Basics

Prototype type: fluid

A fluid.

Mandatory properties

Inherits all properties from Prototype.

icons, icon, icon_size (IconSpecification)

Type: Types/IconSpecification

default_temperature

Type: Types/double

Also the minimum temperature of the fluid.

max_temperature

Type: Types/double

base_color

Type: Types/Color

Used by bars that show the fluid color, like the flamethrower turret fill bar in the tooltip, or the fill bar for the fluidwagon tooltip; and for the pipe windows and storage tank fill gauges.

flow_color

Type: Types/Color

Used only for pipe windows or storage tank fill gauges.

pressure_to_speed_ratio

Type: Types/double

flow_to_energy_ratio

Type: Types/double

Flow to energy ratio can't be negative.

Optional properties

heat_capacity

Type: Types/Energy

Default: "1KJ"

Joule needed to heat 1 Unit by 1 °C.

fuel_value

Type: Types/Energy

Default: "0J"

emissions_multiplier

Type: Types/double

Default: 1.0

Scales pollution generated when the fluid is consumed.

subgroup

Type: Types/string

Default: "fluid"

The value of this property may not be an empty string. It either has to be nil, or a non-empty string.

gas_temperature

Type: Types/double

Default: max value of double (1.7976931348623158e+308)

max_push_amount

Type: Types/double

Default: 1

When two fluids interact how much of it can be pushed at most.

ratio_to_push

Type: Types/double

Default: 2.1

How much more height must one fluid have to push the other.

auto_barrel

Type: Types/bool

Whether the fluid should be included in the barrel recipes automatically generated in data-updates.lua in the base mod. Not actually a property of the prototype, so it is discarded by the game when loading finishes.

Example

  {
    type = "fluid",
    name = "water",
    default_temperature = 15,
    max_temperature = 100,
    heat_capacity = "0.2KJ",
    base_color = {r=0, g=0.34, b=0.6},
    flow_color = {r=0.7, g=0.7, b=0.7},
    icon = "__base__/graphics/icons/fluid/water.png",
    icon_size = 32,
    order = "a[fluid]-a[water]",
    pressure_to_speed_ratio = 0.4,
    flow_to_energy_ratio = 0.59
  }
