一般來(lái)講如果項(xiàng)目是PC或Android、IOS端不會(huì)有批量Build打包這樣的需求，但如果項(xiàng)目是WebGL端可能會(huì)遇到這樣的需求。本文主要為大家介紹Unity中如何實(shí)現(xiàn)Build批量打包的，需要的朋友可以參考一下

一般來(lái)講如果項(xiàng)目是PC或Android、IOS端不會(huì)有批量Build打包這樣的需求，但如果項(xiàng)目是WebGL端可能會(huì)遇到這樣的需求：不同場(chǎng)景打包成不同的包體，入口是前端在頁(yè)面中布局的，點(diǎn)擊鏈接打開(kāi)相應(yīng)的程序。依次手動(dòng)打包比較繁瑣而且需要等待很長(zhǎng)時(shí)間，因此寫(xiě)了批量Build這樣的功能，下班時(shí)點(diǎn)擊Build經(jīng)歷漫長(zhǎng)的夜晚，第二天上班時(shí)包體已經(jīng)都打好了。

核心API是UnityEditor.BuildPipeline類(lèi)中的BuildPlayer，調(diào)用該方法傳入相應(yīng)參數(shù)即可實(shí)現(xiàn)打包，我們要做的是做一個(gè)配置文件，在其中配置打包不同包體對(duì)應(yīng)的數(shù)據(jù)，包含打包的場(chǎng)景、名稱(chēng)和平臺(tái)等。首先構(gòu)建可序列化類(lèi)：

/// <summary>
/// 打包任務(wù)
/// </summary>
[Serializable]
public sealed class BuildTask
{
    /// <summary>
    /// 名稱(chēng)
    /// </summary>
    public string ProductName;
    /// <summary>
    /// 目標(biāo)平臺(tái)
    /// </summary>
    public BuildTarget BuildTarget;
    /// <summary>
    /// 打包路徑
    /// </summary>
    public string BuildPath;
    /// <summary>
    /// 打包場(chǎng)景
    /// </summary>
    public List<SceneAsset> SceneAssets = new List<SceneAsset>(0);
}

使用ScriptableObject構(gòu)建配置：

/// <summary>
/// 打包配置表
/// </summary>
[CreateAssetMenu(fileName = "New Build Profile", menuName = "Build Profile")]
public sealed class BuildProfile : ScriptableObject
{
    /// <summary>
    /// 打包任務(wù)列表
    /// </summary>
    public List<BuildTask> BuildTasks = new List<BuildTask>(0);
}

有了BuildProfile后，配置打包列表，批量打包要做的就是遍歷該列表依次調(diào)用BuildPipeline中的BuildPlayer方法。創(chuàng)建Editor類(lèi)，重寫(xiě)B(tài)uildProfile的Inspector面板，編寫(xiě)打包功能，以及添加、移除打包項(xiàng)等菜單。

[CustomEditor(typeof(BuildProfile))]
public sealed class BuildProfileInspector : Editor
{
    private readonly Dictionary<BuildTask, bool> foldoutMap = new Dictionary<BuildTask, bool>();
    private Vector2 scroll = Vector2.zero;
    private BuildProfile profile;
 
    private void OnEnable()
    {
        profile = target as BuildProfile;
    }
    public override void OnInspectorGUI()

                var task = new BuildTask()
                {
                    ProductName = "Product Name",
                    BuildTarget = BuildTarget.StandaloneWindows64,
                    BuildPath = Directory.GetParent(Application.dataPath).FullName
                };
                profile.BuildTasks.Add(task);
            }
