Ok, I KNOW there's another API tutorial that is pretty good. But reading it's reviews, many people said it should of been more detailed. So I bring you this high-action tutorial explaining all there is to know about the fabled API!
Learn about the aspects, and how to integrade the actionscript code for the API into your Flash! This took a lot of work, and Flash froze quite a few times in the progress. I hope you all can start making some money from Newgrounds!
