Unty5.x里Assetbundle的自动标记和打包

最近研究了一下assetbundle的自动标记和打包,参考了很多网上教程写了一篇代码,废话不多说,直接看代码把

using System.Collections;using System.Collections.Generic;using UnityEngine;using UnityEditor;using System.IO;public class AssetBundleEditor{    #region 自动做标记    //思路    //1.找到资源保存的文件夹    //2.遍历里面每个场景文件夹    //3.遍历场景文件夹里的所有文件系统    //4.如果访问的是文件夹:继续访问里面所有的文件系统,直到找到 文件(递归)    //5.找到文件,修改他的 assetbundle labels    //6.用 AssetImporter 类 修改名称和后缀    //7.保存对应的文件夹名和具体路径    [MenuItem("AssetBundle/Set AssetBundle Labels")]    public static void SetAssetBundleLabels()    {        //移除所有没有使用的标记        AssetDatabase.RemoveUnusedAssetBundleNames();        //1.找到资源保存的文件夹        string assetDirectory = Application.dataPath + "/Res";//"D:/WorkSpace/UnityWorkSpace/MobaClient/AssetBundles/Assets/Res";        DirectoryInfo directoryInfo = new DirectoryInfo(assetDirectory);        DirectoryInfo[] sceneDirectories = directoryInfo.GetDirectories();        //2.遍历里面每个场景文件夹        foreach (DirectoryInfo tempDirectoryInfo in sceneDirectories)        {            string sceneDirectory = assetDirectory + "/" + tempDirectoryInfo.Name;            DirectoryInfo sceneDirectoryInfo = new DirectoryInfo(sceneDirectory);            //错误检测            if (sceneDirectoryInfo == null)            {                Debug.LogError(sceneDirectory + "不存在");                return;            }            else            {                Dictionary<string, string> namePathDict = new Dictionary<string, string>();                //3.遍历场景文件夹里的所有文件系统                //D:\WorkSpace\UnityWorkSpace\MobaClient\AssetBundles\Assets\Res                //D:/WorkSpace/UnityWorkSpace/MobaClient/AssetBundles/Assets/Res                int index = sceneDirectory.LastIndexOf("/");                string sceneName = sceneDirectory.Substring(index + 1);                onSceneFileSystemInfo(sceneDirectoryInfo, sceneName, namePathDict);                onWriteConfig(sceneName, namePathDict);            }        }//end foreach        AssetDatabase.Refresh();        Debug.LogWarning("设置成功");    }//end set    /// <summary>    /// 记录配置文件    /// </summary>    private static void onWriteConfig(string sceneName, Dictionary<string, string> namePathDict)    {        string path = PathUtil.GetAssetBundleOutPath()+ "/" + sceneName  + "Record.txt";

               foreach (KeyValuePair<string, string> kv in namePathDict)                    sw.WriteLine(kv.Key + " " + kv.Value);            }        }    }    private static void onSceneFileSystemInfo(FileSystemInfo fileSystemInfo, string sceneName, Dictionary<string, string> namePathDict)    {        if (!fileSystemInfo.Exists)        {            Debug.LogError(fileSystemInfo.FullName + "不存在");

           if (fileInfo == null)            {                //代表强转失败,不是文件 就是文件夹                //4.如果访问的是文件夹:继续访问里面所有的文件系统,直到找到 文件(递归)                onSceneFileSystemInfo(tempfileInfo, sceneName, namePathDict);            }            else            {                //文件                //5.找到文件,修改他的 assetbundle labels                setLables(fileInfo, sceneName, namePathDict);            }        }    }    /// <summary>    /// 修改资源文件的 assetbundle labels    /// </summary>    /// <param name="fileInfo"></param>    /// <param name="sceneName"></param>    private static void setLables(FileInfo fileInfo, string sceneName, Dictionary<string, string> namePathDict)    {        //忽视unity自身生成的meta文件        if (fileInfo.Extension == ".meta")            return;        string bundleName = getBundleName(fileInfo, sceneName);        int index = fileInfo.FullName.IndexOf("Assets");        string assetPath = fileInfo.FullName.Substring(index);        //6.用 AssetImporter 类 修改名称和后缀        AssetImporter assetImporter = AssetImporter.GetAtPath(assetPath);        assetImporter.assetBundleName = bundleName;        if (fileInfo.Extension == ".unity")            assetImporter.assetBundleVariant = "u3d";        else            assetImporter.assetBundleVariant = "assetbundle";        //添加到字典        string folderName = "";        if (bundleName.Contains("/"))            folderName = bundleName.Split('/')[1];        else            folderName = bundleName;        string bundlePath = assetImporter.assetBundleName + "." + assetImporter.assetBundleVariant;        if (!namePathDict.ContainsKey(folderName))            namePathDict.Add(folderName, bundlePath);    }    /// <summary>    /// 获取包名    /// </summary>    private static string getBundleName(FileInfo fileInfo, string sceneName)    {        string windowPath = fileInfo.FullName;

还有一篇获取路径的

using System.Collections;using System.Collections.Generic;using UnityEngine;using System.IO;/// <summary>/// 路径/// </summary>public class PathUtil{    /// <summary>    /// 获取assetbundle的输出目录    /// </summary>    /// <returns></returns>    public static string GetAssetBundleOutPath()    {        string outPath = getPlatformPath() + "/" + getPlatformName();        if (!Directory.Exists(outPath))            Directory.CreateDirectory(outPath);        return outPath;    }    /// <summary>    /// 自动获取对应平台的路径    /// </summary>    /// <returns></returns>    private static string getPlatformPath()    {        switch (Application.platform)        {                        case RuntimePlatform.WindowsPlayer:                      case RuntimePlatform.WindowsEditor:                return Application.streamingAssetsPath;                                    case RuntimePlatform.Android:                return Application.persistentDataPath;            default:                return null;        }    }    /// <summary>    /// 获取对应平台名字    /// </summary>    /// <returns></returns>    private static string getPlatformName()    {        switch (Application.platform)        {            case RuntimePlatform.WindowsPlayer:            case RuntimePlatform.WindowsEditor:                return "Windows";            case RuntimePlatform.Android:                return "Android";            default:                return null;        }    }    /// <summary>    /// 获取www协议的路径    /// </summary>    public static string GetWWWPath()    {        switch (Application.platform)        {            case RuntimePlatform.WindowsPlayer:            case RuntimePlatform.WindowsEditor:                return "file:///"+ GetAssetBundleOutPath();            case RuntimePlatform.Android:                return "jar:file://" + GetAssetBundleOutPath();            default:                return null;        }    }}
