Summary

RaZ comes from, as you may have noticed, my username Razakhel. This was also meant as a pun, since in french RàZ is the acronym for "Remise à zéro", which basically means "reset". I didn't have any particular intent behind this double meaning. Except maybe hoping that using RaZ might reset your mind because of its awesomeness? Oh well.

Written in modern C++ (17), ECS driven, it is primarily developed for learning purposes. It is intended to be as optimized as possible, while trying to stay as modular as it can.

The engine is available under Windows, Linux & macOS; it can also run in a web browser through WebAssembly (using Emscripten).

🖥️ RaZor, an editor also multiplatform, is available to manipulate the engine through a graphical interface.

💬 A Discord server dedicated to RaZ & RaZor is also available! Feel free to come by to follow the development, ask any question, or just say hi 👋
