simple question about coroutine an audio (I want to fade out music in javascript)
So I have a javascript game I am redoing and almost done. In one of the functions I call the coroutine to adjust the audio. It does this ok, but I can't set the length. How do you do that.
So looking at the script, I have a variable at the top 'linkToMusic;. This is set in the inspector to another game object that holds the msic.
I then (in a function) call the coroutine 'FadeAudioOut();'.
In the corotuine, I am trying to fade out the music over a 1 second real time period to match up with the video fade out to back.
So basically, it's just how do I set the time in the coroutine to 1 second fade to 0 or even a 2 second fade to 0?

{
linkToMusic.GetComponent.<AudioSource>().volume -= Time.deltaTime;
yield;
}
}

Don't just ask a new question every time you run into a problem. Search for it first.
Type "unity how to fade out audio javascript" into google.

The accepted answer there contains code:
function Update(){ if (Input.Get$$anonymous$$eyDown("F")){ FadeOutSound(); } } var menu$$anonymous$$usic:GameObject; function FadeOutSound(){ if (!menu$$anonymous$$usic){ // Get menu$$anonymous$$usic if not already defined in Inspector menu$$anonymous$$usic = GameObject.Find("$$anonymous$$enu$$anonymous$$usic"); } if (menu$$anonymous$$usic) { // wait 4 seconds then fades for 4.5s yield WaitForSeconds (4); for (var i = 9; i > 0; i--){ menu$$anonymous$$usic.audio.volume = i * .1; yield new WaitForSeconds (.5); print ("Fading..."); } menu$$anonymous$$usic.audio.volume = 0; } }Copy it into Unity.
Unity says that scripts contain obsolete API's. It will adapt those automatically if you click yes.
Open script. It adapted the GetComponent() command, which you already use in your script.
function Update(){ if (Input.Get$$anonymous$$eyDown("F")){ FadeOutSound(); } } var menu$$anonymous$$usic:GameObject; function FadeOutSound(){ if (!menu$$anonymous$$usic){ // Get menu$$anonymous$$usic if not already defined in Inspector menu$$anonymous$$usic = GameObject.Find("$$anonymous$$enu$$anonymous$$usic"); } if (menu$$anonymous$$usic) { // wait 4 seconds then fades for 4.5s yield WaitForSeconds (4); for (var i = 9; i > 0; i--){ menu$$anonymous$$usic.GetComponent.<AudioSource>().volume = i * .1; yield new WaitForSeconds (.5); print ("Fading..."); } menu$$anonymous$$usic.GetComponent.<AudioSource>().volume = 0; } }Drag an AudioSource onto "menu$$anonymous$$usic" and run scene.
$$anonymous$$ake sure the audio plays.
Press F.
Unity says: ArgumentException: Input $$anonymous$$ey named: F is unknownLook at script. Change the line using
$$anonymous$$eyCode.Fins$$anonymous$$d of"F".If for some reason you don't know about $$anonymous$$eyCodes, you can always google the error and find the information within 2 seconds.Save script. Run the scene. Press F. Look at the Inspector. It fades to 0.
It took me 10 $$anonymous$$utes to:
google "unity how to fade out audio javascript", read a bit of the surrounding texts.
copy the code from there to my scene, convert it and try it with an audiosource.
google "ArgumentException: Input $$anonymous$$ey named: F is unknown".
You spent "hours" searching, but couldn't just try what others said, even if it was years ago.
You should have a look at this. It is also featured in the FAQ:

Actually I did this and it worked fine. Thanks for your help.
var linkToMusic : GameObject;
enum Fade {In, Out}
var fadeTime = 1.0;
