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

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。

以上就是Java实现泡泡堂对战版游戏的示例代码的详细内容，更多关于Java泡泡堂的资料请关注我们其它相关文章！
