Particle Emitter

I was recently asked how my particle emitter worked on my game Bounce. This is a quick re-write of what it pretty much is.

It has some cool features which can reduce the GC been called as often.

* Cached colored particles (Current color)
* Recycled inactive particles instead of constantly creating new ones.
* Basic physics, could be improved.

Also please note I've squished some classes together, they're easy to redo so they have their own class.

Hope you enjoy and I look forward to seeing it used in some scenarios.

If you use it please post the link of the scenario below so I can see it in action.

Thanks :)

Thank you so much! I've been trying to replicate this with very little success.

If you no longer want particles to be emitted don't call the emit(x, y) method.

Wow, this is awesome! I really want to use it in some of my projects, but there's one thing I can't figure out: Where in the code do you make the particles drift off to the left? When I make the x and y forces 0, it still drifts left. I've spent the last 3 hours combing the code, but I still can't find it. Can you help me with this?
