Prototype/Fluid
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.
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)
Type: Types/bool
Default: false
Hides the fluid from the signal selection screen.
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.
