我正在制作我的第一个游戏，上次我问这个问题时，我有点没解释清楚。基本上，下面是游戏的开场画面。我知道，不是很好，但这只是一个草稿。然后我也建立了游戏。 打开屏幕上有两个按钮，因为它是一个2人游戏。两个玩家必须单击准备好，然后我想编程结束，并启动第二个程序。但是我不知道该怎么做。
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class OpeningScreen {
JFrame frame;
JPanel main;
JButton ready1;
JButton ready2;
JPanel bottom;
JLabel label;
public OpeningScreen(){
UIManager.put("Button.background", Color.cyan);
UIManager.put("Button.foreground", Color.magenta);
UIManager.put("ToolTip.background", Color.magenta);
frame=new JFrame("Super Tuesday");
main=new JPanel();
ready1=new JButton("CLICK IF READY");
ready2=new JButton("CLICK IF READY");
label=new JLabel("SUPER TUESDAY");
bottom=new JPanel();
label.setFont(label.getFont().deriveFont(50.0f));
frame.setSize(480, 800);
frame.setLayout(new BorderLayout());
frame.add(main, BorderLayout.CENTER);
bottom.setLayout(new BorderLayout());
ready1.setToolTipText("CLICK ME TO START THE GAME");
ready2.setToolTipText("CLICK ME TO START THE GAME");

我希望这个替换第一个程序。我不确定如何开始这个，因为这是我在任何游戏中的第一次尝试，或者超出一个类程序的任何东西。
答案 0 :(得分：6)
不，你真的不想让java.awt.Applet替换JFrame，相信我。它们都用于两种截然不同的情况，而作为JFrame底层的Swing库已经过时了大约4年，作为java.awt.Applet基础的AWT库已经过时了大约20年。请远离Applet。
相反，您的GUI类应该适合创建JPanels，然后可以将其放置到JFrames或JDialogs，或JTabbedPanes中，或者在需要时通过CardLayouts交换。这将大大提高GUI编码的灵活性，事实上这就是我推荐的 - 你通过CardLayout交换视图。
此外 - 不要将MouseListeners用于JButton侦听器，而是使用ActionListeners。 MouseListeners不会响应空格键，如果按钮被禁用则不会被禁用，如果您基于mouseClicked方法的行为，则可能是反复无常的。使用适当的工具：ActionListeners，甚至更好的操作。
