whar are you speaking about ?

 

im talking about the stupidity of making codes to prevent "possible" hacks.. when its logical to fix the problem at its source? it means that instead of making a check on enter world or whatever.. you fix the villagemasterinstance and prevent the skill hack in the first place.

 

anyway, i guess this code is usefull if you dont know how and you wanna make something custom..

      Outerlude - A Modern Interlude aCis fork

      By Nightw0lf · Posted

      Migrating a legacy Interlude server to PostgreSQL while adding real observability is basically forcing 2006 MMO engineering to attend a 2026 infrastructure conference at gunpoint. PS: which revision of aCis? PS: 🧻what was broken during this whatever you call it.    AAC Guard beign asked to adapt to this be like: - Creating bugs since early 2018

      Outerlude - A Modern Interlude aCis fork

      By Elfo · Posted

      I came out of my cave as I do once every 5 years. By now, I know nobody really cares about L2, but I still find it fun to experiment. Everything you see here will be free and open source. I have no interest in selling anything.   Long story short, I like to revisit Interlude and apply what I've learned to see how far I can push it. Here's Outerlude, a public fork of aCis for the modern age.   Video demo:   Work that has been done:   Redone the netcode from scratch to be async The NPC AI was completely redone based on Finite State Machines Moved to PostgreSQL and using some of its cool features Lots of config that should be hot reloadable has moved to the database OpenTelemetry instrumentation, where it makes sense, and a Grafana dashboard A built-in REST API for server management A built-in MCP Server for LLMs Nidrah AI, an AI Agent to make managing the server easier Real-time server map view Chat auditing and live snooping A new Fake Players Engine with a Node logic system and a new LLM planner for any behavior Just watch the video   If there is interest in this and I'm happy with it, or I get bored (which I always do), I will open-source it. Let me know what you think and if there is some feature you'd like me to implement.
