Custom classes communication

1

do you communicate among a 2nd or more level of classes?

Lets say I have this Main.as, I imported in Logo.as. And I have this Shadow.ac classes that I wanted to apply on to several classes too.

Main.as
ActionScript Code:

If I put it all under 1 as file, it would be no problem detecting the target, but now I’m separating the classes and loading all into “main.as”, how could 1 communicate with other classes without having to put it all together?
