hit.normal cube

hello, i have a character, which is controled by rigidbody. i want this to walk around a cube. the gravity works perfekt but the rotation of the character want to be equals to raycast's hit.normal, so that i can rotate the player around y axis. here the gravity script

 function FixedUpdate(){
     
     
     Colliders = Physics.OverlapSphere(transform.position, GravityZone.GetComponent("SphereCollider").radius*transform.localScale.y );
     for(var i = 0; i<=Colliders.length-1; i++){
         if(Colliders[i].gameObject.transform.rigidbody){
             var hit : RaycastHit;
             if(Physics.Raycast(Colliders[i].transform.position,(transform.position-Colliders[i].transform.position),hit)){
                 gravityUp = hit.normal;
                 Colliders[i].transform.rigidbody.AddForce(gravityUp*-9);
             }
             Debug.DrawRay(Colliders[i].transform.position,(transform.position-Colliders[i].transform.position),Color.red);
             //gravityUp = Colliders[i].transform.position - hit.normal;
             //gravityUp.Normalize();
             //Colliders[i].transform.rigidbody.AddForce(gravityUp*-9);
             if(Colliders[i].gameObject.tag=="Player"){
                 localUp = Colliders[i].gameObject.transform.up;
                 var q = Quaternion.FromToRotation(Vector3.up, hit.normal);
                 q = q * Colliders[i].gameObject.transform.rotation;
                 Colliders[i].gameObject.transform.rotation =                                         //schneller hinstellen bei nähere distance
                 Quaternion.Slerp(Colliders[i].gameObject.transform.rotation, q, 8*Time.deltaTime);///(Vector3.Distance(transform.position,Colliders[i].transform.position)-transform.localScale.y/2));
                 localForward = Colliders[i].gameObject.transform.forward;
             }
         }
     }
 }
