我使用脚本来用鼠标旋转相机，并且希望将其转换为触摸方式。我希望我的相机仅在触摸屏幕时旋转。该游戏具有第一个玩家控制器。请帮我把它做成触摸屏

获取第一个Touch，然后使用touch.deltaPosition查找自上次更新以来触摸已移动了多少。然后，您可以根据屏幕大小和灵敏度进行缩放。

void Update()
{
    if(Input.touchCount > 0) {
        Touch touch = Input.GetTouch(0);
        float turnAngleChange = (touch.deltaPosition.x / Screen.width) * sensitivityX; 
        float pitchAngleChange = (touch.deltaPosition.y / Screen.height) * sensitivityY;

        // Handle any pitch rotation
        if (axes == RotationAxes.MouseXAndY || axes == RotationAxes.MouseY) {
            rotationY = Mathf.Clamp(rotationY+pitchAngleChange, minimumY, maximumY);
            transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0f));
        }

        // Handle any turn rotation
        if (axes == RotationAxes.MouseXAndY || axes == RotationAxes.MouseX) {
            transform.Rotate(0f, turnAngleChange , 0f);
        }
    }
}

作为旁注，即使俯仰旋转实际上是沿rotationY轴的旋转，也可以称之为俯仰旋转x，反之亦然。
