Osciallating Divs – Looking back at old code

Uncategorized, , ,

I went back and looked at some old code in an experiment with the GSAP (aka Greensock) animation library.
I and i thought – oh, wow, that’s how I coded javascript a few months ago. With a bunch of globals.
So I cleaned up the code hiding that nastiness away. And the code is now on github.

View the animation here on you desktop, tablet or phone.

Note that the animation plays  choppy on older mobile devices when the alpha is tweened.

Random Tile class

code, Professional,

Here’s an Actionscript 3 class I wrote the places tiles on a grid – either randomly or in order, with no overlap, and allows for a tile free zone.

You can see it in action here.
