Pass var value between classes

Hi Andrei1. Thanks for the explanation and examples. But I am having trouble getting this to work. It should be stright forward enough but I still can't get my head around it.

What I have done is make a fla with one mc on it.

Have linked Quotes as file to it.

All three files are in the same directory

When I test it there are no errors, the text in the Output window is '0 quotes'.

Here is the code for both Quotes and DayOfYear as files

Package for DayOfYear

package
{

public class DayOfYear
  {
    public var numberDay;
  

  public static function get getDayOfYear():int {
        var tmp: Date = new Date();
        var t1:Number = tmp.getTime();
        tmp.setMonth(0);
        tmp.setDate(0);
        var t2:Number = tmp.getTime();
        var numberDay:int =  int((t1-t2)/86400000);
        trace(numberDay + "DayOfYear");
        return numberDay;

    }
   
  }

}

Package for Quotes

package
{
import flash.display.MovieClip;

      public class Quotes extends MovieClip
      {
            private var _dayOfYear:int;

 
             public function Quotes()
               { 
              trace(_dayOfYear + "Quotes");
               }

         
               public function get DayOfYear():int { return _dayOfYear; }
       
               public function set DayOfYear(value:int):void
               {
                       _dayOfYear = value;
               }

     }
}

It seems that when I test the file it does not read or use the DayOfYear class.

Appologise if I am asking something obvious, but I cant see what I am missing.

First of all, constructor function must be the same case as class name. You have constructors starting in lower case and class names with upper case:

 

 public class DayOfYear extends MovieClip 
 {
      public function DayOfYear() 
      {
      }
 }


public class Quotes extends MovieClip
 {
      public function Quotes() 
      {

      }
}

Second. If your class DayOfYear's responsibility is to retrieve the day, why does it need to extend MovieClip? It can perform as asked without being a MovieClip unless you plan to to write a code that will display something.

As for passing values, it depends on how you intend to use it.

In essence, DayOfYear can have a static method that returns the day. Inside DayOfYear:

 
public static function get getDayOfYear():int {
     var tmp: Date = new Date();
     var t1:Number = tmp.getTime();
     tmp.setMonth(0);
     tmp.setDate(0);
     var t2:Number = tmp.getTime();
     var numberDay:int =  int((t1-t2)/86400000);
     trace(numberDay);
     return numberDay;
}

In your Quotes class you need to create a method and property that accept the value of day. Your Quotes class may look like this:

package 
{
    import flash.display.MovieClip;

    public class Quotes extends MovieClip
    {
         private var _dayOfYear:int;
         public function Quotes() 
         {
               
         }
          
         public function get dayOfYear():int { return _dayOfYear; }
         
         public function set dayOfYear(value:int):void 
         {
             _dayOfYear = value;
          }
     }
}

Here is a fork. If you want every instance of Quotes have the same day value, you might want to just read it directly in the quotes:

 
public function Quotes() 
{
     dayOfYear = DayOfYear.getDayOfYear;
}

In addition you can set the day when you make an instance of Quotes:

 
var quotes:Quotes = new Quotes();
quotes.dayOfYear = DayOfYear.getDayOfYear;

If you make method getDayOfYear NOT static - you will need to make an instance of DayOfYear class and then call this method on this instance - not class itself.
