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 - Display information about the game and customize your experience.
  • Multiplayer - Message filtering, banning users, etc.
  • Scripting/Cheating - Run small Lua scripts (but they disable achievements for the save game)

Using the console

The console display can be toggled with the / (slash) or ~ (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.

The console supports rich text tags. These tags are useful for sharing blueprints, marking map locations in chat or adding icons to map markers and train stations. Ctrl+alt clicking the map or ground will automatically insert a gps tag and post it into the console. Shift clicking most things with the console open will insert a tag for that thing into chat.

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 and keys to scroll through the console history.

Use the and keys to cursor through the currently displayed message or command, which you can edit (delete, insert, etc.) and resend (by pressing Return).

The Tab key will auto-complete commands and player ids.

Scripting and cheat commands

Command Description
/cheat <all> Researches all technologies and enables cheat mode. Using the all option also gives the player some additional items.
/command <command> Executes a Lua command.
/c <command> Executes a Lua command.
/editor Toggles the map editor.
/measured-command <command> Executes a Lua command and measures time it took.
/silent-command <command> Executes a Lua command without printing it to the console.

This is a very powerful feature, which also allows cheating, and as such achievements will be permanently disabled for the save as soon as you use a script command.

Basic example scripts

Use it as calculator

/c game.player.print(1234*5678)

Zoom beyond normal bounds

Note that zooming too far out can cause performance hits. Be careful.

/c game.player.zoom=0.1

Mine faster

/c game.player.force.manual_mining_speed_modifier=1000

Craft faster

/c game.player.force.manual_crafting_speed_modifier=1000

Unlock and research all technologies

/c game.player.force.research_all_technologies()

Undo this with the command in the next section.

Unresearch all technologies

This does not reset manually applied bonuses

/c for _, tech in pairs(game.player.force.technologies) do 
	tech.researched=false
	game.player.force.set_saved_technology_progress(tech, 0)
end

Reset your force

This resets all data for your force, including kill and production statistics, technologies, bonuses and charting status.

/c game.player.force.reset()

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.

/c game.player.game_view_settings.show_rail_block_visualisation = true

Inventory manipulation scripts

Cheat mode

Allows for infinite free crafting. Disable by replacing true with false.

/c game.player.cheat_mode=true

Refill resources (refill oil, iron etc.)

While holding the cursor over a resource tile in-game

/c game.player.selected.amount=7500

Alternatively you can refill all resources in the map with the following command. Change ore.amount to the desired value.

/c surface = game.player.surface
for _, ore in pairs(surface.find_entities_filtered({type="resource"})) do
    ore.amount = 10000
end

Add items to the player's inventory

Replace iron-plate with the internal name of the item desired.

/c game.player.insert{name="iron-plate", count=100}

For instance, here's a stack of the god-mode energy system interface:

/c game.player.insert{name="electric-energy-interface"}

Add a powerful armor with equipment and some tools for construction:

/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}

World manipulation scripts

Reveal the map around the player

Reveals the map around the player, similar to a radar.

/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}})

or from start position

/c game.player.force.chart(game.player.surface, {{x = -2000, y = -2000}, {x = 2000, y = 2000}})

Change 150 to the desired radius, higher values take longer.

Hide revealed map

Hides all revealed chunks, inverted map revealing.

/c local surface = game.player.surface
local force = game.player.force
for chunk in surface.get_chunks() do
  force.unchart_chunk({x = chunk.x, y = chunk.y}, surface)
end

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.

/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

Turn off night

Enables eternal day.

/c game.player.surface.always_day=true

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.

/c game.speed=X

Expensive (marathon) or normal mode

To change from normal to expensive mode preset (this changes the research cost and intermediate product cost):

/c game.difficulty_settings.recipe_difficulty=1
game.difficulty_settings.technology_difficulty=1
game.difficulty_settings.technology_price_multiplier=4

To change back to normal:

/c game.difficulty_settings.recipe_difficulty=0
game.difficulty_settings.technology_difficulty=0
game.difficulty_settings.technology_price_multiplier=1

Freeze time

Stops the advancement of the time if you replace "BOOL" with "true" or unfreezes it if you replace it with "false".

/c game.player.surface.freeze_daytime=BOOL

Remove all pollution

/c game.player.surface.clear_pollution()

Completely turn off pollution

/c for _, surface in pairs(game.surfaces) do
  surface.clear_pollution()
end
game.map_settings.pollution.enabled = false

Add a lot of pollution

/c game.player.surface.pollute(game.player.position, 1000000)

Where speakers are, by who

/c speakers = game.player.surface.find_entities_filtered{force = game.player.force, type="programmable-speaker"}
for key, speaker in pairs(speakers) do
    game.player.print(speaker.last_user.name .. " placed a speaker at X=" .. speaker.position.x .. ", Y=" .. speaker.position.y)
end

Disable friendly fire for your force

/c game.player.force.friendly_fire = false

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".

/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

Remove resources around the player

Removes all resource patches from the ground in a 50 x 50 area around the player.

