

The output of a [[decider combinator]] may also use ''everything'', unless the input is set to ''each''. When used, the combinator will output signal on every channel with non-zero input as long as the condition is true; the value will either be the input value or 1, depending on the corresponding setting.

==== Anything ====
''Anything'' can be used on the left side of conditions. It will be false when there are no inputs. The condition will be true when the condition is true for at least one signal. This means the ''anything'' signal behaves as [[:Wikipedia:existential quantification|existential quantification]].

If a signal (rather than a constant number) is used on the right side of the comparison with ''anything'', it is implicitly excluded from the set of signals that ''anything'' checks, so the signal is not matched against itself. That means it is meaningful test e.g. ''anything'' >= ''X'', without getting a trivially true result on ''X'' >= ''X''.

When used in both the input and output of a decider combinator, ''anything'' will return one of the signals that matched.

==== Each ====
''Each'' can only be used in left input side and output of [[decider combinator|decider]] and [[arithmetic combinator|arithmetic]] combinators. The signal can only be used as an output when also used as an input. When used in both the input and output, it makes a combinator perform its action on each input signal individually. The combinator will output the sum of each of the actions if only used in the input.

A combinator using ''each'' is like a stack of combinators with all inputs connected and all outputs connected in parallel. For example, if there are signals "copper" and "iron" present, one combinator would be evaluating conditions for copper, and the other combinator would be evaluating conditions for iron. The different output signals would then be added together on the shared wire.

Unlike ''everything'' and ''anything'' above, if a signal is used on the right hand side of an ''each'' operation, it is NOT implicitly excluded. So if you e.g. have ''each'' * ''X'' then you will also get ''X'' multiplied with itself in the output.

Each as an input will only be processed on signals that have a non-zero value. If you have a [[decider combinator|decider]] condition that inputs and output each, but wants to output only one value for an input signal that passes the condition, it will never output 1 for a signal which has a zero value, even if the condition is one that would be passed for a zero value.

*'''[[Tutorial:Circuit network cookbook]]''' - ''Example-heavy tutorials; for beginners who want to get to know and use the benefits of the circuit network.''
*'''[[Tutorial:Combinator tutorial]]''' - ''Mainly textual and detailed tutorials.''

== Logistic network ==
The logistic network used by [[logistic robot]]s is essentially a third network (a wireless one), along with the green and red wired networks. The logistic network is based on coverage by [[roboport]]s.

Some devices can also be connected to the logistic network and enabled based on a condition. If a device has conditions set for circuit and for logistic network, it will become activated if both conditions are true. Devices that can also be controlled with the logistic network:
* Transport belts
* Inserters
* Train stop
* Mining drills
* Pumpjack
* Power switch
* Lamp
* Offshore pump
* Pump

See the [[logistic network]] and [[roboport]] articles for more information.

The '''storage chest''' is a large advanced storage item that is part of the [[logistic network]]. [[Logistic robot]]s store any items taken out of the [[Player|player's]] logistic trash slots here, as well as items picked up from [[active provider chest]]s. [[Construction robot]]s will use stored items to repair damaged entities and construct [[ghost]]s, as well as storing items picked up as a result of a deconstruction order; this includes the wood/stone/coal from trees & rocks which were in the way of a ghost placement, and any items in other chests or on belts or inside buidings such as assembly machines when they are marked for deconstruction. Storage chests can be filtered to only accept one type of item from the logistic network.

=== Notes ===
* Logistic robots will pick up items in the following priority: [[active provider chest]]s > storage chests, [[buffer chest]]s > [[passive provider chest]]s
* Logistic robots will begin to fill storage chests from active provider chests if there are no other tasks available.
* Logistic robots, and construction robots fulfilling deconstruction orders, will fill storage chests in the following priority:
*# Storage chests with a matching inventory
*# Storage chests with a matching filter
*# Storage chests with no filter and no inventory
*# Storage chests with no filter and a mismatched inventory
* The filter that can be set on the storage chest is respected even if items that are actively being pushed to the network can not be stored anywhere else.
* If a logistic robot carrying an item is unable to deliver its cargo (e.g. if the player moves out of range), it will drop its cargo in a storage chest before moving to other tasks.

Personal roboport MK2

2023-12-14T16:54:52Z

Joeykins: Clarified construction area formula for mixed MK2 & MK1 equipment

{{Languages}}
{{:Infobox:Personal roboport MK2}}
The '''personal roboport MK2''' allows construction bots to work from the [[player|player's]] inventory. The personal roboport MK2 supports significantly more robots than the [[personal roboport]] (25, versus 10 for the MK1), a larger construction area (40×40 rather than 30×30), and extra charging ports (4 instead of 2). Inserting multiple of either roboport into the player's [[modular armor]] or the [[spidertron]] increases the number of supported robots, size of construction area and number of charging ports on a linear scale.

It can be toggled on or off via a button in the [[shortcut bar]]. The roboport's internal energy buffer must be 20% full to allow [[construction robot]]s to deploy. If the personal roboport is disabled via the shortcut bar while any of the player's robots already out of the inventory and performing a task, they will continue to finish their tasks before returning to the player.

If a personal robot runs out of energy it will reduce its speed and continue to try and catch up with the player.

The formula for calculating the total construction area is: 
<code>sqrt((num_mk2roboports x mk2_construction_area) + (num_mk1roboports x mk1_construction_area))</code>. 
For example, 3 MK2 roboports: <code>sqrt(3 x 1600)</code> = 69.282, ie. 69x69; 2 MK2 roboports & 2 MK1 roboports: <code>sqrt(2 x 1600 + 2 x 900)</code> = <code>sqrt(5000)</code> = 70.711, ie 70x70.

{{history|0.17.10|
* "Toggle personal roboport" function is now accessible via keyboard shortcut.}}

{{history|0.17.0|
* Added shortcut bar that allows toggling personal roboport on and off.
* Changed personal roboports so they won't send construction robots if you're driving in a vehicle that they can't keep up with or if in a train in automatic mode.}}
