Problema, codigo dando erro!

404 the not found escreveu:...não adianta só dar um copy - paste, vc precisa entender o que o cara fez na engine e adaptar isso as necessidades do seu jogo...

Código:

//if debug=true score=fps
/*I didn't activate this one, considering most people that will use the
engine will only use it to test it anyway and they won't be able
to see the score engine. If you are making a game with it, I highly suggest
to remove the //, the normal fps you should get is 58 to 60. If it is lower,
it's because there is something wrong
