类型错误：错误＃1009无法找到空对象

问题描述：

我得到这个真的很烦错误 “类型错误：错误＃1009：在monke2_fla无法访问空对象引用的属性或方法 :: MainTimeline/UPDATE2（）” 我找不到NULL var，除了＃1009错误之外，任何帮助都会很棒，因为脚本工作正常。类型错误：错误＃1009无法找到空对象

这是一个任务就是在到期我打砖墙，在此先感谢

这还不够远。不幸的是，这是时间轴编码的缺陷。这可能是因为您的任何数量的影片剪辑/显示对象或儿童未正确设置。确保你的实例名称是正确的。检查你的父/子层次结构，确保像“Bunch.parent”这样的东西实际上有一个父对象。添加跟踪语句以确定在抛出错误之前运行的最后一件事情。 –

好，靠近你的代码的底部，你说：Bunch.parent.removeChild(Bunch);

但是你也有：Banana_mc1.addEventListener(Event.ENTER_FRAME, moveDown);它调用一个函数，保持引用Bun ch。

您可以通过不删除束来测试。如果修复了null var问题，那么你将不得不决定如何继续。你想让游戏继续或结束后束消失？

再就是也是这个：

hitAry[i].parent.removeChild(hitAry[i]); 
    trace(hitAry[i]);

你试图跟踪它，你删除它之后！那 mightmake hitAry [i] null！

这不会使'hitAry [i]'无效，但是如果'hitAry'中的某个元素没有添加到stage（或刚刚从其父元素中移除），则其“parent”属性为null。这很可能是OP的错误，尽管碰到'Bunch'可能会产生相同的结果。 – Vesper
