Quick question, but I was wondering why my villager breeder isn't working, and I may have found a reason. My villager breeder is <64-or-so blocks required away from my iron farm, but my iron farm is high in the sky, making it more than 64 blocks away. I know that euclidean distance is calculated for this stuff (What's the minimum distance between two iron golem farms?), but is that only for the X and Z coordinates? So my here's my question: "Is height calculated into making villages valid?"
