Version 2.2 - Inventory and states!
This versions (finally) adds support for NPC inventory and state handling. From now on you can set items in hand, armor and whether the NPC is on fire/crouching/invisible.
The methods you'll be looking for are NPC#setItem
and NPC#toggleState
.
KNOWN BUG: In 1.14 R1, there's an issue with NPCState#CROUCHING. This is something that's not functional yet.
Happy coding! 💻
