Help me.. i'm making rpg for my school project and the code hitTestObject inside NPC01 class is not working.

Here's my code:

Game.as

package {
    import flash.display.MovieClip;
    import flash.events.Event;

    public class Game extends MovieClip{
       var map:Map = new Map();
       var player:Player = new Player();
       var npc:NPC = new NPC();

       public function Game(){
         addChild(map);
         addChild(npc);
         addChild(player);
         this.addEventListener(Event.ENTER_FRAME,loop);
       }
       private function loop():void {
         npc.x = map.x;
         npc.y = map.y;
       }
     }
   }

NPC.as

    package  {
      import flash.display.MovieClip;
      import flash.events.Event;

      public class NPC extends MovieClip {

        var npc01:NPC01 = new NPC01();

        public function NPC() {
            // constructor code

            addChild(npc01);            

            npc01.x = 20;
            npc01.y = 0;
        }
    }
}

NPC01.as

package  {
    import flash.display.MovieClip;
    import flash.events.Event;

    public class NPC01 extends MovieClip {      

        var player:Player = new  Player();

        public function NPC01() {
            // constructor code
            this.addEventListener(Event.ENTER_FRAME, loop);
        }
        private function loop(e:Event):void
        {
            if(player.hitTestObject(npc)) {  //npc is a movieclip  inside NPC01
              trace("HIT!!");   
              }
        }

i got no error message. it just, whenever the player movieclip hits npc movieclip, the output doesn't show up..

i tried also to also to trackdown their position using:

trace( player.getBounds(stage) );
trace( npc.getBounds(stage) );

result:

(x=343, y=218, w=26, h=45)
(x=334, y=218, w=32, h=51)

it seems that they are colliding.

But when i write the hitTestObject code inside the Game.as under function loop, and the trace output show's up when the player hits npc.

i got no problem moving the charater 'player' around.

Sorry for my bad English.
