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…

Hey HN, We’re Philip, Amby, and Declan, and we made “multiplayer virtual computers” that you can embed anywhere, including 3D spaces. We decided to build this because we noticed that embedding third-party apps and websites can be a nightmare due to incompatible platforms, security issues, and poor UX. Adding multiplayer functionality to these embeds makes this problem exponentially more difficult. On the backend, we’re spinning up a VM and running a resource-optimized fork of Chromium which we then stream to participants via WebRTC. Since we’re hosting the servers running the applications,…

So just for fun, I wrote a complete multiplayer game in pure C++. I even wrote my own texture atlas packer, which is now used by Assassin's Creed, 2 scientific publications as well as a drone manufacturing company - each of these basically mentions the name of my game. There is even a claim that Unity patented some of the ECS ideas that originate from this project. See https://github.com/TeamHypersomnia/Hypersomnia#tech-highligh... for details. By the way the game is pretty darn good. 10 people connected yesterday to test a new map:…

Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc). Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I…

Colin here, creator of Nub. I’ve had the general shape of this in mind for years. Nub runs your code with stock `node`, augmented with a `--require` preload hook[0] that adds a transpiler (oxc-powered, packaged as a Node-API add-on), registers a module resolution hook[1], and injects polyfills as needed for APIs like `Worker`, `Temporal`, etc. All purely additive, your code ultimately runs using Node’s actual engine & stdlib implementations.

With all the turmoil in the game engine world recently, I thought I'd quickly post to show progress on our game platform dotbigbang.com. It's a fully integrated game platform where the multiplayer game editor and games all run on the web. You can make multiplayer games and share them with just a link with no setup at all. Breakdown of major features here: https://twitter.com/bobbydigitales/status/152647067103481856... We have comprehensive docs at http://docs.dotbigbang.com and a cosy Discord server at https://dotbigbang.com/discord All…

I'm making a platform for simple open source games you can play anywhere. Games are all just JavaScript classes and you can read the source of every game on the platform. I started working on initial "games" (mostly rendering tests) in 2018 and eventually built all of the platform stuff around it to make it easy to share games. There's also an in-browser editor available for you to make and publish games all from the browser. Would love some feedback on the games and studio features as well as the platform overall. All of the code is available at https://github.com/homegamesio

Hi, HN. Gui, Lucis, and the deco.cx team here — we're a bunch of Brazilians building an open-source, all-in-one web editor for the modern TypeScript dev. Check out our GitHub at https://github.com/deco-cx/deco and discover more at our site https://deco.cx/. We built frontend tools at a hyper-growth e-commerce platform for 9 years. Deco.cx is the thing that we wish existed when we were managing hundreds of enterprise-grade React-based websites. The gist is: JSX, HTMX, TypeScript, Tailwind and Deno. All visually editable in a beautiful, collaborative,…
