布尔二维数组C＃使多个值为真

Question

您好我刚刚完成了一个网格代码。这些说明允许您向右，向左，向上或向下移动并输入特定值来移动。然而现在的问题是，输入的值是唯一变为真的位置。我试图让全部金额成为现实。例如，我们向右移动3，它应该是3个点=真而不是最后一个。任何人都可以帮助我吗？

为了回答你的问题，你没有看到每一个动作都是安全的原因是因为你没有检查每个位置，你只是将检查位置设置到你想要移动的位置而不是每个增量位置。我在这个答案中添加了一个更多逻辑的类，因为游戏中的每个动作都需要稍微不同的逻辑才能工作。

public class DrillGame

    private const int Columns = 401;

        _currentGameRow = -1;

            string direction = Console.ReadLine();

            Console.WriteLine("What value would you like to move by?");
            string distanceInput = Console.ReadLine();
            int distanceToMove = Convert.ToInt32(distanceInput);

            // Use if statements
