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

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…

Hello everyone, I would like to see if there is any interest in this little project that I have been working on for the past few years. Could be relevant, seeing the direction in which the mainstream game engines are going. I didn't really like any of the already existing options, so I tried to make my own and it turned out to be easier than expected. It's sort of like a low-budget Unreal/Source, but with open-world streaming support and it is free and open source. Very old-school. But optimized for more modern hardware. Very fast too. Still not production ready, but it seems like it is…

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…

GitHub repo: https://github.com/ArcadeMakerSources/ArcadeMaker (first of all, i want to say that I made this project for fun and challenge. I always wanted to create my own language. This has no business goal or something.) So the project is a 2D game engine (MonoGame backend) inspired by GameMaker 8. It includes its own IDE (built with WinForms) and an interpreted programming language that I wrote myself. The language—definitely the biggest challenge in the project—is a simple dynamically typed language. When I started, I had zero knowledge of how to build something like…