/c local surface=game.player.surface
local size=50
local pos=game.player.position

for _, e in pairs(surface.find_entities_filtered{area={{pos.x-size, pos.y-size},{pos.x+size, pos.y+size}}, type="resource"}) 
	do e.destroy() 
end

Add new oil patch

This creates 9 crude oil patches in a 3×3 square.

/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

or randomly without any collision:

/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

Create 10 fishes

This creates 10 fishes around of player. The player must be on the water edge.

/c local player = game.player
local surface = player.surface
for i = 1, 10 do
  local position = surface.find_non_colliding_position('fish', player.position, 10, 1)
  if not position then return end
  surface.create_entity {name = 'fish', position = position}
end

Count entities

Counts all entities whose name includes the string in local entity.

/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
	end
end
game.player.print(count)

Emptying all pipes, underground pipes and pumps

Useful when pipes contain a fluid you dont want.

/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")

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.

/c local mgs = game.player.surface.map_gen_settings
mgs.cliff_settings.cliff_elevation_0 = 1024
game.player.surface.map_gen_settings = mgs

Remove all cliffs

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

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

Delete all decoratives

Delete the decoratives that can be found in the world.

/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

Change map generation settings

This allows to change the map generation settings for new chunks; it does not alter already generated 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 resource that should be changed and replace "very-high" with the desired MapGenSize in the following command. Replace "iron-ore" with "enemy-base" to change the enemy base generation settings.

/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

To change water generation settings, replace "very-high" with the desired MapGenSize in the following command.

/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

Enemy/evolution scripts

Set evolution factor

Ranges from 0 (new game) to 1.

/c game.forces["enemy"].evolution_factor=X

Disable time-based evolution & increases pollution-based evolution

/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

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.

/c game.forces["enemy"].kill_all_units()

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. You can prevent biters being on newly generated chunks if desired.

/c local surface=game.player.surface
for key, entity in pairs(surface.find_entities_filtered({force="enemy"})) do
	entity.destroy()
end

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.

/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)

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.

/c game.player.surface.peaceful_mode = true

Enable/Disable biter expansion

Biter expansion allows biters to create new nests, it is enabled by default. Substitute true for false to disable.

/c game.map_settings.enemy_expansion.enabled = true

Prevent biters being on newly generated chunks

On newly generated chunks no biters will be present, however all current biters will remain unaffected. Equivalent of setting the Enemy Base Size to None under the Terrain settings during map generation but achieved mid game by changing map generation settings.

/c local surface = game.player.surface
local mgs = surface.map_gen_settings
mgs.autoplace_controls["enemy-base"].size = "none"
surface.map_gen_settings = mgs

Player character scripts

Commands concerning the player directly.

Get player position

Prints coordinates of your current position.

/c game.player.print(game.player.position.x .. ", " .. game.player.position.y)

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.

/c game.player.teleport({X, Y})

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:

/c game.player.character=nil

Then, hover the mouse over the useless player and destroy it by typing:

/c game.player.selected.destroy()

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.

/c game.player.create_character()

Enable long reach

Enables long reach, which allows the player to build and interact with entities at a greater distance. The default reach is 10.

/c local reach = 10000
game.player.force.character_build_distance_bonus = reach
game.player.force.character_reach_distance_bonus = reach

Research scripts

Enable Research Queue

Enable the research queue for the players current team. Can be done after the game has started if it was forgotten during the map's setup.

/c game.player.force.research_queue_enabled = true

Enable faster research

/c game.player.force.laboratory_speed_modifier=1

1 is normal speed, 2 is double speed 3 is triple etc.

Research specific technologies

The internal technology names can be found in the infoboxes on their respective pages.

/c game.player.force.technologies['electric-energy-distribution-1'].researched=true
/c game.player.force.technologies['steel-processing'].researched=true

Unresearch specific technologies

The internal technology names can be found in the infoboxes on their respective pages.

/c game.player.force.technologies['electric-energy-distribution-1'].researched=false; game.player.force.set_saved_technology_progress('electric-energy-distribution-1', 0)
/c game.player.force.technologies['steel-processing'].researched=false; game.player.force.set_saved_technology_progress('steel-processing', 0)

Enabling specific recipes

The internal recipe/item names can be found in the infoboxes on their respective pages.

/c game.player.force.recipes["electric-energy-interface"].enabled=true
/c game.player.force.recipes["rocket-silo"].enabled=true
/c game.player.force.recipes.loader.enabled=true
/c game.player.force.recipes["fast-loader"].enabled = true
/c game.player.force.recipes["express-loader"].enabled = true

Enable all recipes

/c for name, recipe in pairs(game.player.force.recipes) do recipe.enabled = true end

 --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.

 --map2scenario SAVE

Converts a save game to a User Scenario, allows saved game state to be loaded into map editor. Assuming that save game name is "foo.zip", executing './factorio --map2scenario s1' will result in Factorio loading, opening the save file, and saving the scenario into the scenario folder.
