C#實現2048小遊戲
阿新 • • 發佈：2019-02-11
要實現這個簡單的小遊戲主要在於實現一個方向移動
數字的移動及合併該如何處理
然後其它方向的邏輯是相同的
我做的這個基本功能實現了
主要分為三個類
Box.cs格子類（一些格子裡儲存的資料，行下標，列下標，是否合併過的開關。。）
Grid.cs網格類（主要演算法在裡面）
Manage2048.cs控制遊戲類（控制遊戲流程）
程式碼供參考
Box.cs格子類
/// <summary> /// 格子類 /// </summary> class Box { //行下標 private int rowIndex; //列下標 private int colsIndex; public int RowIndex { get { return rowIndex; } set { rowIndex = value; } } //是否第一次合併 public bool isMerge = false; public int ColsIndex { get { return colsIndex; } set { colsIndex = value; } } //格子上的數字 public int Number { get; set; } public Box(int row, int cols) { this.RowIndex = row; this.ColsIndex = cols; Number = 0; } }
Grid.cs網格類
/// <summary> /// 網格類 /// </summary> class Grid { int row = 0;//行 int clos = 0;//列 Box[,] boxes; bool isEnableRandom = false;//是否還會產生隨機數（預設不能） int gridNum = 2;//格子上的隨機數 bool isFirst = true; //是否是第一個 Queue<Box> boxisMerge;//佇列儲存合併過的數 Random ran;
