Sprite Animation Toolkit is a 2D animation library that I created in the early 90's. It was very successful in those days, being used as base for an enormous number of games and educational software, mostly shareware products.
After the millenium, the future of OS9 was dark, OSX was rolling in and I had to move there. I created an OSX version then, but I was never really happy with it and the games I ported got little attention, most likely because they didn't run as smoothly under OSX as they did in OS9. Later, I have found out that the problem was the event processing in OSX. The whole project also felt very outdated. Writing sprites fast was no longer an interesting problem and even the wrong way of doing things.
More recently, starting 2009, I rewrote the library from scratch, this time using OpenGL. Some changes were made in order to make it portable as well as more modern, fully allowing rotation, better collision detection, etc. By switching to FPC, I use a much more modern and capable compiler, simplifying many tasks that were awkward in the past.
I have written some test games with it and now it feels back on track in a way that the 2002 version never did. I am still not sure if this matters the way it did back then, but at least I will use it for my own games.
Preliminary SAT version are available in the download section.
