 《论语》有云：知之者不如好之者，好之者不如乐之者。学习知识，乐在其中，可以激发我们的学习效率。本文将带领各位小伙伴用 Java 来制作一个简单的小游戏，来加强对Java语言的理解。

java简易小游戏制作

游戏思路：设置人物移动，游戏规则，积分系统，随机移动的怪物，游戏胜负判定，定时器。

    }
    @Override
    public void keyTyped(KeyEvent e) {
    }
    @Override

游戏规则（使用弹窗）部分

package 代码部分;

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

public class TestGameRule extends JDialog {
    private int num = 1;
    public TestGameRule() {
        TextArea textArea = new TextArea(20,10);
        textArea.setText("游戏中有五个怪物随机移动，碰到怪物算死亡\
游戏中有随机出现的苹果，碰到一个苹果加一分，\
先达到十五分或者对手死亡算游戏胜利！");
        JScrollPane jScrollPane = new JScrollPane(textArea);
        this.add(jScrollPane);
        this.setBounds(200,200,400,400);
        this.setVisible(true);
        textArea.setEditable(false);
        setResizable(false);
        textArea.setBackground(Color.PINK);
    }
}

图片素材

package 代码部分;

import javax.swing.*;
import java.net.URL;

public class TestGameData {
    public static URL headerurl = TestGameData.class.getResource("/图片素材/header.jpg");
    public static URL p1player1url = TestGameData.class.getResource("/图片素材/1.jpg");
    public static URL p2player2url = TestGameData.class.getResource("/图片素材/2.jpg");
    public static URL appleurl = TestGameData.class.getResource("/图片素材/apple.jpg");
    public static URL monsterurl = TestGameData.class.getResource("/图片素材/monster.jpg");

    public static ImageIcon p1player1 = new ImageIcon(p1player1url);
    public static ImageIcon p2player1 = new ImageIcon(p2player2url);
    public static ImageIcon header = new ImageIcon(headerurl);
    public static ImageIcon apple = new ImageIcon(appleurl);
    public static ImageIcon monster = new ImageIcon(monsterurl);
}

主函数

package 代码部分;

import javax.swing.*;

public class TestStartGame {
    public static void main(String[] args) {
        //制作窗口
        JFrame jFrame = new JFrame("2D对战小游戏");
        jFrame.setBounds(10,10,790,660);
        jFrame.setResizable(false);
        jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        //添加游戏面板
        jFrame.add(new TestGamePanel());
        //设置可见
        jFrame.setVisible(true);
    }
}
