You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Keep it simple and clear!
I want to make the car drift when you press shift with body movers. Please help me out because I can’t find anywhere on how to.
I don’t think you should use body movers. I think what you want is a hand brake. Just have a button that prevents the back wheels from turning, which should cause the rear end to swing out more. if your game is more arcade-y you can also reduce the friction of the back wheels.
if the car is a manual you could also add a clutch for clutch kicking. but im guessing youre going for a more arcade type car
