<[message1 v] has been received?>

when I receive [start v]
repeat until <[start v] has been received?>
turn cw (45) degrees
wait (0.5) secs
turn ccw (90) degrees
wait (0.5) secs
end

1.1 “Broadcast received” boolean block
The block below would allow a project to detect when a broadcast is sent. But, there is a lot of ambiguity on how this would work. Would it return true if the broadcast was fired since the project was created, since the green flag was clicked, or since something else was broadcasted? The workaround is simple: use variables that change when a broadcast is received, then use the “equals” block.

However, the blocks “repeat until broadcast received” and “wait until broadcast received” are NOT rejected; you can discuss them on this post.

<[message v] received? :: events>

(if <> then () else ())

set [random variable v] to (if <mouse down?> then (1) else (2))

if <mouse down?> then 
set [random variable v] to [1]
else
set [random variable v] to [2]
end

looks like everything i suggest is rejected by the scratch team.
anyway, another suggestion is the

(if <> then () else ())

reporter. if the boolean is true, then the reporter output is the first input. if the boolean is not true, then the output is the second input.
this

set [random variable v] to (if <mouse down?> then (1) else (2))

instead of the workaround:

if <mouse down?> then 
set [random variable v] to [1]
else
set [random variable v] to [2]
end
