addFrameScript用法

如何判断一个mc播放完毕之后remove掉他呢，

目前我发现的两种做法，一种是：

    var boomMc:MovieClip = LoadResource.getMC("boom",LoadResource.resourceDm);
            boomMc.id = x+":"+y;
            gameManager.gameWord.uiLayer.addChild(boomMc);
            var nxy:Point = Node.getPostionByXY(x,y);
            var p:Point = this.localToGlobal(nxy);
            boomMc.x = p.x;
            boomMc.y = p.y;
            boomMc.addEventListener(Event.ENTER_FRAME,_enterFrame);
        }
        private function _enterFrame(evt:Event):void
        {
            var boom:MovieClip = evt.target as MovieClip;
            if(boom.currentFrame == boom.totalFrames)
            {
                boomsPlayFinishedNo ++;
                boom.parent && boom.parent.removeChild(boom);
                boom.removeEventListener(Event.ENTER_FRAME,_enterFrame);
            }
        }

另一种高大上的方法是：

    /**
         * NodeView 点击函数
         */        
        public function nodeClickHandler(node:Node):void
        {
            if(node.type == Node.TYPE_BOMBSHELL)
            {
                BattleEffectUtil.vibrationScreen(gameManager.gameWord);
                var boomAll:MovieClip = LoadResource.getMC("boomAll",LoadResource.resourceDm);
                function _remove():void
                {
                    boomAll.parent && boomAll.parent.removeChild(boomAll);
                }
                boomAll.addFrameScript(boomAll.totalFrames-1,_remove);
                gameManager.gameWord.uiLayer.addChild(boomAll);
                var nxy:Point = Node.getPostionByXY(node.x,node.y);
                var p:Point = gameManager.uiManager.gridView.localToGlobal(nxy);
                boomAll.x = p.x;
                boomAll.y = p.y;
            }
        }
