Saving a Mob's Location

So I'm coding this plugin where you type in a command and it spawns a villager. (Have that working)
How would I save that villager so when you reload or stop and start the server, it will still be there?

 

I'm pretty experienced with entities, buut im not at home and i dont have IDE now. I guess you could do:

Entity e = Entity.VILLAGER;

Spawn e and after that you can get it's location.

 

Reloading the plugins is basically the same as stopping and starting your server - nothing you create dynamically is REALLY saved unless you store it somewhere external other than within the plugin itself - for example, a saves.yml file.

You should look into the Configuration API Reference to see how you can store information in a yml file.

An alternative is to store the location in a database (x,y,z) such as MySQL or MongoDB. This is a little more complex, however.

 

Villagers stay alive once the server is stopped and restarted. Only hostile mobs (and maybe water mobs) are deleted upon reload. To spawn the mob do :

world.spawnEntity(Location, EntityType.Villager);

Now if your villager is getting removed on reload, save the villagers location to a txt file which is written onDisable(). Then in OnEnable write a txt file reader which then interprets your txt file's locations. If you need help with this ask.
