lesson 23

What is the purpose of the broadcast block in Scratch?

• To stop the project

• To send a message to all sprites to trigger actions

• To change a sprite's size

• To receive a message to all sprites to trigger actions

How does the "when I receive broadcast" block work?

• t changes the costume of a sprite

• It triggers a script when a specific broadcast message is send

• It duplicates the sprite

• It triggers a script when a specific broadcast message is received

Which block would you use to send a message to all sprites in the project?

• 
• 
• 
• 

What happens if you broadcast a message that no sprite is listening for?

• • The project stops

• The broadcast will cause an error

• Nothing happens until a sprite has a "when I receive broadcast" block for that message

• • All sprites change their costumes

What is the importance of the broadcast block in Scratch?

• It allows sprites to communicate and trigger actions between different parts of the project

• It makes sprites move faster

• It automatically changes the background

• It stops the project from running

How can you use the broadcast block to start multiple actions at once?

• By sending multiple broadcasts

• By having multiple sprites with "when I receive broadcast" blocks

• By duplicating the script

• By setting a delay

Why might you use the "broadcast" block instead of using a "when green flag clicked" block for triggering events?

• To send a message to multiple sprites to perform actions at the same time

• To change the color of the sprite

• To adjust the volume of the sound

• To increase the size of the sprite

How can you organize your broadcasts to avoid confusion in a Scratch project?

• Only use one broadcast message for the entire project

• Use the same broadcast name for every event

• Broadcast messages in random order

• Name each broadcast message clearly and use them consistently

How can you make sure that a sprite only responds to specific broadcasts?

• 
• 
• 
• 

If a broadcast message is not being received as expected, what should you check?

• Ensure that the message name is correctly spelled and matches exactly in both the broadcast and the "when I receive" block

• Check the sprite's costume

• Verify the sprite's location on the stage

• 
  Ensure that the message name is wrong spelled and matches exactly in both the broadcast and the "when I receive" block
