You can already make sprites move and respond in Scratch. Today you will build a Paddle Ball game step by step.

Before you run anything new, think: if the ball's step size is stored in a variable called speed, what might happen when that value goes up after each hit?

You will predict, build, run, and fix as you go, and use mouse input so you can control the paddle.

Welcome to our exciting lesson on creating a Paddle Ball Game using Scratch! In this lesson, you will learn how to move sprites, use variables to control speed, change backdrops, and use sensing blocks. By the end of this lesson, you will have your very own Paddle Ball Game that you can play and share with your friends. Let's get started!

Create a new Scratch project and delete the cat sprite that's added by default.

Add the sprite called 'Paddle' from the sprite library.

Drag the paddle to near the bottom of the stage area (by holding down the left mouse button and moving your mouse). Make sure to leave some space between the bottom of the stage area and the paddle (this is important later on as we'll be putting something there).

Add the sprite called 'Soccer Ball' from the sprite library.
