Watch the Movie
Can you figure out how to make a vertical pong game like the one below? The paddle moves up and down (only), following the mouse. The ball bounces off the paddle and 3 walls, but when it hits the right-hand wall it stops — and you lose!
Make sure you’ve done the basics
Before you begin this project…
You should have previously created a regular Pong game, where the paddle moves from side-to-side (instead of up-and-down).
Open the regular Pong game now. Pull down the File menu and select Save As to make a copy. Type a different name (like “vertical pong”) for your new project and click OK.
In your new project, edit the Stage Background so that it resembles the one in the movie, with a vertical stripe of a different color at the right-hand side.
Step 2. Make the paddle move vertically
In vertical pong, the paddle moves up-and-down instead of left-and-right.
You’ll need to change the costume for your previous paddle (but don’t erase the scripts or delete the paddle sprite!). To do so, go to the Costumes tab for your paddle. Click Edit. Clear the drawing screen and then draw a vertical (up-and-down) paddle. Click OK to save your new paddle.
Now you’ll need to change your paddle script…
* First, change the commands so that paddle starts the game at the right-hand side. How?
* Then, change just one or two commands (puzzle pieces) to make the paddle move vertically. How?
Step 3. Make the ball bounce off the paddle
Finally, you need to make a small change in the ball script to make the ball bounce properly off the vertical paddle. What is it?
Hint! The change affects the direction of the ball!
