Professional :: Flip Card And Drag It Around

I'm trying to make a basic card game where I can flip the cards and also drag them around. Here's the code for card.as, the file that's controlling my cards.

package{ import flash.display.MovieClip;
import flash.events.MouseEvent;
public class Card extends MovieClip { private var _type:*;
public function Card() { this.buttonMode = true;
this.addEventListener(MouseEvent.CLICK, onClick);
} private function onClick(event:MouseEvent):void { this.play();
} public function setType(type:*):void { _type = type;
loader_mc.addChild(_type); }}}
 
I've been trying to add draggability to the card, but I'm not sure how to do it. Do I need a separate ".as" file to control it? Or, do I build it right into this file? If so, how would I do that? I tried making a separate ".as" file but then my basic card flipping code doesn't work.
