I want to create a very large village in 1.14. I have read the Wiki quite a bit, and know that I need beds and "homes" to produce more villagers, and new beds can be joined to the village. My question is how close do the beds need to be to be considered a part of the village? Would this need to be inside the village boundary? and does the village boundary and center adjust based on every additional home? I included a picture to demonstrate my point. The red orange and yellow beds would be considered a village (assuming other requirements are met). Assuming a distance of 50 blocks, could the blue bed be considered a valid addition to the village?
Also, is there any way to easily identify the boundary and center of a village, perhaps similar to how hit-boxes can be toggled on and off, or some other trick?
