AS2 Detecting When Mouse Leaves the Stage

Posted by Alan in Actionscript, Code, Flash Jun 7th, 2010 | one response

A handy script when working with Actionscript 2 code. Because there is no Actionscript 3 Event.MOUSE_LEAVE equivalent in AS2. the best thing to do is to write a custom script for mouse detection on stage. I don’t know who authored this, but I’d like to record it so it doesn’t get lost on the internet.

     var mouse_dx:Number=_xmouse;
     var mouse_dy:Number=_ymouse;
     var mouseSpeed:Number=1;
 
 
     function checkPosition(Void):Void 
      {
	   if(_xmouse<mouseSpeed || _xmouse>(Stage.width-mouseSpeed) || _ymouse<mouseSpeed  || _ymouse>(Stage.height-mouseSpeed)) 
            {
		in_mc._visible=false;
		out_mc._visible=true;
		trace("out");
	    } 
            else 
            {
		in_mc._visible=true;
		out_mc._visible=false;
		trace("in");
	    }
       }
 
      checkPosition(Void);
 
      var mouseListener:Object = new Object();																					
      mouseListener.onMouseMove = function():Void 
      {																				
	    mouse_dx = Math.abs(mouse_dx-_xmouse);
	    mouse_dy = Math.abs(mouse_dy-_ymouse);
	    mouseSpeed = mouse_dx > mouse_dy ? mouse_dx  : mouse_dy;
	    mouseSpeed +=1;
	    checkPosition(Void);
 	    mouse_dx=_xmouse;
            mouse_dy=_ymouse;
     }
 
     Mouse.addListener(mouseListener);
