private GameObject[] getDontDestroyOnLoadGameObjects()
    var allGameObjects=new List<GameObject>();
    allGameObjects.AddRange(FindObjectsOfType<GameObject>());
    //移除所有场景包含的对象
    for(var i=0;i<SceneManager.sceneCount;i++)
        var scene=SceneManager.GetSceneAt(i);
        var objs=scene.GetRootGameObjects();
        for(var j=0;j<objs.Length;j++)
            allGameObjects.Remove(objs[j]);
        
    
    //移除父级不为null的对象
    int k=allGameObjects.Count;
    while(--k>=0)
        if(allGameObjects[k].transform.parent!=null)
            allGameObjects.RemoveAt(k);
        
    
    return allGameObjects.ToArray();
