  Looks cool and promising.

  I made a class in your zone package in order to use a bitmap as a zone. The particles will not be create on a transparent part, this means you can use all the shapes you want for your particle emitter zone.
  It’s not optimize and it was simple to do, but seems to work well and it can be usefull (at least for me :p).

  I will try to send it to Flint (if i find his mail somewhere) or just send me a mail at : [email hidden]

  Please do send me the class. It sounds very useful and I’d like to include it in the next update.

  I’ve sent you a private email so you know where to send it to.

  Ok, i finally finished my first test :

  I just add the removeFilter function in the BitmapEmitter class. (already send you by mail).

  Ho and i was just thinking that it should be easy to put any displayObject (Sprite, MovieClip, …) as a zone.

  i update my test again, before with “steady(600)” even without blur i was really slow. I add a fonction to upgrade my fps, its working only in some situations, but for my exemple i can now have a “steady(2000)” with blur and i steel have a better fps than before

  There’s now a DisplayObjectZone and a BitmapDataZone checked into svn. They’ll also be in the next download when I get that out.

  Couldn’t you put all the transparent points found in the first loop in an array and just take a random index in the getLocation().
  The getLocation can be slow if the picture is a lot transparent, and i read the getPixel32() is not really fast too.

  I also work a little in a way to group all the particules with the same comportement in a group in order to improve performance, that was the idea, its actually working for me, but i should find a better way to do it.

  getLocation returns fractional numbers, but the first loop to calculate the area is based on uints only. So it would require the compromise that getLocation always returns an integer point. I guess that wouldn’t matter if the speed increase is worth it, which it probably is.

  hi! i translated the documentation about the library at http://www.fuoridalcerchio.net/wordpress/tutorials/flintparticle/

  i hope this doesn’t bother you. please let me know if you need an italian translated reference to the lib.
  thank you.

  Very nice. I like that a lot. If you want to distribute the source code I can put it in the examples on the Flint website or you can just post it in the forum on the site.

  Hi! I made a tutorial for making a Basic Starfield with Flint System. Some more are coming.

  Check it out at http://www.fuoridalcerchio.net/wordpress/2008/03/09/creating-a-simple-starfield-with-flint-particle-system/

  Enjoy!

  Man does that look awesome, I love the colors and symmetry, one of the many reasons I love particle coding so much. Thanks for sharing, excellent job.
