Volume Slider Not Working

I have a slider that controls my volume. It was working fine until I imported the Unity Particle Pack off the Asset Store. The slider doesn't update the mixer's value, but does everything else. My code was unchanged and yes, I have assigned my audio mixer, functions, and all of that. I'm not sure what happened, please help!

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Audio;
3. using UnityEngine.UI;
4.  
5. public class OptionsMenu : MonoBehaviour {
6.  
7.     public AudioMixer mixer;
8.     public Slider slider;
9.  
10.     public void SetVolume(float volume)
11.     {
12.         mixer.SetFloat("Volume", volume);
13.     }
14.  
15.     public void Start()
16.     {
17.         SetVolume(PlayerPrefs.GetFloat("Volume", 0));
18.         slider.value = PlayerPrefs.GetFloat("Volume");
19.     }
20.  
21.     public void OnDisable()
22.     {
23.         float Volume = 0f;
24.  
25.         mixer.GetFloat("Volume", out Volume);
26.  
27.         PlayerPrefs.SetFloat("Volume", Volume);
28.         PlayerPrefs.Save();
29.     }
30.  
31.  
32.  
33.  
34. }

 

EDIT to this old thread I posted... see here for more on dynamic Slider values:

---------------------- my original post:

This is kind of an annoying tricky part about Sliders. The callback shouldn't take a float unless you want a constant float.

Instead you want it to take a

Slider

, from which you pry out the

.value

field. It is discussed here:

I just tested it here with this code:

Code (csharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3.  
4. public class glug : MonoBehaviour {
5.  
6.     public void SetVolume( Slider s)
7.     {
8.         Debug.Log( "fnord:" + s.value);
9.     }
10. }

and my slider setup event looked like:



Don't forget to drag the slider instance itself into argument field.
