      根据index得到一个场景
      GetSceneAt   Get the Scene at index in the SceneManager's list of loaded Scenes.
     
      通过BuildIndex得到一个场景
      GetSceneByBuildIndex   Get a Scene struct from a build index.
     
      通过名字得到一个场景
      GetSceneByName   Searches through the Scenes loaded for a Scene with the given name.

      把某个游戏物体移动到场景当中

      激活某个场景
      SetActiveScene   Set the Scene to be active.
     
      异步卸载某个场景
      UnloadSceneAsync   Destroys all GameObjects associated with the given Scene and removes the Scene from the SceneManager

    CreateScene Create an empty new Scene at runtime with the given name.
    GetActiveScene Gets the currently active Scene.
    GetSceneAt Get the Scene at index in the SceneManager's list of loaded Scenes.
    GetSceneByBuildIndex Get a Scene struct from a build index.
    GetSceneByName Searches through the Scenes loaded for a Scene with the given name.
    GetSceneByPath Searches all Scenes loaded for a Scene that has the given asset path.
    LoadScene Loads the Scene by its name or index in Build Settings.
    LoadSceneAsync Loads the Scene asynchronously in the background.
    MergeScenes This will merge the source Scene into the destinationScene.
    MoveGameObjectToScene Move a GameObject from its current Scene to a new Scene.
    SetActiveScene Set the Scene to be active.
    UnloadSceneAsync Destroys all GameObjects associated with the given Scene and removes the Scene from the SceneManager.

    场景构建

      File->Build Settings

      将场景放到Scenes In Build中,默认第一个场景index下标是0

      按下空格,加载下标为0的场景(Gary.scene)

      通过OnSceneLoader()方法,触发加载场景触发的事件

    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using UnityEngine.SceneManagement;
    
    public class Scene_Gary : MonoBehaviour {
    
        // Use this for initialization
        void Start () {
            //将OnSceneLoader()方法添加到场景管理类
            SceneManager.sceneLoaded += this.OnSceneLoader;
        }
    
        //当场景加载出来调用触发的事件
        void OnSceneLoader(Scene scene,LoadSceneMode mode)
        {
            Debug.Log("Hello Gary~");
        }
            
        // Update is called once per frame
        void Update () {
            if (Input.GetKeyDown(KeyCode.Space))
            {
                SceneManager.LoadScene(0);
            }
        }
    }
