Hi, so I'm attempting to create a very simple rigidbody based car in unity, without the physx wheel colliders. What I have right now, is a box with a collider and rigidbody, with 4 cylinder colliders as wheels. I simply use addforce to propel the car and that seems to work fine. Next, I added some raycasts to the base of the two front wheels, so that it can detect if there's an object in front of them, which tells the game to add some force upwards to the front of the car, to try to help it climb over whatever the obstacle is in front of it (assuming it isn't too high.) Am I on the right track here? Another thing I wanted to ask is, how do I get the wheels to rotate correctly? I definitely don't need this car to be super realistic by any means, but I at least want the wheels to rotate proportionally to the car. Is there some sort of formula someone can give me, that will rotate the wheels based on how fast the car is moving?
