Okay guys, quit the fucking flaming. Let's get something straight: if you were given a base, if you took some other guys' publicly released functions (or were given them somehow), if you used snippets that are available online etc. you don't have to credit anyone. You can if you want to, it's usually nice to do so, but you don't have to. Unless you leeched the damn hack.
And in the future please give credits to Microsoft for creating everything from Windows to Direct X, to the random guys who created C++, to the guys who created your compiler & IDE, to the guys who invented the goddamn RGB system.
Herp derp. That was sarcasm.
