太难找了………………！本来想自力更生，结果找了老半天都找不到，还是用了楼主的代码，非常感谢！

哇，终于找到方法了，谢谢楼主😚

总结一下：
1.打开Grid以后，"Y"字型交点上的地块为最小地块；
2.只有遇见最小地块以后浮空岛的边线才能转弯或者收束，否则只能一条线往前走；
3.“只要找到一群能连接成闭合网络的小节点”就能建造浮空岛，也就是说，如果最小节点之间无法闭合，或者要拐弯以后才能闭合的，则无法建造浮空岛
仔细分析了下发现是支撑柱的生成逻辑导致的，“Y”字型交点上的地块生成3个支撑柱，“十”字型交点生成4个，“*”字型交点生成5个，以此类推。只有当转弯处的地块为“Y”字型地块时，才不会生成支撑柱，否则至少生成1个支撑柱。当满足“闭合边线内不存在任何支撑柱”后，才会生成螺旋桨助推器，浮空岛建造成功。
所以实际上....浮空岛也不是随便造的，而且大小并不受自己控制，如果有幸能使最小节点闭合，浮空岛就能够成功；但如果最小节点和边线之间只差哪怕一格，浮空岛就无法成型，只能继续扩张...或者放弃

还可以这样！！！我要改造我的城市了 我一直以为无法完全悬空

形状不规律好像也能变成空岛，比如我这个形状乱七八糟但就是能飞
