Until now the villagers wandering randomly around the village.
What about adding a special block to work as path.(road)
Then define the villager's AI to have a BIG% to choose moving on thoese blocks.
The resutlt will be to have villager that actually move trhough villager roads, meet each other, and having a more... realistic village behaviour

Currently they're just using Mojang's AI. I plan to use my own in a later update.
