前言

在游戏开发中，音乐和音效的管理是一个重要的环节。好的音乐和合适的音效可以为游戏增添氛围并提升玩家的体验。为了更好地管理音乐和音效，我们可以封装一个专门的音乐和音效管理器。

一、音频管理器

1、初始化

创建播放BGM背景音乐、Sound音效、BGS环境音效、MS提示音效、Voice角色语音的游戏对象

/// <summary>
/// 音频管理器
/// </summary>
public class AudioManager : SingletonMono<AudioManager>
{
    
    
	//各个声道的AudioSource组件
	AudioSource bgmAudioSource;
	AudioSource bgsAudioSource;
	AudioSource voiceAudioSource;
	
	//各个声道的游戏对象
	GameObject bgmController;
	GameObject soundController;
	GameObject bgsController;
	GameObject msController;
	GameObject voiceController;
        
	//控制器的名字
    string bgmControllerName = "BgmController";
    string soundControllerName = "SoundController";
    string bgsControllerName = "BgsController";
    string msControllerName = "MsController";
    string voiceControllerName = "VoiceController";

	void Awake()
    {
    
    
        //创建并设置背景音乐的控制器
        bgmController = CreateController(bgmControllerName, transform);
        bgmAudioSource = bgmController.AddComponent<AudioSource>();
        bgmAudioSource.playOnAwake = false;
        bgmAudioSource.loop = true;

        //创建音效控制器
        soundController = CreateController(soundControllerName, transform);

        //创建并设置环境音效的控制器
        bgsController = CreateController(bgsControllerName, transform);
        bgsAudioSource = bgsController.AddComponent<AudioSource>();
        bgsAudioSource.playOnAwake = false;
        bgsAudioSource.loop = true;

        //创建提示音效的控制器
        msController = CreateController(msControllerName, transform);

        //创建并设置角色语音的控制器
        voiceController = CreateController(voiceControllerName, transform);
        voiceAudioSource = voiceController.AddComponent<AudioSource>();
        voiceAudioSource.playOnAwake = false;
        voiceAudioSource.loop = false;
     }
        
	GameObject CreateController(string name, Transform parent)
	{
    
    
	    GameObject go = new GameObject(name);
	    go.transform.SetParent(parent);
	    return go;
	}
}

2、播放、暂停、取消暂停、停止BGM

/// <summary>
/// 播放BGM
/// </summary>
/// <param name="bgm">背景音乐</param>
/// <param name="loop">是否循环</param>
public void PlayBGM(AudioClip bgm, bool loop = true)
{
    
    
    if (bgm == null)
    {
    
    
        Debug.LogWarning("播放BGM失败！要播放的BGM为null");
        return;
    }

    bgmAudioSource.loop = loop;
    bgmAudioSource.clip = bgm;
    bgmAudioSource.Play();
}

/// <summary>
/// 暂停BGM
/// </summary>
public void PauseBGM()
{
    
    
    bgmAudioSource.Pause();
}

/// <summary>
/// 取消暂停BGM
/// </summary>
public void UnPauseBGM()
{
    
    
    bgmAudioSource.UnPause();
}

/// <summary>
/// 停止BGM
/// </summary>
public void StopBGM()
{
    
    
    bgmAudioSource.Stop();
    bgmAudioSource.clip = null;
}

测试调用

public class AudioTest : MonoBehaviour
{
    
    
    AudioClip BGM1;
    AudioClip BGM2;
    
    void Start()
    {
    
    
        BGM1 = Resources.Load<AudioClip>("Audio/Bgm/BGM1");
        BGM2 = Resources.Load<AudioClip>("Audio/Bgm/BGM2");
    }

    private void OnGUI()
    {
    
    
        GUIStyle buttonStyle = new GUIStyle(GUI.skin.button);   
        buttonStyle.fontSize = 50; // 设置字体大小

        if (GUI.Button(new Rect(0, 0, 400, 150), "播放BGM1", buttonStyle))
        {
    
    
            AudioManager.Instance.PlayBGM(BGM1);
        }
        if (GUI.Button(new Rect(0, 150, 400, 150), "播放BGM2", buttonStyle))
        {
    
