A custom, hackable 2D Game Engine written in C.
Check out the hand-crafted documentation website here.
For advanced C developers, you can generate Doxygen documentation with doxygen Doxyfile in the engine directory.
Yoyoengine started as a small game in SDL, and evolved into a fully featured, general purpose 2D game engine.
Feature List:
- Easy to use visual editor
- Multi platform support (Windows, Linux, Web)
- Basic Networking through SDL_net
- Asset bundling by default, for optimized builds.
- A plugin system, with a few premade plugins for things like Discord RPC (see yoyo-rpc)
- Generic Gamepad and Controller abstraction layer
- First class Lua scripting support, with native C scripting for complex or performance critical tasks
Tech Stack:
- SDL2 (windowing, rendering, audio, input, networking, etc)
- Nuklear (UI)
- Uthash (Hash tables)
- Jansson (JSON parsing)
- Lua (Scripting)
- Custom Entity Component System
- Custom binary packing format for assets, with zlib for compression
- Custom physics and collision system
In May 2023, I started working on a visual novel game in SDL2 as a way to learn C for the very first time. While I have yet to finish that game, the dopamine loop of working with a lower level language quickly spiraled me into a scope creep grind, and I ended up with a fully featured, general purpose game engine.
I work on random projects of interest, and occasionally build games with this engine.
