In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

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

Hi all This has been my hobby project for quite a few years now It started as a small engine to serve as a sandbox to try out new 3d graphics ideas After adding many features through out the years and re-writing the entire engine a few times, this is the latest state It currently supports loading models with animations, textures, lights, shadow maps, normal maps, and some other goodies I've also recently added voxel raymarching as an alternative renderer, along with a fun physics simulation :)

Hello HN, Just wanted to show this little 2D game engine that I've been working on for some time (around 2 years on the editor part, longer on some of the components). It's quite full featured but obviously this a project of such magnitude already that the work never really ends. That being said it's definitely already at a point where games can made and published. The editor runs natively on Windows and Linux using Qt5. The games can run on both Win and Linux as well as on WASM with WebGL. Feature wise there's a bunch of the stuff you'd expect. Audio, graphics, scripting,…

Hello, Hacker News! My name is Lillian (see: http://about.lillian.link/), and I just released version 0.2 of my MIT-licensed game engine, Hypatia(http://lillian-lemmer.github.io/hypatia/). Hypatia is a game engine for single player 2D action adventure games. You can use it to make a game like Legend of Zelda: Oracle of Ages and Oracle of Seasons. Hypatia is aimed at non-programmers and programmers alike. I'm seeking any sort of feedback. Hypatia supports FreeBSD first, but has great support for just about any platform…
