坦克动荡java代码

坦克动荡是一款经典的Java游戏，代码实现相对简单，但需要考虑多个方面，如游戏窗口、坦克移动、子弹发射、碰撞检测等。以下是一个简单的坦克动荡Java代码示例：

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

public class TankGame extends JFrame implements KeyListener, ActionListener {

    private Tank tank;
    private Timer timer;

    public TankGame() {
        tank = new Tank(100, 100, 5, 5);
        timer = new Timer(50, this);
        timer.start();
        addKeyListener(this);
        setSize(800, 600);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setVisible(true);
    }

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

    @Override
    public void actionPerformed(ActionEvent e) {
        repaint();
    }

    @Override
    public void keyPressed(KeyEvent e) {
        tank.keyPressed(e);
    }

    @Override
    public void keyReleased(KeyEvent e) {
        tank.keyReleased(e);
    }

    @Override
    public void keyTyped(KeyEvent e) {
        // Not used
    }

    public static void main(String[] args) {
        new TankGame();
    }
}

class Tank {
    private int x, y, dx, dy;
    private int speed;

    public Tank(int x, int y, int dx, int dy) {
        this.x = x;
        this.y = y;
        this.dx = dx;
        this.dy = dy;
        speed = 5;
    }

    public void draw(Graphics g) {
        g.setColor(Color.GREEN);
        g.fillRect(x, y, 40, 40);
    }

    public void keyPressed(KeyEvent e) {
        int key = e.getKeyCode();
        if (key == KeyEvent.VK_LEFT) {
            dx = -speed;
        }
        if (key == KeyEvent.VK_RIGHT) {
            dx = speed;
        }
        if (key == KeyEvent.VK_UP) {
            dy = -speed;
        }
        if (key == KeyEvent.VK_DOWN) {
            dy = speed;
        }
    }

    public void keyReleased(KeyEvent e) {
        int key = e.getKeyCode();
        if (key == KeyEvent.VK_LEFT || key == KeyEvent.VK_RIGHT) {
            dx = 0;
        }
        if (key == KeyEvent.VK_UP || key == KeyEvent.VK_DOWN) {
            dy = 0;
        }
    }

    public void move() {
        x += dx;
        y += dy;
    }
}

这个示例代码实现了一个简单的坦克游戏，坦克可以通过键盘的上下左右键进行移动。代码结构如下：
1. `TankGame`类继承自`JFrame`，并实现了`KeyListener`和`ActionListener`接口，用于处理键盘事件和定时器事件。
2. `Tank`类表示坦克，包含位置、移动方向和速度等属性，并提供了绘制坦克和键盘事件处理的方法。
3. 在`main`方法中创建`TankGame`对象，启动游戏。
