Crate crayon

What is This?

Crayon is a small, portable and extensible game framework, which loosely inspired by some amazing blogs on bitsquid, molecular and floooh.

Some goals include:

• Extensible through external code modules;
• Run on macOS, Linux, Windows, iOS, Android from the same source;
• Built from the ground up to focus on multi-thread friendly with a work-stealing job scheduler;
• Stateless, layered, multithread render system with OpenGL(ES) 3.0 backends;
• Simplified assets workflow and asynchronous data loading from various filesystem;
• Unified interfaces for handling input devices across platforms;
• etc.

This project adheres to Semantic Versioning, all notable changes will be documented in this file.

Quick Example

For the sake of brevity, you can als run a simple and quick example with commands:

git clone git@github.com:shawnscode/crayon.git
cargo run --example modules_3d_prefab

Re-exports
