Hey computer scientists –welcome to Day 5 of CS First Storytelling.
Today you will create a story using characterization. In storytelling, “characterization” givesimportant details about the personality, background, and motivations of a character to let theaudience get to know him or her better. To give the audience more details about acharacter, authors use 5 main elements: dialogue, thoughts, actions, appearance, and effecton others. Check out how these elements are used in projects created by other CS Firststudents. By adding details about what a character saysand thinks, what he or she looks like, and how he or she interacts with others, authorsreveal a character’s personality. This helps the audience feel more connected with boththe character and the story.
To create your characterization story, you’ll begin with a starter project. This projecthas two main sprites - a narrator sprite that tells the story and a main character sprite.
The narrator will tell the story by talking about the main character's feelings or actions.Themain character will act out the story by changing its actions and appearance, depending on whatthe narrator says. For the main character to know what the narrator is saying so itcan act out the story, you need to instruct the computer to “broadcast,” or send amessage, that tells the main character sprite to react to the narrator.
In a previous project, you used the “say” block to create dialogue. The “say” blocklets the audience read what sprites say to each other. But, the sprites can’t readwhat’s in the “say” block. To communicate, sprites need information broadcast to them.
When you receive the message from a weather reporter that it might rain, you react bypacking your umbrella. The “broadcast” block does the same thing--it sends a messagethat makes the part of the program that receives the message react in a specific way.
The starter project already contains the main character’s reactions to messages that thenarrator will broadcast. You will choose when to broadcast them.
To get started: Choose one of the starter projects,click “remix,” and sign in to Scratch. Then, return to CS First to watch the nextvideo and learn how to broadcast an action to your main character.
