UnityPy can detect if the file is a WebFile, BundleFile, Asset, or APK. a bytes object - will be loaded into a stream.a stream - e.g., io.BytesIO, file stream.a folder path - loads all files in that folder (bad idea for folders with a lot of files).a file path - apk files can be loaded as well.Important Classes EnvironmentĮnvironment loads and parses the given files. To enable encryption simply use t_assetbundle_decrypt_key(key), with key being the value that the game that loads the budles passes to AssetBundle.SetAssetBundleDecryptKey. As it's a feature of Unity itself, and not a game specific protection, it is included in UnityPy as well. The chinese version of Unity has its own inbuild option to encrypt AssetBundles/BundleFiles. Setting the decryption key for Unity CN's AssetBundle encryption It can also be used as a general template or as an importable tool. People with slightly advanced python skills should look at UnityPy/tools/extractor.py for a more advanced example. You probably have to read Important ClassesĪnd Important Object Types to understand how it works. splitext( dest)ĭest = dest + '.png' data. # make sure that the dir of that path exists os.

# create dest based on original path dest = os. # alternative way which keeps the original path for path, obj in env. splitext( dest)ĭest = dest + '.png' img = data. # make sure that the extension is correct # you probably only want to do so with images/textures dest, ext = os. # iterate over internal objects for obj in env. # load that file via UnityPy.load env = UnityPy. # iterate over all files in source folder for root, dirs, files in os.
