Microbit Paddle Ball

In this project we will use a Microbit to control the paddle in a Scratch Paddle Ball game. You will control the paddle by tilting the Microbit to the left and right.

1 - Create a new Scratch project

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

2 - Add the paddle sprite

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).

3 - Add the football sprite

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

4 - Position the ball

At the start of the game we want the ball to start at the top center of the screen. We can do this by setting the X and Y coordinates of the ball.

We want the ball to start at the top center of the screen which as at the location X:0 Y:170. To do this we add the following code to the ball sprite:

when green flag clicked go to x [0] y [170]

Once you've added this code and entered the correct X and Y coordinates, click on the green flag at the top right of your screen to run the code. Your ball should go to the top center of your screen.

5 - Make the ball bounce around

Now that we have the ball in the correct position for the start of the game, we want to make the ball start moving around the screen and bouncing of the edge of the screen when it touches it.

First we point the ball in a downwards diagonal direction and then we get it to continually move, if it touches the edge of the screen we want it to bounce. Add the following code underneath the go to x: 0 y: 170 block:

when green flag clicked go to x [0] y [170] // insert new code under here point in direction [120] forever move [10] steps if on edge bounce end

Run your code by clicking the green flag. The ball should start bouncing around the screen!
