Hey computer scientists, welcome to CS First Storytelling.
Today, you will create a story using characterization.
In storytelling, characterization gives important detailsabout the personality, background and motivationsof a character to let the audienceget to know him or her better.
To give the audience more details about a character,authors use five main elements:dialogue, thoughts, actions,appearance and effect on others.
Check out how these elements are uses in these projects.
By adding details about what a character says and thinks,what he or she looks like andhow he or she interacts with others,authors reveal a character's personality.
This helps the audience feel more connectedwith both the character and the story.
To create your characterization story,you'll begin with a starter project.
This project has two main sprites,a narrator sprite that tells the storyand a main character sprite.
The narrator will talk to the audienceabout the main characters thoughtsand the main character will act out the storyby changing its actions and appearancedepending on what the narrator says.
In order for the main character to know and act outwhat the narrator is saying,you willneed to instruct the computer to broadcastor send the message that tellsthe other sprites to react to the narrator.
In the previous project you usedthe say block to create dialogue.
The say block lets the audience readwhat the sprite's say to each otherbut the sprites can't read what's in the say block.
To communicate, sprites need information broadcast to them.
When you receive the message from a weather reporterthat it might rain you react by packing your umbrella.
The broadcast block does the same thing.
It sends a message,and the part of the program that receives the message,then reacts in a specific way.
The starter project already containsthe dinosaur's reactions to messagesthat the narrator will broadcast.
You will choose when to broadcast them.
To get started, click on the starter project linkand sign in to Scratch.
Then click remix, then return to see us firstand watch the next video andlearn how to broadcast an action to your main character.
