factorio-blueprint

Import and Export blueprint strings automagically with this handy dandy blueprint API

Getting Started

npm install --save factorio-blueprint

Blueprint

Properties

bp.icons

Array of names of entities. No more than four icons are allowed. If this array is empty when calling .luaString(), two icons will be automatically generated.

bp.entities

List of all entities

bp.name

Name of the blueprint, can be set. Be wary of setting this to anything other than letters or numbers.

Methods

Blueprint.getBook(str)

Returns blueprint book (i.e. map (blueprint name) -> (Blueprint object)) for a given blueprint string

Blueprint([data])

Create an empty blueprint. Optional data can be a blueprint string or a Factorio blueprint object

bp.load(data, opt)

Loads blueprint from a blueprint string or a Factorio blueprint object data. Returns self. Options are (all default false):

• allowOverlap: Throws an error if two entities are colliding
• fixEntityData: Automatically adds unknown entities to entityData

bp.toString()

Outputs fancy format with all the entities.

bp.createEntity(name, position, direction=0, allowOverlap=false, noPlace=false, center=false)

Creates an entity of type name at position (top-left corner) facing direction.

• Use allowOverlap to ignore two entities overlapping (which Factorio does not like...)
• Use noPlace if you want the entity to be created but not placed (mainly used in .load())
• Use center if you want position to refer to the center of the entity (again, mainly used by .load())

Returns the new entity

bp.createEntityWithData(data, allowOverlap=false, noPlace=false, center=false)

Creates an entity with loaded data (containing keys such as name, position, direction, recipe, filters, and other options).

Typically used when generating entities from a blueprint string. Can be used to clone an entity using the data of entityToClone.getData()

bp.createTile(name, position)

Creates a tile of type name at position.

Returns the new tile

bp.placeBlueprint(otherBlueprint, position, direction=0, allowOverlap=false)

Places otherBlueprint at position (being the center of otherBlueprint) with rotations direction (0, 1, 2, or 3 rotating clockwise each time). allowOverlap works the same as in createEntity(). Clones both entities and tiles.

Returns self.

bp.findEntity(position)

Return entity that overlaps position or null.

bp.findTile(position)

Return tile at position or null.

bp.removeEntity(entity)

Removes entity, returns it (or false if it was not removed)

bp.removeTile(tile)

Removes tile, returns it (or false if it was not removed)

bp.removeEntityAtPosition(position)

Removes an entity that overlaps position, returns the entity (or false if it was not removed)

bp.removeTileAtPosition(position)

Removes a tile at position, returns the entity (or false if it was not removed)

bp.setIds()

Initialize the IDs on each item. They default to -1, but this is called automatically for things like .toString() and .encode(). Returns self.

bp.fixCenter([point])

Centers all entities on the blueprint. I recommend calling this before Blueprint.encode(). An optional point may be provided to center about.

Returns self.

bp.center()

Get position that is the center of all entities

bp.topLeft()

Get top-left-most entity's corner position

bp.topRight()

Get top-right-most entity's corner position

bp.bottomLeft()

Get bottom-left-most entity's corner position

bp.bottomRight()

Get bottom-right-most entity's corner position

bp.generateIcon(num)

Generate icons based off the entities, num is the number of icons from 1 to 4. Returns self.

bp.toObject()

Object containing all the data (just before being converted to JSON)

bp.toJSON()

Get the JSON data of the blueprint before it's encoded

bp.encode()

Get the encoded blueprint string

static setEntityData(data)

Pass it extra items in the data object if you need custom entities (such as from mods or entities that aren't included). Use the same format as defaultentities.js

static Blueprint.getEntityData()

Get a list of all entities added to be supported by factorio-blueprint.

Entity

Properties

entity.id

1-based index of entity in bp.entities when bp.setIds() is called.

entity.bp

Get the entity's blueprint parent

entity.name

entity.position

entity.size

x/y contain the width/height

entity.direction

Number from 0 to 7. For most things it's 0, 2, 4, or 6

entity.connections

List of wire connections with other entities

entity.condition

Condition if the entity is a combinator

entity.filters

Object of filters. Keys are the positions (1 to X). Used for constant combinators and storage containers.

entity.recipe

Entity name of the recipe

entity.directionType

"input" or "output" to distinguish between ins and outs of underground belts

entity.bar

How many slots have not been blocked off (0 for all slots blocked off, 1 for all but one, -1 for none). Can be up to entity.INVENTORY_SIZE

entity.INVENTORY_SIZE

Number of slots this entity has

Methods

entity.toString()

Fancy display for data about the entity

entity.remove()

Removes self from blueprint

entity.topLeft(), entity.topRight(), entity.bottomLeft(), entity.bottomRight(), entity.center()

Gets position of respective relative location. entity.topLeft() simply returns a clone of the entity's position.
