Hey there! Today, we’re going to learn how to create a fun two-player Pong game using Scratch. By the end of this guide, you’ll have your very own game to play with a friend. Let’s dive in!
First, let’s talk about what we already have. Imagine a simple Pong game where a ball bounces around the screen. It changes direction when it hits a paddle, which you control with your mouse. Now, we’re going to make this game even more exciting by adding a second player!
To make it a two-player game, we need to add another paddle. We’ll call them Paddle One and Paddle Two. You can rotate them to face the right direction by clicking on the direction setting in Scratch.
Instead of using the mouse, let’s control Paddle One with the up and down arrow keys. For Paddle Two, we’ll use the W and S keys. Here’s how to set it up:
1. Use the “change Y by 10” block from the motion category to move Paddle One up when the up arrow key is pressed.
2. Put this block inside a forever loop so it keeps checking if the key is pressed.
3. Duplicate the code and change it to “change Y by -10” for moving Paddle One down with the down arrow key.
1. Copy the code from Paddle One.
2. Change it so that Paddle Two moves up with the W key and down with the S key.
Now both paddles can move independently, making the game more interactive!
Let’s add a scoring system to make the game competitive. We’ll create two variables: one for Player One’s score and another for Player Two’s score.
1. Add two line sprites on either side of the screen to detect when the ball goes past a paddle. Color them differently for clarity, like blue, and name them Line One and Line Two.
2. If the ball touches Line Two, Player One earns a point. Use the ball sprite’s code to check for this collision and increase Player One’s score by one.
3. Add a short wait time after scoring to prevent multiple points from being added for a single hit.
4. Duplicate this setup for Line One so that Player Two earns a point when the ball touches it.
Finally, let’s make sure the scores reset to zero when the game starts. Do this by setting both Player One’s and Player Two’s scores to zero when the green flag is clicked.
And there you have it! You’ve created a two-player Pong game in Scratch. Now you can challenge a friend and see who scores the most points. Happy coding!
Hey there! Let’s get creative by designing your own paddles for the Pong game. Use Scratch’s costume editor to draw unique paddles for both players. Think about colors and shapes that will make your game stand out. Once you’re done, test them in the game to see how they look in action!
Now it’s time to experiment with the ball’s movement. Try changing the speed or direction of the ball to make the game more challenging. Use Scratch blocks to adjust the ball’s speed and see how it affects gameplay. Can you make the ball move faster after each point?
Let’s add some flair to your game by designing a scoreboard. Use Scratch’s text and drawing tools to create a scoreboard that displays the players’ scores. Make sure it’s easy to read and updates correctly when a player scores a point. How can you make it look exciting?
Spice up your game by adding power-ups! Create a new sprite that appears randomly on the screen. When a paddle touches it, something special happens, like increasing the paddle size or slowing down the ball. Use Scratch blocks to code these effects and surprise your players!
Invite your classmates to a Pong tournament! Set up a bracket and see who can score the most points in your game. Keep track of scores and declare a winner at the end. This is a great way to share your creation and have fun with friends. Who will be the Pong champion?
Sure! Here’s a sanitized version of the YouTube transcript:

Hi everyone, it’s Zia here. Today I wanted to show you how to make a two-player Pong game in Scratch. By the end of this video, you’ll be able to create your own game like this. Let’s get started!
First, let’s say that I have made this Pong game and I want to turn it into a two-player game. I recommend watching my previous video on how to make a Pong game in Scratch, as it will help you understand what all of this code does.
Basically, we have a ball sprite that can move around randomly, and if it runs into the paddle sprite, it will turn around and bounce in the other direction. You’ll see it bounces off the paddle, and the paddle moves when you move the mouse.
To make it a two-player game, the first thing we can do is add another paddle sprite. I’ll call them Paddle One and Paddle Two and rotate them so they are facing the right direction. You can do that by clicking on the direction setting and rotating the sprite.
Now, instead of making Paddle One move with the mouse, let’s change it so that Player One’s paddle moves with the up and down arrow keys, and Player Two’s paddle moves with the W and S keys.
To make Paddle One move up and down with the arrow keys, we can use the “change Y by 10” block from the motion category. We’ll set it up so that when the up arrow key is pressed, it changes Y by 10. We need to put a forever loop around this code so it continuously checks if the up arrow key is pressed.
Next, we can duplicate this code to allow Paddle One to move down when the down arrow key is pressed. We just need to change it to “change Y by -10” for the downward movement.
Now, let’s give Paddle Two the same code, but we’ll modify it so that it moves up with the W key and down with the S key.
Now both paddles can move independently!
Next, I’ll show you how to add points to the game. We need to create two variables to keep track of Player One’s score and Player Two’s score.
To detect if the ball has hit the wall on either side, we can add two line sprites on either side of the screen. I’ll color one blue for clarity and name them Line One and Line Two.
Now, if the ball runs into Line Two, Player One gets a point. We’ll set this up in the ball sprite’s code, checking if it touches Line Two and changing Player One’s score by one. We’ll put this inside a forever loop to continuously check for collisions.
To prevent the score from increasing multiple times for a single hit, we can add a wait time after changing the score. We’ll duplicate this code for Line One, so if the ball touches it, Player Two gets a point.
Finally, we need to reset the scores to zero when the game starts. We can do this by setting both Player One’s and Player Two’s scores to zero when the green flag is clicked.
And that’s it! The link to this project will be in the description, so you can remix it. Thanks for watching, and happy coding!

This version maintains the instructional content while removing any informal language or unnecessary filler.
Scratch – A visual programming language that lets you create games and animations by snapping together code blocks. – In Scratch, I made a cat dance by connecting the motion blocks together.
Game – A fun activity or challenge that you can play on a computer, often created using code. – We designed a simple game in class where you have to catch falling apples.
Paddle – A flat object in a computer game that you can move to hit or catch something, like in a ping-pong game. – I used the arrow keys to move the paddle and bounce the ball back in the game.
Player – A person or character that participates in a computer game. – Each player in the game has three lives to complete the level.
Score – The number of points a player earns in a game by completing tasks or challenges. – My score increased every time I collected a coin in the game.
Control – The ability to direct or manage the actions of a game or program using input devices like a keyboard or mouse. – I used the spacebar to control the jump action of my character.
Motion – The movement of objects or characters in a game, often controlled by code. – I added motion to the sprite so it could glide across the screen.
Arrow – A symbol or key on the keyboard used to indicate direction, often used to move characters in a game. – Press the right arrow to move your character forward in the game.
Interactive – Allowing a user to engage with a program or game by making choices or controlling actions. – The interactive story let us choose different paths for the characters.
Coding – The process of writing instructions for a computer to create programs, games, or websites. – We learned the basics of coding by creating a simple animation in class.
