A comprehensive Minecraft plugin designed to empower server administrators with advanced control over Non-Player Characters (NPCs). Create, customize, and…
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Core Systems
Skin System
- Fetches player skins directly from Mojang's API using usernames.
- Extracts skin data (value and signature) and applies it to the NPC's appearance.
- Caches skin data locally in
skins.ymlto minimize API requests and improve performance. - All skin fetching operations are performed asynchronously to prevent server lag.
- Supports updating or clearing NPC skins via commands.
Persistence
- NPC Data: All NPC configurations (UUID, name, location, skin data, entity type, path points, equipment, behavior settings, interaction details) are stored persistently in
npcs.yml. - Skin Cache: Downloaded skin data is cached in
skins.yml. - Automatic Loading: All NPCs are automatically loaded and spawned when the plugin starts.
Command Handling
- A robust command system with clear subcommands for all NPC management tasks.
- Includes full tab completion for ease of use.
- Comprehensive error handling for invalid commands or missing selections.
Interaction Triggers
- Supports various methods for players to interact with NPCs: right-click, left-click, and proximity detection.
- When triggered, NPCs can display dialogue and execute server commands.
Pathfinding & Movement
- NPCs can be configured with patrol paths consisting of multiple waypoints.
- NPCs can be commanded to follow specific players.
Equipment Management
- A dedicated graphical user interface (GUI) allows server admins to visually equip NPCs with armor and items.
