There really is no way around this. We preallocate space for all our OpenGL vertex, as well as all the FSM for the AI engine. This is something we do even in our C++ code. We avoid creating objects whenever possible, and preallocate at init time. This is especially true in devices with smaller footprint like console/iphone/android, etc. Having said that, for prototyping OpenGL realtime 3d stuff on our desktop, clojure has been ok. > 3.

I'm not sure what you mean by this, can you expand on this? -- You received this message because you are subscribed to the Google Groups "Clojure" group.
