This is a simple Pong clone I wrote for some practice with the Bevy game engine and Nix. It serves as a simple example of how use Nix to build Rust packages for webassembly, letting Nix manage the toolchain and other dependencies. Right now the AI plays perfectly and never misses, I haven't managed to score at least. Tweaking the difficulty is the next goal.

To run the game locally using Nix, use the following command:
nix run github:mith/pong
Should it somehow be your deepest desire to contribute to a pong game, setting up a development environment is easy thanks to Nix and Direnv; run direnv allow in the source directory and any shells and editors with support for direnv will have the toolchain and tools like rust-analyzer linked into their environment when opening the project.
