unity提供了assetbunlde机制，下面介绍一种方法将指定目录下的所有文件打包成AssetBundle先说明步骤，再上代码。步骤一、选择要打包成assetbundle的目录，本案例使用assetbundle_raw步骤二、把要打包的资源或者目录都放到assetbundle_raw目录，资源可以是& &&&&&&&&&&&&&&&prefab,png,fbx,font,audio,txt等。步骤三、给assetbundle_raw目录下所有的资设置assetbundle名称，如果是目录，会递归。&& & &&&&&&&&名称格式：资源名称.资源后缀.unity3d，&&&&&&&&&&&&如果有子目录，则资源名称为：子目录/子目录/.../子目录/资源名称.资源后缀.unity3d&&&&&&&&&&&&在给这些资源设置assetbundle名称的时候会把该资源所依赖的所有资源都设置上&&&&&&&&&&&&assetbundle名称。脚本已经写好，稍后附上，这一步你只需要点击&&&&&&&&&&&&Tools-&AssetBundle-&Set Asset Bundle Names就可以。步骤四、选择assetbundle输出目录，本案例使用StreamingAssets目录。只所以要使用这个目录，主要&&&&&&&&&&&&是考虑到本地测试会比较方便，打包好的assetbundle肯定需要进行一下测试，没问题后再放到&&&&&&&&&&&&资源上，另外就是可以把StreamingAssets目录作为本地资源测试服务器，还可以打包到&&&&&&&&&&&&设备上进行测试。操作：Tools-&AssetBundle-&Build Bundles。步骤五、生成资源版本文件。步骤四执行完毕后，assetbundle已经生成，另外还会生成Manifest文件，&&&&&&&&&&&&因为assetbundle和平台相关，以平台为例，会生成android和android.manifest文件，&&&&&&&&&&&&我们需要根据android文件获取每个bundle的hash值，生成版本文件，用于热更新。废话不多&&&&&&&&&&&&说，操作：Tools-&AssetBundle-&Generate Resource
File。至此，assetbundle打包完成。特别需要注意：&&&&放到assetbundle_raw目录下的资源，互相之间不要有任何依赖关系，否则，在步骤三设置名称的阶段，被依赖的资源就会被设置两次或者多次assetbundle名称，这样它只能使用最后设置的名称。如果是这样的话，在加载assetbundle的时候，就可能出现已经加载的assetbundle被再次加载而报错。因为被加载的assetbundle在被释放前不能再次加载。所以，放到assetbundle_raw目录下的资源，互相之间不要有任何依赖关系；放到assetbundle_raw目录下的资源，互相之间不要有任何依赖关系；放到assetbundle_raw目录下的资源，互相之间不要有任何依赖关系。重要的话说三遍。另外需要注意的地方，在前面的中也提到了。要打包的资源名称不要有空格,空格在pc上支持，在android上不支持名称用小写，下划线，数字，尽量不要用大写，因为unity打包成assetbundle后的资源名称都是小写建议unity所有的资源命名的时候用小写，下划线，数字，尽量不要用大写如果用到一些插件，例如NGUI等，里面的资源，如，shader文件名称中间是有空格的，它会作为依赖资源打包成assetbundle，这样的手机上加载就可能出错。编辑器代码：using

跟我从零基础学习Unity3D开发--资源打包篇（AssetBundle）
好久没更新了，一直在加班敢项目进度。这里和关注我的博客的童鞋表示一下歉意！这里有我录的Unity3D从零开始的视频教程大家可以关注一下：/view/555 &视频会陆续的更新，需要讲什么也可以留言给我。
之前在项目中一直用的是别人以前的写的打包代码，后来项目需要需要修改以前的代码把打包的代码过了一遍，今天把自己遇到的问题和打包思路在这路写下来。
在untiy支援加载方面分为两个种类：
第一类：Resources方式加载-------我们不用打包资源，放在项目中的Resources目录下就能在代码中直接加载出来。
第二类：assetBundle方式加载-----需要我们打包资源，把每个资源打包成一个个Bundle，然后加载。
两类资源加载方式在游戏项目中都会用，Resources加载的资源一般是要求非常及时的，assetBundle加载相对要慢一些因为需要把assetBundle资源解压出来。assetBundle也是方便项目中做热更新（在游戏对外发布的过程中，我们需要替换一些资源，通过热更新的方式把资源更新出去供当前的客户端下载替换）。Assetbundle是官方推荐使用的打包方式，AssetbundleUnity（Pro）提供的资源打包策略。
打包思路：
a、打包的资源一定要放在StreamingAssets目录下因为在移动平台下只能访问这个目录
b、AssetBundle的保存后缀名可以是assetbundle或者unity3d
c、BuildAssetBundle要根据不同的平台单独打包，BuildTarget参数指定平台，如果不指定，默认的webplayer
1、准备好我们需要打包的资源
2、加载需要打包的资源
3、获取当前对象列表的所有依赖项
4、设置打包编译选项
5、开始打包
重要函数解释： Selection.objects & ---------------------------------------------------& 这个方法是用于判断在Asset目录中返回选中了哪些资源文件 AssetDatabase.GetAssetpath()-------------------------------------- 获取的是工程文件相对于Asset的路径 AssetDatabase.LoadMainAssetAtPath()---------------------------- & 加载指定路径下的资源 EditorUtility.CollectDependencies()--------------------------------- 获取当前对象列表的所有依赖项 BuildAssetBundleOptions ------------------------------------------- 打包编译选项 BuildPipeline.BuildAssetBundle() ---------------------------------- 打包函数 Path.GetFileNameWithoutExtension() ----------------------------- 获取路径下的不要扩展名的文件名 Path.ChangeExtension() -------------------------------------------- & 改变路径的文件后缀名 EditorUserBuildSettings.activeBuildTarget ----------------------- & 判断当前编译平台 & & 下面列出打包实例代码！ 实例： &
