O:\ICT\ks3\scratch\scratch Exercises\Creating a Pong game

First Create the stage

Edit the background to create the out area

Now draw your two sprites

On sprite to grab the instructions needed.Connect them up.

Begin start and stop command(make sure co-ordinates are right for top of your screen)

Click the colour in touching colour and

then click red band at bottom

Change the direction by pulling point straight down

To prevent ball going off side if screen set the if on edge bounce function

•At this point your ball should move from left to right and your paddle (sprite 2) should move with your mouse

Now we set the ball to bounce off paddle

These are commands that are needed

This will get ball to bounce off the paddle

Pick random will make ball move in random directions

Make sure values on screen is same as mine
