Storyline 360 In-Story Volume Control Scripts

Jul 13, 2017

Skip to the bottom for the bolded question for TLDR. So I've added continuous, looping background music to my presentation, and added a volume slider to adjust that. This is the script I use to begin the music:

var player = GetPlayer();
this.Location= player.GetVar("location");

var audio = document.getElementById('bgSong');
audio.src=Location + "Corporate Background.mp3";
audio.load();
audio.play();

The slider was connected to a variable called "volumeCount" (from http://www.swiftelearningservices.com/how-to-create-custom-volume-controls-in-articulate-storyline-2/) - and it does not work at all. So instead, I used the regular volume adjustment to match the corresponding volume of the background music to the position of the slider (1-10), and it worked brilliantly for the background music. The script (ex/ for 1) looks like this:

var audio = document.getElementById('bgSong');
audio.volume = 0.01;

Unfortunately, this only changes the background music. I tried to incorporate this with the script used from the link above, which is:

var player = GetPlayer();
var volumeCount = player.GetVar('volumeCount')
Audio.setMasterVolume(volumeCount);

and I could not get it to work. I want to connect this slider, in the exact same way, to the master volume of the in-presentation volume (the narration). How do I make this work?!?! I know little to nothing about java.

Hi,

try this:

var player = GetPlayer();
 var volumeCount = player.GetVar('volumeCount')
//Audio.setMasterVolume(volumeCount);//there is no Audio in SL360 as it was in SL2

var audio = document.getElementById('bgSong');
 audio.volume = volumeCount;

can you tell me how you put reference (bgSong) to your audio in slide?

I have found a solution, and described it here on my blog but for those who dont want to click on the link below is the script:

var player = GetPlayer();
var volumeCount = player.GetVar("volumeCount") / 10;
var appState = require("helpers/appState");
appState.currentVolume(volumeCount);

Lukasz, Fabulous idea!!

I am not great at coding - but I am desperately trying to get your code to work on a toggle button - so click one object audio mutes, click another object it resumes - any hints??

Thanks so much!!

Hi Donna,

on the click button action use this code:

var appState = require("helpers/appState");
 appState.onToggleVolume();//mute/unmute

to find out in what audio state it is:

test the appState.volumeToggle property.

Lukacz, I salute you - you have literally saved my life... I have a project due for delivery tomorrow in SL3, I was using the old method from SL2 - and at the 11th hour realised it was no longer functioning!! Without your fix I would have had to rebuild the entire project from the ground up in SL2 just so one button would work! I owe you a beer! :)
