The Broadcast command is like a director with a megaphone yelling "Action" which starts the actors to perform whatever was scripted for them to do or say. The BROADCAST block is an Event block that sends a message throughout the whole Scratch program. Any scripts in any sprites that are hatted with the WHEN I RECIEVE block will activate. Broadcasts are a good way to have sprites and scripts communicate. If a script must be activated without a user prompt and after the project has started, there is only one way — broadcasts.
