Hi,
Good point, I think people where using SetProperty to access motorTorque and SteerAngle, but that's sub optimal.
I made the necessary actions on the ecosystem:
SetWheelColliderMotorTorque
setWheelColliderSteerAngle
I also made
GetWheelColliderRpm
use WheelColliderGetWorldPose ( Unity 5 and up) to get the wheel position and rotations and apply it to your visual wheel.
Let me know if all goes well.
Bye,
Jean
