For whatever game you''re making, to evolve the networks (weights, morphologies, whatever) you''ll either have to play it over and over again, have it play itself or, if you have a population in a persitent world, just leave it running for a long time. Turn all graphics off and set it going and it should find some decent settings eventually. Don''t be dispondant if it stops increasing in fitness for a while (minutes or even hours) that doesn''t mean it''s got to an optimum, it may just be waiting for the right mutation.
