我正在尝试构建一个由瓷砖组成的随机城市，到目前为止，我可以构建一个阵列，设置城市边缘，放置一个随机建筑物，例如教堂或工厂，并且可以在设置区域内放置随机旋转的瓷砖。
但是我需要某种算法或例程，通过选择正确的瓷砖并以正确的方式旋转它，从而创建一个相互连接的街道迷宫，以免最终出现无法以某种方式到达的区域。
我拥有的瓷砖是 - 特色瓷砖（如教堂或工厂） 直路 t-junction 十字路口 拐角 左拐角 右广场/环形交叉路口/庭院
我发现了大量基于地牢的示例，但没有任何类似使用固定瓷砖和在设定区域内匹配/旋转的例子，比如 10 瓷砖 x 10 瓷砖。
任何脚本提示将不胜感激，因为我正在兜圈子，使极其复杂的循环函数仍然无法工作
到目前为止我所拥有的代码 -
