用Java实现一个超级玛丽小游戏，实现基本的游戏操作

好的，我可以为您提供一个简单的Java代码示例，实现基本的超级玛丽小游戏操作。

在这个小游戏中，玩家需要控制超级玛丽来躲避障碍物并收集金币。以下是代码示例：

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class SuperMario extends JPanel implements KeyListener, Runnable {

    private static final long serialVersionUID = 1L;
    private static final int WIDTH = 800;
    private static final int HEIGHT = 600;
    private static final int GROUND = 500;
    private static final int SPEED = 10;

    private boolean isRunning = true;
    private boolean isJumping = false;
    private int x = 0;
    private int y = GROUND;
    private int jumpHeight = 100;
    private int jumpCount = 0;
    private Image mario = new ImageIcon("mario.png").getImage();
    private Image background = new ImageIcon("background.png").getImage();
    private Image coin = new ImageIcon("coin.png").getImage();
    private int coinX = 700;
    private int coinY = GROUND - 50;

    public static void main(String[] args) {
        JFrame frame = new JFrame("Super Mario");
        frame.setSize(WIDTH, HEIGHT);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.setResizable(false);
        SuperMario game = new SuperMario();
        frame.add(game);
        frame.setVisible(true);
        new Thread(game).start();
    }

    public void paint(Graphics g) {
        g.drawImage(background, 0, 0, null);
        g.drawImage(mario, x, y, null);
        g.drawImage(coin, coinX, coinY, null);
        g.setColor(Color.WHITE);
        g.drawString("Press SPACE to jump", 50, 50);
    }

    public void keyPressed(KeyEvent e) {
        if (e.getKeyCode() == KeyEvent.VK_SPACE && !isJumping) {
            isJumping = true;
        }
    }

    public void keyReleased(KeyEvent e) {}

    public void keyTyped(KeyEvent e) {}

    public void run() {
        while (isRunning) {
            if (isJumping) {
                y -= SPEED;
                jumpCount++;
                if (jumpCount == jumpHeight) {
                    isJumping = false;
                    jumpCount = 0;
                }
            } else if (y < GROUND) {
                y += SPEED;
            }

            if (coinX < 0) {
                coinX = 800;
            }
            coinX -= SPEED;

            if (x + mario.getWidth(null) > coinX
                    && x < coinX + coin.getWidth(null)
                    && y + mario.getHeight(null) > coinY
                    && y < coinY + coin.getHeight(null)) {
                coinX = 800;
            }

            repaint();

            try {
                Thread.sleep(50);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

这个示例代码实现了以下功能：

- 通过键盘控制超级玛丽跳跃
- 超级玛丽会在跳跃时向上移动，并在达到一定高度后自动落下
- 超级玛丽会在落地时停止移动
- 超级玛丽会在接触到金币时收集金币

您可以根据自己的需要进行修改和扩展。
