24 alternatives to A rudimentary game engine to build four dimensional VR evironments

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…

A JavaScript-based game engine for creating four-dimensional virtual reality environments. Built in Unity with WebXR support, it allows users to define 4D objects and behaviors while exploring them in VR to develop… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    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…

    I sometimes pick up random projects just because I can, this was one of those times. I made it as a week long project a while back this year but never shared here, so thought to go for it haha. I created a game inspired by Doom and the backrooms called The Backdooms under 2.4kb in minified html. (for reference, this entire post would be around 1.8kB haha) I had to use a not popular way of using GZip with Zlib headers (had to write my own script for compressing it, also in the repo) to eventually convert it a size 40 QR code that works right in your browser using Decompressionstream API. This…

    Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

    I was looking for a tiny library to easily transform both 2D & 3D objects with simple mouse / touch controls and a fixed camera, in the browser. Like a simple 3D editor but without requiring the user to be a Blender expert. Couldn't find anything lightweight, so I’m building one. Think Fabric.js but for 3D. Built entirely with Three.js / R3F. Borrowed some inspiration from VR/AR interaction systems for controls. Feel free to play with it and let me know what you think!

    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…

    I've spent 30 years making games as both a hobby and profession, working with Unity, Unreal, GameMaker, RPG Maker, Ren'Py, Godot, and many others. A few years ago, I attended a game dev meetup and met dozens of people with incredible passion for making games – but they were struggling because they lacked technical knowledge. That's when I decided to build a tool that anyone could use to create games. I started developing this as a side project, eventually raised ~$100K through crowdfunding in Korea, then secured ~$200K in angel investment. I assembled a team, and we've been building this…
