This little test app shows the Tweener library for moving bits around. Each dog moves using a different easing method.


This swf comes with the Tweener doc, and shows the available easing functions. You can click each curve to see how it will move.

The Tweener library itself is super simple, this video tutorial shows how to use it. The trickiest part is that the place in FlashCS3 that you specify the locations of external class libraies is hidden in the basement with a Beware of the Leopard sign.

The global path list is at:
Edit->Preferences->ActionScript->ActionScript 3.0->Classpaths.

The per project classpath is at:
fla properties->Publish:Settings->ActionScript Version 3.0 Settings->Classpath.

I always use the global list. Much simpler that way.

There are several good AS3 tutorials here, which I found while trying to figure out sound. Strangely, I had a lot of trouble finding material on sound in AS3 until I found that site.
