Good luck!

I tried to add a camera bumper, but it's still not working. Here's the code: var target : Transform; var distance = 10.0;

 var xSpeed = 150.0;
 var ySpeed = 100.0;
  
 var yMinLimit = 5;
 var yMaxLimit = 80;
  
 var distanceMin = 3;
 var distanceMax = 15;
  
 private var x = 0.0;
 private var y = 0.0;
 
 
 ////////////////////////test
 var distance_bumper : float = 3.0;
 var height : float = 1.0;
 var damping : float = 5.0;
 var smoothRotation : boolean = true;
 var rotationDamping : float = 10.0;
  
 var targetLookAtOffset : Vector3;         // allows offsetting of camera lookAt, very useful for low bumper heights
  
 var bumperDistanceCheck : float = 2.5;    // length of bumper ray
 var bumperCameraHeight : float = 1.0;     // adjust camera height while bumping
 var bumperRayOffset : Vector3;         // allows offset of the bumper ray from target origin
 
 
 ////////////////////////////////
 function FixedUpdate() {
  
     var wantedPosition = target.TransformPoint(0, height, -distance_bumper);
  
     // check to see if there is anything behind the target
     var hit : RaycastHit;
     var back = target.transform.TransformDirection(-1 * Vector3.forward);    
  
     // cast the bumper ray out from rear and check to see if there is anything behind
     if (Physics.Raycast(target.TransformPoint(bumperRayOffset), back, hit, bumperDistanceCheck) 
               && hit.transform != target) { // ignore ray-casts that hit the user. DR
         // clamp wanted position to hit position
         wantedPosition.x = hit.point.x;
         wantedPosition.z = hit.point.z;
         wantedPosition.y = Mathf.Lerp(hit.point.y + bumperCameraHeight, wantedPosition.y, Time.deltaTime * damping);
     } 
      
 }
