Question about code placement!

Hi, unfortunately i don’t have a specific piece of code that i’m searching for help with(and sorry if this type of thread has been made before >.<)… I’ve just been wondering how other as3 users utilize the timeline for code placement versus external AS files. I’ve only made a basic shooter game with upgrades so far and most of the code was in my gameController class; with pretty minimal code on the main timeline. After a while i looked back on it and thought i might be doing it “wrong” or not optimally. Just curious as to how others do it, particularly for larger projects/games. Thanks :smiley:
