Types/FluidBox

Basics

Visual representation of base_area, base_level and height. When all the fluidboxes are connected, the water leaves fluidbox A and flows into the other 3 boxes through fluidbox B until the water level is equal in all boxes. For more info about fluids, see Fluid system#See also.

Used to set the fluid amount an entity can hold, as well as the connection points for pipes leading into and out of the entity.

for each entity,they may have mutiple fluid box, it can come from both energy source,crafting machines` fluidboxes or just normal property storage tank and pumps etc.

for each fluidbox,it should only storage ONE type of fluid at time, but it do storage mutiple fluid(call fluid mixing,a forbidden technique), to avoid fluid mixing,you can setting up filter for certain fluid, or it is a crafting machine that will automatically disable unused fluid box.

for each fluidbox,it may have mutiple connection point(shown as blue arrow in alt mode,some entity won`t display its connection point tho), fluid may flow in or out depanding on connection point setting, and connection point may depand on direction this entity currently facing,which will be defined as a table of connections.

Mandatory properties

pipe_connections

Type: Types/table of Types/PipeConnectionDefinition

Max number of members is 255.

Optional properties

base_area

Type: Types/double

Default: 1

Must be greater than 0.

base_level

Type: Types/double

Default: 0

height

Type: Types/double

Default: 1

Must be greater than 0.

filter

Type: Types/string

Name of a Prototype/Fluid. Can be used to specify which fluid is allowed to enter this fluid box. [1]

render_layer

Type: Types/RenderLayer

Default: "object"

pipe_covers

Type: Types/Sprite4Way

The pictures to show when another fluid box connects to this one.

pipe_picture

Type: Types/Sprite4Way

minimum_temperature

Type: Types/double

The minimum temperature allowed into the fluidbox. Only applied if a filter is specified [2].

minimum_temperature = 100.0

maximum_temperature

Type: Types/double

The maximum temperature allowed into the fluidbox. Only applied if a filter is specified [3].

maximum_temperature = 1000.0

production_type

Type: Types/string

Default: "None"

Possible values:

• "None"
• "input"
• "input-output"
• "output"

secondary_draw_order

Type: Types/int8

Default: 1

Set the secondary draw order for all orientations. Used to determine render order for sprites with the same render_layer in the same position. Sprites with a higher secondary_draw_order are drawn on top.

secondary_draw_orders

Type: Types/table of Types/int8

Default: {north = 1, east = 1, south = 1, west = 1}

Set the secondary draw order for each orientation. Used to determine render order for sprites with the same render_layer in the same position. Sprites with a higher secondary_draw_order are drawn on top.

Example

fluid_box =
    {
      base_area = 1,
      height = 2,
      base_level = -1,
      pipe_covers = pipecoverspictures(),
      pipe_connections =
      {
        {type = "input-output", position = {-2, 0.5}},
        {type = "input-output", position = {2, 0.5}}
      },
      production_type = "input-output"
    },
