C#带你玩扫雷(附源码)

时间:2022-01-24 13:45     来源/作者:Cosecant

扫雷游戏,大家都应该玩过吧!其实规则也很简单,可是我们想自己实现一个扫雷,我们应该怎么做呢?

C#带你玩扫雷(附源码)

step1: 知晓游戏原理

扫雷就是要把所有非地雷的格子揭开即胜利;踩到地雷格子就算失败。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;如果点开的格子为空白格,即其周围有0颗雷,则其周围格子自动打开;如果其周围还有空白格,则会引发连锁反应;在你认为有雷的格子上,点击右键即可标记雷;如果一个已打开格子周围所有的雷已经正确标出,则可以在此格上同时点击鼠标左右键以打开其周围剩余的无雷格。

1代表1的上下左右及斜角合计有一颗雷,依次轮推,2则有2颗,3则有3颗..

在确实是炸弹的方格上点了旗子,就安全了,不是炸弹的被点了旗子,后面会被炸死的..问号就先不确定这里有没有炸弹,不会存在点错了被炸死的状况..

step2: 由step1可知,游戏由格子组成,翻译成代码语言就叫做数组,也就是游戏地图就是一个二维数组。格子对象,格子的值即当前雷的数量,那么此时我们暂定雷的数字标识为-1。除此之外,格子对象还有是否被显示,显示当前雷数量等属性,那么我们大概可以定义这样一个类:

   public bool ishasshowcomputed { get; set; } = false;
 
   /// <summary>
   /// 当前的格子的角色数字, -1:地雷,其他当前雷的数量
   /// </summary>
   public int number { set; get; } = 0;
 
   /// <summary>
   /// 是否被flag标识
   /// </summary>
   public bool isflag { get; set; } = false;
 
   /// <summary>
   /// 是否是雷
   /// </summary>
   public bool isboom => number == -1;
 
 }

主要代码已经实现,现已知现有代码的定时器由问题,暂时不支持flag(旗子标识)。当然代码中还有其他不足的地方,游戏持续优化中。。。
