Sometimes it’s good to break things…

During a recent project I needed to find a way of simulating digital interference on an image / video stream. At first, it seemed the best approach might be to use the graphics API or Bitmap effects, but why imitate when you can have the real thing. Read : Smack My Glitch Up »

I’ve been revisiting one of my favourite topics lately – recursion – and have been getting together a bunch of sketches for a big personal project I’m working on (more on that another time). Anyway, I inadvertently stumbled across quite a nice way of making things grow in a convincing manner, and whilst this script doesn’t actually use recursion ‘per se’, I thought it was kind of cool so I ran with it.

I’ve uploaded the Boid source code. Sorry for the delay. I’ve also included some basic examples of how you can create nice behaviors using the Boid class. If you set Main.as as your document class then you’ll see that within that you can specify the demo to run when you compile.

The basic demos included are:

• Chase – Boids chase each other
• Flock – Boids flock together with some wander
• Graphics – How to use custom graphics with a Boid instance
• Seek – Boids seek the mouse position
• Wander – You guessed it, they wander

I’ve commented all of the methods and properties and there is also documentation (open index.html in the docs folder) to get you started. Before you mention it, yes, there is some redundant code ;) (such as the constrainToRect method which doesn’t really work) but I need to do some optimisations anyway so I just left it as is for now, rough and ready.
