How to make OrbiterSound load an different sound file for RCS

[Orbiter Fan]

Hello.

Does someone know how to make OrbiterSound load an different sound file for the RCS? I want to
know this since I don't really like hearing the RCS thruster sound when I make my MER move. I
want to have an more appropriate sound file for that. Any help is appriciated!

It's only for you or to be installed on user's computer ?

If it's only for you you can replace "attfire.wav" and "attsustain.wav"
in the folder "sound/vessel" by your how sound.

If it's for other I suggest you program this yourself with two
custom sound (or only one)

That's easy if you write the module (but impossible with
vinka dll)

Let me know

Could you please show me how to accomplish this?

[DanSteph]

no problem here is how OrbiterSound do it:
(it's a bit more complicated in fact but it will be too long
 and you will not understand the point, so this is a basic custom code specially for you.
Tune it until satisfaction)

// PUT THIS BELOW IN .H FILE
-------------------------------------
#define RCS 50

// PUT THIS BELOW IN OVCINIT
---------------------------------------
ConnectToOrbiterSoundDLL();
RequestLoadVesselWave(RCS,"Sound\\yourfolder\\rcs.wav");
SoundOptionOnOff(PLAYATTITUDETHRUST,FALSE);


// PUT THIS BELOW IN OVCTIMESTEP
//---------------------------------------------
// here we record a value to see if one thruster is active
double ThrusterActive = GetThrusterGroupLevel(THGROUP_ATT_PITCHUP) +
GetThrusterGroupLevel(THGROUP_ATT_PITCHDOWN) +
GetThrusterGroupLevel(THGROUP_ATT_YAWLEFT) +
GetThrusterGroupLevel(THGROUP_ATT_YAWRIGHT) +
GetThrusterGroupLevel(THGROUP_ATT_BANKLEFT) +
GetThrusterGroupLevel(THGROUP_ATT_BANKRIGHT) +
GetThrusterGroupLevel(THGROUP_ATT_RIGHT) +
GetThrusterGroupLevel(THGROUP_ATT_LEFT) +
GetThrusterGroupLevel(THGROUP_ATT_UP) +
GetThrusterGroupLevel(THGROUP_ATT_DOWN) +
GetThrusterGroupLevel(THGROUP_ATT_FORWARD) +
GetThrusterGroupLevel(THGROUP_ATT_BACK);
if(ThrusterActive>1.0f)
ThrusterActive=1.0f;

// execute only if a thruster is active
if(ThrusterActive>0.0f)
{
// we calculate the volume at wich it must be played
double volume=110+(145*ThrusterActive);
PlayVesselWave(RCS,LOOP,Volume);   // play the sound
}
else if(IsPlayingVesselWave(RCS)
{
// else shut down the sound if it's playing
StopVesselWave(RCS);
}

That's it, take care that for now the option will shut down the rcs of all the vessel
in the scenario, I'll rewrite OrbiterSound so each vessel will be independent
but later.

Thanks for the code Dan. But when I compile I get these errors:

}
else if(IsPlayingVesselWave(RCS)
{
// else shut down the sound if it's playing
StopVesselWave(RCS);
}

   ((NASA_MER*)vessel)->Timestep (simt);
}

Do you see any errors?

[DanSteph]

Yes , you are not in your vessel's class.

So either you deplace your whole code to your CLASS timestep
(Timestep (simt)  (search about : "TimeStep") you must find a
NASA_MER::TimeStep(double simt) function.

Either you add the vessel pointer to each vessel function
(ie: vessel->GetThrusterGroupLevel(THGROUP_ATT_PITCHUP) +
vessel->GetThrusterGroupLevel(THGROUP_ATT_PITCHDOWN) + )


But the first methode is the right one.

I can't get it to compile. Dan, it would make me very happy if you could modify the source code
