Roll Ball Toward Point

Unity Engine
1

easy to make the ball rolling in realistic way, I used this code:

var speed = 10.0;
var gravitypull = 0;

function FixedUpdate() {
 rigidbody.AddForce (Vector3(0, gravitypull, 0));
 
 var cameraTransform = Camera.main.transform;

   // Forward vector relative to the camera along the x-z plane   
   var forward = cameraTransform.TransformDirection(Vector3.forward);
   forward.y = 0;
   forward = forward.normalized;

   // Right vector relative to the camera
   // Always orthogonal to the forward vector
   var right = Vector3(forward.z, 0, -forward.x);
   rigidbody.AddForce(-forward * speed * Time.deltaTime);
   
  }

Then, I tried to let this ball roll rotation toward another game object, I used " transform.LookAt(target); " but it damage the realistic rolling which I made before, it let the ball crawl …!
my question:
how can let my ball roll in realistic way but toward a game object?

Rather than add the force in the forward direction of the ball, you can get the direction from the ball to the target and use that as the force vector:-

var heading: Vector3 = (target.position - transform.position).normalized;
rigidbody.AddForce(heading * pushForce);

Note that you don’t need to multiply the force by Time.deltaTime - this calculation is already done for you by the physics engine.

andeeee…
exactly, where i should add this to my code
