基于JAVA实现的推箱子小游戏

Java推箱子小游戏实现：

推箱子小游戏曾经在我们的童年给我们带来了很多乐趣。推箱子这款游戏现在基本上没人玩了，甚至在新一代人的印象中都已毫无记忆了。。。但是，这款游戏可以在一定程度上锻炼自己的编程能力。

窗口画面设计：
import javax.swing.*;
import java.awt.event.*;

public class Pushbox extends JFrame implements ActionListener {
    private static final long serialVersionUID = -392323205976303799L;
    Game game;
    JLabel jl = new JLabel("推箱子游戏");
    JTextArea tips = new JTextArea("            游戏规则\n玩家通过上下左右按键\n移动小人推箱子到指定\n"
            + "的箱子归位处，当所有\n箱子都被推至归位处后\n则玩家成功通过该关卡");
    JButton jb1 = new JButton("选择关卡");
    JButton jb2 = new JButton("重新开始");
    JButton jb3 = new JButton("退出游戏");
    JLabel jlt = new JLabel("在下方输入关卡1-3");
    JTextField jt = new JTextField();

    Pushbox() {
        setTitle("推箱子");//设置窗口显示的名字
        setBounds(500, 200, 600, 470);//设置窗口相对于屏幕的显示位置(500，200)，窗口大小(600,470)
        setVisible(true);// 使窗口显示
        setLayout(null);// 清空布局管理器，之后的控件可自定义坐标位置
        jl.setBounds(265, 10, 100, 20);
        tips.setBounds(430, 40, 120, 120);
        jlt.setBounds(430, 180, 120, 20);
        jt.setBounds(430, 210, 120, 30);
        jb1.setBounds(430, 250, 120, 40);
        jb2.setBounds(430, 300, 120, 40);
        jb3.setBounds(430, 350, 120, 40);
        add(jl);
        add(tips);
        add(jlt);
        add(jt);
        add(jb1);
        add(jb2);
        add(jb3);
        jb1.addActionListener(this);
        jb2.addActionListener(this);
        jb3.addActionListener(this);
        game = new Game();
        add(game);
        game.Load(game.flag);
        game.requestFocus();
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == jb1) {
            String f = jt.getText();
            game.flag = Integer.parseInt(f) - 1;
            if (game.flag > 2 || game.flag < 0) {
                JOptionPane.showMessageDialog(this, "没有这一关！！！");//弹窗
                jt.setText("");
            } else {
                game.Load(game.flag);
                game.requestFocus();
                jt.setText("");
            }
        }
        if (e.getSource() == jb2) {
            game.Load(game.flag);
            game.requestFocus();
        }
        //如果点击了jb3按钮（退出游戏）
        if (e.getSource() == jb3) {
            System.exit(0);    //退出
        }
    }
}

地图读取及初始点设置：

public class Read {
    public int f, x, y;
    public int[][] map = new int[12][12];

    Read(int n) {
        f = n;
        for (int i = 0; i < 12; i++) {
            for (int j = 0; j < 12; j++) {
                map[i][j] = Pass.pass[f][i][j];
                if (map[i][j] == 5) {//找到人的位置
                    x = j;//把下标存起来
                    y = i;//把下标存起来
                }
            }
        }
    }

    int[][] getmap() {
        return map;
    }

    int getmx() {
        return x;
    }

    int getmy() {
        return y;
    }
}

游戏地图显示和控件操作：

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

public class Game extends JPanel implements KeyListener {
    int len = 30;//地图格子的长度
    Image[] img;//定义图像数组
    public int flag = 0;//定义关数,因为数组下表第一个是0,所以0代表第一关
    int mx, my;//定义任务初始位置下标
    int[][] newmap;//定义目前的地图数组(这个就是实时显示的，会根据移动改变)
    int[][] oldmap;//定义加载的地图数组(这个就是一开始的地图数据，不会改变)
    Read fnewmap;
    Read foldmap;

    Game() {
        setBounds(40, 40, 360, 360);
        setBackground(Color.white);
        addKeyListener(this);
        img = new Image[7];
        for (int i = 0; i < 7; i++) {
            //图片资源存放的相对路径
            img[i] = Toolkit.getDefaultToolkit().getImage(".\\pushing_boxes\\src\\main\\java\\com\\txz\\img\\" + i + ".png");
        }
        setVisible(true);
        Load(flag);
    }

    void Load(int i)//加载地图函数
    {
        fnewmap = new Read(i);//调用Read
        foldmap = new Read(i);//调用Read
        newmap = fnewmap.getmap();//获取地图数据给newmap数组
        mx = fnewmap.getmx();//获取初始人物的X位置
        my = fnewmap.getmy();//获取初始人物的Y位置
        oldmap = foldmap.getmap();//获取地图数据给oldmap数组
        repaint();//刷新界面并绘制地图
    }

    @Override
    public void paint(Graphics g)//绘制地图函数，(自带的库函数)，调用repaint()时就会调用这个函数，重写画界面
    {
        for (int i = 0; i < 12; i++) {
            for (int j = 0; j < 12; j++) {
                g.drawImage(img[newmap[j][i]], i * len, j * len, this);
            }
        }
