Rotate Vehicle??

[Yue]

I have a vehicle that is made up of several joints, sliders and hinges. 

I don't know how to turn the vehicle, i.e. by script, change its angle on its Y-axis, or change its initial position.  If I try it like I really did with SetPosition, or SetRotation, I don't get the results I expected. 

That is, I can only mark its position and initial angle using the map editor, but I can't do it by script.

Here Script vehicle System.

Maybe you need to move the vehicle and all tires?

The new car looks a million times better, by the way.

I have tried to move the tires and the whole vehicle, but the tires for example rotate relative to their local coordinate and not relative to the vehicle.

You always get better at something, over and over again practicing you always see something more beautiful.
