may I be able to use the knowledge that I have now in AS2 with flex? Or is a kinda thing where I have to learn again due to diferences? I mean, attachMovie and variable declarations still working the same in Flex or is another way there?
I´m wondering if a swf would be attached here and how???
mm well variables declarations are same, u dont have attachMovie and other MovieClip factory methods, you can use constructor insted ( new MovieClip)
check the ActionScript3/flex2 documentations, you'll find almost all changes there.
