Start into Classes and references to Variables

Hi Guys,

Long time ago I’ve been creating some as 2.0 projects, all of them based on the code within the timeline.
I wanted to start learning as 3.0 based on classes rather on timeline but I find it confusing and difficult to understand introduction into the classes.

I can’t get to understand why the following example is not working :

I’ve got 3 files:

main.fla with main class “Main”


no code

Main.as

 
package  
 {
 import flash.display.MovieClip;
 import projectconfig.Configurator;
 
 public class Main extends MovieClip 
 {
 var projectConfigurator:Configurator;
  
  public function Main():void 
  {
   projectConfigurator = new Configurator();
[COLOR=#ff0000]   trace(projectWidth);[/COLOR]
  }
 }
}

Configurator.as

 
package projectconfig 
 {
 
 public class Configurator 
 {
  var projectWidth:uint = 1200;
  trace("Configurator loaded");
[COLOR=red]  trace(projectWidth);[/COLOR]
 }
}

Can anybody help me out how to use value of “projectWidth” from Configurator class in the Main class?

The [COLOR=red]code in red[/COLOR] doesn’t work and I can’t work it out why.

I’ve noticed that if I recode **Configurator.as **this way:

 
package projectconfig 
 {
 
 public class Configurator 
 {
  var projectWidth:uint = 1200;
  trace("Configurator loaded");
  [COLOR=blue]public function Configurator() {[/COLOR]
[COLOR=red]   [/COLOR][COLOR=black]trace(projectWidth);[/COLOR]
[COLOR=blue]  }
[/COLOR] }
}

[COLOR=blue]Changes in blue[/COLOR] - then the Configurator.as traces **projectWidth **value, but still I can’t use it in Main.as.

Thanks