    
            AudioManager.Instance.PlayBGM(BGM2);
        }
        if (GUI.Button(new Rect(0, 300, 400, 150), "暂停BGM", buttonStyle))
        {
    
    
            AudioManager.Instance.PauseBGM();
        }
        if (GUI.Button(new Rect(0, 450, 400, 150), "取消暂停BGM", buttonStyle))
        {
    
    
            AudioManager.Instance.UnPauseBGM();
        }
        if (GUI.Button(new Rect(0, 600, 400, 150), "停止BGM", buttonStyle))
        {
    
    
            AudioManager.Instance.StopBGM();
        }
    }
}

3、播放2D音效

/// <summary>
/// 播放2D音效
/// </summary>
public void PlaySound(AudioClip sound)
{
    
    
    //临时的空物体，用来播放音效。
    GameObject go = new GameObject(sound.name);

	//设置父物体
	go.transform.SetParent(soundController.transform);

    //如果该游戏对象身上没有AudioSource组件，则添加AudioSource组件并设置参数。
    if (!go.TryGetComponent<AudioSource>(out AudioSource audioSource))
    {
    
    
        audioSource = go.AddComponent<AudioSource>();
        audioSource.playOnAwake = false;
        audioSource.loop = false;
    }

    //设置要播放的音效
    audioSource.clip = sound;

    //播放音效
    audioSource.Play();

    //每隔1秒检测一次，如果该音效播放完毕，则销毁音效的游戏对象。
    StartCoroutine(DestroyWhenFinished());

    //每隔1秒检测一次，如果该音效播放完毕，则销毁音效的游戏对象。
    IEnumerator DestroyWhenFinished()
    {
    
    
        do
        {
    
    
            yield return new WaitForSeconds(1);

            if (go == null || audioSource == null) yield break;//如果播放音频的游戏对象，或者AudioSource组件被销毁了，则直接跳出协程。
        } while (audioSource != null && audioSource.time > 0);

        if (go != null) Destroy(go);
    }
}

调用

AudioManager.Instance.PlaySound(Sound1);

4、在指定目标对象身上播放3D音效

/// </summary>
/// <summary>
/// 在指定目标对象身上播放3D音效
/// </summary>
/// <param name="sound">音效</param>
/// <param name="target">目标</param>
public void PlaySound(AudioClip sound, GameObject target)
{
    
    
    if (sound == null)
    {
    
    
        Debug.LogWarning("播放Sound失败！要播放的Sound为null");
        return;
    }

    if (target == null)
    {
    
    
        Debug.LogWarning("播放Sound失败！无法在目标对象身上播放Sound，因为目标对象为null");
        return;
    }

    //临时的空物体，用来播放音效。
    GameObject go = new GameObject(sound.name);

    //把用于播放音效的游戏对象放到目标物体之下，作为它的子物体
    go.transform.SetParent(target.transform);
    go.transform.localPosition = Vector3.zero;

    //如果该游戏对象身上没有AudioSource组件，则添加AudioSource组件并设置参数。
    if (!go.TryGetComponent<AudioSource>(out AudioSource audioSource))
    {
    
    
        audioSource = go.AddComponent<AudioSource>();
        audioSource.playOnAwake = false;
        audioSource.loop = false;
        audioSource.spatialBlend = 1f;//3D效果，近大远小。
    }

    //设置要播放的音频
    audioSource.clip = sound;

    //播放音频
    audioSource.Play();

    //每隔1秒检测一次，如果该音频播放完毕，则销毁游戏对象。
    StartCoroutine(DestoryWhenFinisied());

    //每隔1秒检测一次，如果该音频播放完毕，则销毁游戏对象。
    IEnumerator DestoryWhenFinisied()
    {
    
    
        do
        {
    
    
            yield return new WaitForSeconds(1);

            if (go == null || audioSource == null) yield break;//如果播放音频的游戏对象，或者AudioSource组件被销毁了，则直接跳出协程。
        } while (audioSource != null && audioSource.time > 0);

        if (go != null) Destroy(go);
    }
}

调用

AudioManager.Instance.PlaySound(Sound2, gameObject);

