I want each backdrop to have a different ambient sound, and to repeat, but to stop and change to another sound when the backdrop changes. My character will move from one backdrop to the next.

here's my project for reference. Thank you for the help!

I have good news for you, there is such a block as

when backdrop switches to [ v]

And you can use it for your own purposes!

when backdrop switches to [backdrop1 v]
stop all sounds
repeat until <not <(backdrop [name v]::looks) = [backdrop1]>>
play sound [backdrop1 ambient v] until done
end

when backdrop switches to [backdrop2 v]
stop all sounds
repeat until <not <(backdrop [name v]::looks) = [backdrop2]>>
play sound [backdrop2 ambient v] until done
end

(this code in backdrop)

I've tried this same thing, but it doesn't seem to work. The sound won't start when the background changes.

forever
if <(backdrop #) = [1]> then
stop all sounds
repeat until <not <(backdrop #) =[1]>>
play sound [ v] until done
end
end
... // duplicate however many times you need
end

Generally, I find that these hat blocks seem to sometimes not work for whatever reason. I always use the forever if workarounds.

when [ v] key pressed
when this sprite clicked
when backdrop switches to [ v]
when [ v] > (10)

This works better, but the sounds still won't stop when the backdrop changes. Is there a way to stop them immediately without using the Stop All sounds block? There are other sounds I don't want to stop when backdrops are switched.

I think you can do something like the below to stop a sound and start a new one. If a script is running under when I receive when it is broadcasted, the script will stop and restart. I think the sound will stop with the script, but I could be wrong.

when I receive [Restart sound v]
forever
if <(backdrop [number v]::looks) = [1]> then
play sound [backdrop1 v] until done
else
if <(backdrop [number v]::looks) = [2]> then
play sound [backdrop2 v] until done
else
...
end
end
end

I'm afraid not.

Yes, there is a way, move all sounds into a new sprite, when you want to play a specific sound create a clone of such sprite and make it play that sound, to stop the sound you just delete the clone.

Agreed. Even with the when key pressed hat blocks, they almost never work correctly.

This works if you only have one sound to stop, but it has the same problems as before when switching from one sound to another. Thank you for the idea anyway though

I´d say that you need to practice scratching a bit more….

Im trying but i'm just not sure it will work for my project.

It is OK, do you speak Spanish fluently? I am askig because it is too much stuff to explain and i have very little skill writing and speaking English, and dealing with clones require full understanding cause some times it is a tricki thing. Just wait to other scratcher able to explain. You keep scratching. Greetings.

make a sprite for the sound and insert this loop:

forever
if <(backdrop name) = [your backdrop name... duh]> then 
set volume to (100) %
else
set volume to (0) %
end
end

and then just put this in

forever
play sound [sound v] until done
end

however the sound will not restart and continues playing after muted.

put this code in to where you want

switch backdrop to [backdropname]

then put this one in too.

when backdrop switches to [backdropname v]
repeat until <not <(backdrop #) = [1]>>
play sound [yoursound v] until done
end

if the “when backdrop switches to” hat block does'nt work, try to replace the

 when backdrop switches to [backdropname v] 

hat block with the

when green flag clicked

hat block.

Please try not to necropost. The topic is over a year old so is presumably resolved.
