Java实现泡泡堂对战版游戏的示例代码
前言
《泡泡堂II》是一个基于java的自制游戏,使用了MVC模式
,分离了模型、视图和控制器,使得项目结构清晰易于扩展,使用配置文件来设置游戏基本配置,扩展地图人物道具等。同时,该程序编写期间用了单例模式、工厂模式、模板模式等设计模式。为了游戏的可玩性,特意设计了平滑碰撞以及机器人。
主要设计
- 设计游戏界面,用swing实现
- 绘制游戏启动界面、结束界面、地图、主角、道具
- 实现泡泡爆炸
- 为了尽量复原泡泡堂游戏,初步实现了机器人功能。该机器人可以判断障碍物释放炸弹、规避炸弹、攻击玩家。
- 实现道具掉落和相应属性加成
- 实现游戏音效和背景音乐
- 平滑碰撞:人物在拐角处移动的时候经常不是刚好对齐的状态,程序会判定玩家碰撞了障碍物所以导致玩家无法拐弯。所以我们在处理这种情况的时候,会让玩家进行平滑的移动使得玩家看上去是滑进去的,增强玩家游戏体验
- 设计单/双人模式

游戏启动类
public class GameStart { private static GameFrame gameFrame; //游戏启动入口 public static void main(String[] args) { // 资源加载 try { ElementLoader.getElementLoader().readGamePro(); ElementLoader.getElementLoader().readImagePro(); ElementLoader.getElementLoader().readCharactorsPro(); ElementLoader.getElementLoader().readBubblePro(); ElementLoader.getElementLoader().readSquarePro(); } catch (IOException e) { System.out.println("资源加载失败"); e.printStackTrace(); } //初始化 gameFrame = new GameFrame(); //界面显示 gameFrame.setVisible(true); //音乐播放 GameMusicPlayer musicPlayer = new GameMusicPlayer(); musicPlayer.start(); } /** * 界面切换 * @param panelName 界面名称 */ public static void changeJPanel(String panelName){ if(panelName == "game") { GameController.setGameRunning(true); gameFrame.addListener(); } else { GameController.setGameRunning(false); gameFrame.removeListener(); } gameFrame.changePanel(panelName); //强制刷新,否则监听无效 gameFrame.setVisible(false); gameFrame.setVisible(true); } public static void startNewGame() { GameController.setGameRunning(true); gameFrame.startGame(); changeJPanel("game"); } }
核心监听类

总结
通过此次的《泡泡堂对战版》实现,让我对JAVA的相关知识有了进一步的了解,对java这门语言也有了比以前更深刻的认识。
java的一些基本语法,比如数据类型、运算符、程序流程控制和数组等,理解更加透彻。java最核心的核心就是面向对象思想,对于这一个概念,终于悟到了一些。
