效果

自动维护一个 AudioSource的池子

如果超过了池子的峰值 池子会生成一个新的AudioSource对象来进行扩容

• 支持2D音效调用方式 public void PlaySound( string url, float volume = 1.0f, bool loop = false )
• 支持2D音乐调用方式 public void PlayMusic( string url, float volume = 1.0f, bool loop = true )
• 支持3D音效调用方式 public void PlaySoundAtPoint( string url, Vector3 position, float volume = 1f )

食用方式

更改这块的加载 用你们自己框架里的加载方式 或者 走 Resource.Load

源码
