Should a when () costume number = () exist? This block is very helpful for using the broadcast unnecessarily.
With this block we can be more organized and not repeat pieces of scripts unnecessarily.
Without this block, scripts will look like this:

when green flag clicked
say [you want to race?] for (2) secs
say [ready] for (0.1) secs
say [set] for (0.1) secs
say [go] for (0.1) secs
switch costume to [run v]
broadcast [I'm using my car! v]

when I receive [I'm using my car! v]
if <winner!> then
say [I won!] for (2) secs
end

See that piece that I was referring to?

switch costume to [run v]
broadcast [I'm using my car! v]

We are repeating this piece every time we need to.


This is why we need this block:

when green flag clicked
say [you want to race?] for (2) secs
say [ready] for (0.1) secs
say [set] for (0.1) secs
say [go] for (0.1) secs
switch costume to [run v]


when [racer v] costume number = (2) :: custom hat block
if <winner!> then
say [I won!] for (2) secs
end

So what I'm seeing is, you're waiting until the car's costume number is 2, right? If so, what's wrong with using this code?

wait until <(costume #) = [2]>

Or this code, if the sprite is different:

forever
set [racer costume v] to (costume #)
end

wait until <(racer costume) = [2]>

i meant the message hat block.

Oh, okay then. I would still use the code I mentioned, but otherwise this would be a good addition.

It would be better to implement this as

instead, alongside


Either way, this is a duplicate, but the former could be workaroundable:
