Snake

[equs]

hi i need some help with my program. The snake only grows when you clikc in the opposite direction its going in and i also want to make food grow afteryou collect good food, and this food is that when you collect it you die. PLease help me thx.

SHAME ON YOU!!!
http://www.compsci.ca/v2/viewtopic.php?t=3625&highlight=snake

You asked for help to do snake on April 9th. Paul Bian told you to look at SantaBruzer's code. You copy it almost exactly then ask for help to fix it, and claim it is your own.
SHAME ON YOU!!!

palagurism is bad. you should lose bits.

Why don't you take a look at my snake game? It may answer some of your questions. I am almost done. So far im just polishing it up. Right now I am adding lives, speed, and other stuff which will remain a secret

It will be ssoo good. Everyone will donate all their bits to me and i will be the king of all. MUAHAHAHAHA

im trying to fix it becuase i want to see how to fix it.
