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,…

    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!

    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! Just for fun, I built an interactive Hacker News Simulator. You can submit text posts and links, just like the real HN. But on HN Simulator, all of the comments are generated by LLMs + generate instantly. The best way to use it (IMHO) is to submit a text post or a curl-able URL here: https://news.ysimulator.run/submit. You don't need an account to post. When you do that, various prompts will be built from a library of commenter archetypes, moods, and shapes. The AI commenters will actually respond to your text post and/or submitted link. I really wanted it to feel…

    Hi everyone! I'm one of the developers behind this project. I wrote it with my two brothers, Daniel and Ricardo. For years the three of us have been curious about how multiplayer games work, which is why we decided to work on this project. Our goal was to gain a deep understanding of how different players can share the same 3D space, which is why we wrote our own tiny game engine instead of using something like Unity. We wrote the engine using C++ and OpenGL, and we then compiled it to WebAssembly using Emscripten so that it would run effortlessly on web browsers. We are really excited about…

    Hey folks — here’s a small experiment I hacked together over the weekend: https://cleoselene.com/ In short, it’s a way to build multiplayer games with no client-side game logic. Everything is rendered on the server, and the game itself is written as simple Lua scripts. I built this to explore a few gamedev ideas I’ve been thinking about while working on Abstra: - Writing multiplayer games as if they were single-player (no client/server complexity) - Streaming game primitives instead of pixels, which should be much lighter - Server-side rendering makes cheating basically…

    Hi HN, blockchain3d.info (http://blockchain3d.info) is a free 3D and VR Bitcoin Blockchain browser available for Windows, Android (with Google Cardboard for Virtual Reality), Linux and MacOS. The tool lets you enter a starting address or transaction, then navigate the Bitcoin network as far as you like (or as your hardware will allow, performance wise) to see inflows and outflows, all in 3D (or VR with Cardboard). Would love to hear feedback from HN folks!

    I think it's finally time to lock version 0.2 of my 4d side project. (Since previous Show HN a couple of years ago: https://news.ycombinator.com/item?id=37100760 I scrapped lots of stuff and concentrated on making a javascript "game engine") The sole purpose of this project is to explore whether it's possible to make the human brain spatially aware of four dimensions using Virtual Reality. It’s my first ever game project, my first time using Unity, first time writing C#, and my first anything with WebXR, so please be gentle! To manage expectations, it isn't visually pleasing…

    Most games have limits. You can only use preset features, need coding for customization & adding mods, require expensive extra devices. We wanted to remove those barriers. That’s why we are building space zero—a browser based 3D world powered by AI. We plan to build players can freely mix items to generate unexpected creations with unique properties and sounds. Also the world itself is dynamically generated, evolving endlessly. I uploaded a demo version I’ve been working on for the past month! I hope to get any feedbacks or comments :)

    We did a "Show HN post" 6 months back of our startup and we're very excited to show everyone how far we've come as well as the lessons we've learnt so far! It's been a roller-coaster so far and we think there's lot more of the same to come! We did apply for Ycombinator funding but got turned down :( But may re-apply soon :) For those that don't know, our startup is called Scirra and we make Construct 2 which is an HTML5 game engine (http://www.scirra.com). Our engine allows anyone to make HTML5 games without knowing any programming. It's only me and my brother working on this and we're based…

    For the past few months, I’ve been hacking together Hive: a retro-style virtual workspace for devs who love building in public. It’s a bit rough but already has some cool features: - AI-powered presence to represent you when you’re offline. - Live video streaming to showcase your work in real time. - VS Code integration to broadcast your status live. - GraphQL API for full customization and hackability (such as using your own agents) - Web3 donations to support and get support from other builders. In this demo, you can claim a desk by walking up to it and pressing E, then personalize it with…

    Hi Hacker News. Today, we're excited to launch Aircada, a lightweight browser based 3D design studio for creating interactive 3D content on the web. We remember using three.js back in 2010 before we had smart phones. And now 15 years later it feels like 3D on the web is finally starting to see the light of day. We use the beloved three.js under the hood - with WebGPU alongside the awesome node material system and TSL shader language. 1 minute demo video showing off what Aircada can do: https://youtu.be/hAJPnP93pfA Hop right into a template:…

    Hey all, I'm a product designer and I built this cause' when I was designing liquidity pool and staking features for this DAO, I didn't know how the user flow worked and how the UI looked for similar pages, so I was constantly switching back and forth Balancer, Uniswap, and OlympusDAO as references. I thought that I might not be the only one with this problem, so I built this library of userflow screenshots, and annotated them, to share with the web3 community of builders, designers, and developers. Would love feedback if you're a builder in web3, let's connect too! (Also I'm aware that…
