使用Corona SDK使用情节提要重新启动游戏，并出现奇怪错误

我目前正在制作一个在科罗纳的游戏，有三个不同的场景，一个菜单，一个游戏，和一个游戏结束场景。在游戏中，当你们触摸你们的精灵时，它会沿着屏幕上下移动，在第一次玩的时候，它会很好地工作。但是，当你撞到某个东西并转到重新启动屏幕时，它会再次加载游戏，当你触摸屏幕时，精灵几乎不会向上移动，如果你放开它，它会迅速下降到底部，你无法通过再次触摸屏幕将其推上。你知道为什么会出现这个问题吗

-- "createScene" event is dispatched if scene's view does not exist

-- "enterScene" event is dispatched whenever scene transition has finished
scene:addEventListener( "enterScene", scene )

-- "exitScene" event is dispatched before next scene's transition begins
scene:addEventListener( "exitScene", scene )

-- "destroyScene" event is dispatched before view is unloaded, which can be
-- automatically unloaded in low memory situations, or explicitly via a call to
-- storyboard.purgeScene() or storyboard.removeScene().
scene:addEventListener( "destroyScene", scene )

在我看来，问题在于您在退出到下一个场景之前没有删除所有侦听器。确保清除所有变量并正确结束所有事件侦听器。我个人对故事板不太熟悉。如果您不能让它工作，我建议您不要使用任何东西，只使用一个main.lua，只需要从main中调用其他lua文档的函数即可。您自己处理错误清理可能会容易得多。

有了这样的功能，您确实需要发布一些代码/示例。否则将很难帮助您。@MagicMan我刚刚添加了一些代码示例。谢谢你的帮助。
