Prototype/Fluid

Template:Prototype parent A fluid.

Mandatory properties

Inherits all properties from PrototypeBase.

Template:Prototype property Also the minimum temperature of the fluid.

Template:Prototype property 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.

Template:Prototype property Used only for pipe windows or storage tank fill gauges.

Optional properties

Template:Prototype property Joule needed to heat 1 Unit by 1 °C.

Template:Prototype property Scales pollution generated when the fluid is consumed.

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

Template:Prototype property Above this temperature the gas_flow animation is used to display the fluid inside storage tanks and pipes.

Template:Prototype property Hides the fluid from the signal selection screen.

Custom properties

The base mod reads the following property in data-updates.lua to determine if the fluid should be barreled. The property itself is not read by the C++ part of the game which means that it is discarded by the game when loading finishes.

• auto_barrel - bool - Optional, defaults to true. Whether the fluid should be included in the barrel recipes automatically generated in data-updates.lua in the base mod.

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
