Place two ‘set to’ block right under the event block, for each player. Then create another one and name it – player 2 score. Then go to the data category and click on ‘make a variable’. This will make the program draw an even circle, also, choose to have it filled. Click on the ellipse tool and hold ‘shift’ key while drawing a circle. I will use them as indicators for counting points. Before we create the bouncing ball sprite, click on the backdrops, go to its costume tab, and draw one colored line on either side of the stage, use different colors. Additionally, change the starting x coordinate to 220, which will be the far right side. For this sprite, in the scripts tab, change the controls for upward and downward movement to ‘up’ and ‘down’ arrow keys. Next, right click on this sprite, and select duplicate. It is already beginning to look like the original ping pong game. Awesome, test the program to see if everything works as scripted, and it should.

This will prevent it from twisting when touching edges. Before you test it, click on the blue ‘i’ letter on the sprite profile, and choose – left right – rotation style. This will make the sprite start the game at this position on the stage. And for the ‘flag clicked’ block add the ‘go to x: y:’ block, and set -220 for x coordinates and 18 for y coordinates. Also, add the ‘if on edge’ bounce blocks both of them, to make sure the sprite does not leave the Scratch pong. Duplicate it, and add it for ‘a’ control, and change it to -30, to make it go the opposite way, downwards. Add the ‘change y by’ block from the Motion category. Now, when I press the ‘q’ key I want the sprite to change its ‘y’ position by 30 units. These two keys on the keyboard will be the main control. In the drop down menu choose letter ‘q’ and for the other one choose letter ‘a’. These blocks run the program when a certain condition becomes true.

Go to its scripts tab, and from the Events category add two ‘when space key pressed’ blocks, and one ‘when flag clicked’ block. Now it is time to program simple movement for this sprite.

Make sure that you set its central point in the middle. Next, create a new sprite by drawing a simple, thick black line onto the painting canvas. For my project, I have chosen a nice creamy, sand color. Next, click on the backdrop, click on costumes and set a nice background color by using the bucket tool. Lets st art by opening a new project, and delete the cat sprite right away. In this article I will show you how to create a very simple Scratch pong.
