LocalisedString :: string or number or boolean or LuaObject or nil or array[string or LocalisedString]

Localised strings are a way to support translation of in-game text. It is an array where the first element is the key and the remaining elements are parameters that will be substituted for placeholders in the template designated by the key.

The key identifies the string template. For example, "gui-alert-tooltip.attack" (for the template "__1__ objects are being damaged"; see the file data/core/locale/en.cfg).

The template can contain placeholders such as __1__ or __2__. These will be replaced by the respective parameter in the LocalisedString. The parameters themselves can be other localised strings, which will be processed recursively in the same fashion. Localised strings can not be recursed deeper than 20 levels and can not have more than 20 parameters.

There are two special flags for the localised string, indicated by the key being a particular string. First, if the key is the empty string (""), then all parameters will be concatenanted (after processing, if any are localised strings themselves). Second, if the key is a question mark ("?"), then the first valid parameter will be used. A parameter can be invalid if its name doesn't match any string template. If no parameters are valid, the last one is returned. This is useful to implement a fallback for missing locale templates.

Furthermore, when an API function expects a localised string, it will also accept a regular string (i.e. not a table) which will not be translated, as well as a number, boolean or nil, which will be converted to their textual representation.

Examples

In the English translation, this will print "No ammo"; in the Czech translation, it will print "Bez munice":

game.player.print({"description.no-ammo"})

The description.no-ammo template contains no placeholders, so no further parameters are necessary.

In the English translation, this will print "Durability: 5/9"; in the Japanese one, it will print "耐久度: 5/9":

game.player.print({"description.durability", 5, 9})

This will print "hello" in all translations:

game.player.print({"", "hello"})

This will print "Iron plate: 60" in the English translation and "Eisenplatte: 60" in the German translation.

game.print({"", {"item-name.iron-plate"}, ": ", 60})

As an example of a localised string with fallback, consider this:

{"?", {"", {"entity-description.furnace"}, "\n"}, {"item-description.furnace"}, "optional fallback"}

If entity-description.furnace exists, it is concatenated with "\n" and returned. Otherwise, if item-description.furnace exists, it is returned as-is. Otherwise, "optional fallback" is returned. If this value wasn't specified, the translation result would be "Unknown key: 'item-description.furnace'".


DisplayResolution :: table

Table fields

width :: uint
height :: uint

LogisticParameters :: table

Table fields

name :: string?

The item. nil clears the filter.

The item. nil clears the filter.

min :: uint?
max :: uint?

RealOrientation :: float

The smooth orientation. It is a float in the range [0, 1) that covers a full circle, starting at the top and going clockwise. This means a value of 0 indicates "north", a value of 0.5 indicates "south".

For example then, a value of 0.625 would indicate "south-west", and a value of 0.875 would indicate "north-west".


MapPosition :: table or tuple

Coordinates on a surface, for example of an entity. MapPositions may be specified either as a dictionary with x, y as keys, or simply as an array with two elements.

The coordinates are saved as a fixed-size 32 bit integer, with 8 bits reserved for decimal precision, meaning the smallest value step is 1/2^8 = 0.00390625 tiles.

Table fields

x :: double
y :: double

Examples

Explicit definition:

{x = 5.5, y = 2}
{y = 2.25, x = 5.125}

Shorthand:

{1.625, 2.375}

ChunkPosition :: table or tuple

Coordinates of a chunk in a LuaSurface where each integer x/y represents a different chunk. This uses the same format as MapPosition, meaning it can be specified either with or without explicit keys. A MapPosition can be translated to a ChunkPosition by dividing the x/y values by 32.

Table fields

x :: int
y :: int

TilePosition :: table or tuple

Coordinates of a tile on a LuaSurface where each integer x/y represents a different tile. This uses the same format as MapPosition, except it rounds any non-integer x/y down to whole numbers. It can be specified either with or without explicit keys.

Table fields

x :: int
y :: int

EquipmentPosition :: table or tuple

Position inside an equipment grid. This uses the same format as MapPosition, meaning it can be specified either with or without explicit keys.

Table fields

x :: int
y :: int

Examples

Explicit definition:

{x = 5, y = 2}
{y = 2, x = 5}

Shorthand:

{1, 2}

GuiLocation :: table or tuple

Screen coordinates of a GUI element in a LuaGui. This uses the same format as TilePosition, meaning it can be specified either with or without explicit keys.