5、音效对象池

其实之前我们已经写过了对象池管理器：【unity进阶知识7】对象池的使用，如何封装一个对象池管理器

但是为了降低代码耦合性，就不用之前的对象池管理器了，我们从新建一个音频对象池，专门用来对音频服务

新增AudioObjectPool 音频对象池代码

/// <summary>
/// 音频对象池
/// </summary>
public class AudioObjectPool : Singleton<AudioObjectPool>
{
    
    
    /// <summary>
    /// 获取对象
    /// </summary>
    /// <param name="SoundPool">对象池</param>
    /// <param name="parent">父级</param>
    /// <returns></returns>
    public GameObject Spawn(GameObject SoundPool, Transform parent = null)
    {
    
    
        GameObject go = null;
        for (int i = 0; i < SoundPool.transform.childCount; i++)
        {
    
    
            //如果对象池中有，则从对象池中取出来用。
            if (!SoundPool.transform.GetChild(i).gameObject.activeSelf)
            {
    
    
                go = SoundPool.transform.GetChild(i).gameObject;
                go.SetActive(true);
                break;
            }
        }
        //如果对象池中没有，则创建一个游戏对象。
        go = go ? go : new GameObject(SoundPool.name + "_Pool");

        if (parent) go.transform.SetParent(parent);

        go.transform.localPosition = Vector3.zero;


        return go;
    }

    /// <summary>
    /// 回收对象
    /// </summary>
    /// <param name="go">对象</param>
    /// <param name="parent">父级</param>
    public void Despawn(GameObject go, Transform parent = null)
    {
    
    
        if (parent) go.transform.SetParent(parent);
        go.transform.localPosition = Vector3.zero;

        go.SetActive(false);
    }
}

6、封装用对象池播放音效方法

/// <summary>
/// 播放音效
/// </summary>
/// <param name="sound">音效</param>
/// <param name="controller">对象池</param>
/// <param name="worldPosition">世界空间的位置</param>
/// <param name="parent">父级</param>
/// <param name="is3D">是否是3D音效</param>
void PlaySound(AudioClip sound, GameObject controller, Vector3 worldPosition, Transform parent = null, bool is3D = false)
{
    
    
    if (sound == null)
    {
    
    
        Debug.LogWarning("播放Sound失败！要播放的Sound为null");
        return;
    }

    GameObject go = AudioObjectPool.Instance.Spawn(controller, parent);

    //如果该游戏对象身上没有AudioSource组件，则添加AudioSource组件
    if (!go.TryGetComponent<AudioSource>(out AudioSource audioSource))
    {
    
    
        audioSource = go.AddComponent<AudioSource>();
    }

    if(is3D) audioSource.spatialBlend = 1f;//3D效果，近大远小。

    go.transform.position = worldPosition;

    //播放音效
    StartCoroutine(PlaySoundCoroutine(go, sound, controller.transform));
}

/// <summary>
/// 携程控制播放音效
/// </summary>
/// <param name="go">音频对象</param>
/// <param name="sound">音效</param>
/// <param name="parent">回收父级</param>
/// <returns></returns>
IEnumerator PlaySoundCoroutine(GameObject go, AudioClip sound, Transform parent = null)
{
    
    
    AudioSource audioSource = go.GetComponent<AudioSource>();
    //播放音效
    audioSource.PlayOneShot(sound);
    
    // 等待音效播放完成
    yield return CoroutineTool.WaitForSeconds(sound.length);
    
    // 音效播放完成后的逻辑
    audioSource.clip = null;
    AudioObjectPool.Instance.Despawn(go, parent);//放入对象池
}

7、使用对象池播放2D音效

/// <summary>
/// 播放2D音效
/// </summary>
public void PlaySound(AudioClip sound)
{
    
    
    PlaySound(sound, audioGameObjects[E_AudioController.Sound2DController], Vector3.zero);
}

