Hello, I have only had some small dabbling s with humanoid animation so vehicles is really stumping me at the moment.
I have a prototype tank mesh that can fire in all four directions.
However right now when it moves left or right, the tank does not turn left or right to go that way.
How would i go about implementing that?
this might help a bit:
