This project initially started for learning Vulkan but quickly grew into a full-fledged game engine with which I write my games with.
This is a monorepo and contains both the engine (in edbr
directory) and various games/test projects (in games
directory).
The article which explains some implementation details: https://edw.is/learning-vulkan/
Playable demo of cat adventure game: https://eliasdaler.itch.io/project-mtp-dev
- Vulkan SDK
- CMake 3.21+
- Linux: whatever SDL2 needs
This is a "source available" repository and not open source (yet). Feel free to look around and use code for inspiration. When the time comes, I might release this under a more friendly open source license (possibly even public domain).
Feel free to open issues if something doesn't work.
Sorry, but I currently won't accept any PRs until the project has a real license. It might be hard to re-license it later with external contributions.

env variable to where the cloned repository is or pass --dev
flag when launching a game.