Table fields

x :: int
y :: int

ChunkPositionAndArea :: table

A ChunkPosition with an added bounding box for the area of the chunk.

Table fields

x :: int
y :: int
area :: BoundingBox

EquipmentPoint :: table

A table used to define a manual shape for a piece of equipment.

Table fields

x :: uint
y :: uint

GuiAnchor :: table

Table fields

gui :: defines.relative_gui_type
position :: defines.relative_gui_position
type :: string?

If provided, only anchors the GUI element when the opened things type matches the type.

If provided, only anchors the GUI element when the opened things type matches the type.

name :: string?

If provided, only anchors the GUI element when the opened thing matches the name. name takes precedence over names.

If provided, only anchors the GUI element when the opened thing matches the name. name takes precedence over names.

names :: array[string]?

If provided, only anchors the GUI element when the opened thing matches one of the names. When reading an anchor, names is always populated.

If provided, only anchors the GUI element when the opened thing matches one of the names. When reading an anchor, names is always populated.


TabAndContent :: table

Table fields

tab :: LuaGuiElement
content :: LuaGuiElement

OldTileAndPosition :: table

Table fields

old_tile :: LuaTilePrototype
position :: TilePosition

Tags :: dictionary[string → AnyBasic]

A dictionary of string to the four basic Lua types: string, boolean, number, table.

Note that the API returns tags as a simple table, meaning any modifications to it will not propagate back to the game. Thus, to modify a set of tags, the whole table needs to be written back to the respective property.

Example

{a = 1, b = true, c = "three", d = {e = "f"}}

SmokeSource :: table

Table fields

name :: string
frequency :: double
offset :: double
position :: Vector?
north_position :: Vector?
east_position :: Vector?
south_position :: Vector?
west_position :: Vector?
deviation :: MapPosition?
starting_frame_speed :: uint16
starting_frame_speed_deviation :: double
starting_frame :: uint16
starting_frame_deviation :: double
slow_down_factor :: uint8
height :: float
height_deviation :: float
starting_vertical_speed :: float
starting_vertical_speed_deviation :: float
vertical_speed_slowdown :: float

Note

The vectors for all 5 position attributes are a table with x and y keys instead of an array.


Vector :: table or tuple

A vector is a two-element array containing the x and y components. In some specific cases, the vector is a table with x and y keys instead, which the documentation will point out.

Table fields

x :: float
y :: float

Example

right = {1.0, 0.0}

BoundingBox :: table or tuple

Two positions, specifying the top-left and bottom-right corner of the box respectively. Like with MapPosition, the names of the members may be omitted. When read from the game, the third member orientation is present if it is non-zero, however it is ignored when provided to the game.

Table fields

left_top :: MapPosition
right_bottom :: MapPosition
orientation :: RealOrientation?

Examples

Explicit definition:

{left_top = {x = -2, y = -3}, right_bottom = {x = 5, y = 8}}

Shorthand:

{{-2, -3}, {5, 8}}

ScriptArea :: table

An area defined using the map editor.

Table fields

area :: BoundingBox
name :: string
color :: Color
id :: uint

ScriptPosition :: table

A position defined using the map editor.

Table fields

position :: MapPosition
name :: string
color :: Color
id :: uint

Color :: table or tuple

Red, green, blue and alpha values, all in range [0, 1] or all in range [0, 255] if any value is > 1. All values here are optional. Color channels default to 0, the alpha channel defaults to 1.

Similar to MapPosition, Color allows the short-hand notation of passing an array of exactly 3 or 4 numbers. The game usually expects colors to be in pre-multiplied form (color channels are pre-multiplied by alpha).

Table fields

r :: float?
g :: float?
b :: float?
a :: float?

Example

red1 = {r = 0.5, g = 0, b = 0, a = 0.5}  -- Half-opacity red
red2 = {r = 0.5, a = 0.5}                -- Same color as red1
black = {}                               -- All channels omitted: black
red1_short = {0.5, 0, 0, 0.5}            -- Same color as red1 in short-hand notation

ColorModifier :: table or tuple

Same as Color, but red, green, blue and alpha values can be any floating point number, without any special handling of the range [1, 255].

Table fields

r :: float?
g :: float?
b :: float?
a :: float?

