If I build a city in Minecraft and then make Villager in the city, what happens? Have the permanent residences or how is that?
No, they do not destroy anything, just run around and through simple doors.
Exactly he's right… I know that even though I only played minecraft for 4 weeks and that years ago… Shame on you xD
No, villagers have no permanent residence. They just randomly walk around, and when night falls, they move back to the nearest house. Otherwise, they will not do much but walk randomly through the area.
If you have more than 21 wooden doors in town, iron golems will spawn.
