How can I change Nested Class in actionscript 3 - actionscript-3

Question

I'm working off an actionscript 3 code that pulls information from other actionscript 3's. The main code is Herbfight and it references 4 others (Bullets, bugs, Goodbugs and Sprayer). Below I'm trying to combine them all into one actionscript. The reason for this is that I want to pull it in as a symbol rather then having the flash file relate to the class.
The problem is it says I can't have nested classes. Any thoughts on how i can fix this? Below is my attempt to combine the code.
Thanks,
J
