This engine has three triggers as input and two Boolean values as output. The isOn output is a switch that can be turned on or off by triggering the corresponding input. You can toggle the value by triggering the toggle input. By default isOn is FALSE. The isOff output value is the inverse of isOn


SoSFTrigger on
Turn the isOn switch on.

SoSFTrigger off
Turn the isOn switch off.

SoSFTrigger toggle
Toggle the switch value.


(SoSFBool) isOn
Switch value.

(SoSFBool) isOff
The inverse of isOn.
