UNITY3D音频管理器

简介:在unity3d中创建公用的音频管理器,实现音频播放,并根据游戏设置中的音频开关控制音乐及音效播放

在unity3d中给gameObject添加AudioSource组件即可实现音频播放功能,但不利于统一管理,尤其是当场景中物件较多时,很难逐一开启或者关闭

最近的项目中需要可设置音乐与音效开关,为了方便统一管理自己写了一个音频管理器,主要用于以下功能:

1.将音效进行分类,每一类使用一个公用的音效播放器,统一管理场景中的音乐\音效,避免为每个物件重复添加AudioSource组件

2.避免多个2D音效同时播放,造成音效混杂刺耳

3.方便在游戏设置中对音乐/音效进行统一开关处理

4.避免因物件被销毁或禁止时造成附带音效不能正常播放

代码如下,兹以备份
