im making a basic game were you have to get past lodes of levels as a ball that has to dodge stuff and stay on the platforms i have a basic moving code but i want to make the ball roll like a ball when it moves. can someone help me please with some. this is my moving code so far

var speed = 3.0;
var rotateSpeed = 3.0;

function Update ()
{
   var controller : CharacterController = GetComponent(CharacterController);

   // Rotate around y - axis
   transform.Rotate(0, Input.GetAxis ("Horizontal") * rotateSpeed, 0);

   // Move forward / backward
   var forward = transform.TransformDirection(Vector3.forward);
   var curSpeed = speed * Input.GetAxis ("Vertical");
   controller.SimpleMove(forward * curSpeed);
}

transform.localRotation =(0, Input.GetAxis (“Horizontal”) * rotateSpeed, 0); does not work but thanks any way

It would be obvious with the physic engine, but if you want to do otherwise, keep in mind that, if you have a ball of radius 1, to rotate 360 degree, you have to move a distance of 2PI. And that’s when trigonometry magically make total sense !
