Scratch

There are many ways to let a sprite move randomly across the screen. For a 'Pong' type of game you probably wouldn't want your ball to move completely at random, but rather to start off in a random direction and bounce off the edges in a predictable way. So you could start by setting the ball-sprite's direction to a random number from 1 to 360. Then you could use a forever-loop let the ball move a certain amount of steps and bounce off the edge.

This will pretty much get you started. Now you have to think about a way to find out if the ball hits the bat or the bottom.... (hint: have a look at some of the pong projects around, I'm sure these will  give you some inspiration).

Hope that helps
