the typical way to have a bouncing ball is to have x and y change
variables that are added to the current position when you wish to move
the ball.  when you bounce off of an edge, you negate the appropriate
change variable and the ball moves the opposite direction.  if you have x
and y changing by the same amount (x change = y change) then the ball
will move at 45 degrees.  to get other anges, make the change varaibles
be different values, for example, have the x change be 0 if the ball hits
the center of the paddle, 1 if it hits a little to the right, -1 if it
hits a little to the left, etc.
