如何限制 Y 軸上的旋轉，使玩家無法在 Unity 中旋轉相機 360？

Question

我有一個即將到來的項目，我必須在周一提交，這是我必須解決的最后一個錯誤。 如果有人幫助我並教我如何應用軸限制器，那就太好了。 提前謝謝大家。 問題是相機可以旋轉 360 度，這是我正在從事的項目唯一留下的錯誤。

已編輯。 如果我理解正確 - -rotY * Time.deltaTime使您的相機在 Y 軸上旋轉。 您可以像這樣將 rotY 值限制在 90 到 180 之間：

 void CameraRotation(GameObject cam, float rotX, float rotY){ 
    if(rotY > 180f /*Some value to limit*/)
    {
      rotY = 180f;
    }       
    else if(rotY < 90f /*Some value to limit*/ )
    {
      rotY = 90f;
    }
     transform.Rotate (0, rotX * Time.deltaTime, 0);
     cam.transform.Rotate (-rotY * Time.deltaTime, 0, 0);
 }

而且，我認為 transform.Rotate 使用 x,y,z 值。 為什么你的cam.transform.Rotate在它的 x 軸上以-rotY (y) 值旋轉？
