When I Receive ()

Category Event
Type Hat

The When I Receive () block is an Events block and a Hat block. Scripts that begin with this block will be invoked once the specified broadcast has been sent by a calling script.

If the same message is sent again while the script is still running, the script will restart without reaching the blocks at the end. Using the Broadcast () and Wait block can help to make a message script run over and over again.

Example Uses

Broadcasts are used to invoke scripts when certain evaluations are met; for scripts to activate once the broadcast is sent, those scripts must wear the When I Receive () block. Some common uses are:

when I receive [Failure v]
show
wait (3) secs
change [color v] effect by (25)
stop [all v]
  • Hiding select sprites when a certain condition is met under a particular evaluation
when I receive [broadcast v]
hide
  • When a scene must be set
when I receive [next background v]
next costume
  • Effective communication with scripts or sprites
when gf clicked
say [Hi!] for (1) secs
broadcast [communicate v]
when I receive [communicate v]
say [Hi!] for (1) secs
when I receive [run v]
. . .
broadcast [run v]
  • Winning a game
when I receive [win v]
say [You win!] for (2) secs
