　　Unity場景切換SceneManager　　官方文檔：傳送門

 

 

靜態方法

　　創建場景

　　CreateScene　　 Create an empty new Scene at runtime with the given name.

 

　　得到當前激活的場景
　　GetActiveScene　　 Gets the currently active Scene.

 

　　根據index得到一個場景
　　GetSceneAt　　 Get the Scene at index in the SceneManager's list of loaded Scenes.

 

　　通過BuildIndex得到一個場景

　　GetSceneByBuildIndex 　　Get a Scene struct from a build index.

 

　　通過名字得到一個場景
　　GetSceneByName 　　Searches through the Scenes loaded for a Scene with the given name.

　　

　　通過路徑得到一個場景
　　GetSceneByPath　　 Searches all Scenes loaded for a Scene that has the given asset path.

 

　　加載場景
　　LoadScene 　　Loads the Scene by its name or index in Build Settings.

 

　　異步加載場景
　　LoadSceneAsync 　　Loads the Scene asynchronously in the background.

 

　　合並兩個場景
　　MergeScenes　　This will merge the source Scene into the destinationScene.

 

　　把某個游戲物體移動到場景當中
　　MoveGameObjectToScene 　　Move a GameObject from its current Scene to a new Scene.

 

　　激活某個場景
　　SetActiveScene 　　Set the Scene to be active.

 

　　異步卸載某個場景
　　UnloadSceneAsync 　　Destroys all GameObjects associated with the given Scene and removes the Scene from the SceneManager

場景構建

　　File->Build Settings

　　將場景放到Scenes In Build中,默認第一個場景index下標是0

 

　　按下空格，加載下標為0的場景(Gary.scene)

　　通過OnSceneLoader()方法，觸發加載場景觸發的事件
