Title: Fade an audio Source to a specific voulme over time
Post by: desktopdaydreams on April 03, 2014, 05:36:15 AM

Hey Folks,

I've been hunting around the forums for a solution to this but can not seem to find a definitive answer.

What we're hoping to do is control the volume of an audio source over x seconds.

An an example, a player camera fades in over time and we want to bring up an audio sources volume form 0 to say 0.5 over 0.5 of a second.

Has anyone come up with a solution to this or will we need to write something custom to handle it?

Thanks for taking the time to read and great work on Playmaker! :)

Best,
Tim

Hi,

 there is a "set audio volume" action, is that not doing the trick? Animate a float from 0.5 to 0 and inject that animated float in this volume action.

bye,

Hi Jean!

Many thanks for the reply. We actually ended writing a small action to handle it. It basically just tweens the volume from one value to another over time.

Thanks for the prompt reply though  ;)

Jean, I was trying this today and I can't seem to get this to work.  I understand the principle, but now how to do it.  Could you give a little more detain in the instructions of how to do this?  Thanks.

Hi,

 Use an animation curve to define your volume curve, and then inject the value from that curve into the volume property.

 Have you tried that?

else, do a float tweening if you don't want an animation curve.

Also, I create last week two actions, audio fade in and audio fade out, that you can get on the ecosystem browser:
