Slider not updating

Unity Engine
1

I have a slider that controls my music volume. It works fine, but if you return to the options menu after going to another scene the slider is at max even though the actual volume is whatever you set it to. Is there a way to update the slider? Here is my code.

using UnityEngine;
using UnityEngine.Audio;

public class OptionsMenu : MonoBehaviour {

    public AudioMixer mixer;

    public void SetVolume(float volume)
    {
        mixer.SetFloat("Volume", volume);
    }

    public void Start()
    {
        SetVolume(PlayerPrefs.GetFloat("Volume", 0));
    }

    public void OnDisable()
    {
        float Volume = 0f;

        mixer.GetFloat("Volume", out Volume);

        PlayerPrefs.SetFloat("Volume", Volume);
        PlayerPrefs.Save();
    }




}

You need to update the slider to reflect the volume.

Reference the slider and set its value to the “Volume” key in the Start function.

How do I reference it?

4

Add a public variable of type Slider to your code and then assign it in the inspector.

5

I can’t set it to the volume key. How can I set it?

6

How do you set the slider to a key?

7

Set the value from the “Volume” PlayerPref key that you are using.

volumeSlider.value = PlayerPrefs.GetFloat("Volume");
