JAVA实现经典扫雷游戏的示例代码
前言
windows自带的游戏《扫雷》是陪伴了无数人的经典游戏,本程序参考《扫雷》的规则进行了简化,用java语言实现,采用了swing技术进行了界面化处理,设计思路用了面向对象思想。
主要需求
1、要有难度等级,初级,中级,高级
2、由玩家逐个翻开方块,以找出所有地雷为最终游戏目标。如果玩家翻开的方块有地雷,则游戏结束
3、游戏主区域由很多个方格组成。使用鼠标左键随机点击一个方格,方格即被打开并显示出方格中的数字;方格中数字则表示其周围的8个方格隐藏了几颗雷。
4、用户右键可标记雷的位置
5、雷都被标记出来则胜利
主要设计
1、格子格数固定为10*10格
2、难度等级,初级:12,中级:24,高级:36
3、点击格子时,产生没有引爆的地图效果;
4、点击格子时,此格子是雷,则显示所有雷的位置,并递归清空非雷格子,结束游戏
5、实现检查所有的雷是否都被标记出来了,如果是,则胜利算法。
6、实现计时器算法,用来计时显示游戏开始多少秒
7、实现难度等级,雷数的显示
8、实现鼠标左键的实现逻辑
9、实现鼠标右键的标记逻辑

总结
通过此次的《扫雷》游戏实现,让我对swing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。
