Rotate3dObj在Update中调用，脚本挂在需要旋转的物体上即可

private float m_deltaX=0;private float m_deltaY=0;private void Rotate3dObj(){#if UNITY_EDITOR    if (Input.GetMouseButton(0))#else    if(1 == Input.touchCount && Input.touches[0] == TouchPhase.Moved)#endif    {        m_deltaX = Input.GetAxis("Mouse X");        m_deltaY = Input.GetAxis("Mouse Y");    }    if (m_deltaX > 0)    {        m_deltaX -= Time.deltaTime;        if (m_deltaX < 0)            m_deltaX = 0;    }    else    {        m_deltaX += Time.deltaTime;        if (m_deltaX > 0)            m_deltaX = 0;    }    if (m_deltaY > 0)    {        m_deltaY -= Time.deltaTime;        if (m_deltaY < 0)        m_deltaY = 0;    }    else    {        m_deltaY += Time.deltaTime;        if (m_deltaY > 0)            m_deltaY = 0;    }    gameObject.transform.Rotate(new Vector3(0, -1, 0), m_deltaX * 10, Space.World);    gameObject.transform.Rotate(new Vector3(1, 0, 0), m_deltaY * 10, Space.World);}
