hey,

i consider myself a newbie in as3, hence, i bump into a lot of problems. here is the latest:

main.swf has Main.as as document class

```auto

package 
{
	import flash.display.Loader;
	import flash.display.MovieClip;
	import flash.events.Event;
	import flash.net.URLRequest;
	
	/**
	 * ...
	 * @author sQrt121
	 */
	public class Main extends MovieClip 
	{
		
		public function Main()
		{			
			addEventListener( Event.ADDED_TO_STAGE, init );			
		}		
		private function init(e:Event):void
		{
			removeEventListener( Event.ADDED_TO_STAGE, init );
			
			// comment / uncomment the following line
			//MyStatic.doNothing();
			
			var _lLoader1:Loader = new Loader();
			var _urlReq1:URLRequest = new URLRequest("1.swf");
			_lLoader1.contentLoaderInfo.addEventListener(Event.COMPLETE, 

swfLoaded);			
			_lLoader1.load(_urlReq1);
			
			var _lLoader2:Loader = new Loader();
			var _urlReq2:URLRequest = new URLRequest("2.swf");
			_lLoader2.contentLoaderInfo.addEventListener(Event.COMPLETE, 

swfLoaded);			
			_lLoader2.load(_urlReq2);	
		}
		private function swfLoaded(e:Event)
		{
			addChild(e.currentTarget.content)
		}	
	}
	
}

```

1.swf has ClassOne.as as document class

```auto

package 
{
	import flash.display.MovieClip;
	import flash.events.Event;
	/**
	 * ...
	 * @author sQrt121
	 */
	public class ClassOne extends MovieClip 
	{
		
		
		public function ClassOne()
		{
			addEventListener( Event.ADDED_TO_STAGE, init );			
		}		
		private function init(e:Event):void
		{
			removeEventListener( Event.ADDED_TO_STAGE, init );
			
			trace( MyStatic.compute())
		}
	}
	
}

```

1.swf has ClassTwo.as as document class

```auto

package 
{
	import flash.display.MovieClip;
	import flash.events.Event;
	/**
	 * ...
	 * @author sQrt121
	 */
	public class ClassTwo extends MovieClip 
	{
		
		
		public function ClassTwo()
		{
			addEventListener( Event.ADDED_TO_STAGE, init );			
		}		
		private function init(e:Event):void
		{
			removeEventListener( Event.ADDED_TO_STAGE, init );
			
			trace( MyStatic.compute())
		}
	}
	
}

```

MyStatic.as is a “static” class

```auto

package 
{
	
	/**
	 * ...
	 * @author sQrt121
	 */
	public class MyStatic 
	{
		private static var nNumber:uint;
		
		public function MyStatic()
		{
			
		}
		public static function compute():uint
		{
			nNumber	+= 10;
			return nNumber
		}
		public static function doNothing():void
		{
			
		}
	}
	
}

```

when i test the main.fla, it traces 10, 10. if i uncomment line 24, it traces 10, 20. in other words if i dont make a referance to the MyStatic class in the Main.as (i.e the class becomes part of main.swf), i end up with 2 separate “static” classes.

finaly my question 😛 :  
is there a better way (other than making it part of the “supreme parent”) to create a “unique” static class that is visible everywhere inside a project no matter where u use it (first)?  
from what i know, i think the answer is “no”, but like i said, im no expert 🙂

additional info:  
ive been using swfaddress( a static class) in my projects for sometime now, but the supreme parent was always the main.swf. now im working on a project that requires a preloader - so this will be the supreme parent. inserting a referance (e.g a trace) to the swfaddress class inside the preloader.as doesnt seem that elgant to me…
