The random parameter in OrderManager's initialization process under cooperative_cuisine/environment.py has been updated. Instead of using an existing random instance, a new one is now created using a specified seed. This allows for more controlled randomness within the system operation.

Added type hints and docstrings throughout the project, notably in the effects, orders, study server, and game server modules. These additions provide better understanding and ease in navigating through the codebase. Minor code reorganization and syntax optimization were also performed.

The code now contains a new hook named "additional_state_update" and accommodates accepting additional state content. This functionality is used to better manage player readiness states in the game_server module and includes updates to the get_state and get_json_state methods in the environment module. New changes also impact the environment configuration files.

The main changes include enhancing methods in cooperative_cuisine/hooks.py, cooperative_cuisine/counters.py, and cooperative_cuisine/environment.py, and updating hooks. These changes greatly improve the handling of hooks and calls, provide explicit arguments for actions, and add more comprehensive documentation. This leads to better logging and debugging, higher code readability, and improved overall code structure in the cooperative_cuisine backend.

This commit refactors the setup of recorders and hooks in several configuration files. It simplifies the YAML structure, renames "extra_setup_functions" to "hook_callbacks", and replaces "log_path" with "record_path". This makes the configurations cleaner and more intuitive. The update also removes the "func" and "kwargs" in the extra setup functions. Now only hooks are registered. This change should not affect functionality, because until now only hooks were registered as extra setup functions.

Various changes have been made in the codebase to improve readability and maintainability. Type hints have been added to the functions and variables for better understanding of the datatypes. Refactoring of some code segments has also been done to make the code more concise and readable. The 'EffectType', 'ItemType' enumerations have been enriched with docstrings for better understanding of the enums. Certain classes have been updated to better follow the single responsibility principle.

The 'player_config' dictionary is replaced with the PlayerConfig class to provide type-checking and improve readability. This change is applied across different files in the 'cooperative_cuisine' module. Additionally, this commit improves type hints for several variables and parameters to assist with code interpretation and potential error prevention.

Docstrings across classes and functions in different modules have been adjusted for consistency, specifically in how Return and Raise explanations are formatted. This makes the code more readable and uniform. Additionally, the environment name in 'environment.py' has been updated from "overcooked_sim" to "cooperative_cuisine_1".

Added docstrings to constructors of several classes in various modules to improve code readability and maintainability. Also, explicit type hints were provided for the fields in these classes aiding in better understanding of the data types used across the codebase.

The classes across several files have been modified to improve clarity, provide better comments, and refine attribute representations. This commit involves refactoring the item, effect, and player classes to include more detailed descriptions and user-friendly outputs. The change also simplifies some methods and eliminates redundancies for cleaner and more efficient code.

The PAUSED variable, which was unused, has been removed from the codebase to improve readability. Docstrings were added to multiple existing methods and instance variables in the environment.py file for better understanding of their functionalities. This change will make it easier for developers to understand the purpose and usage of the various methods and variables, ultimately smoothing the development process.

The ActionType.PUT has been replaced with ActionType.PICK_UP_DROP across all instances in the codebase. This change aligns the action name with its actual function, making the action more intuitive and the code easier to understand. This update also includes minor modifications in comments and function arguments to reflect the new action name.

Enhanced overall code clarity by adding and revising detailed comments, docstrings, and typespecs in various Python modules. Significant changes include refining functionality of effect management in 'effects.py', modifications to use of 'numpy' arrays and functions in 'movement.py', as well as adjustments to handling hooks. Additionally, minor updates in 'configs/study/level1/level1_config.yaml' and 'counter_factory.py' were made.

The updates address issues with empty meal lists during order creation. When no meals are available, no orders will be created, returning empty lists instead. Furthermore, the mandatory meal assertion in the environment's validate_environment method has been commented out. The meal list in the level1 config has been updated to only include 'Burger'.

The 'recipes.py' module is renamed to 'validation.py' and the 'RecipeValidation' class is renamed to 'Validation'. The code is refactored to use f-strings for better readability. Graph generation has also been improved by simplifying the way edges are added and returning information as a dictionary. An unnecessary png file generation has been removed. Changes have been made where these classes are imported and used.

The module 'game_items' was renamed to 'items'. Every reference to this module across different source code files was consequently updated to reflect this change.

The EffectManager class along with related effects have been moved to a newly created effects.py module. Also, instead of importing from cooperative_cuisine.effect_manager, the rest of the code now imports from cooperative_cuisine.effects. This is mainly to improve the project structure and to clarify the code organization, and avoid circular import issues.

Action, ActionType, and InterActionData classes have been moved from the environment module into a separate file named action.py. All imports have been adjusted to reflect this change. This provides a clearer structure and improves modularity in the code, as all action related classes and enums are now organized in a single module.

The 'all_players_ready' field was moved from 'state_representation.py' to 'game_server.py'. Instead of being part of the initial state of the game, it's now part of the server environment, making it easier to keep track of the readiness of all players. Additionally, the game configuration in 'study_config.yaml' was updated to accommodate one player instead of two and no bots.

Made updates across multiple files targeting the usage and setting of configuration files. Several path settings have been altered, and the logic in the study server has been revised. Changes were also made in the file imports and other operations related to configurations and paths. Additionally, a validation check is added to warn if a player with the same name already exists in the environment.

The configurations for study level and game layout have been updated to accommodate new requirements. Additionally, a RecipeValidation class has been created to handle recipe graphs, which is now being utilized in both the drawing and game_server files. This is instead of the previous more scattered approach of handling such graphs within other classes or standalone functions. These changes make the code more organized and efficient.

This commit introduces a new Movement class which handles player movements, collisions, and interactions with counters in the 'cooperative_cuisine' environment. The commit also includes necessary changes to related configurations and adjustments in the 'environment.py' and 'player.py' files to accommodate the introduction of this new class. This encapsulation enhances readability, promotes code organization, and adheres to the principle of Single Responsibility.

Meal configurations in the level 1 configuration file are updated, swapping out the previous meals with new ones. Player name has been added as a parameter to the pick_up and drop_off methods in player.py and counters.py. This allows for better tracking of the actions of individual players, which can be useful in cooperative environments where player accountability is imperative. Additionally, served meals now also log the serving player's name, providing additional context during gameplay and post-game analysis.

The 'order.py' module has been renamed to 'orders.py' for consistency and clarity. All references to this file within the code base, including import statements and comments, have been updated to reflect this change. A safer and more coherent codebase enhances readability and maintainability.

All instances of 'overcooked_simulator' have been replaced with 'cooperative_cuisine'. This includes changes in file paths, imports, and script names. The necessary adjustments to reflect this rename have also been made in the documentation, setup files, test scripts, and CI/CD configuration.

The commit introduces an option that allows dispensers in the Overcooked simulator to undo pickups of items in case of errors. This new setting, `undo_dispenser_pickup`, is now included in the `game` section of the environment configuration. Both the counter factory and dispenser have been updated to accommodate these changes.
