Turning camera by -120 degrees on grounded right mouse button

Hi everyone,

script works fine only by specific rotation of player. I think I did bad think about euler rotation.
It should works like if you are running, you can turn back if monster is hunting you. I hope you understand.

Code (csharp):

1.  
2. var TurningCam : Transform;
3. var rotationSpeed = 5.0;
4. var rightClicked : boolean = false;
5. var endturn : boolean = false;
6.  
7. @script AddComponentMenu("Camera-Control/Mouse Orbit")
8.  
9. private var myVector : Vector3;
10. private var angle : float;
11.  
12. function Update (){
13.     if (Input.GetMouseButtonDown(1)){
14.         rightClicked = true;
15.         enableControl(false);
16.          }
17.    
18.     if (Input.GetMouseButtonUp(1)){
19.         rightClicked = false;
20.         enableControl(true);
21.          }
22. }
23.  
24. function enableControl(enabled : boolean){
25.       GameObject.Find("Main Camera").GetComponent(MouseLook).enabled = enabled;
26.       GameObject.Find("Player").GetComponent(MouseLook).enabled = enabled;
27. }
28.  
29. function FixedUpdate () {
30.     if (rightClicked) {
31.             myVector.x = TurningCam.transform.eulerAngles.x;
32.             myVector.z = TurningCam.transform.eulerAngles.z;
33.                    
34.             TurningCam.transform.eulerAngles = myVector;
35.            
36.             if(myVector.y >= -120.0){
37.                    
38.                 angle -= 300 * Time.fixedDeltaTime;
39.                 myVector.y = angle;                    
40.             }
41.     }else{         
42.             myVector.x = TurningCam.transform.eulerAngles.x;
43.             myVector.z = TurningCam.transform.eulerAngles.z;
44.                    
45.             TurningCam.transform.eulerAngles = myVector;
46.                      
47.             if(myVector.y <= 0){
48.                    
49.                 angle += 300 * Time.fixedDeltaTime;
50.                 myVector.y = angle;                    
51.             }              
52.          }
53.  }  
54.
