The abstract basis of the assembling machines and furnaces. Contains the properties that both of them have.

Note that a crafting machine cannot be rotated unless it has at least one of the following: a fluid box, a heat energy source, a fluid energy source, or a non-square collision box. Crafting machines with non-square collision boxes can only be rotated before placement, not after.

Mandatory properties

This prototype inherits all the properties from Prototype/EntityWithHealth.


Type: Energy
Sets how much energy this machine uses while crafting. Energy usage has to be positive.


Type: double
How fast this crafting machine can craft. 1 means that for example a 1 second long recipe take 1 second to craft. 0.5 means it takes 2 seconds, and 2 means it takes 0.5 seconds.

Crafting speed has to be positive.


Type: table of strings
A list of recipe categories this crafting machine can use.


crafting_categories = {"crafting", "smelting"}


Type: EnergySource
Defines how the crafting machine is powered.

When using an electric energy source and drain is not specified, it will be set to energy_usage ÷ 30 automatically.

Optional properties


Type: Animation4Way
The animation played when crafting. When the crafting machine is idle, the animation will be paused.

When a crafting machine cannot be rotated, only the north rotation of the animation will be used.


Type: Animation4Way
The animation played when idle. Idle animation must have the same frame count as animation.

When a crafting machine cannot be rotated, only the north rotation of the idle animation will be used.


Type: table of FluidBox
Can have off_when_no_fluid_recipe key that has a bool value. off_when_no_fluid_recipe defaults to false.

If a crafting machine has fluid boxes and off_when_no_fluid_recipe is true, the crafting machine can only be rotated when a recipe consuming or producing fluid is set, or it has one of the other properties listed at the top of the page.

fluid_boxes =
        production_type = "input",
        pipe_picture = assembler2pipepictures(),
        pipe_covers = pipecoverspictures(),
        base_area = 10,
        base_level = -1,
        pipe_connections = {{ type="input", position = {0, -2} }},
        secondary_draw_orders = { north = -1 }
        production_type = "output",
        pipe_picture = assembler2pipepictures(),
        pipe_covers = pipecoverspictures(),
        base_area = 10,
        base_level = 1,
        pipe_connections = {{ type="output", position = {0, 2} }},
        secondary_draw_orders = { north = -1 }
      off_when_no_fluid_recipe = true


Type: EffectTypeLimitation
Sets the module effects that are allowed to be used on this machine.


Type: bool
Default: false
Whether the "alt-mode icon" should be scaled to the size of the machine.


Type: bool
Default: true
Whether the "alt-mode icon" should be drawn at all.


Type: bool
Default: false


Type: table of Color

crafting_machine_tint = { primary = {r=1,g=1,b=1,a=1}, secondary = {r=1,g=1,b=1,a=1}, tertiary = {r=1,g=1,b=1,a=1}, quaternary = {r=1,g=1,b=1,a=1}}

Each key/value pair is optional and defaults to the above value.


Type: bool
Default: false
Controls whether the ingredients of an in-progress recipe are destroyed when mining the machine/changing the recipe. If set to true, the ingredients do not get destroyed. This affects only the ingredients of the recipe that is currently in progress, so those that visually have already been consumed while their resulting product has not yet been produced.


Type: vector
Default: {0, -0.3} for Prototype/AssemblingMachine and {0, -0.1} for Prototype/Furnace
Shift of the "alt-mode icon" relative to the machine's center.


Type: bool
Default: true
Whether the "alt-mode icon" should have a black background.


Type: bool
Default: false
Whether the speed of the animation and working visualization should be based on the machine's speed (boosted or slowed by modules).


Type: float
Default: 0
Productivity bonus that this machine always has.


Type: ModuleSpecification
The number of module slots in this machine, and their icon positions.

module_specification = {
  module_info_icon_shift = {
  module_slots = 2


Type: table of WorkingVisualisation
