Lyceum – An MMO game built with Zig and Erlang
Hey HN, this is a small project myself and closer friends have been building on our free time (https://github.com/Dr-Nekoma/lyceum), it finally reached 0.1.0, we are open to feedback! The original idea was to experiment with Zig + Raylib, eventually we wrote a small server in Erlang as well. We started by first interacting with Erlang via its C bindings, but this eventually led to some of us to prototyping our own tooling to better integrate Zig types with Erlang, we called such tool "zerl" as its avaliable here…
In plain words
Lyceum is a multiplayer online game built using Zig for the client with Raylib graphics and Erlang for the server backend. The project includes zerl, a tool for integrating Zig types with Erlang, addressing challenges in the two-language integration. Developed as a collaborative hobby project by a group of programmers, it uses Nix for development infrastructure and has reached version 0.1.0. The codebase is available on GitHub.

Most of the developers are NixOS users, so the tooling heavily relies on Nix as well, including a Postgres running our devshell as well.

Hello HN! We’re a small creative studio specializing in real-time 3D experiences. Netlify approached us to design and build an interactive experience to celebrate reaching 5 million developers. Inspired by the classic game Marble Madness, we created a gamified experience where users control a ball through playful, interactive levels. The goal was to blend marketing content with the look and feel of a game to engage users. The app is built with Three.js [1], using our custom render pipeline and shaders, and uses Rapier for physics simulation [2]. The 2D content is overlaid on the WebGL view…
- IBI built an indie, browser-based MMORPG2024 · alpha.reconquer.online · ▲340
I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…

- IWI wrapped the Zorks with an LLMJan 2026 · infocom.tambo.co · ▲111
I grew up on the Infocom games and when microsoft actually open-sourced Zork 1/2/3 I really wanted to figure out how to use LLMs to let you type whatever you want, I always found the amount language that the games "understood" to be so limiting - even if it was pretty state of the art at the time. So I figured out how to wrap it with Tambo.. (and run the game engine in the browser) basically whatever you type gets "translated" into zork-speak and passed to the game - and then the LLM takes the game's output and optionally adds flavor. (the little ">_" button at the top exposes the…
- ISI spent 6 years making a cool free game2015 · ▲151
Hey everyone! Long time lurker, first time poster. I've just reached beta in my game BoxByte Lyte. -What is it- It's a free 3d arcade game for hardcore players that uses color matching in interesting ways. Also it's a one button game, well movement and one button. Cool huh? The final release will be free too. -What I need- This is a very challenging game, so I really need to balance the difficulty so that it's still hard but not impossible. It would be great just to hear your experiences of the game and how far in it you got. -Where can I report bugs?-…
- AOAn online 2D MMO game, written in Rust and JavaScript2024 · polyfight.io · ▲171
I made a game (https://polyfight.io/) which revolves around a player (a tank) leveling up and upgrading by killing shapes and other tanks (partially inspired by https://diep.io). It has a bunch of features, a vast number of tanks, an inbuilt chatting system, clans to make teams with your friends, a colour scheme maker, controllable sandboxes which can be public or private, a last man standing gamemode, and an inbuilt 1v1 system with its own ELO rankings and a global leaderboard. The game has a few players right now, and I'd hope to spread the joy players have with…

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
