限制相机旋转- Unity Clamp Quaternion

Question

我有这段代码可以让相机通过触摸屏的输入进行旋转，我需要将旋转锁定在特定范围内。我尝试使用“Math.Clamp”失败。有人可以帮助我吗？

我尝试输入此字符串，但视觉对象收到一条错误消息，显示“无法从 'UnityEngine.Quaternion' 转换为 'float'”

rotationY  = Mathf.Clamp(rotationY, -30, 30);

我把允许相机运行无限制的代码留给你。感谢大家的帮助

 private Touch touch;
    private Vector2 touchPosition;
    private Quaternion rotationY;
    private float rotateSpeedModifier = 0.01f;
    //public float yPos;

    // Update is called once per frame
    void Update()
    {
        if(Input.touchCount > 0)
        {
            
            touch = Input.GetTouch(0);

            if(touch.phase == TouchPhase.Moved)
            {
                    rotationY = Quaternion.Euler(0f, -touch.deltaPosition.x * rotateSpeedModifier, 0f);
                    transform.rotation = rotationY * transform.rotation;
                    Debug.Log(rotationY * transform.rotation);

            }
        }
    }

你不能夹住 Quaternion。

然而，您可以存储您已经旋转的角度的 float 并将其夹紧：

private Touch touch;
private Vector2 touchPosition;
private float rotationY;
private float rotateSpeedModifier = 0.01f;

private Quaternion originalRotation;

private void Start ()
{
    originalRotation = transform.rotation;
}

// Update is called once per frame
void Update()
{
    if(Input.touchCount > 0)
    {       
        touch = Input.GetTouch(0);

        if(touch.phase == TouchPhase.Moved)
        {
            rotationY -= touch.deltaPosition.x * rotateSpeedModifier;
            rotationY = Mathf.Clamp(rotationY, -30, 30);

            transform.rotation = originalRotation * Quaternion.Euler(0, rotationY, 0);
        }
    }
}
