:java400行能干啥?不如写个飞翔小鸟游戏吧_asbbv的博客-CSDN博客

Java 400行的代码可以实现许多不同的功能，具体取决于你想要实现什么样的功能。关于写一个飞翔小鸟游戏的想法，这是个很有趣的项目！下面是一个简单的示例代码，用于实现一个基本的飞翔小鸟游戏：

import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

public class FlappyBirdGame extends JFrame {

    private static final int WIDTH = 400;
    private static final int HEIGHT = 600;

    private int birdY;
    private int birdVelocity;

    public FlappyBirdGame() {
        setTitle("Flappy Bird");
        setSize(WIDTH, HEIGHT);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);

        birdY = HEIGHT / 2;
        birdVelocity = 0;

        addKeyListener(new KeyListener() {
            public void keyTyped(KeyEvent e) {}
            public void keyReleased(KeyEvent e) {}

            public void keyPressed(KeyEvent e) {
                if (e.getKeyCode() == KeyEvent.VK_SPACE) {
                    birdVelocity = -10;
                }
            }
        });

        Thread gameThread = new Thread(() -> {
            while (true) {
                birdVelocity += 1;
                birdY += birdVelocity;

                if (birdY >= HEIGHT - 30) { // 鸟碰到地板，游戏结束
                    JOptionPane.showMessageDialog(null, "Game Over!");
                    System.exit(0);
                }

                repaint();

                try {
                    Thread.sleep(20);
                } catch (InterruptedException ex) {
                    ex.printStackTrace();
                }
            }
        });

        gameThread.start();
    }

    public void paint(Graphics g) {
        g.setColor(Color.WHITE);
        g.fillRect(0, 0, WIDTH, HEIGHT);

        g.setColor(Color.RED);
        g.fillOval(WIDTH / 2 - 10, birdY - 10, 20, 20);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> {
            FlappyBirdGame game = new FlappyBirdGame();
            game.setVisible(true);
        });
    }
}

这只是一个简单的示例，你可以根据自己的需求进行扩展和修改。希望对你有帮助！
