🦢 The boids flocking simulation in Wasm using Ebiten!

Boids with Go and Ebiten

My blog post: Boids in WebAssembly Using Go

👉🏻 Demo link to the WASM version.

I wrote this program, an implementation of Craig Reynolds' Boids, in order to learn more about deploying Go on the web, and to tackle a problem that escaped me when I was learning to code!

Possible improvements

• Field of vision support (boids shouldn't look behind 👀)
• QuadTree optimization
• Different maxSpeed/maxForce for each boid
• Graphical interface for live-editing of values
• Use a snapshot for each 'generation'
• ..

Run 🦢

go run main.go

Build 🕊

GOOS=js GOARCH=wasm go build -o dist/boids.wasm github.com/healeycodes/boids

This compiles the program into WebAssembly in the dist folder.

The simulation can be viewed in a web browser via index.html. To get this working locally, you may need to serve the files from a web server.
