Which movie clip did I click?

1

I know this is probably a dumb question.

How can I tell what movie clip I clicked?


MovieClip.prototype.onEnterFrame = function() {
     this.onMouseDown = function() {
          //open doors
          openDoors();
     };
};

is it hitTest?

Thanks,
RMB

MovieClip.prototype.onPress = function() {
	openDoors();
	trace(this);//will output the movieclip you just clicked
};
