有没有类似Monobehaviour中OnDestroy的方法

当切换场景时，displayObject对应的gamObject被销毁了，我想在销毁时做些Dispose和注销事件等操作，可以订阅哪个事件来处理被销毁时的逻辑吗？
因为有时候这边会遇到这样一些空异常的报错信息：
NullReferenceException: Object reference not set to an instance of an object

TimerManager.Update是自身订阅的一个事件，但是场景切换后由于没有注销，事件依然生效，displayObject也会相应，但是displayObject绑定的gameObject已经被销毁了，就空异常了
