if(Input.mousePosition.x>= 960)
        {
            logoCamera.transform.Translate(-Vector3.right * Time.deltaTime * cameraSpeed);
        }
        else if (Input.mousePosition.x <= 960)
        {
            logoCamera.transform.Translate(Vector3.right * Time.deltaTime * cameraSpeed);
        }
        else if (Input.mousePosition.y >= 540)
        {
            logoCamera.transform.Translate(-Vector3.up * Time.deltaTime * cameraSpeed);
        }
        else if (Input.mousePosition.y <= 540)
        {
            logoCamera.transform.Translate(Vector3.up * Time.deltaTime * cameraSpeed);
        }

这段只能水平移动,如果还想要垂直移动要怎么改?
