在编辑器（Unity，c#）中从另一个场景加载场景与先选择该场景不同
Scene loads differently when loaded from another scene than selecting that scene first, in the editor (Unity, c#)
确实是一个很简单的问题，但在网上搜索后我很难找到答案。
问题
场景没有完全加载，从另一个场景（通过 Application.LoadLevel() ），有些部分工作，有些部分不工作，而直接打开场景然后播放它工作正常。
我试过的
- 等待一段时间，看看它是否只是需要时间来加载（1 分钟以上），与它自己加载时的十秒相比。
- 构建它并查看问题是否重复出现，让我决定是否是由于编辑器造成的，例如当您切换场景并且灯光变暗时。然而，问题重演。
- 将我的 Unity 升级到版本 5.3.4f1，然后使用 SceneManager.LoadScene() 而不是 Application.LoadLevel()。一点变化都没有。
我认为可能是什么原因造成的
- 看了很多网页，我了解到 Unity 的场景加载和场景系统可能很烦人
感谢您阅读本文，我希望这是一个简单的问题，但对于一个缺乏经验的 Unity 用户 (ME) 来说，这是一个相当令人费解的问题。如果需要任何确切的细节，我会添加它们，但对我来说它们是不必要的（并且也需要付出很多努力）。
进一步的细节（如果你需要的话）

控制台消息
直接加载场景时
但有趣的是，当它从另一个场景加载时，它没有任何“2HEY”或“3HEY”的调试。
Time.frameCount 正在从游戏开始计算帧数。因此，如果您从另一个场景加载场景，Time.frameCount 肯定会大于 0。
此外，调试游戏比使用日志查看正在发生的事情更快。只需在 MonoDevelop 中点击 Play 并（对于 Unity 4.3 及以下版本）选择 Unity Debugger，在需要停止的地方放置断点并检查变量值，然后点击 Play 在 Unity 中。
祝你好运
