Unity2d 全屏與窗口的切換

核心代碼

    public void ResolutionSet()
    {
        if (ResoType % 2 == 0)
        {
            Screen.SetResolution(1155, 763, false, 60);
            ResoType++;
            ResoText.text = "窗口";
            return;
        }
        if (ResoType % 2 == 1)
        {
            Screen.SetResolution(2160, 1440, true, 60);
            ResoType++;
            ResoText.text = "全屏";
            return;
        }
    }
