我有三节课。游戏菜单的框架，当播放按钮时， 按下包含Game的框架类应该播放。主类创建Menu类的对象。但问题是当我按下播放按钮时它会变成白色，经过一段时间后它表示你的分数为0且游戏结束。请帮助我解决这个问题我已经尝试了所有的事情。

包含游戏菜单的框架，当我们按下播放按钮时，游戏应该开始。
import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class GameMenu extends JFrame {
private JButton play;
private JButton exit;
private JButton about;
private JButton credit;
private ImageIcon img;
private JLabel imgLabel;
private JPanel panel;
private float h = (float) 0.333;
private float b = (float) 0.600;
private float s = 1;
boolean runCheck = false;
public GameFrame frame;
GameMenu() {
setLayout(null);
setResizable(false);
panel = new JPanel();
panel.setLayout(null);
panel.setSize(760, 700);
panel.setBackground(Color.getHSBColor(h, s, b));
add(panel);
play = new JButton("PLAY");
play.setSize(100, 50);
play.setLocation(360, 400);
panel.add(play);
about = new JButton("ABOUT");
about.setSize(play.getSize());
about.setLocation(play.getX(), play.getY() + play.getHeight() + 50);
panel.add(about);
exit = new JButton("EXIT");
exit.setSize(play.getSize());
exit.setLocation(about.getX() + about.getWidth() + 50, about.getY());
panel.add(exit);
credit = new JButton("CREDIT");
credit.setSize(play.getSize());
credit.setLocation(about.getX() - about.getWidth() - 50, about.getY());
panel.add(credit);
img = new ImageIcon("C:\\Users\\Ghulam Haider\\Downloads\\b.jpg");
imgLabel = new JLabel(img);
imgLabel.setSize(imgLabel.getPreferredSize());
imgLabel.setLocation(230, 45);
panel.add(imgLabel);
mouseListener mouse = new mouseListener();
Action action = new Action();
play.addMouseListener(mouse);
}
private class Action implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {}
}
private class mouseListener implements MouseListener, Runnable {
@Override
public void mouseClicked(MouseEvent get) {}
@Override
public void mousePressed(MouseEvent e) {
if (e.getSource() == play) {
frame = new GameFrame();
frame.setSize(760, 700);
frame.setLocation(200, 25);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
frame.setVisible(true);
frame.Run();
// end of while
}
}
@Override
public void mouseReleased(MouseEvent e) {}
@Override
public void mouseEntered(MouseEvent e) {}
@Override
public void mouseExited(MouseEvent e) {}
@Override
public void run() {
frame.Run();
// end of while
}
}
}
最后调用菜单框的主类。
import javax.swing.JFrame;
public class RunGame {
public static void main(String args[]) {
GameMenu menu = new GameMenu();
menu.setSize(760, 700);
menu.setLocation(200, 25);
menu.setVisible(true);
menu.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
答案 0 :(得分：2)
但问题是当我按下播放按钮时会变成白色，经过一段时间后它会说你的分数为0且游戏结束了。
你在EDT上调用GameFrame.Run方法 - Swing是单线程的，所有绘画，事件等都在EDT上运行。如果你有阻止它的东西（例如在{1}}方法上调用EDT上的Thread.sleep），那么这些都不会发生。而是创建Thread或使用Timer
其他一些建议：
JFrame方法绘制到JPanel - 绘制到paintComponent。 null布局。为您寻找的布局选择合适的LayoutManager。 ActionListener而不是MouseListener mouselistener）开头，方法名称以小写开头。避免与API名称发生任何潜在的命名冲突答案 1 :(得分：0)
包含finish（）的if语句未被括号括起。因此，在它看到条件后，它只是移动并运行finish（）
if((y+20>d&&x+20>c&&y<d+6&&x<c+60))//Control the Direction as well as Collision of the Grey Ball From Rectangle
b=-s;
y=y+b;
finish();//Call the Method of Finish
所以每次调用run方法时都会终止，因为也总是调用finish（）。
尝试围绕if语句，以便在语句为true时仅调用finish（）。或者写一个单独的if语句，当条件满足时，调用finish（）。
