c# - 为什么 FindObjectOfType(MyType) 找不到任何东西？

Question

为什么会得到如下日志？

• 启动OpponentMotionReceiver
• 未找到运动接收器
• 正确

---

    public class ScoreAnimation : MonoBehaviour
    {
        private OpponentMotionReceiver cachedObject;

        private void Start()
        {
            cachedObject = FindObjectOfType<OpponentMotionReceiver>();
        }

        private void OnDestroy()
        {
                var motionReceiver = FindObjectOfType<OpponentMotionReceiver>();

                if (motionReceiver == null)
                {
                    Debug.Log("motion receiver not found");
                }

                if(cachedObject != null)
                {
                    //prints true, another proof that the gameObject is active
                    Debug.Log(cachedObject.gameObject.activeInHierarchy);
                }
        }
    }

public class OpponentMotionReceiver : MonoBehaviour
    {
        private void Start()
        {
            Debug.Log("Start OpponentMotionReceiver");
        }

        private void OnDisable()
        {
            Debug.Log("OnDisable OpponentMotionReceiver");
        }

        private void OnDestroy()
        {
            Debug.Log("OnDestroy OpponentMotionReceiver");
        }
    }

附言这是代码的极其简化的版本，因此其余部分不会造成混淆。如果您需要更多详细信息，我很乐意回答您!

改变场景。只有在那个时候团结才会表现得那样。无论我们正在寻找的对象是否处于事件状态，简单的 FindObjectOfType 在游戏周期的这一点上不起作用。
