Unity 3D游戏开发 - C#语法基础 | 数组之二维数组

二维数组基本语法

• 声明+初始化

  数据类型[,]  数组名 = new 数据类型[行数,列数];

• 赋值与取值
  • 赋值：   数组名[下标,下标] = 值;
  • 取值：   数组名[下标,下标];
• 声明+初始化+赋值

  数据类型[,]  数组名 = new 数据类型[,]{
  
     {0，0，0，0，0，0，0，0，0，0},
     {1，1，1，1，1，1，1，1，1，1}
  
  };                  //每一行对应一个大括号.

二维数组的遍历

• for循环嵌套

  数组名.GetLength(轴向下标);     //可以获得某个轴向的元素个数.
  
  
              int[,] intArray = new int[,]{
                  {1,2,3},
                  {11,22,33},
                  {111,222,333},
                  {1111,2222,3333}
              };
  
              for (int i = 0; i < intArray.GetLength(0); i++)
              {
                  for (int j = 0; j < intArray.GetLength(1); j++)
                  {
                      Console.Write(intArray[i, j] + "\t");
                  }
                  Console.WriteLine();
              }
  
              Console.ReadKey();

二维数组在游戏中的应用

• 存储游戏地图
• 练习：二维数组存储迷宫地图.

              int[,] gamesMap = new int[,]{
                  {1,1,0,1,1,1,1,0,1,1,1,1,1,1,1},
                  {1,0,0,0,0,0,1,0,0,0,0,0,1,1,1},
                  {1,1,0,0,0,0,0,0,1,0,0,0,0,1,1},
                  {1,1,0,0,0,0,1,0,0,0,0,0,0,1,1},
                  {1,1,1,0,0,1,0,0,0,0,0,0,0,0,1},
                  {1,0,0,0,0,1,0,0,1,0,1,1,1,1,1},
                  {1,0,0,0,0,0,1,0,0,0,0,0,1,1,1},
                  {1,1,1,1,1,1,1,1,1,1,1,0,1,1,1}
              };
  
              for (int i = 0; i < gamesMap.GetLength(0); i++)
              {
                  for(int j = 0; j < gamesMap.GetLength(1); j++)
                  {
                      if(gamesMap[i,j] == 1)
                      {
                          Console.Write("■");
                      }
                      if(gamesMap[i, j] == 0)
                      {
                          Console.Write("□");
                      }
                  }
                  Console.WriteLine();
              }
  
             Console.ReadKey();
