I don't know my version or loader



Add NPCs in Minecraft to create more alive and immersive encounters. Introduce behaviors and reactions: expanded animations, contextual decisions, and responses to world events.


Features
Dynamic Behaviors
- Daily Routines - NPCs follow simple schedules (work, leisure, sleep) and change their activities based on the time of day and weather.
- Contextual Reactions - NPCs react naturally to damage, fire, explosions, and environmental changes (water, lava, player proximity).
Enhanced Movement & Pathfinding
- Natural Movement - NPCs avoid obstacles with smoother movements and varied pacing instead of sudden turns.
- Block Interaction - NPCs seamlessly use doors, climb stairs, and stop in front of obvious dangers.
Social Interactions
- Conversations & Greetings - Experience small dialogues or gestures between NPCs and with the player.
- Grouping - NPCs can form groups or follow collective routines (such as gathering at markets or teamwork).
Customization & API
- In-Game Settings - Toggle features, control aggressiveness, behavior density, and detection ranges directly in-game.
