好的，所以我在这里得到了这个问题。我正在为我的游戏制作一个启动器，我得到了一切正常工作，除非我试图让Play按钮工作它工作正常并执行我为它设置的命令，除了它没有打开文件我设置它打开按钮点击。 （JAVA代码） 下面是启动器的代码：
private static final long serialVersionUID = 1L;
private JPanel window = new JPanel();
private JButton Play, Options, Update, Multiplayer, Quit;
private Rectangle rPlay, rOptions, rUpdate, rMultiplayer, rQuit;
private int width = 240;
private int height = 320;
public Launcher(){
try{
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e){
e.printStackTrace();
}
setTitle("Questor Launcher");
setSize(new Dimension(800, 600));
setDefaultCloseOperation(EXIT_ON_CLOSE);
getContentPane().add(window);
setLocationRelativeTo(null);
setResizable(true);
setVisible(true);
window.setLayout(null);
drawButtons();
}
private void drawButtons(){
Play = new JButton ("Play");
rPlay = new Rectangle(650, 500, 80, 40);
Play.setBounds(rPlay);
window.add(Play);
Options = new JButton ("Options");
rOptions = new Rectangle(550, 500, 80, 40);
Options.setBounds(rOptions);
window.add(Options);
Update = new JButton ("Update");
rUpdate = new Rectangle(450, 500, 80, 40);
Update.setBounds(rUpdate);
window.add(Update);
Multiplayer = new JButton ("Multiplayer");
rMultiplayer = new Rectangle(300, 500, 130, 40);
Multiplayer.setBounds(rMultiplayer);
window.add(Multiplayer);
Quit = new JButton ("Quit");
rQuit = new Rectangle(200, 500, 80, 40);
Quit.setBounds(rQuit);
window.add(Quit);
Play.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a) {
System.out.println("Entering Game...");
dispose();
new RunGame();
}
});
Options.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a) {
System.out.println("Entering Options Menu...");
}
});
Update.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a) {
System.out.println("Opening browser to Questor.weebly.com/questor...");
}
});
Multiplayer.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a) {
}
});
Quit.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent a) {
System.out.println("Quiting Game...");
System.exit(0);
}
});
}}
继承RunGame文件的代码：
private static Game game = new Game();
public static final boolean DEBUG = false;
@Override
public void init() {
setLayout(new BorderLayout());
add(game, BorderLayout.CENTER);
setMaximumSize(Game.DIMENSIONS);
setMinimumSize(Game.DIMENSIONS);
setPreferredSize(Game.DIMENSIONS);
game.debug = DEBUG;
game.isApplet = true;
}
@Override
public void start() {
game.start();
}
@Override
public void stop() {
game.stop();
}
public static void main(String[] args) {
game.setMinimumSize(Game.DIMENSIONS);
game.setMaximumSize(Game.DIMENSIONS);
game.setPreferredSize(Game.DIMENSIONS);
game.frame = new JFrame(Game.NAME);
game.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
game.frame.setLayout(new BorderLayout());
game.frame.add(game, BorderLayout.CENTER);
game.frame.pack();
game.frame.setResizable(false);
game.frame.setLocationRelativeTo(null);
game.frame.setVisible(true);
game.windowHandler = new WindowHandler(game);
game.debug = DEBUG;
game.start();
}
}
最后但并非最不重要的游戏文件代码：
