Please help ,i’ve installed flex 4.6 and i’m trying to compile Basic_Fire.as from the examples folder ,I receive no error but i’m getting an empty browser page with no result
This is my code in flex

<?xml version=“1.0” encoding=“utf-8”?>
<mx:Application xmlns:mx=“http://www.adobe.com/2006/mxml”
  xmlns:local=”*”
  layout=“absolute”
  width=“500” height=“400”
>
  <local:Basic_Fire>
</mx:Application>

Could someone paste the proper code to compile the class or any class from away 3d in flex??
In flash i would just go to properties and add the class
How can i do the same in flex?
Many many thanks ,

May be you need to add:

backgroundAlpha=“0”

something appear ?
