I've just started working with the great Flint Particle System and am already too lazy to always write down it's Constructors, as you can imagine when seeing the following:
var lZone:LineZone = new LineZone(new Point(5, 10), new Point(40, 30));
Phew.. :) These Zone-Constructors have made my fingers hurt, so I wrote them down as Templates for FDT. I am totally sure there will be more of them very soon as I continously will learn more usages, so sometimes this article will be pushed to the top of the index. Now you know. Besides I am trying to publish a Project Template for FDT4 with some of Flint's basic setups soon. Aiden Tailor has already made a Tutorial on this topic.
