Actionscript 3 mouse_over play movie - actionscript-3

Question

I'm trying to play a movie clip when I mouse_over it. I can do it fine by doing:
mc1.addEventListener(MouseEvent.MOUSE_OVER,mover);
function mover(e:MouseEvent):void {
mc1.play();
}
But, I want to use the same function for other movie clips, for example, to play movieclip2, movieclip3 etc.
How would I achieve this?

Answer 1

mc1.addEventListener(MouseEvent.MOUSE_OVER,mover);
mc2.addEventListener(MouseEvent.MOUSE_OVER,mover);
mc3.addEventListener(MouseEvent.MOUSE_OVER,mover);
function mover(e:MouseEvent):void {
e.currentTarget.play();
}

Answer 2

You can make a class to encapsulate your logic for example, to access the MovieClip from the calling function, use the property of the Event object
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class PlayMovieClip {
// register the mouse over event with whatever MovieClip you want
public static function register(mc:MovieClip):void{
mc.addEventListener(MouseEvent.MOUSE_OVER,mover);
}
// unregister the event when you dont need it anymore
public static function unregister(mc:MovieClip):void{
mc.removeEventListener(MouseEvent.MOUSE_OVER, mover);
}
// the MouseEvent will be throw whenever the mouse pass over the registered MovieClip
// and in the MouseEvent property you have the targeted object
// so use it
public static function mover(e:MouseEvent):void{
// check if we have really a MovieClip
var mc:MovieClip=e.currentTarget as MovieClip;
if (mc!==null) {
// we have a MovieClip so we can run the function play on it
mc.play();
}
}
}
usage:
PlayMovieClip.register(mc1);
...
PlayMovieClip.register(mcX);
and to remove the event:
PlayMovieClip.unregister(mc1);
...
PlayMovieClip.unregister(mcX);
