• 代码实现

1，控制移动
  // Update is called once per frame
    void Update()
    {
        horizontal = analogLeft.localPosition.x;
        vertical = analogLeft.localPosition.y;

        //hor = 遥感脚本中的localPosition.x
        float hor = Horizontal;
        //hor = 遥感脚本中的localPosition.y
        float ver = Vertical;

        Vector3 direction = new Vector3(hor, 0, ver);

        if (direction != Vector3.zero)
        {
            //控制移动
            float newSpeed = Mathf.Lerp(ani.GetFloat("Speed"), 3, Time.deltaTime * 5);
            ani.SetFloat("Speed", newSpeed);
            //控制旋转
            ani.transform.rotation = Quaternion.Lerp(ani.transform.rotation, Quaternion.LookRotation(direction), Time.deltaTime * 10);
        }
        else
        {
            //停止移动
            float newSpeed = Mathf.Lerp(ani.GetFloat("Speed"), 0, Time.deltaTime * 5);
            ani.SetFloat("Speed", 0);
        }
    }

    /// 

    /// 当鼠标开始拖拽时
    /// 
    /// 
    public void OnDrag(PointerEventData eventData)
    {
        //获取鼠标位置与初始位置之间的向量
        Vector2 oppsitionVec = eventData.position - moveBackPos;
        //获取向量的长度
        float distance = Vector3.Magnitude(oppsitionVec);
        //最小值与最大值之间取半径
        float radius = Mathf.Clamp(distance, 0, maxRadius);
        //限制半径长度
        analogLeft.position = moveBackPos + oppsitionVec.normalized * radius;

    }

2，控制相机旋转
 void RotateAroundCube()
    {

        float x = 0;
        float y = 0;
#if  !UNITY_STANDALONE_WIN
        bool isright = false;
        foreach (var ta in Input.touches)
        {
            if (ta.position.x > (Screen.width / 2))
            {
                if (lastpoint != Vector3.zero)
                {
                    x = ta.position.x - lastpoint.x;
                    y = ta.position.y - lastpoint.y;
                }
                lastpoint = new Vector3(ta.position.x, ta.position.y);
                isright = true;
                break;
            }
        }
        if (Input.touches.Length <= 0)
        {
            lastpoint = Vector3.zero;
            x = 0;
            y = 0;
        }
        if (!isright)
        {
            lastpoint = Vector3.zero;
            x = 0;
            y = 0;
        }
#endif

#if UNITY_STANDALONE_WIN
        if (Input.GetMouseButton(0))
        {
            x = Input.GetAxis("Mouse X");
            y = Input.GetAxis("Mouse Y");
            rotateX += x * 2f;
            // Debug.Log("rotateX" + rotateX);
            rotateY -= y * 2f;
            // Debug.Log("rotateY" + rotateY);
        }
#else
            rotateX += x * 1f * Time.deltaTime;
            Debug.Log("rotateX" + rotateX);
            rotateY -= y * 1.1f * Time.deltaTime;
            Debug.Log("rotateY" + rotateY);
#endif
        //防止出现翻转现象
        rotateY = Mathf.Clamp(rotateY, -30, 35);
        //rotateZ += Input.GetAxis("Mouse ScrollWheel") * 5;
        //rotateZ = Mathf.Clamp(rotateZ, -12, -2);
        transform.position = target.transform.position +
             Quaternion.Euler(rotateY, rotateX, 0) * new Vector3(0, 1, rotateZ);
        transform.LookAt(target.transform);
        offset = transform.position - target.position;
        transform.position = offset + target.transform.position;
        
    }
}
