    1 - Introduction

    In this lesson, we’re going to explore the magical world of fairy tales while learning how to use broadcasting to control when things happen in your Scratch projects.

    Instead of waiting for actions to occur, you’ll use broadcasts to trigger events, making your story flow smoothly from one part to the next. By the end of the lesson, you’ll have created a fairy tale scene where characters interact and the story progresses with perfect timing!

    2 - Create a new project

    Create a new project in Scratch.

    3 - Set the Scene

    Choose a fairy tale background from the backdrop library. It could be a castle, a magical forest, or a village. This will be the setting for your fairy tale adventure.

    4 - Add your Characters

    Add two or three characters that fit the fairy tale theme, such as a Princess, a Prince, and a Dragon. These will be the main characters in your story.


    Remember, you can change the size of sprites by changing the number in the 'Size' box underneath the Stage Area!

    5 - Hide the Dragon

    We'll need to hide the Dragon before we start the story. 

    Add the following code to the dragon before we can start coding the other characters.
