声音管理类AudioManager

今天给大家分享下刚刚做的AudioManager

实现了以下功能：

1.同时播放一首背景音乐

2.同时播放N个音效

3.对象池管理AudioSource组件

4.背景音乐的声音淡入淡出

5.调整背景音乐的音量

6.调整音效的音量

7.本地缓存声音音量

8.切换场景不销毁

使用方法： 直接挂载到空物体上

应该是实现了大部分项目中需要的声音管理类的功能

下面为实现的代码

使用：

    AudioManager.Instance.PlayMusic(1);    AudioManager.Instance.PlaySound(11);    AudioManager.Instance.ChangeMusicVolume(0.5f);    AudioManager.Instance.ChangeSoundVolume(0.5f);
