Mandatory properties

This prototype inherits all the properties from Prototype/EntityWithOwner.

energy_source

Type: EnergySource
Must be an electric energy source.

fluid_box

Type: FluidBox
This must have a filter if max_power_output is not defined.

horizontal_animation

Type: Animation

vertical_animation

Type: Animation

effectivity

Type: double
How much energy the generator produces compared to how much energy it consumes. For example, an effectivity of 0.5 means that half of the consumed energy is output as power.

fluid_usage_per_tick

Type: double
The number of fluid units the generator uses per tick.

maximum_temperature

Type: double
Used to calculate the max_power_output if it is not defined and burns_fluid is false. Then, the max power output is (min(fluid_max_temp, maximum_temperature) - fluid_default_temp) × fluid_usage_per_tick × fluid_heat_capacity × effectivity, the fluid is the filter specified on the fluid_box.

The maximum temperature to which the efficiency can increase. At this temperature the generator will run at 100% efficiency. Note: Higher temperature fluid can still be consumed.

Optional properties

smoke

Type: table of SmokeSource
Array of 1 or more smoke sources.

burns_fluid

Type: bool
Default: false
If set to true, the available power output is based on the fuel_value of the fluid. Otherwise, the available power output will be based on the fluid temperature.

scale_fluid_usage

Type: bool
Default: false
Scales the generator's fluid usage to its maximum power output.

Setting this to true prevents the generator from overconsuming fluid, for example when higher than maximum_temperature fluid is fed to the generator.
If scale_fluid_usage is false, the generator consumes the full fluid_usage_per_tick and any of the extra energy in the fluid (in the form of higher temperature) is wasted. The steam engine exhibits this behavior when fed steam from heat exchangers.

destroy_non_fuel_fluid

Type: bool
Default: true
This property is used when:

  • burns_fluid is true and the fluid has a fuel_value of 0
  • or burns_fluid is false and the fluid is at default temperature

In these cases, this property determines whether the fluid should be destroyed, meaning that the fluid is consumed at the rate of fluid_usage_per_tick, without producing any power.

min_perceived_performance

Type: double
Default: 0.25
Animation runs at least this fast. This corresponds to the sound.

performance_to_sound_speedup

Type: double
Default: 0.5

max_power_output

Type: Energy
The power production of the generator is capped to this value. This is also the value that is shown as the maximum power output in the tooltip of the generator.

fluid_box must have a filter if this is not defined.