8 使用对象池在指定目标对象身上播放3D音效

/// </summary>
/// <summary>
/// 在指定目标对象身上播放3D音效
/// </summary>
/// <param name="sound">音效</param>
/// <param name="target">目标</param>
public void PlaySound(AudioClip sound, Transform target)
{
    
    
    PlaySound(sound, audioGameObjects[E_AudioController.Sound3DController], Vector3.zero, target, true);
}

9、使用对象池在世界空间中指定的位置播放3D音效

/// <summary>
/// 在世界空间中指定的位置播放3D音效
/// </summary>
public void PlaySound(AudioClip sound, Vector3 worldPosition)
{
    
    
    PlaySound(sound, audioGameObjects[E_AudioController.Sound3DController], worldPosition, null, true);
}

10、播放、暂停、取消暂停、停止BGS环境音效，和bgm差不多

/// <summary>
/// 播放环境音效
/// </summary>
public void PlayBGS(AudioClip bgs, bool loop = true)
{
    
    
    if (bgs == null)
    {
    
    
        Debug.LogWarning("播放BGS失败！要播放的BGS为null");
        return;
    }

    bgsAudioSource.loop = loop;
    bgsAudioSource.clip = bgs;
    bgsAudioSource.Play();
}

/// <summary>
/// 暂停环境音效
/// </summary>
public void PauseBGS()
{
    
    
    bgsAudioSource.Pause();
}

/// <summary>
/// 取消暂停环境音效
/// </summary>
public void UnPauseBGS()
{
    
    
    bgsAudioSource.UnPause();
}

/// <summary>
/// 停止BGS
/// </summary>
public void StopBGS()
{
    
    
    bgsAudioSource.Stop();
    bgsAudioSource.clip = null;
}

测试调用

//BGS环境音
if (GUI.Button(new Rect(width*2, 0, width, height), "播放环境音1", buttonStyle))
{
    
    
    AudioManager.Instance.PlayBGS(BGS1);
}
if (GUI.Button(new Rect(width*2, height, width, height), "播放环境音2", buttonStyle))
{
    
    
    AudioManager.Instance.PlayBGS(BGS2);
}
if (GUI.Button(new Rect(width*2, height*2, width, height), "暂停环境音", buttonStyle))
{
    
    
    AudioManager.Instance.PauseBGS();
}
if (GUI.Button(new Rect(width*2, height*3, width, height), "取消暂停环境音", buttonStyle))
{
    
    
    AudioManager.Instance.UnPauseBGS();
}
if (GUI.Button(new Rect(width*2, height*4, width, height), "停止环境音", buttonStyle))
{
    
    
    AudioManager.Instance.StopBGS();
}

11、使用对象池播放MS提示音效

/// <summary>
/// 播放提示音效
/// </summary>
/// <param name="ms">提示音效</param>
public void PlayMS(AudioClip ms)
{
    
    
    PlaySound(ms, audioGameObjects[E_AudioController.MsController], Vector3.zero);
}

12、播放和停止Voice角色语音

当然角色语言也可以通过3D的方式播放，代入感更强，具体取决于项目

/// <summary>
/// 播放角色语音
/// </summary>
public void PlayVoice(AudioClip voice)
{
    
    
    voiceAudioSource.clip = voice;
    voiceAudioSource.Play();
}

/// <summary>
/// 停止角色语音
/// </summary>
public void StopVoice()
{
    
    
    voiceAudioSource.Stop();
}

13、阶段性代码

E_AudioController.cs

/// <summary>
/// Audio控制器类型枚举
/// </summary>
public enum E_AudioController
{
    
    
    BgmController,
    SoundController,
    Sound2DController,
    Sound3DController,
    BgsController,
    MsController,
    VoiceController,
}

AudioObjectPool.cs

/// <summary>
/// 获取对象
/// </summary>
/// <param name="SoundPool">对象池</param>
/// <param name="parent">父级</param>
/// <returns></returns>
public GameObject Spawn(GameObject SoundPool, Transform parent = null)
{
    
    
    GameObject go = null;
    for (int i = 0; i < SoundPool.transform.childCount; i++)
    {
    
