Document Class + Preloading + Export on 1st Frame

Hi everyone, long time no post :slight_smile:

After recently (finally) migrating to AS3, I’ve been having a problem with preloading and document classes…Say I have a library full of sounds and movie clips that are set to export for AS, and I’m also using a document class. If I want to preload, obviously I need to change where my library assets export (eg, not the first frame).

How do I get this working properly? I tried unchecked “Export in 1st Frame”, then on frame 2 of the stage I put all my assets inside a movieclip…but in my document class when i try play sounds from the library it doesnt work?
