Im making a plugin, and it includes one mob ID. I need a librarian villager ID, or something I can do to make a villager a librarian. I searched Google... Nothing. Many thanks, TheDeibo
villager's network_id=15 librarian's $namedtag->Profession=1 profession is in NBT, so I think there is no id.
It is an ID. Just that it isn't a unique entity ID, just like a dropped diamond has the same ID as a dropped dirt.
