Extend classes / split up [AS2]

1

Hi everyone.
I’m trying to learn to extend/split up my classes. For example say that I have a preloader, I want to load different things different ways so that’s why I have several loading functions.

What I want is to have the base preloader that holds functions that all preloader functions can use. Then I want all the different loaders functions in different classes.

Preloader.as

  • Preloader_preloadIntroElements.as
  • Preloader_loadSwfs.as
  • Preloader_preloadMovies.as

How schould I solve this?
I started a little like this:
[COLOR=Red]Preloader.as[/COLOR]

import com.broadcaster.EventBroadcaster
class com.loaders.Preloader extends EventBroadcaster{
    function Preloader(){
        //some things
    }

    function preloadIntroElements(){}
}

and then in the [COLOR=Red]Preloader_preloadIntroElements.as[/COLOR]

import com.loaders.Preloader
class com.loaders.Preloader_preloadIntroElements extends com.loaders.Preloader{
    function preloadIntroElements(alot of values){
        // Do all loading stuff
    }
}

The problem is that I cant get to the Preloader_preloadIntroElements.as class. it stays and just runs the preloadIntroElements function in Preloader.as
