I’m playing unmodded Minecraft on the xbox 360, in survival mode. I have explored the entire map, and found 1 village. The last villager died. What can I do to get villagers back?
My memory has faded a lot since 1.7 (PC) but I recall you being able to throw a splash potion of weakness at a zombie villager then use a golden apple (Not enchanted golden apple) on the zombie straight afterwards and give it 2-5 mins to be converted to a villager.
Be sure to keep it away from other zombies for obvious reasons.
More info and evidence can be found here
It increase the village population, you must make village houses. A simple way to make a village house is a door and a block next to it. The systems trys to detect if it's a house or not. If the system detects it as a house, then a villager appears. You can make a lot of houses and you can make the population grow. You need to have 2 houses in order for villagers to breed.
Example of a house needed to increase population:
Video example of making a population:
Update: Since you have no villagers, try to find a zombie villager and cure it by:
Throwing a Splash Potion of Weakness
Feed it a Golden Apple.
Wait until it turns into a normal villager.
Try to push it al the way to where your village spawner is you know the village houses in the picture at the top.
You will need 2 villagers to start breeding, so repeat the steps above and you should have an infinite amount of villagers.
