Sprites Talking to Each Other: Broadcast Messages — ICT

Sprites Talking to Each Other: Broadcast Messages

1 of 4

For grown-ups

Companion summary

Imagine your code is a radio station, sending a signal that every listener tunes into at once. Games like Minecraft use broadcast-style messages so all players hear the same event at the same time. In Scratch, one broadcast can make a sprite dance, play a sound, and change the backdrop all together. When you finish, try sending two different broadcasts and see which one your sprites react to first.

Ready, Set, React!

Imagine you are in a relay race. You run your part, then you pass the baton to the next runner. The moment that runner feels the baton, they start moving. Your code can work the same way — one sprite can 'pass the baton' to another sprite so they know when to go. This passing of the signal is called a broadcast message.

💭 Think about this

Can you think of a real-life situation where one person sends a signal and a group of people all react at the same time? (Hint: think about a referee's whistle or a starting gun.)

How Broadcast Messages Work

When you code a project with more than one sprite, you sometimes need them to work as a team. A is a way for one sprite to shout 'Hey, it's your turn!' to the rest of the project. There are two blocks you need: 1. The uses the 'broadcast [message name]' block. When this block runs, it sends a named signal out to the whole project — like a whistle being blown. 2. The uses the 'when I receive [message name]' block at the top of its . Whenever it hears that signal, it starts running that script straight away. You can have as many sprites as you like all listening for the same message. When the message is broadcast, every sprite that has a matching 'when I receive' block will react at the same time. You choose the name of the message yourself. Clear names like 'game-start' or 'door-open' help you remember what each message is for.

Worked example

GOAL: When a cat sprite touches a star, a rocket sprite blasts off. Step 1 — Cat sprite script: 'when green flag clicked' 'forever' 'if touching [Star] then' 'broadcast [launch-rocket]' Step 2 — Rocket sprite script: 'when I receive [launch-rocket]' 'change y by 10' (repeated or inside a loop to keep moving up) When you run the project and the cat touches the star, it broadcasts 'launch-rocket'. The rocket sprite hears this message and immediately starts moving upward. The two sprites are now working as a team without the cat telling the rocket exactly what to do — it just sends the signal and the rocket decides its own action.

Try It Yourself

Try it yourself

Read each question carefully and choose the best answer.

1. What does a 'broadcast [message]' block do?

2. Which block does a receiver sprite need at the top of its script?

3. In a project, Sprite A broadcasts the message 'lights-on'. Sprite B and Sprite C both have 'when I receive [lights-on]' blocks. What happens?

4. A student wants a door sprite to open when a button sprite is clicked. Where should the 'broadcast [open-door]' block go?

5. Why is it a good idea to give broadcast messages clear names like 'game-over' instead of 'msg1'?

What Have You Learned?

Use 'broadcast [message]' in the sender sprite to send a signal.
Use 'when I receive [message]' in the receiver sprite to react to that signal.
Many sprites can all listen for the same message and react at the same time.

1. Look at this script for a trophy sprite: 'when I receive [player-wins]' 'show' What will make the trophy appear on the stage?

🌱 Reflect

Think about a mini game you would like to build. Can you describe one moment in that game where a broadcast message would be useful — what would send it, and what sprite would react?
