No, I remember this guy. He is a troll. He left for a few months, and now he's back.

MPG i am sorry but i never heard any compilers out there that let's you put semicolors everywhere like that. It looks like you are writting your own language or something. I am not flaming you or anything, just wondering what is the name of the compiler htat you using

If you don't know why you code like that, you don't know the basics (since your code is indeed very basic). I really would suggest learning C/C++ more fully before trying game programming. The little red fellow on my shoulder is also urging me to tell you to try Allegro instead, but I'll refrain. [smile] I don't think it will help anyway.

I'll leave the thread open, but really, this isn't going anywhere. Go learn the basics, rookie.

Jesus saves ... the rest of you take 2d4 fire damage.
