Hello, I have a problem. When rotating my character he rotates on one foot. I want the rotation to be directly in the middle of him, My entire code is here:

 #pragma strict
 
 public var Dest : boolean = false;
 
 var speed : float;
 var rotateSpeed : float = 3.0;
 var MisslePREF : Transform;
 var jumpSpeed : float = 3.0;
 var Health : int = 100;
 var Mainplayer : Transform;
 var CSpawn : Transform;
 var DPlayer : Transform;
 var isGrounded : boolean;
 function Start () {
 Screen.lockCursor = false;
 Health = 100;
 Physics.gravity = Vector3(0, -115.0, 0);
 }
 
 function Update (){
 
 
 Screen.lockCursor = true;
 
 if(Health <= 0){
 Respawn();
 }
 
 Screen.lockCursor = true;
 if(!animation.isPlaying){
 animation.CrossFade ("fps_idle");
 animation["fps_idle"].speed = 0.5;
 }
     if(Input.GetButton("forward")){
     transform.position += transform.right;
     animation["fps_run"].speed = 1;
     animation.CrossFade("fps_run");
     }
         if(Input.GetButton("backward")){
     transform.position -= transform.right;
     animation.CrossFade("fps_back");
     }
         if(Input.GetButton("left")){
     transform.position += transform.forward;
     animation.CrossFade("fps_strafe_left");
     }
         if(Input.GetButton("right")){
     transform.position -= transform.forward;
     animation.CrossFade("fps_strafe_right");
     }
 
     if(Input.GetButtonDown("Jump")){
         animation["fps_jump"].speed = 0.5;
     transform.position += transform.up * jumpSpeed * Time.deltaTime * 15;
     animation.Play("fps_jump");
     }
     transform.Rotate(0, Input.GetAxis ("Mouse X") * rotateSpeed, 0);
     
     }
     
     
     
     //rotate around y - axis
     
     
     function OnCollisionEnter(col : Collision){
     if(col.gameObject.tag == "missleP2"){
     Health -=10;
     }
     if(col.gameObject.name == "LavaPlatform"){
         Debug.Log("You Are Now Dead");
     Health -=100;
     }
     if(col.gameObject.name == "fallout"){
     Debug.Log("You Are Now Dead");
     Health -=100;
     }
     }
     function OnGUI(){
     GUI.Label(Rect(1890,15,200,100), Health.ToString());
     }
     function Respawn(){
     Health = 100;
     transform.position = GameObject.Find("spawn1").transform.position;
     
 }

Thanks in advance!
