我开始制作舞台宽度：800，高度 600。

然后我在舞台上添加了一个空白的 MovieClip 并旋转它以获得 3d 外观。然后，我将地图图形和播放器图形添加到黑色 MovieClip。然后我将对象放置到地图图形中。基本上，当按下向上键时，它会移动地图图形，当按下左/右键时，它会旋转空白影片剪辑。

现在的问题是，当我尝试获取地图图形上的对象与玩家图形之间的距离，并尝试根据距离对它们进行重新排序时。出于某种原因，当我使用 (trace(Ground.getChildAt(0)); 时，我得到 [object Shape] 而不是 [object Crate]。

我不确定这是否是整个问题，或者我可能没有正确分类它们。对此的任何帮助将不胜感激。

这是代码：

addChild(World);

您错误地实现了冒泡排序。Sort2应该从头到尾运行Sort1+1，而不是从 1 开始。此外，如果您的evergreen班级有嵌套的 MC 或嵌套的 Shape，它也可能最终被排序。
