Java编程是现代软件开发中一门非常重要的语言,尤其在游戏开发领域中更是广泛应用。为了让学习者更好地理解Java编程,下面将介绍一个简单的小游戏,并附上代码例子。

游戏名称:打地鼠游戏

游戏规则:

游戏共有9个洞口,随机出现地鼠并在洞口上弹出,玩家需要用锤子打击地鼠使其消失。每次出现的地鼠只会停留一秒钟,如果玩家没及时打击地鼠或者打到洞口,玩家生命值减一,生命值为0时游戏结束。

代码例子如下:


import java.awt.*;

import java.awt.event.*;

import java.util.Random;

import javax.swing.*;

public class HitMouse extends JFrame implements ActionListener {

  private static final long serialVersionUID = 1L;

  private static final int ROW = 3;

  private static final int COL = 3;

  private static final int HOLE_TOTAL = ROW * COL;

  private JLabel[] holes = new JLabel[HOLE_TOTAL];

  private JLabel scoreLabel;

  private JLabel lifeLabel;

  private Timer timer;

  private int score = 0;

  private int life = 3;

  private Random random = new Random();

  private HitMouse() {

    super("打地鼠");

    setSize(500, 400);

    setLocationRelativeTo(null);

    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    setLayout(new BorderLayout());

    JPanel panel = new JPanel();

    panel.setLayout(new GridLayout(ROW, COL));

    for (int i = 0; i < HOLE_TOTAL; i++) {

      JLabel hole = new JLabel();

      hole.setBorder(BorderFactory.createLineBorder(Color.gray, 2));

      hole.addMouseListener(new MouseAdapter() {

        @Override

        public void mouseClicked(MouseEvent e) {

          JLabel hole = (JLabel) e.getSource();

          if ("1".equals(hole.getName())) {

            hole.setIcon(null);

            hole.setName("0");

            score++;

            scoreLabel.setText("得分:" + score);

          } else {

            life--;

            lifeLabel.setText("剩余生命值:" + life);

            if (life == 0) {

              JOptionPane.showMessageDialog(null, "游戏结束");

              timer.stop();

            }

          }

        }

      });

      holes[i] = hole;

      panel.add(hole);

    }

    add(panel, BorderLayout.CENTER);

    JPanel panel2 = new JPanel();

    scoreLabel = new JLabel("得分:" + score);

    panel2.add(scoreLabel);

    lifeLabel = new JLabel("剩余生命值:" + life);

    panel2.add(lifeLabel);

    add(panel2, BorderLayout.SOUTH);

    timer = new Timer(1000, this);

  }

  private void showMouse() {

    int index = random.nextInt(HOLE_TOTAL);

    JLabel hole = holes[index];

    if ("0".equals(hole.getName())) {

      hole.setIcon(new ImageIcon(getClass().getResource("mouse.png")));

      hole.setName("1");

    } else {

      showMouse();

    }

  }

  @Override

  public void actionPerformed(ActionEvent e) {

    showMouse();

  }

  public static void main(String[] args) {

    HitMouse hitMouse = new HitMouse();

    hitMouse.setVisible(true);

    hitMouse.timer.start();

  }

}

通过本篇文章的小游戏例子,我们可以更好地理解Java编程语言的基础知识和代码实现,同时也可以通过自己编写的代码掌握如何用Java来进行游戏开发。
