简介： Unity 实现批量Build打包

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：

/// <summary>/// 打包任务/// </summary>[Serializable]
publicsealedclassBuildTask{
/// <summary>/// 名称/// </summary>publicstringProductName;
/// <summary>/// 目标平台/// </summary>publicBuildTargetBuildTarget;
/// <summary>/// 打包路径/// </summary>publicstringBuildPath;
/// <summary>/// 打包场景/// </summary>publicList<SceneAsset>SceneAssets=newList<SceneAsset>(0);
}

使用ScriptableObject构建配置：

/// <summary>/// 打包配置表/// </summary>[CreateAssetMenu(fileName="New Build Profile", menuName="Build Profile")]
publicsealedclassBuildProfile : ScriptableObject{
/// <summary>/// 打包任务列表/// </summary>publicList<BuildTask>BuildTasks=newList<BuildTask>(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。

[CustomEditor(typeof(BuildProfile))]
publicsealedclassBuildProfileInspector : Editor{
privatereadonlyDictionary<BuildTask, bool>foldoutMap=newDictionary<BuildTask, bool>();
privateVector2scroll=Vector2.zero;

    {

ProductName="Product Name",
BuildTarget=BuildTarget.StandaloneWindows64,
BuildPath=Directory.GetParent(Application.dataPath).FullName                };
profile.BuildTasks.Add(task);
            }
if (GUILayout.Button("展开", "ButtonMid"))
            {
