One in & out transition for several external .swf's

Hi,

I’m trying to do a transition that applies to all the external .swf’s that will be loaded into an area in the main movie, which basically “eats” the current external .swf and then opens to show the new chosen .swf.

Therefore I have one problem:

the Actionscript needed for both the buttons and for that transition clip, in the middle point. By middle point I refer to that point where it has just “ate” the existing .swf and will now start to display the chosen .swf

So I would need something like - on hitting a button, it telling the movie clip to be placed in an imaginary level or something like that, and then I’d place an action in that middle point of the transition movie clip, to display what’s on the immaginary “level”. Until there, the previous .swf is visible (though the transition is sort of “eating it”, hehe)

I know there are some threads with situations that are alike, but I haven’t found the same type of situation… :s

Thanks in advance
