我的小项目
我想用少于500行的代码重新创建Ketchapp的

我的问题 当我在不删除轨迹的情况下播放它时（访问时按钮保持橙色），它的ALMOST效果很好，您可以通过取消注释第41行来进行测试。但是在删除轨迹时（就像原始的圆点一样），这非常令人困惑。我试图在多个小时内找到问题，这就是为什么我在这里发布所有内容的原因：/
当我一开始单击按钮（2,3）时，它停止工作-找不到边界，但是我只阻止了一个按钮...将它与findDirection方法进行比较时，我没有任何意义，其中包括广度优先搜索算法。其他按钮也一样。 取消注释第135行时会稍微好一点，这会增加游戏的随机性。
如果有人可以帮助我或加入该项目，那就太棒了。它只是出于娱乐目的，我想学习新事物。
