Smoothness

I''m assuming that your doing a little "If LeftKey then x = x - 6" type thing.. if so.. you might want to use a little ''speed'' (i can''t think of a better term).. for example.. each loop the x value of the paddle is increased by the ''speed''. As you press the right arrow key, the speed value is increased, and the paddle goes faster.. you of course can have a limit... and the left key will decrease the speed value.. every game loop you can then decrease the speed to simulate ''friction''.. here''s an example in basic (sorta).. FRICTION is how much you want to slow the paddle by.. and ACCELERATION is how fast you want it to speed up..

Do
x = x + sx
if sx > 0 then sx = sx - FRICTION
if sx < 0 then sx = sx + FRICTION

if LeftKey()
sx = sx - ACCELERATION
elseif RightKey()
sx = sx + ACCELERATION
end if

Loop

That should help with the smoothing problem.. you might also want to add a limit to how high sx can get.. and make sure their nice numbers or you''ll get all kinds of funny effects... hope i was of help..

Yeah, sounds like a nie solution.. thanx
