So the Tween/Transition stuff wasn’t put in the Flash documentation. Good news is that there’s now an article on the Developer Center about using the classes. Bad news is the article came from me
If you haven’t used the classes yet, check the article out out anyway, see if it helps you with your Flash work. Fairly simple article (had to keep that word count in check…)
If you have any ideas for expanding the content, or wish to share some of your own tips, please comment below.
