C#带你玩扫雷(附源码)
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?
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 class CellBlockRole { /// <summary> /// 位于游戏地图中的坐标点X /// </summary> public int X { get; set; } /// <summary> /// 位于游戏地图中的坐标点Y /// </summary> public int Y { get; set; } /// <summary> /// 是否展示最后格子所代表的结果 /// </summary> public bool IsShowResult { get; set; } = false; /// <summary> /// 是否计算数字结果 /// </summary> public bool IsComputeResult { get; set; } = false; /// <summary> /// 是否已经展示过计算结果了 /// </summary> 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。。。
