java简易小游戏[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

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。

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\\\n游戏中有随机出现的苹果，碰到一个苹果加一分，\\\n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);
}
}
