I’m using the following code to set a prototype for hitTest within a loaded mc. It works great the first time, but I need to test to see if it’s been called because it doesn’t work if the code gets called on successive loads…

```auto
 MovieClip.prototype.oldHitTest = MovieClip.prototype.hitTest;
        MovieClip.prototype.hitTest = function(x, y, sf) {
            var obj = {x:x, y:y};
            this._parent._parent.localToGlobal(obj);
            return this.oldHitTest(obj.x, obj.y, sf);
        };

```

Is there a way to test to see if the prototype has been called before? I was setting a variable in the \_parent movie initially, but I can’t do that now so I need to test to see if the prototype has been called…

Thanks!!!
