Audio Source and Audio Listener fixes

I added a script to the wiki so that we all can have improved audio volume control in Unity. It's really simple; I just figured I would put it here because I think it would be useful to everybody who employs sound in their projects. Check out this thread for information on why this is useful.

 

Thanks! Thats a great help! I was just working on a project that needed sound control too!

A great addition! Thanks.

 

I have created something of a monster on the wiki, but I hope it is a useful beast. Please let me know how this works out for you, and if you have any suggestions for improvement.

I don't know if it's possible in Javascript but in C# there is what they call properties. It allows you to modify a variable and also do other stuffs at the same time.

Here is your code:

Code (csharp):

1. var volume : float = 1;
2.  
3. // determines whether "RefreshVolume" will run in Update(),
4. // or must be called manually
5. var performanceMode = false;
6.  
7. private var loudnessExponent = Mathf.Log(Mathf.Sqrt(10), 2);
8.  
9. function RefreshVolume ()
10.     {audioListener.volume = Mathf.Pow(volume, loudnessExponent);}
11.  
12. function Start ()
13.     {RefreshVolume ();}
14.  
15. function Update ()
16. {
17. if (performanceMode == false)
18.              RefreshVolume ();
19. }

Here is what he would become (untested)

Code (csharp):

1.  
2. //C#
3. private float m_iVolume = 1.0f;
4. private float m_iLoudnessExponent = Mathf.Log(Mathf.Sqrt(10), 2);
5. public float Volume
6. {
7.   get {return m_iVolume;}
8.   set
9.   {
10.     m_iVolume = value;
11.     RefreshVolume();
12.   }
13. }
14.  
15. void RefreshVolume()
16. {
17.   audioListener.volume = Mathf.Pow(m_iVolume, m_iLoudnessExponent);}
18. }
19.  
20. void Start()
21. {
22.   Volume = 0.5f; // This way it updates the variable and calls RefreshVolume()
23. }
24.  

Again this is untested but you should get the idea.
I find properties super usefuls in C#...

 

JavaScript Properties are on the wish list at feedback.unity3d.com.

Updated with improved usability/documentation and C# support.

I utilized Properties with C#, and came as close as I could come up with using JavaScript. Thanks for the suggestion, Scrat.
