There are many examples covering various aspects of the engine. Also don't hesitate to create an issue if you need help!

Frequently asked questions

Q: Is rg3d using ECS?

A: No. It is using more classic OOP approach. However, it uses lots of optimizations for efficient memory management such as generational pools.

Q: Examples running too slow on my PC, FPS is too low, help!

A: At first, make sure you run examples on discrete GPU, not on a built-in of your CPU. Built-in GPUs are very slow and not suitable for rg3d. Secondly, make sure your discrete GPU is powerful enough to run modern games at decent frame rate.

Supported Operating Systems

  • Windows - full support
  • Linux - full support
  • macOS - full support
  • WebAssembly - not supported yet: any help is appreciated.

Compiler version

rg3d require latest stable Rust compiler.
