Vehicle Throttle

Type: Action
Category: VEHICLE

Applies engine force to the vehicle's driven wheels. Requires Vehicle Setup to have run first.

Properties

Property	Default	Description
Force	500.0	Engine force (positive = forward, negative = reverse)
Drive	RWD	Drive type: AWD (all wheels), RWD (rear), FWD (front)

Sockets

Socket	Direction	Type
In	Input	Exec
Force	Input	Data (Float)
Out	Output	Exec

Generated code

# Drive = RWD
if hasattr(self, '_vehicle'):
    for _ti in [2, 3]:
        if _ti < self._vehicle.getNumWheels():
            self._vehicle.applyEngineForce(500.0, _ti)

Typical usage

Acceleration with W

[On Key Press: Key=W, Mode=HELD]
    → [Vehicle Throttle: Force=800, Drive=RWD]

[On Key Press: Key=S, Mode=HELD]
    → [Vehicle Throttle: Force=-400, Drive=RWD]

Variable force (gamepad axis)

[On Update]
    → [Vehicle Throttle:
           Force={Math: {Gamepad Axis: Axis=Left Y} * 800.0}
           Drive=AWD]

Notes

• Negative values apply force in reverse.
• Use Vehicle Brake to stop rather than applying negative force.
• Applying 0.0 force removes acceleration without braking.
