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 very intuitive & easy to use and tinker with, while trying to stay as optimized & modular as possible.

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

The engine can be used with Lua, a scripting language that is very simple to both learn & use. For more information, see the dedicated wiki page.

📖 If you want to get started with RaZ, head to the wiki. For the documentation, look over here!

🖥️ 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 👋
