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 ) dest = dest + '.png' data. dirname ( dest ), exist_ok = True ) # correct extension dest, ext = os. split ( '/' )) # make sure that the dir of that path exists os. read () # create dest based on original path dest = os. save ( dest ) # alternative way which keeps the original path for path, obj in env. splitext ( dest ) dest = dest + '.png' img = data. name ) # make sure that the extension is correct # you probably only want to do so with images/textures dest, ext = os. read () # create destination path dest = os. name in : # parse the object data data = obj. objects : # process specific object types if obj. load ( file_path ) # iterate over internal objects for obj in env. join ( root, file_name ) # load that file via UnityPy.load env = UnityPy. walk ( source_folder ): for file_name in files : # generate file_path file_path = os. import os import UnityPy def unpack_all_assets ( source_folder : str, destination_folder : str ): # iterate over all files in source folder for root, dirs, files in os. from UnityPy.helpers import TypeTreeHelper TypeTreeHelper. In case this happens, the usage of the C-typetree reader can be disabled by adding these two lines to your main file. The C-implementation of the typetree reader can directly crash python. Visual C++ Redistributable is required for the brotli dependency. _version_ != '1.9.6' : raise ImportError ( 'Invalid UnityPy version detected. Make sure to make a note of the used UnityPy version in your README or add a check in your code.Į.g. So in case that you don't want to actively maintain your project,

Those changes are usually limited to minor versions (x.y) and not to patch versions (x.y.z). If you're using UnityPy a commercial project,Ī donation to a charitable cause or a sponsorship of this project is expected.Īs UnityPy is still in active development breaking changes can happen.

If you need advice or if you want to talk about (game) data-mining, MonoBehaviour (and all other types that you have the typetree of).Sprite(indirectly via linked Texture2D).So far following obj types can be edited: Next to extraction, it also supports editing Unity assets.
