BAAH (Blue Archive Aris Helper) is a Python-based automation tool for the mobile game Blue Archive. It automates daily tasks, combat, events, and other in-game activities through image recognition, OCR, and ADB-based emulator/device control. The application features a NiceGUI-powered desktop interface for configuration and task management, with support for multiple game servers (Global, Japan, CN, Bilibili, Steam) and cross-platform deployment (Windows, macOS, Linux, Android). The architecture follows a modular task-based design where each automation task (login, combat, cafe, etc.) inherits from a base Task class defining standardized lifecycle methods (pre_condition, on_run, post_condition). Game state detection relies on template matching via a Page class, while complex automation flows are built using composable actions from the define_actions module. Configuration is managed through a hierarchical system supporting user, software, session, and storage layers with i18n and post-processing capabilities. The GUI provides reusable components for list editing, screenshot capture, and task execution monitoring. Key external dependencies include OpenCV for image processing, ONNX Runtime for OCR, NiceGUI for the web-based GUI, and ADB for device communication. The tool stores user configurations as JSON files and maintains historical data in USER_STORAGE. Self-update functionality checks multiple sources (Gitee/GitHub/mirror) for new versions.
