我有一个计时器play.lua，当它达到 0 时，它会自动转到timeend.lua这表明它的时间到了。但是当我关闭（通过按钮）的场景时，timeend它会进入menu.lua但不能正常工作。当我触摸菜单中的播放按钮时，它只显示背景。

我不完全确定您的问题是什么，但我认为我有一个好主意，我也是 Corona 的新手并且遇到了类似的问题。

处理场景时，您需要清除destroyScene函数上的重要变量。基本上，如果您不这样做并回到同一个场景，您可能会遇到奇怪的问题。您还可以做另一件事。

一旦你进入你的下一个场景，你可以removeScene从记忆中的前一个场景（这将清除所有它）。您可以在下一个场景的 enterScene 函数中执行此操作。我实现了一个解决方案，无论之前的场景是什么（所以它更加动态）。

当我调用下一个场景时，我会这样做：

local options = {effect = "fade",800,params={destroy = true,toDestroy = 'scenes.gameOver'}}
storyboard.gotoScene('scenes.mainMenu',options)

然后在我的下一个场景中，enterScene我检查参数，如果它在那里，那么我删除场景：

local params = event.params
--Check for any previous scenes to destroy
if params and params.destroy == true then
    storyboard.removeScene(params.toDestroy)
end

这可能符合您的需要。
