Rotation of the mouse activates a boxcollider2d in javascript.

Hello everyone!

I am trying to change this script that turns the mouse cursor to 360 degrees. I added a boxcollider2d so that activates when the mouse wheel position 180 °. Unfortunately this does not happen, the boxcollider remains active when I start the game.

Any solution?

script:

 #pragma strict
 
 var yourCursor : Texture2D;  // Your cursor texture
  var cursorSizeX : int = 16;  // Your cursor size x
  var cursorSizeY : int = 16;  // Your cursor size y
  
  var speed = 90.0;
  private var angle = 0.0;
  
  var box : GameObject;
      
      function Start()
      {
          Screen.showCursor = false;
                   
          box.GetComponent(BoxCollider2D).enabled = false;
      
      }
      
      function Update()
      {
       { 
        if (Input.GetMouseButton (0))
          
      angle -= Time.deltaTime * speed;
      angle = angle % 360.0;
      box.GetComponent(BoxCollider2D).enabled = true;
      Screen.showCursor = false;
    
      }
       
       
       {
        if (Input.GetMouseButton (1))
          
      angle += Time.deltaTime * speed;
      angle = angle % 360.0;
      box.GetComponent(BoxCollider2D).enabled = true;
      Screen.showCursor = false;
   
      }
      }    
           
      function OnGUI()
      {
      
      var matx = GUI.matrix;
      var x = Event.current.mousePosition.x-cursorSizeX/2.0;
      var y = Event.current.mousePosition.y-cursorSizeY/2.0;
      var pivot = Vector2(x + cursorSizeX / 2.0,y + cursorSizeY / 2.0);
      GUIUtility.RotateAroundPivot(angle, pivot);
      GUI.DrawTexture (Rect(x, y, cursorSizeX, cursorSizeY), yourCursor);
      GUI.matrix = matx;
      
     
       }

Script Solution:

  function Update()
      {
       { 
        if (Input.GetMouseButton (0))
          
      angle -= Time.deltaTime * speed;
      angle = angle % 180.0;
      box.GetComponent(BoxCollider2D).enabled = true;
      Screen.showCursor = false;
    
      }
       
       
       {
        if (Input.GetMouseButton (1))
          
      angle += Time.deltaTime * speed;
      angle = angle % 180.0;
      box.GetComponent(BoxCollider2D).enabled = true;
      Screen.showCursor = false;
   
      }
      }
