我希望 能对 Game 中的 游戏音效做一个 统一的管理 ,故设计如下:
利用XML 加载 外部MP3 保存到 MySoundModel 中 ,用 SoundBaseManager.as进行统一的音乐播放管理:
代码:
mySounds.xml:
MySoundModel.as:
/** * 音乐MODEL * @author Aonaufly * */public class MySoundModel{ public var $id : int; public var $name : String; public var $url : String; public var $type : String;} MySoundVO.as:
