}

2.具体用法

提前说明一下，音频文件是放在Resources/AudioClips/ 目录下，可以将一开始的

LoadAudioResources函数公开就能传入深层路径。

1. 基本功能使用

// 播放普通音效
AudioManager.Instance.PlaySFX("ButtonClick");// 播放全局音效
AudioManager.Instance.PlayGlobalSFX("Notification");// 播放背景音乐（自动创建Main通道）
AudioManager.Instance.PlayMusic("Main", "BackgroundMusic");// 播放战斗音乐（自动创建Battle通道）
AudioManager.Instance.PlayMusic("Battle", "BattleTheme", 0.8f);// 暂停和恢复音乐
AudioManager.Instance.PauseMusic("Main");
AudioManager.Instance.ResumeMusic("Main");// 停止所有音频
AudioManager.Instance.StopAllAudio();

2. 音量控制

2.1代码在调用时控制当次音效音量大小

// 设置主音量（影响所有音效和音乐）
AudioManager.Instance.SetMasterVolume(0.7f);// 设置特定音乐通道音量
AudioManager.Instance.SetChannelVolume("Main", 0.5f);// 淡入淡出主音量
StartCoroutine(AudioManager.Instance.FadeMasterVolume(0f, 2f, () => {Debug.Log("音量淡出完成");
}));// 淡入淡出特定通道音量
StartCoroutine(AudioManager.Instance.FadeChannel("Battle", 0f, 1.5f));

2.2使用Slider控制音量

2.2.1主音量控制

public Slider masterVolumeSlider;private void Start()
{masterVolumeSlider.value = AudioManager.Instance.GetMasterVolume();masterVolumeSlider.onValueChanged.AddListener(SetMasterVolume);
}private void SetMasterVolume(float volume)
{AudioManager.Instance.SetMasterVolume(volume);
}

2.2.2音乐通道音量控制

public Slider musicVolumeSlider;private void Start()
{musicVolumeSlider.value = AudioManager.Instance.GetChannelVolume("Main");musicVolumeSlider.onValueChanged.AddListener(SetMusicVolume);
}private void SetMusicVolume(float volume)
{AudioManager.Instance.SetChannelVolume("Main", volume);
}

没啥好多的了，直接用就行了。

下面随便写点吧
