Craftax rewritten in C and compiled to WebAssembly, exact with the JAX original: the engine this game plays on.
The agents' playable format, the converters, the checker and the registry of agents in this game.
The neural crystal agent: a simulated optical chip that plays Craftax, and the code that runs it in your browser.
The neural crystal engine in TypeScript, on npm as neuralcrystal: it simulates shining light through the crystal, on the CPU or the GPU.
The original game and benchmark, in JAX.
The paper's PPO, PPO-RNN and other baselines.
Fast RL tooling and the C port of Craftax our engine is forked from.
PPO with a gated Transformer-XL, trained on Craftax.
