    private Button button;

    void Awake()
    {
        button = GetComponent<Button>();
        if (button != null)
        {
            button.onClick.AddListener(OnButtonClick);
        }
    }

    void OnDestroy()
    {
        if (button != null)
        {
            button.onClick.RemoveListener(OnButtonClick);
        }
    }

    void OnButtonClick()
    {
        if (clickEvent != null)
        {
            clickEvent.Post();
        }
    }

Recipe: Settings Menu with Volume Sliders

📋 What: Complete audio settings menu with persistence

🎯 Use Case: Options menu, settings screen

💻 Code:

using UnityEngine;
using UnityEngine.UI;
using AudioSystem;

public class AudioSettingsMenu : MonoBehaviour
{
    [Header("UI References")]
    [SerializeField] private Slider masterSlider;
    [SerializeField] private Slider sfxSlider;
    [SerializeField] private Slider musicSlider;
    [SerializeField] private Slider dialogueSlider;

    [Header("Audio Events")]
    [SerializeField] private AudioEvent testSFXEvent;

    private const string MASTER_KEY = "Audio_MasterVolume";
    private const string SFX_KEY = "Audio_SFXVolume";
    private const string MUSIC_KEY = "Audio_MusicVolume";
    private const string DIALOGUE_KEY = "Audio_DialogueVolume";

    void Start()
    {
        LoadSettings();
        SetupListeners();
        ApplySettings();
    }

    void LoadSettings()
    {
        masterSlider.value = PlayerPrefs.GetFloat(MASTER_KEY, 1f);
        sfxSlider.value = PlayerPrefs.GetFloat(SFX_KEY, 1f);
        musicSlider.value = PlayerPrefs.GetFloat(MUSIC_KEY, 1f);
        dialogueSlider.value = PlayerPrefs.GetFloat(DIALOGUE_KEY, 1f);
    }

    void SetupListeners()
    {
        masterSlider.onValueChanged.AddListener(OnMasterVolumeChanged);
        sfxSlider.onValueChanged.AddListener(OnSFXVolumeChanged);
        musicSlider.onValueChanged.AddListener(OnMusicVolumeChanged);
        dialogueSlider.onValueChanged.AddListener(OnDialogueVolumeChanged);
    }

    void ApplySettings()
    {
        OnMasterVolumeChanged(masterSlider.value);
        OnSFXVolumeChanged(sfxSlider.value);
        OnMusicVolumeChanged(musicSlider.value);
        OnDialogueVolumeChanged(dialogueSlider.value);
    }

    void OnMasterVolumeChanged(float value)
    {
        AudioManager.Instance.SetMasterVolume(value);
        PlayerPrefs.SetFloat(MASTER_KEY, value);
        PlayerPrefs.Save();
    }

    void OnSFXVolumeChanged(float value)
    {
        SetPlayerVolume("SFX", value);
        PlayerPrefs.SetFloat(SFX_KEY, value);
        PlayerPrefs.Save();
    }

    void OnMusicVolumeChanged(float value)
    {
        SetPlayerVolume("Music", value);
        PlayerPrefs.SetFloat(MUSIC_KEY, value);
        PlayerPrefs.Save();
    }

    void OnDialogueVolumeChanged(float value)
    {
        SetPlayerVolume("Dialogue", value);
        PlayerPrefs.SetFloat(DIALOGUE_KEY, value);
        PlayerPrefs.Save();
    }

    // The player's volume on a bus (Manual §6.8): on top of the mix, never saved into the bus asset,
    // and a mix state can't undo it. Not SetBusVolume, which changes the bus's own Volume.
    void SetPlayerVolume(string busName, float linear)
    {
        var bus = AudioManager.Instance.GetBus(busName);   // an unknown name warns once
        if (bus != null)
            bus.PlayerVolumeDb = AudioSystem.AudioExtensions.LinearToDb(linear);  // qualified: Unity 6.3 has its own AudioExtensions
    }

    // Call this from a "Test" button
    public void PlayTestSound()
    {
        if (testSFXEvent != null)
        {
            testSFXEvent.Post();
        }
    }
}

UI Setup:

1. Create 4 Sliders (Master, SFX, Music, Dialogue)
2. Set slider range: 0 to 1
3. Create “Test Sound” button
4. Attach script to settings panel
5. Assign references

✅ Result: Full audio settings with persistence and test button!

💡 Why PlayerVolumeDb and not SetBusVolume: SetBusVolume changes the bus’s own Volume, the mix you authored. In the editor a Play-mode change stays in the asset, and a state that sets the bus’s level overwrites the player’s choice. The player’s volume is a separate level on top. Example08_AudioSettingsUI is the full version.
