以下是一个简单的Java涂鸦跳跃游戏代码示例:

import java.awt.*;import java.awt.event.*;import javax.swing.*;public class DoodleJump extends JPanel implements ActionListener {    private static final int WIDTH = 400;    private static final int HEIGHT = 600;    private static final int GROUND = 550;    private static final int PLAYER_SIZE = 25;    private static final int PLATFORM_WIDTH = 50;    private static final int PLATFORM_HEIGHT = 10;    private static final int PLATFORM_GAP = 200;    private static final int PLATFORM_COUNT = 6;    private static final int GRAVITY = 2;    private static final int JUMP_HEIGHT = 30;    private Timer timer;    private int playerX;    private int playerY;    private int velocityY;    private boolean isJumping;    private Platform[] platforms;    public DoodleJump() {        setPreferredSize(new Dimension(WIDTH, HEIGHT));        setBackground(Color.BLACK);        setFocusable(true);        addKeyListener(new KeyAdapter() {            @Override            public void keyPressed(KeyEvent e) {                if (e.getKeyCode() == KeyEvent.VK_SPACE) {                    if (!isJumping) {                        isJumping = true;                        velocityY = -JUMP_HEIGHT;                    }                }            }        });        playerX = WIDTH / 2;        playerY = GROUND;        velocityY = 0;        isJumping = false;        platforms = new Platform[PLATFORM_COUNT];        for (int i = 0; i < PLATFORM_COUNT; i++) {            platforms[i] = new Platform((int) (Math.random() * (WIDTH - PLATFORM_WIDTH)), GROUND - i * PLATFORM_GAP);        }        timer = new Timer(10, this);        timer.start();    }    @Override    protected void paintComponent(Graphics g) {        super.paintComponent(g);        g.setColor(Color.WHITE);        g.fillOval(playerX - PLAYER_SIZE / 2, playerY - PLAYER_SIZE / 2, PLAYER_SIZE, PLAYER_SIZE);        for (Platform platform : platforms) {            g.fillRect(platform.getX(), platform.getY(), PLATFORM_WIDTH, PLATFORM_HEIGHT);        }    }    public void actionPerformed(ActionEvent e) {        playerY += velocityY;        if (isJumping) {            velocityY += GRAVITY;        }        if (playerY > GROUND) {            playerY = GROUND;            velocityY = 0;            isJumping = false;        }        for (Platform platform : platforms) {            if (playerY + PLAYER_SIZE / 2 > platform.getY() && playerY + PLAYER_SIZE / 2 < platform.getY() + PLATFORM_HEIGHT                    && playerX + PLAYER_SIZE / 2 > platform.getX() && playerX - PLAYER_SIZE / 2 < platform.getX() + PLATFORM_WIDTH) {                playerY = platform.getY() - PLAYER_SIZE / 2;                velocityY = 0;                isJumping = false;            }        }        for (Platform platform : platforms) {            platform.setY(platform.getY() + GRAVITY);            if (platform.getY() > HEIGHT) {                platform.setY(platform.getY() - PLATFORM_GAP * PLATFORM_COUNT);                platform.setX((int) (Math.random() * (WIDTH - PLATFORM_WIDTH)));            }        }        repaint();    }    public static void main(String[] args) {        JFrame frame = new JFrame("Doodle Jump");        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);        frame.getContentPane().add(new DoodleJump());        frame.pack();        frame.setLocationRelativeTo(null);        frame.setVisible(true);    }    private class Platform {        private int x;        private int y;        public Platform(int x, int y) {            this.x = x;            this.y = y;        }        public int getX() {            return x;        }        public int getY() {            return y;        }        public void setX(int x) {            this.x = x;        }        public void setY(int y) {            this.y = y;        }    }}

这是一个简单的涂鸦跳跃游戏,玩家通过控制跳跃的小涂鸦在不断生成的平台上往上跳跃。玩家按下空格键时,小涂鸦会向上跳跃,玩家需要控制小涂鸦跳到平台上,如果没有跳到平台上就会掉下来,游戏结束。平台会不断从上面生成,玩家需要不断跳跃上去,直到无法继续跳跃
