I STFW and found quartzcore at svn.gna.org. I'll look into how fuzzy logic and more specifically AI could better the system and maybe code something up using gnustep-fuzzy. Everything will be portable Objective-C and not dependent on other libs. I will look at your above stack of technologies tomorrow. I know a bit of OpenGL, a bit of Appkit and UIKit by writing a small iOS game and nothing about Cairo although AFAIK it has the same interface as SDL which I do know something about as I wrote some games with it (mostly 2D not using its OpenGL.) Could you explain the reasons why CA,CG and OpenGL are Cairo-based ? I guess writing such things is very time-consuming without Cairo but it is more of a Gnome library. Anyway, I'll try to respond with some code for my quartzcore thingies in the next couple of days. This is probably the renderer I was looking after. Do try to explain me as why Cairo as this was a remake of SDL and has probably grown the last time I saw its API due to e.g. SVG and is now heavy-weight. To be fair I need some time to absorb all this. Thanks, `Enry
