Making a MovieClip animation move

          import flash.display.MovieClip;

          import flash.events.Event;

          public class demo extends MovieClip

          {

                    private var obj:MovieClip;

                    public function demo()

                    {

                              obj = new MovieClip();

                              obj.addEventListener(Event.ENTER_FRAME, enterFrameHandler);

                    }

                    private function enterFrameHandler(e:Event):void

                    {

                              // if you want to move x, use this.

                              obj.x += 5;

                              // if you want to move y, use this.

                              obj.y += 5;

                    }

          }

}

If you want it to constantly be moving around, then look into using an Event.ENTER_FRAME listener with an event handler function that is incrementally changing the position properties (x and/or y) that represent the direction(s) in which you wish the movieclip to move.
