actionscript-3 - 在 AS3 中添加和删除子项？

Question

所以，我正在尝试做这样的事情，如果 Cosmo.hitTestObject，Asteroid 5 应该被删除，但是我希望它立即添加回不同的位置，所以命中测试不会自动触发。我该怎么做呢？

var nCount1:Number = 0;
timer_Text1.text = nCount1.toString();
addEventListener(Event.ENTER_FRAME,massCollect);

function massCollect(e:Event) {
    if (Cosmo.hitTestObject(Asteroid5)) {
        removeChild(Asteroid5);
        nCount1++;
        timer_Text1.text = nCount1.toString();
    }
    if (nCount1 == 5) {
        gotoAndStop(351, "Scene 1");
        removeEventListener(Event.ENTER_FRAME,massCollect);
    }
}

我会用这样的东西：

var nCount1:Number = 0;
timer_Text1.text = nCount1.toString();
addEventListener(Event.ENTER_FRAME, massCollect);

function massCollect(e:Event) {
    if (Cosmo.hitTestObject(Asteroid5)) {
        while (Cosmo.hitTestObject(Asteroid5) {
            Asteroid5.x = Math.floor(MAX_WIDTH * Math.random());
            Asteroid5.y = Math.floor(MAX_HEIGHT * Math.random());
        }
        removeChild(Asteroid5);
        nCount1++;
        timer_Text1.text = nCount1.toString();
    }
    if (nCount1 == 5) {
        gotoAndStop(351, "Scene 1");
        removeEventListener(Event.ENTER_FRAME, massCollect);
    }
}
