Setting the volume of streams and nodes

Troubleshooting sound
1

Me again :wink:



First, I wonder if there’s a way to set the volume of a stream?



Second, I’ve added this method in my copy of the SoundSystem:


    /**
     * Sets the volume of all samples attached to a given node.
     *
     * @param node We change the volume of this nodes children.
     * @param volume The volume to set. Should be a value between 0 - 1.
     */
    public static void setNodeVolume(int node, float volume) {
       for (int i = 0; i < nodes[node].getQuantity(); i++) {
          Sample3D sample = (Sample3D) nodes[node].getChild(i);
          sample.setVolume(volume);
       }
    }



It feels like a good complement to the "setSampleVolume" method.

Yeah, I’m wondering about that too. Anyone? Anyone?

ok this was done :slight_smile:

I can see the setNodeVolume method but not a way to change the volume of a stream?

5

Aww, I’ll add it as soon as possible

Cool, thanks.

setNodeVolume didn’t quite do what I expected. Seems that it only really works on sounds currently playing on the node. That’s fine I guess, but I was wondering if we could add this to the soundManager?


   
    public static void setMasterVolume(int vol){
       FSound.FSOUND_SetSFXMasterVolume(vol);
    }



Merci

BTW, if you want to be able to change stream volume just add this to SoundSystem:


   
    public static void setStreamVolume(int sample, int vol){
       stream[sample].setVolume(vol);
    }



And this to Music Stream:

       
    public void setVolume(int vol){
       FSound.FSOUND_SetVolume(playingChannel, vol);
    }



There ya go.

I played a bit with Sound recently and found a volume control missing in openAL stream handling



following code is only confirmed to work in my app on my machine so please test / correct and add to cvs as you see fit…



i did:



public void setVolume(float vol)
{
      AL10.alSourcef(source, AL10.AL_GAIN, vol);
}



to private class Player in com.jmex.sound.openAL.objects.util.StreamPlayer.java
and


public void setStreamVolume(int streamNumber, float vol)
{
        if(player!=null && streamNumber>=0 && streamNumber <= player.length)
        {
            player[streamNumber].setVolume(vol);
        }
}



to class StreamPlayer in com.jmex.sound.openAL.objects.util.StreamPlayer.java
and



public void setVolume(int soueceNumber, float volume)
    {
        StreamPlayer.getInstance().setStreamVolume(sourceNumber, volume);
    }



to class MusicStream in com.jmex.sound.openAL.objects.MusicStream.java


and


public static void setStreamVolume(int streamName, float vol)
{
        stream[streamName].setVolume(streamName, vol);   
}



to class SoundSystem in com.jmex.sound.openAL.SoundSystem.java


i hope i didn't forget / mess up something in copy and paste process...

BTW:  Is Arman still maintaining this ? as i haven't seen something from him in a while ?

Hi,



This issue is still open? At least I cannot find a volume control for streams.
