This block will stay inactive until it receives the specified broadcast. Once it has been received, the script is executed. It can be started more than once.

Example: Broadcasting a message in Scratch

·         Add two sprites.

·         One sprite broadcasts a message to another, and another has to wait for a specific time.

·         After that time the other sprite will reply to the message.
