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); }}
