AudioSource silent in space

[N3h3mia]

Hi I added some sound effects to my IVA. Therefore I'm adding an AudioSource to a part.

alarmAs = light.AddComponent<AudioSource>();
AudioClip clip = GameDatabase.Instance.GetAudioClip(alarmSound);
alarmAs.clip = clip;
alarmAs.dopplerLevel = DOPPLER_LEVEL;
alarmAs.rolloffMode = AudioRolloffMode.Linear;
alarmAs.Stop();
alarmAs.loop = true;
alarmAs.minDistance = MIN_DIST;
alarmAs.maxDistance = MAX_DIST;
alarmAs.volume = 1f;

if (!alarmAs.isPlaying)
{
     alarmAs.Play();
}

When I test it on the launch pad everything works well, but when i hyperedit my test craft into orbit I can't hear the sound effects. I can't find the reason for this. Can anybody explain this behavior?

maybe your sound stays at the launchpad..

in terms of:

the parent value of the audio-gameobject is not set correctly..

so if the ship moves, the audio stays at the global location it is created..

alarmAs.transform.parent = ???

or

light.transform.parent = ???

the light is a part of the iva 3d-model and the parent is set to parent in the model. As I understand it component do not have their own transform. so if the model moves so should the audio source. Or did I miss something.

I did some testing, when I add the Audiosource component to the internalModel the audiosource stays where it was added, when I add the component to the part itself it moves with the craft. It behaves like the iva would stay in one place even if the craft is moving. Can somebody explain this? For the time I'll add the audio to the part.

I juts saw, you are swiss - so am I lol..

>As I understand it component do not have their own transform.

This is wrong and right..

components do not have an own but they are added to a game object - and this game object has a transform..

>Can somebody explain this? For the time I'll add the audio to the part.

I can't.. sorry..

I don't know if that is "normal" but I doubt it..

never seen this - so it might be something wrong in your set up..

That's what I meant. The light has a mesh component, so if it would stay in a place so should the mesh but only the AudioSource doesn't move.

>I don't know if that is "normal" but I doubt it.

I doubt it too, but IVA's to behave strange sometimes, at least for me they do.

I would parent the GO to something that moves - if it works, call it "done"..

Valid is what wroks..

and old coder rule...

There is a bug with the IVA light sources. If you move a craft with an IVA away from its starting point, you can see that the IVA light remains there, lighting up the ground. You appear to be attaching your sound to this bugged light. You can test this with your sound by driving a rover away from the start point and seeing if the sound stays with it. Parent the sound to the IVA part's GameObject to have the effect you're looking for.

I did some testing with a rover and can confirm that the sound stays in it's starting point. But it is not limited to lights. I have the same problem with an other IVA there I attach the AudioSource to a GameObject that is not a light. It is the GameObject holding the model for this part in the IVA.

Here is the method used to add the AudioSource. maybe somebody can point out my error. It is part of a class that is an InternalModule not a PartModule.

private void initPartObjects()
        {
            if (part.internalModel != null)
            {
                GameObject labIVA = part.internalModel.gameObject.transform.GetChild(0).GetChild(0).gameObject;
                if (labIVA.GetComponent<MeshFilter>().name == "Lab1IVA")
                {
                    GameObject ffr = labIVA.transform.GetChild(2).gameObject;
                    pump1 = ffr.transform.GetChild(1);
                    pump2 = ffr.transform.GetChild(2);

                    //pumpAs = ffr.AddComponent<AudioSource>(); //Does not work
                    pumpAs = part.gameObject.AddComponent<AudioSource>(); //Workaround: using GameObjects from the internal model does not work AS would stay in the place it was added.

                    AudioClip clip = GameDatabase.Instance.GetAudioClip(pumpSound);
                    pumpAs.clip = clip;
                    pumpAs.dopplerLevel = DOPPLER_LEVEL;
                    pumpAs.rolloffMode = AudioRolloffMode.Logarithmic;
                    pumpAs.Stop();
                    pumpAs.loop = true;
                    pumpAs.minDistance = MIN_DIST;
                    pumpAs.maxDistance = MAX_DIST;
                    pumpAs.volume = 1f;
                }
            }
        }
