A simple bat and ball project which forms part of the redware lesson plan for learning Scratch.
Use the up and down arrows to move the bat and hit the ball. This game needs to be extended to have a score. Add a colour or sprite to the back wall to allow the computer to win and score a point each time you hit the ball.
You can view a video on how to make this game (and others) at www.redware.com/scratch/videos/batandball.
