Volume issue

by Abhinav Chokhavatia · in Torque Game Builder · 06/17/2008 (2:26 am) · 6 replies

Hey guys!

I was trying to create a volume control GUI for my game and I wanted to change the volume of the backgroud music on the fly. Is there a function which I can call to change the volume of the music? Below is my code.

$bgmusic = alxPlay (bgmusic);
%newVolume = 0.8;
(I dont know what to put here for changing the volume)

I don't have my code handy with me, but you basically need to assign the music track to the a channel in your datablock, then adjust the volume of that channel with the function alxSetChannelVolume(channel, volume).

I'll post some code when I get home from work...

You can also check out the options gui and related scripts in the common folder. There is an options gui with the ability to set music/sfx volume in stock TGB.

Abhinav,

You want to use updateChannelVolume(). For example, here's the script that I placed in the "altcommand" of my guiSliderCtrl control: 

updateChannelVolume($AudioType::music, ui_music_slider.value)

Where $AudioType::music is the audio channel of the sound (set in the audio description datablock) and ui_music_slider is the name of the gui control.

I can update the value of my AudioDescription using this line:

updateChannelVolume(myAudioDatablock.volume = 0.3);

but the change is only reflected is I use AlxStop and then play the sound again. How can this works inmediately?

Thanks

If you want to change the sound on a particular sound only, and not the entire channel, you can use this:

// %handle is the return value from alxPlay(mySound);
// %volume is the volume you want it set to (lies between 0.0 and 1.0)
alxSourcef(%handle, "AL_GAIN", %volume);

Thanks Phillip
