Member Function Documentation
◆ Initialize()
|
overridevirtual |
Initialize this vehicle at the specified global location and orientation.
This base class implementation only initializes the main chassis subsystem. Derived classes must extend this function to initialize all other tracked vehicle subsystems (the two track assemblies and the driveline).
- Parameters
-
[in] chassisPos initial global position and orientation [in] chassisFwdVel initial chassis forward velocity
