有时加载的AssetBundle文件会出现异常，比如引用丢失之类的问题，就需要我们获取到当前AssetBundle文件中的相关信息。使用Unity内置的工具就可以获取到相关信息。
-
工具目录位置
- mac
/Applications/Unity/Unity.app/Contents/Tools- windows
C:\Program Files\Unity\Editor\Data\Tools -
相关工具
-
WebExtract
将AssetBundle中的数据信息解析为二进制文件// 导出到当前路径的子目录中 ./WebExtract assetbundlefile -
binary2text
将上一步中的二进制文件解析为记录了引用等信息的文本文件./binary2text binarydataPath outputPath -
注意
- 直接运行以上命令可以查看所需参数
- 工具的unity版本要与生成assetbundle的unity版本一致
-
-
最终得到的文本文件中包含了
- 资源类型及数据结构
- AssetBundleName
- 引用资源
- 被引用资源
- 其它信息
范例
一个材质matCube.mat通过依赖打包后，再被解析出的文件如下：
