Please be nice and dont be mean to the code, https://code.stypi.com/neontails190/Game%20Block%20V1.lua I need help with the brickcolor random thing. Any one can help? Please don't mess with it. I'm gonna backup.
You forgot a 'wait' function.
while true do GB.BrickColor=BrickColor.Random() wait() end
A 'while' loop will more than likely, if it hasn't already, crash Roblox if you did not put a wait in it.
