我想创建一个名为Quoridor的游戏，其中一个Pawn必须到达另一侧的董事会的Java类的方法。 Pawn类（一个坐标）穿过9x9二维阵列，而Wall类（2个坐标）放置在10x10二维阵列上。墙壁基本上放置在典当广场之间。典当不能穿过墙壁或其他典当，我不知道如何用两个二维阵列实现BFS。我是编程新手，想知道是否有人可以一步一步地告诉我如何创建这样的方法。目前有一个Pawn和Wall类有必要的get和set方法。 enter code here多维二维数组广度优先搜索Java

到目前为止，您是否有任何代码？ – Joris
我刚刚添加了我们的主类，在那里我们有我们正在使用的shortestPath（）方法。不知道如何解决它 –
