我是一個嘗試創建遊戲的初學者。遊戲是空的，我沒有開始寫它。遊戲的主菜單
我的問題是：當我點擊開始按鈕時，我想在同一幀中啓動遊戲，但是當我點擊開始時，此代碼會打開另一個菜單框架，並在原始框架中將刪除面板。
我該如何做這個簡單的菜單？

import java.awt.*;
import java.awt.event.*;

import panelimage.Image;
public class Project0 extends JFrame{
private static final long serialVersionUID = 1L;
private Game JPanelGame;
private Image MainMenu = new Image(new File("src/img/menu_background.jpg"));
JButton start = new JButton("START GAME"), exit = new JButton ("LEAVE GAME");
public Project0() {
super();
initFrame();
initMenu();
this.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent evt) {
JPanelGame.keyPressed(evt);
}
public void keyReleased(KeyEvent evt) {
JPanelGame.keyReleased(evt);
}
});
}
private void initFrame() {
setResizable(false);
setBounds(new Rectangle(400, 400, 600, 400));
MainMenu.setLayout(new BorderLayout());
}
private void initMenu() {
initButtons();
MainMenu.setLayout(null);
MainMenu.add(start);
MainMenu.add(exit);
add(MainMenu);
setContentPane(MainMenu);
setTitle("Project0");
}
private void initButtons() {
start.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e){
JPanelGame = new Game();
remove(MainMenu);
add(JPanelGame, BorderLayout.CENTER);
setContentPane(JPanelGame);
invalidate(); validate();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
Project0 Game = new Project0();
Game.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Game.setVisible(true);
}
});
}
});
start.setLocation(225,100);
start.setSize(150,50);
exit.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e){
System.exit(0);
}
});
exit.setLocation(225,200);
exit.setSize(150,50);
}
public static void main(String[] args) {
Project0 Game = new Project0();
Game.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Game.setVisible(true);
}
}
這個框架將開始

}當你調用SwingUtilities.invokeLater()您的按鈕的動作監聽器裏
