Engine startup sounds

Ok, so I am editing the s550 mod by @Tsutarja495 so that the i4 and v6 have their engine sounds and startups restored from the previous version. When I first started, I didn't yet change the sfxBlend2D file, so they worked as long as the new s550.zip was accompanied by the old 1517mustang.zip file. However, it works independently now. My remaining problem is that the startup sounds only work if the lines shown below are in the mainengine sections of the engine jbeam and s550.zip is accompanied by 1517mustang.zip.

"starterSample" : "s42_starter",
"starterVolume" : 1.0,

I tried to make it work with the current version of BeamNG independently of the old file with this:

//starter motor
"starterSample":"s550:>art>sound>starter>s42",
"starterSampleExhaust":"s550:>art>sound>starter>s42.ogg",
"shutOffSampleEngine":"event:>Engine>Shutoff>i4_2001_eng",
"shutOffSampleExhaust":"event:>Engine>Shutoff>i4_2001_exh",
"starterVolume":7.00,
"starterVolumeExhaust":6.0,
"shutOffVolumeEngine":2.0,
"shutOffVolumeExhaust":1.36,
"starterThrottleKillTime":0.6,
"idleRPMStartRate":2,
"idleRPMStartCoef":1,

I think my problem is with the startersample file location. For reference, the sound files are in s550.zip/art/sound/starter. I have no idea how to set the file path for this in the jbeam. I have tried many different approaches to this but the startup sounds refuse to work, although the shutoff sounds located somewhere in the vanilla game work fine. Any help is appreciated.

 

this "starterSample":"s550:>art>sound>starter>s42",

should be "starterSample":"file:>art>sound>starter>s42",

if you are using an fmod event (not sure how to yet) use "event:->->->"

if you are using a file use "file:>->->"

i sometimes have problems when using custom sound with volume and stuff

 

Thanks for responding, but even with these changes, nothing happens. I've turned the volume for the starter motor up, but still nothing

//starter motor
"starterSample":"file:>art>sound>starter>s42.ogg",
"starterSampleExhaust":"file:>art>sound>starter>s42.ogg",
"shutOffSampleEngine":"event:>Engine>Shutoff>i4_2001_eng",
"shutOffSampleExhaust":"event:>Engine>Shutoff>i4_2001_exh",
"starterVolume":7.00,
"starterVolumeExhaust":6.0,
"shutOffVolumeEngine":2.0,
"shutOffVolumeExhaust":1.36,
"starterThrottleKillTime":0.6,
"idleRPMStartRate":2,
"idleRPMStartCoef":1,

 

It should be this "starterSample":"file:>art/sound/starter/s42.ogg",
or this "starterSample":"art/sound/starter/s42.ogg",
same for exhaust of course

 

That worked! Another problem has arisen, however. I can't implement any loop sounds and the car tries to loop the starter sound. Also, when I shut the car off, my custom shutoff sound loops infinitely. How do I fix these issues?

It's kinda complicated, currently the entire sound setup of the game is sort of fragmented all over the
place. The more you 'visit' the same files the more you're able to understand what is going on.
Sometimes rules (read code) are overridden by other rules in certain situations and then not and then
yes and so on.. So you must find the right file were 'AudioDefaultLoop3D' is to be replaced by 'AudioDefault3D'
for the sound in question. Hope this helps

 

Thanks for the help! However, in the mustang file, there does not appear to be any lua in relation to audio that I can change. Also, from the example in your post, the line including AudioDefault3D is in a .cs file, or specifically audioProfiles.cs. It mentions to copy and paste the profile into the engine jbeam, but how would I define it as the ignition loop? Sorry for my lack of understanding jbeams, kind of new to this lol.

 

OK I'm only responding vague because I often do several things at the same time, hope you don't mind.
If you found the profiles.cs you can start and try to change the profile of the sound in question from there. It's very likely that won't
work because I found out that in the core file of the turbocharger the blow-off sound is set to 'AudioDefaultLoop3D'. The turbo
has nothing to do with your starter of course but this points out that there are things not always set to right circumstances as I
mentioned in post#6 The devs are kind enough to let us mod as much as possible, even before everything got sorted out for
them, I guess Like if you visit the 'deprecated' wiki's sound section you will read that 'AudiDefaultLoop3D' is always to be set
as default when you don't know what to use else but the other profiles aren't even listed or explained, even 'defaultloop3D' isn't
really explained. Sound is very complicated to setup right, just as graphics are. I've been playing around with it and if you mess things
up just a little, even the whole game acts weird as a consequence. Sorry for drifting off.. What I mean is that LUA is always the
cause of looping or not looping the sounds, you just have to find in which file the setting is taking effect without overrides from
other file settings. Okay now I got this far that I better check if can find your problem right ? Hold on

Alright, so this line of text is to be found in the combustionEngine.lua (core file for engine)

starterSoundEngine = obj:createSFXSource2(device.jbeamData.starterSample or "event:>Engine>Starter>Old_V2", "AudioDefaultLoop3D", "", device.engineNodeID, 0),

This means that the games starter sound is looped for if the starter takes a longer time to start the
engine. Your sample is probably not made to be set as a loop but just to play once. Thus the
game goes looping your sample. Better is not to change the core file but to edit the sound sample
itself, so it becomes 'loopable'.

 

Again, thanks so much for helping! While your explanations are helping me to understand the arbitrary world of LUA in beamng, there simply does not seem to be any core engine file containing any lua in the s550 mod after searching through all possible directories. Also, I used audacity to convert sounds to .ogg and trim them so I have both an engine startup and rollover sound. Should I find the source code for the engine lua and modify it? Thanks

 

Well that's exactly what I explained in the previous post

You don't find the lua in your mod because every engine is using the core file combustionEngine.lua .
I showed you the text within :
starterSoundEngine = obj:createSFXSource2(device.jbeamData.starterSample or "event:>Engine>Starter>Old_V2", "AudioDefaultLoop3D", "", device.engineNodeID, 0),

Do you see the "AudioDefaultLoop3D" ? That's why your starter sample is looped. Good to see you're confident with Audacity because
you will have to 'rhythm out' your sample so it becomes perfectly 'loopable' . If you take the 'loop' out of the code above (so that means changing the core file) then all the other starter sounds will be messes up and if you update the game the core file will be replaced again
of course.

 

From what I am understanding, the game uses the same file for both the startup and turnover sounds and determines the part of the file that will be looped for the rollover? If so, that seems unnecessarily complex. Then how do I edit an ogg file for it to match the game's audio system? From what I can tell, the game's .bank files for audio are encrypted, so it is impossible to use them as an example.

 

Oh, ok. Thanks for clearing things up everyone.

 

I have to be fair and say there is a workaround for this but that gets rather complicated !
Nevertheless my prove is there , its to find in my new mod I'm working on, its waterproof and it doesn't hurt any other features
of the game BUT that takes some moderate programming skills. :/
