No need for it to be a snowflake, it could snow scratch cats!

is there a workaround for this:

What do you want this block to do to what?

If you are talking about setting the speed of the sprite, this may help:

set speed to (...):: #7238a8

define set speed to (speed)
forever
move (speed) steps
end

Can't you see that it's a sound block?

The message above may contain wrong information, rude remarks, or something embarrassing to my current self. In this case, please ignore it and remember that I likely wrote it back when I didn't know what “respect” truly meant. I really hate thinking about it again.

No . . . It's not that obvious. Speed doesn't usually mean speed of sound, and please don't be rude.

(volume of music)

that would be:

(volume)

I think

otherwise, the

block is the input volume (mic)

I made it a sound block for a reason, its supposed to be the speed of the sound without the pitch changing

for me the sprites just stay floating at the top of the screen

That would be complicated, though.

i don't think you can change the speed of a sound without the pitch changing. i think thats just how it works. i'm not sure though.

Yes, but it depends on what type of block you're using. If you have a project with 1000
wait (1) secs
blocks, then it'll take up way less RAM than this:
when green flag clicked
create clone of [myself v]

when I start as a clone
create clone of [myself v]
delete this clone
That actually crashes the editor, so less blocks don't always mean it's faster, it depends on the type of blocks you're using.
It doesn't crash the editor

Actually, it does. https://scratch.mit.edu/projects/161875695/

If you're seeing this signature, that means I've come out of my social anxiety hole.

Also, I edit the Scratch Wiki. Check it out sometime it's cool I guess.

Oh, I just thought about this:

when [timer v] > (0)
if <...> then
...
wait until <not <...>>
end

I got a lot of compliments on my last signature, and I think that's kind of strange. I wrote it when I was 12 and it wasn't very good. I acted like PS4 controllers were the epitome of human technology, for God's sake! I tried too hard to be philosophical, or maybe I tried too hard to be funny, or maybe it was something else. But that signature was bad. It wasn't good. It might be strange for some of you to hear this, seeing as this site is full of kids, but 12-year-old me was practically a baby. I think that's something you realise when you grow up. That you're always better than you were last year. I was looking through old Skype messages between me and a friend of mine from when we were 12, and as I read them, I couldn't stop thinking, “Woah. I was the worst.” It's important to know that you're always the worst. I can almost guarantee that future you is thinking negatively of you right now, just as future me is thinking negatively of me. It's important not to let that get to you. Remember to stay in the present. Tomorrow hates you, but it can't hurt you because you'll never get to tomorrow. When I was 10 or 11, I remember seeing the world very cynically. I thought that human life was inherently selfish, and that we were only put on this planet to destroy it. I'm so glad 10 or 11 year old me is gone, because 17 year old me would NOT get along with that kid.

This reminds me of a workaround to linearly control the playback speed for sounds, so here's mine (with pitch change)

My workaround with explanation:
Every 120 (twelve semitones or one octave) units up the pitch/speed increases 2*
(This is a exponential rate of change, so our answer is likely going to have a log function if we want to use this function in a “linear” way)

x = Scratch Input
S = Speed that we want to control (Scratch's output) (e.g.: 2 times speed)

1] S = 2^(x/120) || transcribe our formula, this is how the normal speed is calculated.
2] log₂(S) = log₂(2^x/120) || We get the log base 2 to cancel out the 2^n and bring n down.
3] log₂(S) = x/120 || Now get log base 2 to cancel the 2^n.
4] 120 * log₂(S) = x || Divide by 120 and we're done isolating x! (But now we have to write log₂ in terms of log or ln)
5] 120 * log(S)/log(2) = x || Using change of base rule we have completed the final step.

Now write it in Scratch blocks

set [speed v] effect to ((120) * (([log v] of (Rate)) / ([log v] of (2)))):: sound
now we can evaluate it and rewrite:: control
set [speed v] effect to ((398.6313713864836)*([log v] of (Rate))):: sound

You can't put reporter variables inside if blocks like that. You have to use [] = true
