In the Flint particle system the initial velocity for particles is based on a zone. Because we can make zones from bitmap data objects and display objects it's relatively easy to create effects like the one below. The initial velocity for the particles uses a zone derived from the logo image. Add a little gravity and blur and this is the result.
I'm doing a presentation about the Flint Particle System this Thursday at the London Flash Platform User Group. As well as showing how to use Flint to create particle effects I'll be delving into the underlying code architecture and showing how to customise Flint to your own requirements. I'll also be looking at some of the specific problems I encountered and solutions I employed in developing Flint so hopefully the talk will be of interest to any developer, not just those who want to create particle effects...