AutoplaceControl :: table

Table fields

frequency :: MapGenSize

For things that are placed as spots such as ores and enemy bases, frequency is generally proportional to number of spots placed per unit area. For continuous features such as forests, frequency is how compressed the probability function is over distance, i.e. the inverse of 'scale' (similar to terrain_segmentation). When the LuaAutoplaceControlPrototype is of the category "terrain", then scale is shown in the map generator GUI instead of frequency.

size :: MapGenSize

For things that are placed as spots, size is proportional to the area of each spot. For continuous features, size affects how much of the map is covered with the thing, and is called 'coverage' in the GUI.

richness :: MapGenSize

Has different effects for different things, but generally affects the 'health' or density of a thing that is placed without affecting where it is placed. For trees, richness affects tree health. For ores, richness multiplies the amount of ore at any given tile in a patch. Metadata about autoplace controls (such as whether or not 'richness' does anything for them) can be found in the LuaAutoplaceControlPrototype by looking up game.autoplace_control_prototypes[(control prototype name)], e.g. game.autoplace_control_prototypes["enemy-base"].richness is false, because enemy base autoplacement doesn't use richness.

Whether missing autoplace names for this type should be default enabled.

settings :: dictionary[string → AutoplaceControl]

CliffPlacementSettings :: table

Table fields

name :: string

Name of the cliff prototype.

Name of the cliff prototype.

cliff_elevation_0 :: float

Elevation at which the first row of cliffs is placed. The default is 10, and this cannot be set from the map generation GUI.

Elevation at which the first row of cliffs is placed. The default is 10, and this cannot be set from the map generation GUI.

cliff_elevation_interval :: float

Elevation difference between successive rows of cliffs. This is inversely proportional to 'frequency' in the map generation GUI. Specifically, when set from the GUI the value is 40 / frequency.

Elevation difference between successive rows of cliffs. This is inversely proportional to 'frequency' in the map generation GUI. Specifically, when set from the GUI the value is 40 / frequency.

richness :: MapGenSize

Corresponds to 'continuity' in the GUI. This value is not used directly, but is used by the 'cliffiness' noise expression, which in combination with elevation and the two cliff elevation properties drives cliff placement (cliffs are placed when elevation crosses the elevation contours defined by cliff_elevation_0 and cliff_elevation_interval when 'cliffiness' is greater than 0.5). The default 'cliffiness' expression interprets this value such that larger values result in longer unbroken walls of cliffs, and smaller values (between 0 and 1) result in larger gaps in cliff walls.

MapGenSettings :: table

The 'map type' dropdown in the map generation GUI is actually a selector for elevation generator. The base game sets property_expression_names.elevation to "0_16-elevation" to reproduce terrain from 0.16 or to "0_17-island" for the island preset. If generators are available for other properties, the 'map type' dropdown in the GUI will be renamed to 'elevation' and shown along with selectors for the other selectable properties.

Table fields

terrain_segmentation :: MapGenSize

The inverse of 'water scale' in the map generator GUI. Lower terrain_segmentation increases the scale of elevation features (lakes, continents, etc). This behavior can be overridden with alternate elevation generators (see property_expression_names, below).

water :: MapGenSize

The equivalent to 'water coverage' in the map generator GUI. Specifically, when this value is non-zero, water_level = 10 * log2 (the value of this field), and the elevation generator subtracts water level from elevation before adding starting lakes. If water is set to 'none', elevation is clamped to a small positive value before adding starting lakes. This behavior can be overridden with alternate elevation generators (see property_expression_names, below).

Positions of the starting areas.

Positions of the starting areas.

peaceful_mode :: boolean

Whether peaceful mode is enabled for this map.

Whether peaceful mode is enabled for this map.

property_expression_names :: dictionary[string → string]

