The When I Receive () block is a Control block and a Hat block. Scripts that wear this block will activate once the specified broadcast has been sent.
Broadcasts are used to activate scripts at certain times - for scripts to activate once the broadcast is sent, those scripts must wear the When I Receive () block. Some common uses are:
