在C＃中移动数组中的字符

Question

预期：char'H'在由默认“X”组成的5x5数组中移动。

结果1：网格在添加“H”和“P”时展开，而不是替换匹配的索引“X”。

结果2：char'H'不动。

到目前为止，这是代码：

class Mainclass
{
    public static void Main(string[] args)
    {

        Console.WriteLine("The Board Game");
        Console.WriteLine();
        Console.WriteLine(">>Press any key to begin<<");

        Console.ReadKey();
        Console.Clear();


        Console.WriteLine("The Board Game");
        Console.WriteLine();

        CreateGrid();

        Console.WriteLine();

        Console.WriteLine("H = your hero");
        Console.WriteLine();
        Console.WriteLine("X = floor tiles");
        Console.WriteLine();
        Console.WriteLine("P = enemy pawn");

        Console.WriteLine();
        Console.WriteLine();
        Console.WriteLine("Press the arrows in your keyboard to move in that direction");

    }

    public static void CreateGrid()
    {

        int width = 5;
        int height = 5;

        char[,] grid = new int[width, height];
        grid[2, 2] = 'H';
        grid[4, 4] = 'P';

        for (int x = 0; x < width; x++)
        {
            for (int y = 0; y < height; y++)
            {
                Console.Write(grid[x, y] + " ");
            }
            Console.WriteLine();

        }

        if (ConsoleKeydown(ConsoleKey.up)){
        get hero.index[,];
        newHeroPosition = Hero.index +1, +0;
        char hero.index = H;
        char newHeroPosition = x;
        }

        /*I want the tile to be identified and swap the char value
        of it with the one above it on the grid */


    }
}

}

Answer 1

这样的事情可以帮助你

public static void move(ref int[][] grid, ref int heroX, ref int heroY, int upDown, int leftRight) {
    if ((heroX + upDown >= 0) && (heroX + upDown < grid.Length) &&
        (heroY + leftRight >= 0) && (heroY + leftRight < grid[heroX + upDown].Length)) {
        int aux = grid[heroX][heroY];
        grid[heroX][heroY] = grid[heroX += upDown][heroY += leftRight];
        grid[heroX][heroY] = aux; //heroX and heroY were changed in the previous operation
    }
} 

只需传递网格，英雄的当前x，y位置，如果你想让他向下移动，则为+1，如果你想让他向上移动，则为向上移动，对于leftRight，也是如此。

好。代码很有趣。可能做得太多了。遗憾。
