前段时间说了AssetBundle打包，先设置AssetLabels,再执行打包，但是这样有个弊端就是所有设置了AssetLabels的资源都会打包，这次说说不设置AssetLabels，该如何打包AssetBundle
BuildPipeline.BuildAssetBundles() 这个函数，有多个重载，一个不用AssetBundleBuild数组，一个需要，如果设置了AssetLabels,那么这时候是不需要的，如果没有设置，那么我们就可以打包自定义项，
AssetBundleBuild assetBundleBuild = new AssetBundleBuild(); 我们可以new 出来一个 AssetBundleBuild ，在这里指定他的 assetBundleName 和 assetBundleVariant ，也就是前面提到的AssetLabels,
同时还要指出此资源所在地址 assetBundleBuild.assetNames = new string[] { path }; 并将所有的 AssetBundleBuild 做为数组返回，填入 BuildPipeline.BuildAssetBundles() 所需要的参数中；
详见代码
static List<AssetBundleBuild> listassets = new List<AssetBundleBuild>(); //第二种打包方式用 static List<DirectoryInfo> listfileinfo = new List<DirectoryInfo>(); static bool isover = false; //是否检查完成，可以打包 public static bool GetState() { return isover; } public static AssetBundleBuild[] GetAssetBundleBuilds() { return listassets.ToArray(); } public static void SetAssetBundleBuilds() { UnityEngine.Object obj = Selection.activeObject; //选中的物体 string path = AssetDatabase.GetAssetPath(obj);//选中的文件夹 //目录结构 Assets/Resources 没有Application.datapath SearchFileAssetBundleBuild(path); } public static void SearchFileAssetBundleBuild(string path) //是文件，继续向下 { DirectoryInfo directory = new DirectoryInfo(@path); FileSystemInfo[] fileSystemInfos = directory.GetFileSystemInfos(); listfileinfo.Clear(); foreach (var item in fileSystemInfos) { int idx = item.ToString().LastIndexOf(@"\"); string name = item.ToString().Substring(idx + 1); if ((item as DirectoryInfo) != null) listfileinfo.Add(item as DirectoryInfo); if (!name.Contains(".meta")) { CheckFileOrDirectoryReturnBundleName(item, path + "/" + name); } } if (listfileinfo.Count == 0) isover = true; else { Debug.LogError(listfileinfo.Count); } } public static string CheckFileOrDirectoryReturnBundleName(FileSystemInfo fileSystemInfo, string path) //判断是文件还是文件夹 { FileInfo fileInfo = fileSystemInfo as FileInfo; if (fileInfo != null) { string[] strs = path.Split('.'); string[] dictors = strs[0].Split('/'); string name = ""; for (int i = 1; i < dictors.Length; i++) { if (i < dictors.Length - 1) { name += dictors[i] + "/"; } else { name += dictors[i]; } } AssetBundleBuild assetBundleBuild = new AssetBundleBuild(); assetBundleBuild.assetBundleName = name; assetBundleBuild.assetBundleVariant = "bytes"; assetBundleBuild.assetNames = new string[] { path }; listassets.Add(assetBundleBuild); return name; } else { SearchFileAssetBundleBuild(path); return null; } }
然后在这里调用
注意，因为文件夹下还可能有文件夹，我们要等所有资源遍历完成，再打包，所以用了一个死循环
[MenuItem("Tools/打包选中文件夹下所有项目")] public static void BundSelectionAssets() { BuilderAssetsBunlds.SetAssetBundleBuilds(); while (true) { if (BuilderAssetsBunlds.GetState()) break; else Debug.LogError("等待....."); } BuildPipeline.BuildAssetBundles(BuilderAssetsBunlds.GetOutAssetsDirecotion(), BuilderAssetsBunlds.GetAssetBundleBuilds(), BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows); }
