如何旋转播放器？

Question

我尝试旋转播放器的相机，但下面的代码不起作用。我用它来保存/加载游戏功能

public void ButtonSave()
 {
     PlayerPrefs.SetFloat("transform position x" + currentActiveSlot, playerTransform.position.x);
     PlayerPrefs.SetFloat("transform position y" + currentActiveSlot, playerTransform.position.y);
     PlayerPrefs.SetFloat("transform position z" + currentActiveSlot, playerTransform.position.z);

     // Save all 4 values for the quaternion
     PlayerPrefs.SetFloat("transform rotation x" + currentActiveSlot, playerTransform.rotation.x);
     PlayerPrefs.SetFloat("transform rotation y" + currentActiveSlot, playerTransform.rotation.y);
     PlayerPrefs.SetFloat("transform rotation z" + currentActiveSlot, playerTransform.rotation.z);
     PlayerPrefs.SetFloat("transform rotation w" + currentActiveSlot, playerTransform.rotation.w);

     PlayerPrefs.Save();
 }
 public void ButtonLoad() // call via canvas UI load button
 {
     // this work
     playerTransform.position = new Vector3(
             PlayerPrefs.GetFloat("transform position x" + currentActiveSlot),
             PlayerPrefs.GetFloat("transform position y" + currentActiveSlot),
             PlayerPrefs.GetFloat("transform position z" + currentActiveSlot));

     // this don't work
     Quaternion savedRotation = new Quaternion(
             PlayerPrefs.GetFloat("transform rotation x" + currentActiveSlot),
             PlayerPrefs.GetFloat("transform rotation y" + currentActiveSlot),
             PlayerPrefs.GetFloat("transform rotation z" + currentActiveSlot),
             PlayerPrefs.GetFloat("transform rotation w" + currentActiveSlot));
     playerTransform.rotation = savedRotation;    
 }

尝试下面的组合，但它们也不起作用

playerTransform.Rotate(new Vector3(1, 2, 3));
playerTransform.Rotate(1, 2, 3);
playerTransform.eulerAngles = new Vector3(1, 2, 3);

开始模拟后，我无法用手旋转
