Fyrox (formerly Rg3d) is a Rust-based, open-source game engine for 2D and 3D development, prioritizing usability and performance. Its scene graph and visual editor simplify workflows, while Rust’s safety ensures robust code. Fyrox supports PBR, skeletal animation, and physics via Rapier, with 2D sprite rendering for versatility. It targets Windows, macOS, Linux, and WebAssembly, with mobile support planned. The editor offers scene editing, animation, and scripting in Rust or Lua, balancing power and accessibility. Ideal for indie developers creating RPGs or simulations, Fyrox is less mature than Godot but actively developed. Its clear documentation and GitHub community support learning, making it a promising choice for Rust enthusiasts.
