Oh boy howdy I sure hope I started this thread in the right category.

My brother and I are making a real life-ish game with the help of Scratch for Halloween. Basically we're recreating a few parts of sister location, specifically Bellora's room. Feel free to cringe at us.

I tried to find a video example but I was afraid to link one because of bad words/scary stuff in the video, and I kind of don't want to be banned from Scratch. So hopefully you've seen/played the level I'm referring to.

We need to set up a microphone in a hallway, and the more sound that is detected/the louder the sound that is detected, a variable number will get higher. Not sure how else to explain it, but it would start at 0, and someone yelling could bump the number up to 90 something, maybe talking would set it to 50, etc. (I'm making up these numbers as I go.) Ideally the number wouldn't tick back down, so if it was at 50 it'd stay at 50 until it went up.

We'd have a music track in the background, and the variable would change the volume of the song. It'll play louder if the background noise of the room is louder.

So we ran into a few problems when trying to do this.

1. There's no way to detect sound in a Scratch project? I've been on Scratch for many-a many-a years now, and I swear I remember that being a feature. Mind you I did take a five month break, but I REMEMBER. Is there some kind of mod for this?

2. We can't have the soundtrack pick up in the microphone and change the volume level. This is probably an easy fix, I'm just lazy.

If there isn't a mod for this, what other programs can I use? Sadly I am not a very intelligent person and Scratch is the extent of my coding ability, so it's gotta be something I can learn fast.

Thanks for any help. Stay spooky my dudes.

There is indeed a block for that:

I believe it reports from 0 to 100. (edit: or -1 for no microphone.)

No easy fix for that I'm afraid! You'll just have to hope it doesn't pick it up :-)

Oh. Whoops. I saw that but thought it was something else. Maybe if it had been named “microphone volume” or something I would've found it, haha. Thanks.

Hmm… Okay. I'll figure something out. I'm just worried about feedback is all, but I've got a pretty decent mic so it might not be a problem.

Sounds* like an interesting project! I've thrown together a bit of code that should do what you're looking for:

when green flag clicked
set [music vol v] to [0]
forever 
  change [music vol v] by ((music vol) * (-.005))
  if <(music vol) < (loudness)> then 
    set [music vol v] to (loudness)
  end
  set volume to ((10) + ((music vol) * (0.9))) %
end

when green flag clicked
forever 
  play sound [scary music v] until done
end

The volume of your music will fluctuate between 10% and 100% depending on the volume of the room. Try it out, and if you need any changes or want me to explain the code, just let me know.

What's Scratch for Halloween and who is Bellora?

Oh no, Scratch for Halloween isn't a thing hehe. I'm making something for Halloween for me and some friends, with the help of Scratch. Hope that makes sense.

Bellora is a character from Sister Location. I wish I could tell you more but I'm not that far in the game yet and really don't know much else, other that when you're in her room you should probably be quiet. >-< Scary video game.

Use a microphone with a long cable and keep it far away from the speakers

If I'm understanding this correctly

$(".box-head")[0].textContent = "committing AT crimes since $whenever"

Oh, all right.

I still don't get how to detect sound in a program. Please Help.

This is the sound detection block.

Someone has already said that and you are aware this post is from 4 years ago?

It is very easy to make a sound detector. I made one in this project, https://scratch.mit.edu/projects/432293152/ It is very simple. Here is the code:

when green flag clicked
go to x: (-145) y: (-92)
set [ghost] effect to (100)
show
clear
set pen size to (4)
set pen color to [#7FFF00]
forever
pen down
change x by (2)
set y to (loudness)
pen up
if <touching [edge] ?> then
clear
go to x: (-145) y: (-92)
pen down
change x by (2)
set y to (loudness)
pen up
end
end

I hope this helped you!

Thanks for that solution… But… The first post asking for help is from 4 years ago.

The volume of your music will fluctuate between 10% and 100% depending on the volume of the room. Try it out, and if you need any changes or want me to explain the code, just let me know.

Cool idea, I think I`ll try it!

No he means to detect the loudness of the sound playing in the project

No, that's what they meant, and this has been answered a long time ago so don't necropost:
