更新： 嗨@DevfaR 哈，我已经用corona模板从零开始重新启动，并解决了一些问题： 1） 如果使用本地组对显示对象进行分组，exitScene/destroyScene实际上会执行一些操作。它将删除显示组！ 不是很明显，因为其中只有一个声明，没有这样的代码 2） 我之所以要把所有的东西都拿走，是因为什么都没用。所以我几乎尝试了网络下的一切 3） 它不起作用的原因是因为我把我的显示对象创建成了一个函数。不知怎的，显示组没有传递到那里。如果我将代码移动到createScene函数中，那么在进入下一个场景时，它确实会被清除 问题是。。我真的很想分组我的木偶创作代码！ e、 g 我通过了（组），因为createPuppet函数不允许我指定 本地组=self.view 我的电子邮件地址是edualczatebed@gmail.com
感谢您的帮助您的代码中有很多错误，您实现它的方式不太好，因为当您转到一个场景，然后切换到另一个场景时，您删除了

entersecenedestroyScene希望这能帮助你解决你的问题你能提供更多的代码吗？仅仅给出一个ITI@DevfaR的片段就很难指出你的问题发生在哪里。这是正确的，我真的不明白如何使用故事板，因为那里没有教程。论坛只提供少量代码和解决方法。因此，非常感谢您的帮助，相信我。现在，您所说的非常有趣：“注意，当我转到场景2时，我没有费心删除destroyScene上的对象和侦听器，这是因为每当我更改场景时，将对象插入显示组时，它总是会删除对象”是这样吗？为什么没有销毁场景？就在开始工作之前，试图通过将代码直接放入我的level5.lus来让代码正常工作，下面是我的问题。。我的level5.lua是从菜单中调用的。lua我是否需要在每个“levelx.lua”的开头有local storyboard=require（“storyboard”）local scene=storyboard.newScene（）？（因为就像这样它不起作用）=我得到了一个scene5.lua:16尝试索引全局“scene”（一个nil值）我在exitScene下面的代码中添加了destroyScene。关于您的问题如果您需要在每个级别上使用故事板是的，您需要使用故事板切换不同的布局这就是为什么如果您使用故事板创建新项目，会生成场景模板。我很想解释story board中的所有功能试着了解它是如何工作的如果你有问题，请转到这个链接，在这里问一下信不信由你我浏览了这个文档大约10次。它没有解释为什么我们需要在每个函数中添加“localgroup=self.view”？（我们知道吗？）它的作用和方式？调用exit_场景时，是否会删除场景中的所有对象？函数场景也一样：CreateSecene（事件）我应该调用场景吗：。。或者场景一：场景二：。。对于每一个级别（scene1.lua，scene2.lua），都有很多没有解释的东西，我希望你能解释。有人会的。无论如何谢谢你
