holy Moses, you're joking right? What you're asking for is something that an 8 year old could figure out. We live on earth, we see gravity every day. Even the 8 year olds know that when they play with their balls, the balls constantly accelerate downwards, not upwards. Now obviously they don't understand those words, and probably neither do you, but they understand how shit works, which you apparently don't. Your code is extremely retarded. You are even more retarded than your code. I really hope you're joking because I'd rather think of you as an immense douchebag than a mentally handicapped person. I could figure this shit out on my own when I was 11 for god's sake.
Knowing that you're 13 years old or younger, I wouldn't be so harsh on you if it weren't for you acting like a total douche on the bbs. Go away.
