AsyncOperation Use the AsyncOperation to determine if the operation has completed.
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 unload 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:
"Scene1"
"Scene2"
"Scenes/Scene3"
"Scenes/Others/Scene3"
"Assets/scenes/others/scene3.unity"
Note: This is case-insensitive and due to it being async there are no guarantees about completion time.
Note: Assets are currently not unloaded. In order to free up asset memory call Resources.UnloadUnusedAssets.
Note: It is not possible to UnloadSceneAsync if there are no scenes to load. For example, a project that has a single scene cannot use this static member.
