Unity：如何根据AssetBundle将AssetBundle构建到单独的目录中

我的项目包含多个AssetBundle，我希望能够单击编辑器中的按钮 builds all AssetBundles out into their own appropriately named folders .

换句话说，给定AssetBundles名为“A”和“B”，输出将是两个文件夹，其中“A”包含标记为包含在“A”中的内置捆绑资产，同样类似于“B”的类似文件夹 .

我在某种程度上熟悉了 AssetBundleBuild 和 BuildPipeline 类 .

这导致我产生以下脚本（见下文） .

我觉得我非常接近，因为我有一个项目中所有资产包的列表，为它们设置目录，并试图构建它们 . 问题是我收到以下错误：

Manifest AssetBundle名称“example_bundle_name”与用户预定义的AssetBundle名称冲突 .

我需要做些什么来完成这项工作？

public class BuildAssetBundles : MonoBehaviour
{
    private const string AssetBundleRootDirectory = "Assets/BuiltAssetBundles";
    private const BuildTarget BuildTarget = UnityEditor.BuildTarget.StandaloneWindows;

    [MenuItem("Build Asset Bundles/Build All Asset Bundles")]
    public static void BuildBundlesIntoDirectories()
    {
        Debug.Log("Asset bundle building started...");
        // Get all assets

        var assets = AssetDatabase.GetAllAssetPaths().ToArray();

        List<AssetBundleBuild> assetBundleBuilds = new List<AssetBundleBuild>();
        HashSet<string> processedBundles = new HashSet<string>();

        // Get asset bundle names from selection
        foreach (var o in assets)
        {
            var assetPath = o;
            var importer = AssetImporter.GetAtPath(assetPath);

            if (importer == null)
            {
                continue;
            }

            // Get asset bundle name & variant
            var assetBundleName = importer.assetBundleName;
            var assetBundleVariant = importer.assetBundleVariant;
            var assetBundleFullName = string.IsNullOrEmpty(assetBundleVariant) ? assetBundleName : assetBundleName + "." + assetBundleVariant;

            // Only process assetBundleFullName once. No need to add it again.
            if (processedBundles.Contains(assetBundleFullName))
            {
                continue;
            }

            processedBundles.Add(assetBundleFullName);

            AssetBundleBuild build = new AssetBundleBuild();

            build.assetBundleName = assetBundleName;
            build.assetBundleVariant = assetBundleVariant;
            build.assetNames = AssetDatabase.GetAssetPathsFromAssetBundle(assetBundleFullName);

            assetBundleBuilds.Add(build);
        }

        foreach (var assetBundle in assetBundleBuilds.ToArray())
        {
            if(!String.IsNullOrWhiteSpace(assetBundle.assetBundleName))
                BuildAnAssetBundle(assetBundle);
        }
        Debug.Log("Asset bundle building finished.");

    }

    static void BuildAnAssetBundle(AssetBundleBuild assetBundleToBuild)
    {
        // Put the bundles in a folder within the Assets directory.
        string assetBundleOutputDirectory = Path.Combine(AssetBundleRootDirectory, assetBundleToBuild.assetBundleName);
        if (string.IsNullOrWhiteSpace(assetBundleToBuild.assetBundleVariant))
        {
            Path.Combine(assetBundleOutputDirectory, assetBundleToBuild.assetBundleVariant);
        }

        if(!Directory.Exists(assetBundleOutputDirectory))
            Directory.CreateDirectory(assetBundleOutputDirectory);


        try
        {
            BuildPipeline.BuildAssetBundles(assetBundleOutputDirectory, new AssetBundleBuild[]{assetBundleToBuild}, BuildAssetBundleOptions.None, BuildTarget);
        }
        catch (Exception e)
        {
            Debug.Log(e);
        }
    }
}

非常感谢您的帮助和建议 .

该错误似乎意味着我的方法略有不正确，可能在设置AssetBundleBuild时，它正在制作一个重复的资产包，其中包含具有相同名称的原始内容 .
