flixel is a free Actionscript (Flash) library that I distilled from a variety of Flash games that I've worked on over the last couple years, including Gravity Hook, Fathom and Canabalt. It's primary function is to provide some useful base classes that you can extend to make your own game objects.

HISTORY
=======================================================
Adam started working on Flixel in March of 2008, and released the first public version in June 2009. Probably the most commonly asked question about Flixel is "where did it come from?" so we've included a short explanation here:

“I tried a few different times to make a little game engine type thing that would allow me to make retro games. That just seemed like a fun thing to be able to do for fun on a weekend. I tried it in C++/Python/OpenGL right when I left school, maybe 7 years ago? Anyways, it was a failure. Once ActionScript 3 came out, I was able to do some of the pixel-level stuff that I was really interested in. However, by the time I got my hands on AS3, I was more interested in just making little games, and seeing what patterns evolved. I kept making more complex games by reusing the code from the last project, and eventually those parts that I was seeing in every project got moved to their own folder. I think a lot of coders out there have a folder like this on their hard drive somewhere.”