Overrides for tile property value generators. Values either name a NamedNoiseExpression or can be literal numbers, stored as strings (e.g. "5"). All other controls can be overridden by a property expression names. Notable properties:
- moisture - a value between 0 and 1 that determines whether a tile becomes sandy (low moisture) or grassy (high moisture).
- aux - a value between 0 and 1 that determines whether low-moisture tiles become sand or red desert.
- temperature - provides a value (vaguely representing degrees Celsius, varying between -20 and 50) that is used (together with moisture and aux) as part of tree and decorative placement.
- elevation - tiles values less than zero become water. Cliffs are placed along certain contours according to CliffPlacementSettings.
- cliffiness - determines whether (when >0.5) or not (when <0.5) a cliff will be placed at an otherwise suitable (according to CliffPlacementSettings) location.
- enemy-base-intensity - a number that is referenced by both enemy-base-frequency and enemy-base-radius. i.e. if this is overridden, enemy base frequency and size will both be affected and do something reasonable. By default, this expression returns a value proportional to distance from any starting point, clamped at about 7.
- enemy-base-frequency - a number representing average number of enemy bases per tile for a region, by default in terms of enemy-base-intensity.
- enemy-base-radius - a number representing the radius of an enemy base, if one were to be placed on the given tile, by default proportional to a constant plus enemy-base-intensity. Climate controls ('Moisture' and 'Terrain type' at the bottom of the Terrain tab in the map generator GUI) don't have their own dedicated structures in MapGenSettings. Instead, their values are stored as property expression overrides with long names:
- control-setting:moisture:frequency:multiplier - frequency (inverse of scale) multiplier for moisture noise. Default is 1.
- control-setting:moisture:bias - global bias for moisture (which normally varies between 0 and 1). Default is 0.
- control-setting:aux:frequency:multiplier - frequency (inverse of scale) multiplier for aux (called 'terrain type' in the GUI) noise. Default is 1.
- control-setting:aux:bias - global bias for aux/terrain type (which normally varies between 0 and 1). Default is 0. All other MapGenSettings feed into named noise expressions, and therefore placement can be overridden by including the name of a property in this dictionary. The probability and richness functions for placing specific tiles, entities, and decoratives can be overridden by including an entry named {tile|entity|decorative}:(prototype name):{probability|richness}.

Examples

Assuming a NamedNoiseExpression with the name "my-alternate-grass1-probability" is defined

local surface = game.player.surface
local mgs = surface.map_gen_settings
mgs.property_expression_names["tile:grass1:probability"] = "my-alternate-grass1-probability"
surface.map_gen_settings = mgs

would override the probability of grass1 being placed at any given point on the current surface.

To make there be no deep water on (newly generated chunks) a surface:

local surface = game.player.surface
local mgs = surface.map_gen_settings
mgs.property_expression_names["tile:deepwater:probability"] = -1000
surface.map_gen_settings = mgs

This does not require a NamedNoiseExpression to be defined, since literal numbers (and strings naming literal numbers, e.g. "123") are understood to stand for constant value expressions.

If the entity does not have a map_color set, this flag makes the entity appear on the map with the default color specified by the UtilityConstants.

"building-direction-8-way"

Uses 45 degree angle increments when selecting direction.

"filter-directions"

Used to automatically detect the proper direction of the entity if possible. Used by the pump, train stop, and train signal by default.

"fast-replaceable-no-build-while-moving"

Prevents inserters and loaders from inserting items into this entity.

"no-copy-paste"

Prevents the entity from being copy-pasted.

"not-upgradable"

Prevents the entity from being selected by the upgrade planner.

"not-in-kill-statistics"

Prevents the entity from being shown in the kill statistics.

"not-in-made-in"

"can-extend-inventory"

Makes the item act as an extension to the inventory that it is placed in. Only has an effect for items with inventory.

"primary-place-result"

Makes construction bots prefer this item when building the entity specified by its place_result.

"mod-openable"

Allows the item to be opened by the player, firing the on_mod_item_opened event. Only has an effect for selection tool items.

"only-in-cursor"

Makes it so the item is deleted when clearing the cursor, instead of being put into the player's inventory. The copy-paste tools use this by default, for example.

"spawnable"

Allows the item to be spawned by a quickbar shortcut or custom input.

CollisionMaskLayer
"not-colliding-with-itself"

Any two entities that both have this option enabled on their prototype and have an identical collision mask layers list will not collide. Other collision mask options are not included in the identical layer list check. This does mean that two different prototypes with the same collision mask layers and this option enabled will not collide.

"consider-tile-transitions"

Uses the prototypes position rather than its collision box when doing collision checks with tile prototypes. Allows the prototype to overlap colliding tiles up until its center point. This is only respected for character movement and cars driven by players.

"colliding-with-tiles-only"

Any prototype with this collision option will only be checked for collision with other prototype's collision masks if they are a tile.
