So I'm trying to make a game of Pong over Rednet and I thought that making this would be simple, but I was wrong apparently!!!
I made a tiny piece of code to test the ball bouncing physics, but the X axis didn't move.
I made another program to test the movement of the numbers
This is basically what I did:
while true do
local x, y = term.getCursorPos()
term.setCursorPos(x+1,y+1)
print((x+1).."/"..(y+1)
end
when I did this, I noticed that the X integer did not change! The Y Integer changed but the X one didn't. Can I be told why this is?

Please post the code of your bouncing ball physics.

The first problem I see is xpos / ypos aren't defined anywhere, yet you add or subtract from them.
Besides that, it's unnecessarily complicated with if statements. Why not just set LR to -1 or 1, and add it to xpos?
Eg:
local xpos, ypos = 10, 10
local xmotion, ymotion = -1, 1
while true do
if xpos == 1 or xpos == 51 then
xmotion = -xmotion
end
if ypos == 1 or ypos == 19 then
ymotion = -ymotion
end
xpos = xpos + xmotion
ypos = ypos + ymotion
end

For future reference, print causes the cursor to go to the beginning of the next line. If you were to use term.write instead of print your example would work (your bouncing ball program might even work, haven't actually looked at it).

Not to do with the problem you're having, but I would also recommend moving your drawBall function out of and above the while loop.
