If you’re looking for a place to find some useful chunks of ActionScript, complete with full code and examples, you probably should keep an eye on Paul Orchanian’s blog, reflektions.miniml. He’s got some good samples over there for tricky things, including a lot of 3d code.

It takes a lot of effort to keep a blog like this regularly updated, and I can tell you from my experience that the authors are usually only doing it for the reward of helping people out. Paul is a great guy - I had the pleasure of meeting him at FITC in Toronto last year and in 2004. So head on over and check it out.