    
        //如果对象池中有，则从对象池中取出来用。
        if (!SoundPool.transform.GetChild(i).gameObject.activeSelf)
        {
    
    
            go = SoundPool.transform.GetChild(i).gameObject;
            go.SetActive(true);
            break;
        }
    }
    //如果对象池中没有，则创建一个游戏对象。
    go = go ? go : new GameObject(SoundPool.name + "_Pool");

    if(!parent) parent = SoundPool.transform;
    go.transform.SetParent(parent);

    go.transform.localPosition = Vector3.zero;


    return go;
}

AudioManager.cs

/// <summary>

三、AudioMixer混音器的作用

在这里插入图片描述

1、Audio Mixer简单的使用

1.1、创建Audio Mixer

创建方式：创建一个Mixer文件夹——>鼠标右键——>Create——>Audio Mixer即可

1.2、新建不同的音频控制器组

master就是主音量，里面每个又相互独立，可以单独控制各模块的音量
在这里插入图片描述

1.3、配置音频控制器组

在这里插入图片描述

1.4、调整音量

在这里插入图片描述

1.5、暴露音量控制参数

在这里插入图片描述
依次按照上图操作，得到下图，修改参数
在这里插入图片描述
代码控制音量变化

public AudioMixer audioMixer; // 进行控制的Mixer变量

public void SetMasterVolume(float volume) // 控制主音量的函数
{
    
    
	// MasterVolume为我们暴露出来的Master的参数
	audioMixer.SetFloat("MasterVolume", volume);
}

2、AudioMixer和我们的音效管理器结合，控制音量

绑定混音器控制器组

bgmAudioSource.outputAudioMixerGroup = audioMixer.FindMatchingGroups("BGM")[0];

音量控制，注意重置音量，不要用audioMixer.ClearFloat，获取音量时会有所延迟

/// <summary>
/// 设置总音量
/// </summary>
/// <param name="volume">音量</param>
public void SetMasterVolume(float volume)
{
    
    
    
    if (volume > 20f || volume < -80f)
    {
    
    
        Debug.LogWarning("音量必须在20到60之间");
        return;
    }
    audioMixer.SetFloat(MatserAudioMixerVolumeName, volume);
}

/// <summary>

/// </summary>
/// <param name="volume">音量</param>
public void SetBGMVolume(float volume)
{
    
    
    // 确保 volume 在 0 到 1 之间
    if (volume < 0f || volume > 1f)
    {
    
    
        Debug.LogWarning("音量必须在 0 到 1 之间");
        return;
    }

    // 使用 Mathf.Lerp 将 volume 从 [0, 1] 映射到 [-80, 20]
    volume = Mathf.Lerp(-80f, 20f, volume);

    audioMixer.SetFloat(BGMAudioMixerVolumeName, volume);
}

/// <summary>
/// 设置音效音量
/// </summary>

public void SetSoundVolume(float volume)
{

    if (volume < 0f || volume > 1f)
    {
    
    
        Debug.LogWarning("音量必须在 0 到 1 之间");
        return;
    }

    // 使用 Mathf.Lerp 将 volume 从 [0, 1] 映射到 [-80, 20]
    volume = Mathf.Lerp(-80f, 20f, volume);
    audioMixer.SetFloat(SoundAudioMixerVolumeName, volume);
}

        return;
    }

    // 使用 Mathf.Lerp 将 volume 从 [0, 1] 映射到 [-80, 20]
    volume = Mathf.Lerp(-80f, 20f, volume);
    audioMixer.SetFloat(BGSAudioMixerVolumeName, volume);
}

/// <summary>

/// </summary>
/// <param name="volume">音量</param>
public void SetVoiceVolume(float volume)
{
    
    
    // 确保 volume 在 0 到 1 之间
    if (volume < 0f || volume > 1f)
    {
    
    
        Debug.LogWarning("音量必须在 0 到 1 之间");
        return;
    }

    // 使用 Mathf.Lerp 将 volume 从 [0, 1] 映射到 [-80, 20]
    volume = Mathf.Lerp(-80f, 20f, volume);
    audioMixer.SetFloat(VoiceAudioMixerVolumeName, volume);
}

