ETeeskiTutorials FPS1.8 Basic Gun With Weight - Help needed

Hey, I've been following ETeeski's tutorials but trying to adapt them to my own game as and when I need them. At the moment I'm trying to add a torch to my game (my first item), trying to give it some weight and make it follow the camera, but although it rotates with the camera it doesn't move with it, though I suspect this is because I don't have the same MouseLookScript. This is the code I'm using:

Code (csharp):

1. var cameraObject : GameObject;
2.  
3. @HideInInspector
4. var targetXRotation : float;
5. @HideInInspector
6. var targetYRotation : float;
7. @HideInInspector
8. var targetXRotationV : float;
9. @HideInInspector
10. var targetYRotationV : float;
11.  
12. @HideInInspector
13. var yRotation : float; //I put this in here because its usually in the MouseLookScript, which i dont have
14. @HideInInspector
15. var xRotation : float; //I put this in here because its usually in the MouseLookScript, which i dont have
16.  
17.  
18.  
19. var rotationSpeed :float;
20.  
21. var holdHeight : float;
22.  
23. var holdSide : float;
24.  
25. function Update(){
26.  
27. yRotation += Input.GetAxis("Mouse X"); //Here is what is in the MouseLookScript to change the Y rotation, slightly edited
28.  
29. xRotation -= Input.GetAxis("Mouse Y"); //Here is what is in the MouseLookScript to change the X rotation, slightly edited
30.  
31.  
32. transform.position = cameraObject.transform.position + (Quaternion.Euler(0,targetYRotation,0) * Vector3(holdSide,holdHeight,0));
33.  
34. targetXRotation = Mathf.SmoothDamp(targetXRotation,xRotation,targetXRotationV, rotationSpeed);
35. targetXRotation = Mathf.SmoothDamp(targetYRotation,yRotation,targetYRotationV, rotationSpeed);
36.  
37. transform.rotation = Quaternion.Euler(targetXRotation,targetYRotation,0);
38. }

Thanks.
