   I've currently got the following code:

   However to create the "container" for my particles I'm just butted lines up against each other. I realize this isn't a very elegant solution, can I use BitmapDataZone to accomplish the same effect using the following bitmap and if so what would the code look like?
   
   here is a link to the bitmap I am hoping to use.

   thanks

   You could use a single BitmapDataZone but the collision resolution will be less accurate - particles will be retained in the zone correctly but the angle of collision with the walls will be less accurate. Your code would look like this -
   
   emitter.addAction( new CollisionZone (new BitmapDataZone( bitmapData ), 100, -400 ) );
   
   You could also use a MultiZone to combine all your line zones into a single zone.
   
   var mz:MultiZone = new MultiZone();
mz.addZone (new LineZone( new Point( 100, -400 ), new Point( 100, -40 ) ) );
mz.addZone (new LineZone( new Point( 380, -400 ), new Point( 380, -40 ) ) );
...
emitter.addAction( new CollisionZone ( mz ) );
   
   This won't affect the performance of your code at all, but you may prefer the concept of a single zone made from all the lines.
