Just wanted to post a small update for those of you interested in the new particle engine. We've been pouring a lot of work into it, and I think it's coming out pretty great. This particle engine is actually our 3rd or 4th iteration. After experimentation and some research we've decided to base it on the popular flint particle engine. More on that later though.
Currently we're putting the finishing touches on it, and are hoping to release it as (public) beta in the upcoming days. Next we'll focus on documentation and tutorials and the like while it's being tested.
Another quick update: we have a branch up on github called particles-alpha which contains the particle engine (within PixelKit). There are no samples yet, but they are coming very soon.
If you've ever used flint though, it is quite similar.
