C#帶你玩掃雷（附源碼）

這篇文章主要介紹了C#帶你玩掃雷（附源碼），詳細的介紹實現(xiàn)掃雷的方法，具體一定的參考價值，有興趣的可以了解一下

掃雷游戲，大家都應該玩過吧！其實規(guī)則也很簡單，可是我們想自己實現(xiàn)一個掃雷，我們應該怎么做呢？

Step1: 知曉游戲原理

掃雷就是要把所有非地雷的格子揭開即勝利；踩到地雷格子就算失敗。游戲主區(qū)域由很多個方格組成。使用鼠標左鍵隨機點擊一個方格，方格即被打開并顯示出方格中的數(shù)字；方格中數(shù)字則表示其周圍的8個方格隱藏了幾顆雷；如果點開的格子為空白格，即其周圍有0顆雷，則其周圍格子自動打開；如果其周圍還有空白格，則會引發(fā)連鎖反應；在你認為有雷的格子上，點擊右鍵即可標記雷；如果一個已打開格子周圍所有的雷已經(jīng)正確標出，則可以在此格上同時點擊鼠標左右鍵以打開其周圍剩余的無雷格。

1代表1的上下左右及斜角合計有一顆雷，依次輪推，2則有2顆，3則有3顆..

在確實是炸彈的方格上點了旗子，就安全了，不是炸彈的被點了旗子，后面會被炸死的..問號就先不確定這里有沒有炸彈，不會存在點錯了被炸死的狀況..

Step2: 由step1可知，游戲由格子組成，翻譯成代碼語言就叫做數(shù)組，也就是游戲地圖就是一個二維數(shù)組。格子對象，格子的值即當前雷的數(shù)量，那么此時我們暫定雷的數(shù)字標識為-1。除此之外，格子對象還有是否被顯示，顯示當前雷數(shù)量等屬性，那么我們大概可以定義這樣一個類：

 public class CellBlockRole
  {
    /// <summary>
    /// 位于游戲地圖中的坐標點X
    /// </summary>
    public int X { get; set; }

    /// <summary>
    /// 位于游戲地圖中的坐標點Y
    /// </summary>
    public int Y { get; set; }

    /// <summary>
    /// 是否展示最后格子所代表的結(jié)果
    /// </summary>
    public bool IsShowResult { get; set; } = false;

    /// <summary>
    /// 是否計算數(shù)字結(jié)果
    /// </summary>
    public bool IsComputeResult { get; set; } = false;

    /// <summary>
    /// 是否已經(jīng)展示過計算結(jié)果了
    /// </summary>
    public bool IsHasShowComputed { get; set; } = false;

    /// <summary>
    /// 當前的格子的角色數(shù)字， -1：地雷，其他當前雷的數(shù)量
    /// </summary>
    public int Number { set; get; } = 0;

    /// <summary>
    /// 是否被Flag標識
    /// </summary>
    public bool IsFlag { get; set; } = false;

    /// <summary>
    /// 是否是雷
    /// </summary>
    public bool IsBoom => Number == -1;

  }

主要代碼已經(jīng)實現(xiàn)，現(xiàn)已知現(xiàn)有代碼的定時器由問題，暫時不支持Flag（旗子標識）。當然代碼中還有其他不足的地方，游戲持續(xù)優(yōu)化中。。。
