一般来讲如果项目是PC或Android、IOS端不会有批量Build打包这样的需求，但如果项目是WebGL端可能会遇到这样的需求：不同场景打包成不同的包体，入口是前端在页面中布局的，点击链接打开相应的程序。依次手动打包比较繁琐而且需要等待很长时间，因此写了批量Build这样的功能，下班时点击Build经历漫长的夜晚，第二天上班时包体已经都打好了。
核心API是UnityEditor.BuildPipeline类中的BuildPlayer，调用该方法传入相应参数即可实现打包，我们要做的是做一个配置文件，在其中配置打包不同包体对应的数据，包含打包的场景、名称和平台等。首先构建可序列化类：
////// 打包任务 /// [Serializable] public sealed class BuildTask { ////// 名称 /// public string ProductName; ////// 目标平台 /// public BuildTarget BuildTarget; ////// 打包路径 /// public string BuildPath; ////// 打包场景 /// public ListSceneAssets = new List (0); }
使用ScriptableObject构建配置：
////// 打包配置表 /// [CreateAssetMenu(fileName = "New Build Profile", menuName = "Build Profile")] public sealed class BuildProfile : ScriptableObject { ////// 打包任务列表 /// public ListBuildTasks = new List (0); }
有了BuildProfile后，配置打包列表，批量打包要做的就是遍历该列表依次调用BuildPipeline中的BuildPlayer方法。创建Editor类，重写BuildProfile的Inspector面板，编写打包功能，以及添加、移除打包项等菜单。