/// <summary>
/// 重置音量
/// </summary>
public void ResetVolume()
{
    
    
    SetMasterVolume(0.8f);
   	SetBGMVolume(0.8f);
    SetSoundVolume(0.8f);
    SetBGSVolume(0.8f);
    SetVoiceVolume(0.8f);
}

调用

if (GUI.Button(new Rect(width*5, 0, width, height), "设置总音量为1", buttonStyle))
{
    
    
    AudioManager.Instance.SetMasterVolume(1);
}
if (GUI.Button(new Rect(width*5, height, width, height), "设置BGM音量为0.8", buttonStyle))
{
    
    
    AudioManager.Instance.SetBGMVolume(0.8f);
}
if (GUI.Button(new Rect(width*5, height*2, width, height), "设置音效音量为0.5", buttonStyle))
{
    
    
    AudioManager.Instance.SetSoundVolume(0.5f);
}
if (GUI.Button(new Rect(width*5, height*3, width, height), "设置环境音音量为0.2", buttonStyle))
{
    
    
    AudioManager.Instance.SetBGSVolume(0.2f);
}
if (GUI.Button(new Rect(width*5, height*4, width, height), "设置角色语音音量为0", buttonStyle))
{
    
    
    AudioManager.Instance.SetVoiceVolume(0);
}
if (GUI.Button(new Rect(width*5, height*5, width, height), "重置音量", buttonStyle))
{
    
    
    AudioManager.Instance.ResetVolume();
}

3、实现bgm背景音和BGS环境音的淡入淡出效果，使切换不会那么突兀

新增携程，控制声音淡入淡出

//声音淡入淡出
private IEnumerator FadeOutAndPlay(AudioSource audioSource, AudioClip newBGM, float duration, bool loop, string VolumeName)
{
    
    
    // 获取当前音量值
    audioMixer.GetFloat(VolumeName, out float startVolume);

    // 淡出当前 BGM
    if (audioSource.clip){
    
    
        yield return StartCoroutine(FadeAudio(-30f, duration, VolumeName)); // 将音量降到 -30dB，持续 duration 秒
    }else{
    
    
        audioMixer.SetFloat(VolumeName, -30f);
    }

    // 播放新 BGM
    audioSource.loop = loop;
    audioSource.clip = newBGM;
    audioSource.Play();

    // 淡入新 BGM
    yield return StartCoroutine(FadeAudio(startVolume, duration, VolumeName)); // 将音量升回startVolume，持续 duration 秒
}

private IEnumerator FadeAudio(float targetVolume, float duration, string VolumeName)
{
    
    
    // 获取当前音量值
    audioMixer.GetFloat(VolumeName, out float startVolume);

    float elapsed = 0f;

    while (elapsed < duration)
    {
    
    
        elapsed += Time.deltaTime;
        float newVolume = Mathf.Lerp(startVolume, targetVolume, elapsed / duration);
        audioMixer.SetFloat(VolumeName, newVolume);
        yield return CoroutineTool.WaitForFrame();
    }

    // 确保最终音量准确
    audioMixer.SetFloat(VolumeName, targetVolume);
}

修改BGM和BGS播放方法

    }
    else
    {
    
    
        bgmAudioSource.loop = loop;
        bgmAudioSource.clip = bgm;
        bgmAudioSource.Play();
    }
}

/// <summary>

/// <param name="bgs">环境音</param>
/// <param name="duration">过渡时间</param>

public void PlayBGS(AudioClip bgs, float duration = 10f, bool loop = true, bool isFade = true)
{
    
    
    if (bgs == null)
    {
    
    
        Debug.LogWarning("播放BGS失败！要播放的BGS为null");
        return;
    }

    if (isFade)
    {
    
    
        StartCoroutine(FadeOutAndPlay(bgsAudioSource, bgs, duration, loop, BGSVolumeName));
    }
    else
    {
    
    
        bgsAudioSource.loop = loop;
        bgsAudioSource.clip = bgs;
        bgsAudioSource.Play();
    }
}

4、获取音量

public float MatserVolume => GetVolume(MatserVolumeName);
public float BGMVolume => GetVolume(BGMVolumeName);
public float BGSVolume => GetVolume(BGSVolumeName);
public float SoundVolum => GetVolume(SoundVolumeName);
public float VoiceVolume => GetVolume(VoiceVolumeName);
public float GetVolume(string VolumeName){
    
    
    audioMixer.GetFloat(VolumeName, out float volume);
    Debug.Log(volume);
    // 使用 Mathf.Lerp 将 volume 从[-80, 20]映射到[0, 1]
    volume = Mathf.Lerp(0f, 1f, (volume + 80f) / 100f);;
    Debug.Log(volume);
    return volume;
}

测试调用

//获取音量
float matserVolume = AudioManager.Instance.MatserVolume;
float bGMVolume = AudioManager.Instance.BGMVolume;
float bGSVolume = AudioManager.Instance.BGSVolume;
float soundVolum = AudioManager.Instance.SoundVolum;
float voiceVolume = AudioManager.Instance.VoiceVolume;

四、制作设置音量面板

参考：【unity进阶知识10】从零手搓一个UI管理器/UI框架，自带一个提示界面，还有自带DOTween动画效果

可以和我们之前做的UI框架配合，制作一个设置音量面板

1、UI绘制

在这里插入图片描述

2、SettingsUI参考代码

public class SettingsUI : UIBase {
    
    
    void Awake(){
    
    
        OnBtnClick("bg/退出按钮", OnCloseBtn);
        OnBtnClick("bg/重置按钮", OnResetBtn);
        OnSliderChanged("bg/Volume/Master/Slide", OnSliderMasterVolume);
        OnSliderChanged("bg/Volume/BGM/Slide", OnSliderBGMVolume);
        OnSliderChanged("bg/Volume/BGS/Slide", OnSliderBGSVolume);
        OnSliderChanged("bg/Volume/Sound/Slide", OnSliderSoundVolume);
        OnSliderChanged("bg/Volume/Voice/Slide", OnSliderVoiceVolume);

        SetSliderValue();
    }

    void OnCloseBtn(){
    
    
        //关闭界面
        Close();
        //提示
        UIManager.Instance.ShowTips("关闭界面！", Color.red);
    }

    void OnResetBtn(){
    
    
        UIManager.Instance.ShowTips("重置成功！", Color.blue);
        AudioManager.Instance.ResetVolume();
        SetSliderValue();
    }

    //修改总音量
    void OnSliderMasterVolume(float value){
    
    
        AudioManager.Instance.SetMasterVolume(value);
    }

    void OnSliderBGMVolume(float value){
    
    
        AudioManager.Instance.SetBGMVolume(value);
    }
    void OnSliderBGSVolume(float value){
    
    
        AudioManager.Instance.SetBGSVolume(value);
    }
    void OnSliderSoundVolume(float value){
    
    
        AudioManager.Instance.SetSoundVolume(value);
    }
    void OnSliderVoiceVolume(float value){
    
    
        AudioManager.Instance.SetVoiceVolume(value);
    }



    void SetSliderValue(){
    
    
        transform.Find("bg/Volume/Master/Slide").GetComponent<Slider>().value = AudioManager.Instance.MatserVolume;
        transform.Find("bg/Volume/BGM/Slide").GetComponent<Slider>().value = AudioManager.Instance.BGMVolume;
        transform.Find("bg/Volume/BGS/Slide").GetComponent<Slider>().value = AudioManager.Instance.BGSVolume;
        transform.Find("bg/Volume/Sound/Slide").GetComponent<Slider>().value = AudioManager.Instance.SoundVolum;
        transform.Find("bg/Volume/Voice/Slide").GetComponent<Slider>().value = AudioManager.Instance.VoiceVolume;
    } 
}

3、打开设置面板

UIManager.Instance.ShowUI<SettingsUI>();

4、效果

设置面板
