This is what I wanted to do a few days ago when I thought “Oh, what the hell… Let’s clean that code up before uploading it…”.

So I started moving some code around and after a few minutes, I found myself rewriting the whole thing… That’s not a bad thing since now we’ve got one handy class that can do about just everything a Bezier Animator should be able to do. :-)
Demo time!

Bezier Animation Demo

There’s still a little bug somewhere which allows the target to ‘run away’ from the bezier, and I haven’t gotten quite to the root of the problem, but I really felt I had to share this. Also there are some imperfections when you disable the orientToPath and scaleByPath properties. I will look into fixing those asap.

I really love the idea of animation movieclips using bezier curves. It looks so natural and yet zo intriguing… I will do some experiments and upload them later on, showing the coolness behind this simple animation engine.

It was great! I had such a great time. I met a lot of intresting people and although Amsterdam turned out to be quite expensive place, I really liked being there a few days.

During the conference I attended Joshua Davis‘ session which really inspired me. I’ve never seen Joshua Davis present, nor did I know his work. Let me be as crystal clear about this as I can be: The man is a freakin’ genius!
During his session he showed a few demo’s of bezier animated stuff. I felt like trying that myself, and this is what I came up with.

The basic concept is to create a bezier in Actionscript and animating movieclips using the bezier as its motion path.

  • Basic principle (this is actually just a basic pentool (without the option of adding new points :-P ))

The following versions use the same concept as this one, except instead of fixed anchor points, they all use random points defined in 2 planes. This makes a bit of variety possible allthough the main animation stays the same and that’s absolutely cool!

I added a few keyboard controls to give you some control of what is happening

  • spacebar = show the handles
  • r = clear the bitmap
  • p = pause the animation
  • n = randomize handles
  • b = blur more
