为什么进入下一个场景以后第一个场景手动的元件拖动仍然显示？

Question

stop();var dep:Number = 0;hitMc_arr = ["xlzHit", "hqzHit", "xxzHit", "xhzHit", "dmzHit"];//要碰撞的mc实例名xlz_arr = [];//笑脸组的分数hqz_arr = [];//红旗组的分数xxz_arr = [];//略xhz_arr = [];//dmz_arr = [];////函数调用复制正(xlz,xlz_arr,xlz_txt);复制正(hqz,hqz_arr,hqz_txt);复制正(xxz,xxz_arr,xxz_txt);复制正(xhz,xhz_arr,xhz_txt);复制正(dmz,dmz_arr,dmz_txt);复制负(kf_mc);//函数定义function 复制正(mc, _arr, t){ mc.n = 0; mc.onRollOver = function() { this.n++; dep++; trace(dep); var newMc:MovieClip = this.duplicateMovieClip(this._name + this.n, dep); trace(newMc); 拖动(newMc,_arr,t); };}function 拖动(mc:MovieClip, _arr:Array, t:TextField){ mc.onPress = function() { this.startDrag(); }; mc.onRelease = mc.onReleaseOutside = function () { this.stopDrag(); //向分数数组中增加1 t.text = 计分(_arr, 10); };}

function 碰撞(mc)
{
if (mc.k == undefined)
{
mc.k = 0;
}
mc.k++;
for (var _i in hitMc_arr)
{
if (mc.hitTest(_root[hitMc_arr[_i]]))
{
//trace(_root[hitMc_arr[_i]] + "撞了");
lb = _root[hitMc_arr[_i]]._name.substring(0, 3);
if (mc.k == 1)
{
//向分数数组中增加-1
llb = _root[lb + "_arr"];
lbt = _root[lb + "_txt"];

}
}
}
}

Answer 1

但凡用duplicateMovieClip /attachMovieClip/swapDepths 设置过MC层级的，时间轴跳帧时，MC是不受影响的，需要手动用代码作清除处理。

Answer 2

这是一个封装逻辑，假设将场景看成一个对象容器，则你拖动复制出来的子对象一定要被装入这个容器才是正常的逻辑。否则当场景更换，未在场景容器内的物件还会留在舞台上。

Answer 3

乱的来，初步估计，函数执行范围包括了下一个“场景”。或者说在第二个场景有第一个场景的组件
