Toggle audio group på UI Toggle

Hello

I've been searching high and low, both on google and this forum and I cant believe that I cant find the answer to this;

Surely it must be possible to use a UI - Toggle to mute/unmute an audio group? Just I cant for the life of me find out how...

Help me Unity community...you're my only hope....

 

- Open the mixer
- Select the group you want to mute
- in the inspector, right click on the volume
- click on the "Expose volume (groupname) to script"
See "Exposed parameters" here: https://docs.unity3d.com/Manual/AudioMixerInspectors.html

- in the script you can use the SetFloat to set it to zero: https://docs.unity3d.com/ScriptReference/Audio.AudioMixer.SetFloat.html

 

Many thanks for the reply, Lurking-Ninja, much obliged.

I kinda got things going, albeit in a different way. I have managed to setup two Toggles that will mute and unmute selected audio groups. However, I'm having troubles getting them to save their state to PlayerPrefs independantly of each other.

See my script below; if I comment out anything with FX the music toggle will work and save state as intended. Same if I comment out anything with music, then the FX will work as intended. But if I leave the code as is below, then it seems they inherit each others state. Utterly annoying for what should be a simple issue. Any ideas?

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6.  
7.  
8. public class MainMenu : MonoBehaviour
9. {
10.  
11.     //gameobjects are assigned by drag-and-drop in the inspector
12.     public Toggle fxtogglebtn;
13.     public Toggle musictogglebtn;
14.  
15.     public bool fxbool;
16.     public bool musicbool;
17.  
18.     string fxboolstring;
19.     string musicboolstring;
20.  
21.     // Start is called before the first frame update
22.     void Start()
23.     {
24.  
25.         fxbool = (PlayerPrefs.GetInt(fxboolstring) != 0);
26.         musicbool = (PlayerPrefs.GetInt(musicboolstring) != 0);
27.      
28.         fxtogglebtn.isOn = fxbool;
29.         musictogglebtn.isOn = musicbool;
30.      
31.     }
32.  
33.  
34.  
35.     public void savefxbool()
36.     {
37.  
38.         if (fxtogglebtn.isOn == true)
39.         {
40.  
41.             PlayerPrefs.SetInt(fxboolstring, (true ? 1 : 0));
42.  
43.         }
44.  
45.         if (fxtogglebtn.isOn == false)
46.         {
47.  
48.             PlayerPrefs.SetInt(fxboolstring, (false ? 1 : 0));
49.  
50.         }
51.  
52.  
53.  
54.     }
55.  
56.     public void savemusicbool()
57.     {
58.  
59.         if (musictogglebtn.isOn == true)
60.         {
61.  
62.             PlayerPrefs.SetInt(musicboolstring, (true ? 1 : 0));
63.  
64.         }
65.  
66.         if (musictogglebtn.isOn == false)
67.         {
68.  
69.             PlayerPrefs.SetInt(musicboolstring, (false ? 1 : 0));
70.  
71.         }
72.  
73.     }
74.  
75.  
76.  
77. }
78.  

 

Bumping this thread just once. Really cant figure out why my FX routines and Music routines work independantly of each other, but not when both are active at the same time...

 

EDIT - scratch this thread...@Lurking-Ninja, again thanks for your help. I'm using SetFloat to set volume instead with exposed parameters as you suggested. For reference to others; https://unity3d.com/learn/tutorials/topics/audio/exposed-audiomixer-parameters?playlist=17096
