Java屏幕分辨率更改

Question

我正在关注 Youtube 上 thenewboston 的 Java 游戏开发系列教程。我现在可以制作全屏窗口，但分辨率拒绝调整为 800x600。我已经测试了 vc，一个 GraphicsEnvironment.getDefaultScreenDevice 对象，和 dm，一个 DisplayMode，它们似乎不是问题所在。我正在运行雪豹。有什么想法吗？

if(dm != null && vc.isDisplayChangeSupported()){
        try{
            vc.setDisplayMode(dm);
            System.out.println("Display mode set");
        }catch(Exception ex){System.out.println("Despite the vc saying it is display change supported and the DM is not null, something went wrong");}

    }
}

将此代码添加到您的 Core.java(或 GameClient.java)类中。问题可能是您没有将所需的 DM[] 参数传递给您的 ScreenManager.java 类。

private static final DisplayMode modes[] = { //common monitor DMs 
    new DisplayMode(1366,768,32, DisplayMode.REFRESH_RATE_UNKNOWN), //1366x768px w/32-bit depth
    new DisplayMode(1366,768,24, DisplayMode.REFRESH_RATE_UNKNOWN), //    '      w/24-bit depth
    new DisplayMode(1366,768,16, DisplayMode.REFRESH_RATE_UNKNOWN), //    '      w/16-bit depth     
    new DisplayMode(800,600,32, DisplayMode.REFRESH_RATE_UNKNOWN),  //800x600px  w/32-bit depth
    new DisplayMode(800,600,24, DisplayMode.REFRESH_RATE_UNKNOWN),  //    '      w/24-bit depth
    new DisplayMode(800,600,16, DisplayMode.REFRESH_RATE_UNKNOWN),  //    '      w/16-bit depth 
    new DisplayMode(640,480,32, DisplayMode.REFRESH_RATE_UNKNOWN),  //640x480px  w/32-bit depth
    new DisplayMode(640,480,24, DisplayMode.REFRESH_RATE_UNKNOWN),  //    '      w/24-bit depth
    new DisplayMode(640,480,16, DisplayMode.REFRESH_RATE_UNKNOWN),  //    '      w/16-bit depth
};

我假设错误与您的 public void setFullScreen(DisplayMode dm) 方法有关。在这种情况下，此方法的完整语法为:

/*****************************************************************************
 * @description: Creates window for program to run in, using appropriate DM
 * @param DisplayMode dm 
 */
    public void setFullScreen(DisplayMode dm){
        JFrame f = new JFrame();
        f.setUndecorated(true); //no titlebars/scroll bars etc.
        f.setIgnoreRepaint(true);
        f.setResizable(false); //user cannot resize window
        vc.setFullScreenWindow(f);

        if(dm!=null && vc.isDisplayChangeSupported()){ //if DM is changeable
            try {
                vc.setDisplayMode(dm);
            } catch (Exception e){/*Catch 'em all*/}
        }
        f.createBufferStrategy(2); //set # of screen buffers to 2
    }//setFullScreen()
