At work it happened I needed to make a game in flash (omg) and stumbled upon Flixel. I liked it and decided to port it to Java and Slick, calling this port "Slixel" (please appreciate the imaginetiveness). It's a port of version 1.5 and something, while now Flixel has been updated to 2.0 with improvements etc. that I will try to catch later.
All the code is available at this git repository:
(snasalapatty being an older project of mine).
Included is also the code and some artwork for a platformer game I'm making in the while, which should serve as a "tutorial". Almost everything has been javadoc-ed in english, while the majority of inner comments are in italian.
The whole code is under GPL, which may be not appreciated by someone. I'm open to relicensing it, later, but at this stage I prefer people to be "forced" to collaborate when solving the bugs that are still around:)
Hoping this would help the community, I wish you all a good night!
