I have been busy re-writing our AS2 libraries to AS3 this week and encountered something that will easily trip up most people. And of course I didn’t see it in any documentation anywhere. Basically the issue is that in AS2 when you navigated to a frame using mc.gotoAndStop() you would have access to all the elements on that frame. But now in AS3 they aren’t available right away. I found a great post by Senocular that explains this and shows the solution. Check out the post here.
