Birbs

A boids implementation in Rust for WebAssembly.

Why?

Well i'm learning Rust and the boids simulation facinates me.

TODO

• It uses a quadtree to make looking up neighbours really quick but this results in undesirable clustering.
• Give the boids some form and make their direction clear (at the moment they're just 2x2px squares)
• Add some obstacles

Getting it running

At the time of development you'd need a nightly build of Rust (I was on 1.31.0 — if you find the project is no longer working on later version let me know!).

You'll also need wasm-pack:

wasm-pack build

This will generate an npm compatible package in the /pkg directory

Demo

The project comes with a demo to try things out.

From the root of the project you can run

yarn
yarn start

This will build a minimal demo (found in index.js and serve it up over a local web server

Tests

I'm still new to Rust but there are a few tests

cargo test

Demo

It's not hosted anywhere currently but here is a gif with 5000 particles 😉
