Question

您好最近我已经获得了创建小游戏的任务，但是看到我遇到了问题。当我试图移动我的球员，他开始在一个固定的位置，他将向右移动一次，但似乎他仍然锁定在起始位置，并在输入数字后再次向右移动，同样的答案（坐标我有打印出来）是相同的，游戏板也是一样的。 https://gyazo.com/9f23419a3300232d3f3d9e1168202cf3

    public string player(int movement)
    {
        int playerX = map.GetLength(0)-3; //rows
        int playerY = map.GetLength(1)-25; //columns

        if (movement == 8)
        {
            playerX--;
            map[playerX, playerY] = "P";
            Console.WriteLine("The player is located at: " + playerX +","+ playerY);
        }
        else if (movement == 6)
        {
            playerY++;
            map[playerX, playerY] = "P";
            Console.WriteLine("The player is located at: " + playerX + "," + playerY);
        }
        else if (movement == 2)
        {
            playerX++;
            map[playerX, playerY] = "P";
            Console.WriteLine("The player is located at: " + playerX + "," + playerY);
        }
        else if (movement == 4)
        {
            playerY--;
            map[playerX, playerY] = "P";
            Console.WriteLine("The player is located at: " + playerX + "," + playerY);
        }  
        else
        {
            map[playerX,playerY] = "P";
        }
        return "";
    }

每次调用player方法时，位置都是相同的，因为您使用局部变量来存储位置。

我想你想要的是使用全局变量，并在游戏开始时设置位置。

将变量声明移到方法之外:(将它们放在类中但不在方法内部）

int playerX, playerY;

设置地图创建时的位置。

map = // Something
playerX = map.GetLength(0)-3; //rows
playerY = map.GetLength(1)-25; //columns

如何将坐标[x，y]从2D数组移动到右边？ C＃
