AsyncOperation 使用 AsyncOperation 确定操作是否已完成。
Destroys all GameObjects associated with the given scene and removes the scene from the SceneManager.
The given scene name can either be the full scene path, the path shown in the Build Settings window or just the scene name. If only the scene name is given this will load the first scene in the list that matches. If you have multiple scenes with same name but different paths, you should use the full scene path.
Examples of supported formats:
"Assets/Scenes/Scene1.unity"
"Scenes/Scene1"
"Scene1"
Note that this is case insensitive and due to it being async there are no guarantees about completion time.
Note that assets are currently not unloaded, in order to free up asset memory call Resources.UnloadAllUnusedAssets.
