## What it is
UnityPy is a Python library for extracting, unpacking, and editing Unity game engine asset files, based on AssetStudio. It supports reading and modifying all object types via typetree structures in their native forms.

## Use cases
- extract textures and sprites from Unity games
- unpack Unity asset bundles in Python
- edit Unity asset files programmatically
- data-mine game assets from Unity builds
- convert Unity assets like audio and meshes to standard formats
- reverse engineer Unity game resources

## When to choose
- you need to programmatically extract or edit Unity assets from Python
- you want an open-source AssetStudio alternative with scripting support
- you are doing game data-mining or modding research

## When to avoid
- you need a GUI tool for browsing Unity assets
- you need a stable API for long-term unmaintained projects, since breaking changes occur in minor versions
- you work with non-Unity game engines

## Facets
- artifact type: library
- maturity: active
- function: parser, file-system, image-processing, audio-processing, developer-tools
- domain: gaming-tools, files, developer-tools
- platform: python, windows, cross-platform
- tags: unity-assets, asset-extraction, game-data-mining, asset-editing, assetstudio, data-engineering, macos, linux
