What do these blocks do?

when I receive [ v]
broadcast [ v]
broadcast [ v] and wait

These blocks are basically a way for sprites to communicate. So, if you put this script into sprite 1:

when green flag clicked 
wait (3) secs
broadcast [ v]

and this in sprite 2:

when I receive [ v]
say [Hello!]

Then, sprite 2 will say hello after 3 secs

The broadcast blocks make things so much easier within your projects! You can use them among many messy lines of coding where you probably won't want to use the “wait (#) seconds” in order to make your sprites act at the same time during your game, animation, etc. @mitdk explained it amazingly.

Oohh, now I get it

broadcast [broadcast1 v] and wait

This block sends a broadcast similar to the other blocks, but the script doesn't continue until all of the blocks under a

when I receive [broadcast1 v]

block have finished.

So if you did this:

when I receive [broadcast1 v]
wait (3) secs

when green flag clicked
broadcast [broadcast1 v] and wait
say [Hello!]

The sprite would say “Hello!” after 3 seconds.
