For some reason, the [ljass]SetSoundPitch()[/ljass] native seems to be bugged.

Let's look at some code here:
JASS:
    local sound s1 = CreateSound("war3mapImported\\PiccoloA5.mp3", false, false, false, 10, 10, "")
    call StartSound(s1)
    call SetSoundPitch(s1, 1)
    call TriggerSleepAction(3)
    call SetSoundPitch(s1, 1.3)
    call StartSound(s1)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1.301)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1.302)

The first sound has the correct pitch of 1.
The second sound has the correct pitch of 1.3
The third sound has a pitch of 1.3^2
The fourth sound has a pitch of 1.3^2

JASS:
local sound s1 = CreateSound("war3mapImported\\PiccoloA5.mp3", false, false, false, 10, 10, "")
call StartSound(s1)
call SetSoundPitch(s1, 1)
call TriggerSleepAction(3)
call SetSoundPitch(s1, 1.3)
call StartSound(s1)
call TriggerSleepAction(3)
call StartSound(s1)
call SetSoundPitch(s1, 1.3)
call TriggerSleepAction(3)
call StartSound(s1)
call SetSoundPitch(s1, 1.302)

First Sound: 1.0
Second Sound: 1.3
Third Sound: 1.3
Fourth Sound: 1.3^2

Now that this wasn't weird enough, there is more:
JASS:
    local sound s1 = CreateSound("war3mapImported\\PiccoloA5.mp3", false, false, false, 10, 10, "")
    call StartSound(s1)
    call SetSoundPitch(s1, 1)
    call TriggerSleepAction(3)
    call SetSoundPitch(s1, 1.3)
    call StartSound(s1)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1.3)

Real pitch values:
First Sound: Pitch 1
Second Sound: Pitch 1.3
Third Sound: Pitch 1.3 (??)
Fourth Sound: Pitch 1.3 (????)

Same goes for
JASS:
    local sound s1 = CreateSound("war3mapImported\\PiccoloA5.mp3", false, false, false, 10, 10, "")
    call StartSound(s1)
    call SetSoundPitch(s1, 1)
    call TriggerSleepAction(3)
    call SetSoundPitch(s1, 1.3)
    call StartSound(s1)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1.001)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1.301)

Real pitches:
1.0
1.3
1.3 (???)
1.3

And now to make it even more weird:
JASS:
    local sound s1 = CreateSound("war3mapImported\\PiccoloA5.mp3", false, false, false, 10, 10, "")
    call StartSound(s1)
    call SetSoundPitch(s1, 1)
    call TriggerSleepAction(3)
    call SetSoundPitch(s1, 1.3)
    call StartSound(s1)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1.301)
    call TriggerSleepAction(3)
    call StartSound(s1)
    call SetSoundPitch(s1, 1)

1.0
1.3
1.3^2
1.3 (?????)

I give up ... I can not find ANY logical pattern here. Someone please help; am I missing something? If someone can give me a reason for this weird behaviour, please help!
I want to write a SetSoundPitchEx function, but without a logical pattern, there's nothing I can do about it.

PS: Changing the Length of the TriggerSleepAction or Starting the Sound after or before setting the sound pitch does not make any difference.

i'm pretty sure you should have posted this in the jass section.

EDIT: just an idea since i don't have the slightest clue. but could it be possible that it can't handle floats with more than 2 decimal places? since most of the abnormal results seem to be related to them.

Well, the native allows for very precise digits. Even something like Pitch 1.059465 is possible (In fact, this number is the frequency factor that pushes the sound a half note higher. 1.059465^12 = 2, which is a full octave. I am currently writing a GuitarTab interpreter system for WC3, so this is crucial.

I will post it again in the JASS section, Thanks.

    Crazy how much 3d printing has come in the last few years. Sad that it's not as easily modifiable though
  • Varine Varine:
    I bought an Ender 3 during the pandemic and tinkered with it all the time. Just bought a Sovol, not as easy. I'm trying to make it use a different nozzle because I have a fuck ton of Volcanos, and they use what is basically a modified volcano that is just a smidge longer, and almost every part on this thing needs to be redone to make it work
  • Varine Varine:
    Luckily I have a 3d printer for that, I guess. But it's ridiculous. The regular volcanos are 21mm, these Sovol versions are about 23.5mm
  • Varine Varine:
    So, 2.5mm longer. But the thing that measures the bed is about 1.5mm above the nozzle, so if I swap it with a volcano then I'm 1mm behind it. So cool, new bracket to swap that, but THEN the fan shroud to direct air at the part is ALSO going to be .5mm to low, and so I need to redo that, but by doing that it is a little bit off where it should be blowing and it's throwing it at the heating block instead of the part, and fuck man
  • Varine Varine:
    I didn't realize they designed this entire thing to NOT be modded. I would have just got a fucking Bambu if I knew that, the whole point was I could fuck with this. And no one else makes shit for Sovol so I have to go through them, and they have... interesting pricing models. So I have a new extruder altogether that I'm taking apart and going to just design a whole new one to use my nozzles. Dumb design.
  • Varine Varine:
    Can't just buy a new heatblock, you need to get a whole hotend - so block, heater cartridge, thermistor, heatbreak, and nozzle. And they put this fucking paste in there so I can't take the thermistor or cartridge out with any ease, that's 30 dollars. Or you can get the whole extrudor with the direct driver AND that heatblock for like 50, but you still can't get any of it to come apart
  • Varine Varine:
    Partsbuilt has individual parts I found but they're expensive. I think I can get bits swapped around and make this work with generic shit though
