按场景名称加载随机场景在编辑器中工作，但不在独立应用程序

Question

我正在编写一个管理器脚本，该脚本在List中存储来自Object名称数组的字符串集合。这些对象实际上是我在团结编辑器中拖入公共数组的游戏场景。从那里我在GetRandomScene（）中选择其中一个字符串，然后通过LoadScene（）将字符串名称传递给SceneManager.LoadScene(sceneName, LoadSceneMode.Single);。

此脚本附加到空白场景（构建设置中的第一个场景），目的是加载我拖动到Object [] forestScenes数组中的一个场景。这在编辑器中工作正常，但是当我构建为独立应用程序时它不起作用。为了正常运行，我需要修改什么？
