使用Java实现一个贪吃蛇游戏(运行即可玩)

public class SnakeGame extends JFrame {
    private int gameSize = 10; // 游戏格子的大小
    private int gameWidth = 50; // 游戏界面宽度，格子数量
    private int gameHeight = 50; // 游戏界面高度，格子数量
    private int direction = KeyEvent.VK_RIGHT; // 初始方向向右

    private List<Point> snake; // 蛇的身体
    private Point food; // 食物

    public SnakeGame() {
        setTitle("贪吃蛇游戏");
        setSize(gameWidth * gameSize, gameHeight * gameSize);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setResizable(false);

        snake = new ArrayList<>();
        snake.add(new Point(0, 0)); // 初始位置在左上角

        generateFood(); // 生成食物

        addKeyListener(new KeyAdapter() {
            @Override
            public void keyPressed(KeyEvent e) {
                int key = e.getKeyCode();

                // 判断按下的方向键与蛇的当前方向是否相反，防止蛇倒退
                if ((key == KeyEvent.VK_LEFT && direction != KeyEvent.VK_RIGHT) ||
                        (key == KeyEvent.VK_RIGHT && direction != KeyEvent.VK_LEFT) ||
                        (key == KeyEvent.VK_UP && direction != KeyEvent.VK_DOWN) ||
                        (key == KeyEvent.VK_DOWN && direction != KeyEvent.VK_UP)) {
                    direction = key;
                }
            }
        });

        Timer timer = new Timer(200, e -> { // 每200毫秒触发一次定时器
            move(); // 移动蛇身
            checkCollision(); // 检测碰撞
            repaint(); // 重绘界面
        });
        timer.start();
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);

        // 画蛇
        for (Point point : snake) {
            drawSquare(g, point, Color.GREEN);
        }

        // 画食物
        drawSquare(g, food, Color.RED);
    }

    private void drawSquare(Graphics g, Point point, Color color) {
        g.setColor(color);
        g.fillRect(point.x * gameSize, point.y * gameSize, gameSize, gameSize);
    }

    private void move() {
        Point head = new Point(snake.get(0)); // 蛇头

        // 根据方向移动蛇头位置
        if (direction == KeyEvent.VK_LEFT) {
            head.x--;
        } else if (direction == KeyEvent.VK_RIGHT) {
            head.x++;
        } else if (direction == KeyEvent.VK_UP) {
            head.y--;
        } else if (direction == KeyEvent.VK_DOWN) {
            head.y++;
        }

        snake.add(0, head); // 将新的蛇头加入蛇身

        // 如果新的蛇头与食物位置相同，则增加蛇的长度并生成新的食物
        if (head.equals(food)) {
            generateFood();
        } else {
            snake.remove(snake.size() - 1); // 否则移除蛇尾
        }
    }

    private void generateFood() {
        Random random = new Random();
        int x, y;

        // 随机生成食物的位置，保证不与蛇身重叠
        do {
            x = random.nextInt(gameWidth);
            y = random.nextInt(gameHeight);
        } while (snake.contains(new Point(x, y)));

        food = new Point(x, y);
    }

    private void checkCollision() {
        Point head = snake.get(0);

        // 判断是否与边界碰撞
        if (head.x < 0 || head.x >= gameWidth || head.y < 0 || head.y >= gameHeight) {
            gameOver();
        }

        // 判断是否与自身碰撞
        for (int i = 1; i < snake.size(); i++) {
            if (head.equals(snake.get(i))) {
                gameOver();
            }
        }
    }

    private void gameOver() {
        JOptionPane.showMessageDialog(this, "Game Over");
        System.exit(0);
    }

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

效果如图：(代码中有注释，可以自行更改，方向键移动，方向键下为开始游戏)
