In general, staying on the purely functional side will most likely kill your performance. You will need some mutation (I'd like to be proven otherwise, though). And not mutation via refs and so on, but mutation in the Java sense. So you'll have to create some Java classes for your game objects
It's possible to generate those classes from Clojure via gen-struct (http://bit.ly/mHzkX), which is a modification of genclass.clj. -Roland On Aug 30, 6:01 am, Elliott Slaughter <elliottslaugh...@gmail.com> wrote: > Hi, > > I'm visiting from the Common Lisp game-dev crowd and wanted to try out > Clojure for writing games. > > I saw some JOGL examples posted in this group, in addition to the > cloggle library which wraps some JOGL functionality.
