Developed adjustable compression level support for the ZipPacker module in the godotengine/godot repository, enabling developers to explicitly control ZIP archive compression during file packaging. Designed and implemented a new API for setting and retrieving compression levels, integrating this functionality directly into the ZIP file writing process. Employed C++ for core development, leveraging Godot’s core APIs and focusing on robust file handling. Adopted a test-driven approach by adding comprehensive unit tests to validate both compressed and uncompressed archive creation. This work enhanced packaging flexibility, allowing users to balance archive size and CPU usage for more efficient cross-platform distribution workflows.
