AS3.0 点击按钮后 再点击复制出的MC 可将其删除

小弟新手，在FLASH制作中碰到这个问题，先附上代码
import flash.events.MouseEvent;
btn.addEventListener(MouseEvent.CLICK,onClick);
function onClick(evt:MouseEvent):void
{
var mc:Mc=new Mc();
mc.x =500;
mc.y = 350;
mc.addEventListener(MouseEvent.CLICK, clickHandler);
mc.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownListener);
mc.addEventListener(MouseEvent.MOUSE_UP, mouseUpListener);
addChild(mc);

function clickHandler(event:MouseEvent):void {
trace("You clicked the ball");
}
function mouseDownListener(event:MouseEvent):void {
mc.startDrag();
}
function mouseUpListener(event:MouseEvent):void {
mc.stopDrag();
}
}
bat.addEventListener(MouseEvent.CLICK,onClickx);
function onClickx(evt:MouseEvent):void
{
var mcx:Mx=new Mx();
mcx.x =500;
mcx.y = 350;
mcx.addEventListener(MouseEvent.CLICK, clickHandler);
mcx.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownListener);
mcx.addEventListener(MouseEvent.MOUSE_UP, mouseUpListener);
addChild(mcx);

function clickHandler(event:MouseEvent):void {
trace("You clicked the ball");
}
function mouseDownListener(event:MouseEvent):void {
mcx.startDrag();
}
function mouseUpListener(event:MouseEvent):void {
mcx.stopDrag();
}
}

点击两按钮分别出现两个元件，我还想制作个按钮点击之后再点元件可令其消除，请求各位大哥该如何制作！谢谢

你的脚本有问题。

可以用帧频事件 var num=1000//mc的总帧数 mc.gotoandstop(num) stage.addeventlistener(event:enter_farme,run) function run(e:event)｛ num-- mc.gotoandstop(num) ｝ //函数里可以加条件如num为0时删除事件 没测试也不知对不,方法是这样
