The line thats giving me problems is:
rem if the number is less then 128 then the player 2 serves rem the ball, otherwise player 1 serves the ball if temp1 < 128 then ballx = 20 : bally = 45 : ballvx = 1 : ballvy = 1 else ballx = 135 : bally = 45 : ballvx = -1 : ballvy = -1
I don't see any problems wth the code with the exception of it being very long!
Sincerely,
Open Source Pong
