项目在切换场景或者是关闭Unity运行界面的时候，出现Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)错误。原因是我在一个不销毁的单利里面，定义了一个事件，在外部去注册这个事件。
/// <summary> /// 数据改变通知的事件 /// </summary> public GameDataDel GameDataHandle;
public static SaveGameData _instance; public static SaveGameData Instance { get { if (_applicationIsQuitting) { return null; } if (_instance == null) { GameObject go = new GameObject("SaveGameData"); SaveGameData saveGameData = go.AddComponent<SaveGameData>(); DontDestroyOnLoad(go); _instance = saveGameData; } return _instance; } }
外面事件的注册
private void OnEnable() { Ctr_PlayerInfo.OnShowLifeNumEve += OnFreshLifeNum; SaveGameData.Instance.GameDataHandle += OnFresh; } private void OnDisable() { if (Ctr_PlayerInfo.OnShowLifeNumEve != null) { Ctr_PlayerInfo.OnShowLifeNumEve -= OnFreshLifeNum; } if (SaveGameData.Instance!= null) { SaveGameData.Instance.GameDataHandle -= OnFresh; } }
当我退出时，应用程序对象会以随机顺序被销毁。因此，如果gameManager实例在任何OnDisable()方法之前被销毁，那么在应用程序退出导致错误后，将创建gameManager类的新实例!!为了解决这个错误，我做了以下修改:
public static SaveGameData _instance;
private static bool _applicationIsQuitting = false;
public static SaveGameData Instance
{
get
{
if (_applicationIsQuitting)
{
return null;
}
if (_instance == null)
{
GameObject go = new GameObject("SaveGameData");
SaveGameData saveGameData = go.AddComponent<SaveGameData>();
DontDestroyOnLoad(go);
_instance = saveGameData;
}
return _instance;
}
}
public void OnDestroy()
{
_applicationIsQuitting = true;
}
