Hey, I'm planning on filling my city up with villagers. Tried to look on the Minecraftforum but couldn't find anywhere about the AI navigation. How do they know where to walk in the village? Do they just look for houses and navigate from door to door? Am I going to need to place a house (or at least a hut) every couple of blocks? If so what is the maximum distance between the two houses?
To put it shortly, what keeps them from wandering off and how do I keep them from doing so?
