A lightweight JavaScript implementation ofboids. Its 'API' is a little limited,but it's reasonably performant - my MacBook ran the demo with 1,000 boids at60 frames per second.

I used an earlier, hastier version for the flocks ingrow.

Installation

Usage

Download game enemy front pc full version. flock = boids([options])

flock.tick()

Moves the boid simulation forward one tick - if you're running an animation,you should be calling this on each frame.

flock.boids

All of your boids are stored as an array of arrays, with eacharray containing the following variables for a single boid:

Because the flock is just an array, it should be entirely safe for youto add and remove elements without any unintended side effects, provided allof the arrays are at least 6 elements long and contain numerical values. Forexample, you can add a new boid moving at a random speed to the origin like so:

flock.attractorsKnockout kings 2002 soundtrack.

You can use attractors to control the flow of the boids - essentially,providing them with goals and obstacles. Each attractor contains:

Note that you can use a negative value for force to repel boids instead ofattracting them. Again, it should be safe to modify, add and remove thesearrays without any surprises.
