SceneManager.LoadScene & SceneManager.SetActiveScene
阿新 • • 發佈：2018-10-31
問題：SceneManager.LoadScene之後呼叫SceneManager.SetActiveScene報錯，提示場景未載入。(ArgumentException: SceneManager.SetActiveScene failed; scene 'XXX' is not loaded and therefore cannot be set active)
原因：SceneManager.LoadScene
Unity5.x
這個函式呼叫後馬上載入場景
Unity2017.x
這個函式呼叫後第二幀結束的時候完成載入
2017/2018的文件說明：“When using SceneManager.LoadScene, the loading does not happen immediately, it completes in the next frame. This semi-asynchronous behavior can cause frame stuttering and can be confusing because load does not complete immediately.”
解決辦法：
在SceneManager.LoadScene呼叫之後新增2個 yield return new WaitForEndOfFrame(); 就OK了。
PS：Unity5.x無此問題
