我创建了一个关卡电脑游戏，我想添加另一个关卡。

这是主要的：

public class Main extends JDialog
{   

    private static final long serialVersionUID = 1L;
    protected static TimerThread timerThread;
    static JStatusBar statusBar = new JStatusBar();
    private static JFrame frame;
    private static final int FRAME_LOCATION_X = 300;
    private static final int FRAME_LOCATION_Y = 50;
    private static final int FRAME_SIZE_X = 850; // animator's target frames per second
    private static final int FRAME_SIZE_Y = 700; // animator's target frames per second
    private static final String WorldName = "FPS 2013 CG Project";
    private static final String HARD_TARGET = "src/res/target.jpg";
    private static final String runningOut = "Time is running out - you have : ";

    static int interval;
    static Timer timer1;
    static JLabel changingLabel1 = null;


    /**
     *  NEW
     */

    private static Timer timer;
    private static int count = 60;

    private static ActionListener timerAction = new ActionListener()
    {
        public void actionPerformed(ActionEvent ae)
        {
            count--;
            if (count == 0)
                timer.stop();
            changingLabel1.setText(runningOut + count + " seconds"); 
        }
    };


    public static void exitProcedure() {
        timerThread.setRunning(false);
        System.exit(0);
    }


        /**

                this.isRunning = isRunning;
            }

        }




    public static void main(String[] args) 
    {

           SwingUtilities.invokeLater(new Runnable() 
            {
                @Override

                    Toolkit t = Toolkit.getDefaultToolkit();

                    try 
                    {
                        originalImage = ImageIO.read(new File(HARD_TARGET));
                    } 

                    catch (Exception e1) {e1.printStackTrace();}
                    Cursor newCursor = t.createCustomCursor(originalImage, new Point(0, 0), "none"); 

                    frame.setCursor(newCursor);
                    frame.setLocation(FRAME_LOCATION_X, FRAME_LOCATION_Y);
                    frame.add(myCanvas);
                    frame.setSize(FRAME_SIZE_X, FRAME_SIZE_Y);
                    frame.addWindowListener(new WindowAdapter()

                    {
                        @Override
                        public void windowClosing(WindowEvent e) 
                        {
                            new Thread() 
                            {
                                 @Override
                                 public void run() 
                                 {
                                     animator.stop();
                                     System.exit(0);
                                 }
                            }.start();
                        }
                    });

                    frame.setVisible(true);
                    animator.start();
                    myCanvas.requestFocus();
                    myCanvas.setFocusable(true);
                }
            });
    }
}

这个 Main 函数使用类 Renderer ，即

class Renderer extends GLCanvas implements GLEventListener, KeyListener ,MouseListener ,MouseMotionListener {...}

而那个班级拥有游戏的第一级。

如您所见，我也在使用JFrameand JOGL 1.0。

我的问题是：完成第一级后如何重置 JFrame？显然我不能使用System.exit(0); ，因为它会退出整个程序。

我想要的是转到另一个拥有第二级的班级。

我怎么能不退出System.exit(0);呢？

谢谢

通过使用remove()，您可以有效地停止面板。然后只需创建一个新的JFrame即可add()。考虑让JFrame创作成为它自己的功能，这样如果你这样做，你就不必继续重写它。

好吧，您可以使用frame.dispose()然后创建具有下一个级别的相同 JFrame ...

我建议你重组你的代码......你的 Main 类应该只包含 main 方法，并且你应该从哪里开始游戏，它将位于另一个包含 JFrame 和 Thread 的类中......
