Question

我的play.lua中有一个计时器，当它达到0时会自动转到timeend.lua，这表示它的时间已经结束。但当我关闭timeend（通过按钮）的场景时，它会转到menu.lua，但效果不佳。当我触摸菜单中的播放按钮时，它只显示背景。

我不完全确定你的问题是什么，但我认为我有个好主意，我也是Corona的新手并遇到了类似的问题。

使用场景时，您需要清除destroyScene功能上的重要变量。基本上如果你不这样做并回到同一个场景你可能会遇到奇怪的问题。还有另外一件事你可以做。

进入下一个场景后，您可以removeScene内存中的前一个场景（将清除所有场景）。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，无论前一个场景是什么都允许这样做（因此它更具动态性）。

当我打电话给下一个场景时，我会做这样的事情：

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

然后在enterScene的下一个场景中，我检查了参数，如果它在那里，那么我删除了场景：

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

这可能与您所需要的一致。
