Control volume within lens
I am trying to give users the ability to adjust the volume within the lens. I have noticed some lenses will take a picture or record when volume buttons are pressed on the device while others control the volume of the device.
Is there a setting or script that reliably sets what behavior the external buttons have?
Here is a portion of a script that handles playing audio when a marker is detected but the audio.volume=100 line has no effect.
// Wait for 2 seconds before starting Audio
delayedAudioEvent = script.createEvent("DelayedCallbackEvent");
delayedAudioEvent.enabled=true;
delayedAudioEvent.bind(function(eventData)
{
print("Playing Audio....")
if(script.audio){
print("audio:"+ script.audio)
script.audio.volume= 100;
script.audio.play( -1 );
}
});

Hey there Paul,
You have the right idea, the only thing you need to change is the volume number. Instead of the number being between 1-100, it is between 0 and 1. So if you wanted your volume at half of its normal amount, you'd set it to 0.5. From what I can tell, you can't increase the volume more than 1, which is its default volume.
Hope that helps!

Hi Ben,
I had initially started with the 0-1 range but did not notice an effect so I was just testing out 0-100 since the documentation did not specify a range.
After further investigation of existing lenses, my biggest question is how game style lenses allow for volume control using external buttons vs other lenses take a recording when volume buttons are pressed.
