3 With this block your object listens for a specific broadcast message and then runs the script when the message is received. Useful to communicate between objects and tell them when to do something.

7 **Why send broadcast messages?**
8
9 With messages you can communicate and interact between different objects within a scene. It allows one object to send a message to all other objects, and the receiving objects can then react or respond to that message.
10
11 **How does it work?**
12
13 * //Sender object~:// The sender object starts the communication by using a //"Broadcast"// block. This block is used to send a message to all other objects in the scene (also the background).
14 * //Receiving object~:// The receiving object is the one that listens for and responds to messages. It uses the //"When you receive"// block to detect when a specific message is being received.
15 * //Message Handling~:// When the receiving object gets the message, it will execute all the blocks that are beneath the //"When you receive"// block. This allows you to define custom behavior or actions that occur when a particular message is received.
