how to create a sound volume button

This worked for me if anyone needs it 

create excute javascript

DS.appState.setVolume(1);//play sound

DS.appState.setVolume(0); //mute 

Happy first post, Marco!

Great call to reach out to the community for help on designing this. They're a wonderful resource, and I'm excited to see the possibilities! 

For now, here are two related posts that could help:

• Add a custom volume controller in Storyline 3 or Storyline 360
• Custom Audio Controller Using Toggle Button - Mute or Unmute Volume

This custom audioVolume slider works. Uses this code to set the audio.
var allAudios = document.getElementsByTagName("audio");
if (allAudios[0].volume >= 0) {
for (var a = 0; a < allAudios.length; a++) {
allAudios[a].volume = _volume;
}
}

Hello Katie,

This is my first post too :-)

i'm looking for the the same thing as Marco. I've tested your first solution. Does it work anymore  ?

The tutorial say's to replace a file named "app.min.js" who doesn't  exist when i publish their storyLine sample. 

Otherwise on Chrome, the sample generates a javaScript error (see attachment)

i saw this post who says this file doesn't exist anymore in Storyline.
Can you confirm this ?
is there a replacement solution ?

Thank's for your answer

Eric

P.S. : i don't publish in Scorm mode

In the browser this command works in your console...
DS.appState.setVolume(0.2);

I couldnot figure out (yet) how to make that work in Storyline as trigger...

Hello Math,

Thank you for your example. It works fine !
i try to do something with it

If you are comfortable with editing code in the exported files, you can also do the following...

Search the ds-slides.min.js file for parseBlocks,i=DS,r=i._,s=i.utils (this file is minified, so make sure no spaces in the search term.  Then look just before for var e= and insert _c=DS.appState; before the var keyword.  So for example you will see this (the numbers in parenthesis may vary) var e=f(50),n=f(16).parseBlocks,i=DS,r=i._,s=i.utils and you will change it to _c=DS.appState;var e=f(50),n=f(16).parseBlocks,i=DS,r=i._,s=i.utils  

You can then adjust the volume from within Storyline using a javascript trigger and calling _c.setVolume(number from 0 to 1).
