Inhyeong
Co-op Multiplayer RPG • 2024 — Present
About this Project
A co-op anime-styled 3rd-person RPG built for playing with a friend in a fantasy-dark world. Built with Unity and Fishnet Networking for multiplayer functionality, featuring real-time combat, exploration, and enemies that think for themselves, powered by the custom MIRAI AI.
MIRAI
Custom AIModular Intelligent Response & Adaptive Interaction
The custom enemy AI built for Inhyeong. Enemies perceive, remember, and decide for themselves, and everything they do comes from weighing their situation rather than following a script.
Server-Side Minds
All decisions happen on the server. Clients only see the results, so co-op stays consistent
Perception
Vision cones, line of sight, and memory. Enemies act on what they have actually seen
Soul Recollections
Fights leave impressions. Enemies remember players, and some hold grudges
Soul Personality
Personalities drift over time, so enemies of the same kind grow apart
Pack Behavior
Packs coordinate without a commander. The behavior emerges from individual minds
Built for Crowds
Designed for 50-100+ thinking NPCs at once while staying light on the frame
Cross-World Server
PoC CompleteAn opt-in system where solo players can be affected by other players across separate game sessions. Players can send custom quests, deliver monsters, and interact through a shared token economy — making single-player sessions feel connected to a living world.
Server-Authoritative
Flask API on Fly.io handles all rewards, costs, and validation
Token Economy
Spend tokens to create quests and send deliveries, earn by completing them
Mode-Agnostic
Same interfaces work in both singleplayer and multiplayer
Steam Auth Ready
Scaffolded for real Steam authentication with development fallback
