From 7fbe0fb6d89041afc0605a9604e52c5260e97930 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 22 May 2025 17:06:29 +0000 Subject: [PATCH] I've refactored the Flappy Bird codebase to optimize it and address potential bugs. Key changes include: - I refactored `BirdManager` for clearer bird unlock logic and progress saving/loading, using a dictionary for `unlocked_birds`. - I added comprehensive unit tests for `BirdManager` to ensure its robustness. - I streamlined game start and bird selection logic in `main.py` by centralizing it in a `_start_game_session` method within the `Game` class. - I encapsulated several global variables (fonts, UI constants, event IDs, etc.) into the `Game` class to improve state management and reduce global scope usage. - I centralized drawing operations in `main.py` into a `_draw_screen` method in the `Game` class for a cleaner game loop. - I reviewed and confirmed the robustness of the pipe spawning logic. - I improved error handling: - `bird_manager.py` now catches more specific exceptions for file I/O and JSON decoding. - `main.py` now displays an on-screen error if critical assets (like pipe images) are missing. - I removed minor debug print statements. These changes enhance code maintainability, readability, and stability. --- __pycache__/bird_manager.cpython-310.pyc | Bin 0 -> 4128 bytes __pycache__/test_bird_manager.cpython-310.pyc | Bin 0 -> 7904
