来自另一个屏幕后，我的场景没有重新加载所有变量

Question

我有2个屏幕，一个是level1场景＆amp;另一个是level2场景，玩家在level1场景中死亡后，所有变量都被销毁了。已加载level2场景，我在level2中有一个触摸侦听器，会重新加载level1，但问题是level1中的所有变量都没有重新初始化＆amp;相反总是调用scene:hide方法，我无法弄清楚我的代码有什么问题，下面是我的代码

level1 code

Answer 1

您可以尝试在scene：show（）

中将此调用添加到level2

local prevScene = composer.getSceneName( "previous" ) if (prevScene ~= nil) then composer.removeScene(prevScene) end

此外，您应该尝试在创建后将所有对象添加到sceneGroup。看一下场景：本网站的create（）部分

https://coronalabs.com/blog/2014/01/21/introducing-the-composer-api-plus-tutorial/

初始化对象后，应使用sceneGroup：insert（object）将它们添加到场景中。
