        {
            SetFullScreen();
        }
    }

    public void SetFullScreen()
    {
        //获取设置当前屏幕分辩率 
        Resolution[] resolutions = Screen.resolutions;
        //设置当前分辨率 
        Screen.SetResolution(resolutions[resolutions.Length - 1].width, resolutions[resolutions.Length - 1].height, true);

        Screen.fullScreen = true;  //设置成全屏

    }
