With AS3, MovieClip that has used “onEnterFrame” in AS2 is now:

mc.addEventListener(Event.ENTER_FRAME,doSomething);

function doSomething(event:Event):void {
	trace("Doing something");
}

And “onPress”, “onRelease”, “onRollOver” and “onRollOut” etc…, will be using mouse event like:

mc.addEventListener(MouseEvent.MOUSE_DOWN, function(event:MouseEvent) {
	event.target.parent.gotoAndStop("Somewhere");
});

Where we have “MouseEvent.MOUSE_UP”, “MouseEvent.MOUSE_DOWN”, “MouseEvent.MOUSE_OVER” and “MouseEvent.MOUSE_OUT”.
