 function FixedUpdate(){

   // get current position:

   var myPos: Vector3 = rigidbody.position;

   // create ray from this object to the planet center:

   var ray: Ray = new Ray(myPos, target.position - myPos);

   var hit: RaycastHit;

   // do a Raycast that sees only the target collider:

   if (target.collider.Raycast(ray, hit, Mathf.Infinity)){

     // save distance to the surface in variable distance:

     distance = hit.distance;

   }

 }

 

 function OnGUI(){

   // show the distance with one decimal digit:

   

   GUI.Label(Rect(10,10,120,30), distance.ToString("F1"));

 }
