I have seen a couple of posts recently from people looking for some information on integrating AS2 and AS3 code. I recently worked on a project that I ended up spending quite a few hours trying to get some things to work right so I figured I should post about it. Hopefully someone will find it useful.
So I wrote a Flex application that I was able to knock out fairly quickly. The core framework really made a lot of the grunt work disappear and I was pretty pleased with what I had. It was only when I was done with the application itself was I informed that the application was supposed to be loaded in an AS2 swf. Ah well, I could always loadmovie it.
Just when I was ready to quit and about to just port the whole app to AS2, I tried going completely out of the flash player to get my application to show up on top of the base swf. Go html positioning. I ended up writing both the swfs into 2 separate divs using swfobject and then absolutely positioning the base swf and relatively positioning the container with the Flex application on top of it.
The css styles looked like this:
Works pretty well :).
