                      .TimeoutFrame(120)
                      .Subscribe(_ => Debug.Log("mouse clicked"), e =>
                      {
                          Debug.LogFormat("excpetion frame count:{0}", Time.frameCount);
                      });

---

TakeUntilDestroy

每次按下⿏標左鍵，輸出 mouse clicked，將該腳本所在的 GameObject 銷燬後，點擊⿏標不再輸出

        Observable.EveryUpdate()
                      .Where(_ => Input.GetMouseButtonDown(0))
                      .TakeUntilDestroy(this)
                      .Subscribe(_ => Debug.Log("mouse clicked"));

---

TakeUntilDisable

每次按下⿏標左鍵，輸出 mouse clicked，將該腳本所在的 GameObject 隱藏掉後，點擊⿏標不再輸出
