- Target Entity Name
(target)<targetname> - Name of the entity whose velocity will be sensed.
- Measurement Axis
(axis)<vector> - Defines a vector originating from the entity. If the measured entity moves at speed x in exactly this direction, the point_velocitysensor will output x in it's Velocity output. The magnitude of this vector is irrelevant to the calculation.
- Start Enabled
(enabled)<boolean> - Whether or not to start enabled and active.
Inputs
Enable- Enable the sensor.
Disable- Disable the sensor.
