Usage in base

Mandatory properties

This prototype inherits all the properties from Prototype/EntityWithOwner.


Type: EnergySource
The capacity of the energy source buffer specifies the capacity of the accumulator. Must be an electric energy source.


Type: Sprite


Type: uint16
Count of ticks to preserve the animation even when the charging ends. Used to prevent rapid blinking of the accumulator with unstable need to use it.


Type: uint16
How long (in ticks) the animation will last after discharge has been initialized.

Optional properties


Type: Animation


Type: LightDefinition
Note that some kind of charge_animation must also be defined for the light to appear.


Type: Animation


Type: LightDefinition
Note that some kind of discharge_animation must also be defined for the light to appear.


Type: WireConnectionPoint
Defines how wires visually connect to this accumulator.


Type: double
Default: 0
The maximum circuit wire distance for this entity.


Type: bool
Default: true


Type: bool
Default: true


Type: CircuitConnectorSprites
The pictures displayed for circuit connections to this accumulator.


Type: SignalIDConnector
The name of the signal that is the default for when an accumulator is connected to the circuit network.
