var open : boolean = false;

 var openAnimationString : String;
 var closeAnimationString : String;
 
 var buttonTransform : Transform;
 var distToOpen : float = 4;
 
 @HideInInspector
 var playerTransform : Transform;
 @HideInInspector
 var cameraTransform : Transform;
 
 var openSound : AudioClip;
 var closeSound : AudioClip;
 
 function Awake ()
 {
     playerTransform = GameObject.FindWithTag("Player").transform;
     cameraTransform = GameObject.FindWithTag("MainCamera").transform;
     if (open)
         GetComponent.<Animation>().Play(openAnimationString);
 }
 
 function Update () 
 {
     var alreadyChecked : boolean = false;
     var angle : float = Vector3.Angle(buttonTransform.position - cameraTransform.position, buttonTransform.position + 
     (cameraTransform.right * buttonTransform.localScale.magnitude) - cameraTransform.position);
     if (Vector3.Distance(playerTransform.position,buttonTransform.position) <= distToOpen)
     if (Vector3.Angle(buttonTransform.position - cameraTransform.position, cameraTransform.forward) <= angle)
     if (Input.GetButtonDown("Use Key") && !GetComponent.<Animation>().isPlaying)
     {
         if (open)
         {
             GetComponent.<Animation>().Play(closeAnimationString);
             open = false;
             alreadyChecked = true;
             if (closeSound)
                 GetComponent.<AudioSource>().PlayOneShot(closeSound);
         }
         if (!open && !alreadyChecked)
         {
             GetComponent.<Animation>().Play(openAnimationString);
             open = true;
             if (openSound)
                 GetComponent.<AudioSource>().PlayOneShot(openSound);
         }
     }
 }
