Wrong sounds after calling oapiSetFocusObject()

[movieman]

I seem to have found a problem with Orbitersound 3.0. I have a LEM and CSM and in the LEM I use the EVA switch to create an
astronaut. The LEM calls oapiSetFocusObject() to change focus to the astronaut, which then loads some sounds and plays them.

The problem is, I either get LEM sounds played, or nothing at all. However, if I manually switch back to the LEM and then to
the astronaut again, the sounds play properly.

Is this something that can be fixed, or is there some other way I can do this to work around the problem?

Can you see the OrbiterSound_log.txt ? try to see it just after switching all info are here...

Perhaps you might give somes timestep after the creation of the eva suit before
giving it the focus ? OrbiterSound doesn't load the sound immediatelly when
they are requested if you give the focus immediatelly it might be the problem.

pseudo code:

Code: [Select]

CreateModel
FocusChangeRequested=10;

void timestep(dt...)
{
      // give the focus to model
      if(FocusChangeRequested>1)
      {
            // now changing the focus
            if(FocusChangeRequested==1)
                oapiSetFocus();

            FocusChangeRequested--;
     }
}

Perhaps trying different value for "FocusChangeRequested"

I tried adding a 500 timestep wait before it tries to play any sounds and that made no difference. The only way I can get
them to play is to use F3 to switch focus to the LEM and back before it starts playing.

I can try changing the LEM code so it waits a few timesteps before switching, and see if that helps.

Ok, I added a delay before switching focus from the LEM, and a delay in the astronaut DLL before playing the 'one small step'
sound, and that seems to work now.

I still don't seem to have music in the external view though...

Have you set soundconfig Mp3 parameter to "play in space?"

[movieman]

I get music in space for the other vessels, just not the astronaut: though I noticed last night that it does seem to
disappear at times for the CSM too.

[DanSteph]

the code that switch Mp3 on/off is called each timestep, if the setting is in "external space only"
it then look at your focus vessel's pressure and then call the oapiCameraInternal() function.

I don't see any reason it would not work unless oapiCameraInternal() don't return right value
after having granted and set focus to your vessel (or focus pressure is wrong ?)

Anyway that's strange if work flawlessly for DGIII eva the only difference is that I don't give
focus , perhaps odd things happen here ?

What are you doing exactly when it don't work ? Does the OrbiterSound
log reflect your focus change ?
