Using an external class to reference functions from another external class

Hey guys. I’m new to classes, sorry to be so dense, but I cannot seem to find any help on referencing external classes from other external classes. I’ve found help for classes referenced from main timeline, and document class tutorials, and a slew of other things, but nothing specifically for my issue, and no matter what I do I can’t figure it out.

Simply put I have a Main.fla which loads Main.as as its document class. In Main.as I have a public function named “Main” which runs a trace. I also have another .as file called Preloader.as, which also has a public function in it, this one named “Preloader” with simple trace in it.

I just cannot figure out how to use Preloader() from the Preloader class in Main() from the Main class. Main.as loads up fine when the SWF loads and traces.

Again, I’m new to this and I have looked pretty thoroughly for anything to do with “external classes” and cannot find anything. Any help is appreciated.

Thanks in advance.
