The code for the drop-off condition within the Overcooked simulator's counters module has been updated. The updated condition now checks not only if the item can be combined or matches the dispensing item's name but also checks if the undo dispenser pickup flag is true.

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.

The code now includes a new hook called 'drop_off_on_cooking_equipment'. This hook is used to track and score instances of players dropping off items on the cooking equipment in the Overcooked game simulator. This enhancement will allow for more detailed game simulations and scoring capabilities.

The scoring system and order management have been significantly updated. The score calculation has been moved out from 'OrderManager' to external 'ScoreViaHooks' class which works via hooks. The order management updates include separating scoring from orders and removing unused functions. Changes in the configuration file and other related files updated to accommodate these modifications.

This update introduces comprehensive hook management, improved environment setup functions, and a new class for logging and recording simulations. The enhanced hook management ensures better callback registration and tracing of specific simulation events. Extra setup functions allow more flexibility in setting parameters from the environment config. The new logging and recording class makes it easier to capture simulation data in a structured format for analysis. Various minor fixes and code refactoring are also included.

Added the definition and interactions for game effects and tools. The effect type was introduced to influence the player's interactive abilities or alter item's attributes. The tool type extends the player's interactive abilities. It also includes the part related to fire and fire extinguisher for more realistic simulation.

The random module is replaced with random instance across multiple classes within 'overcooked_simulator' to make the randomness in the Overcooked simulator controllable. The 'random' instance is initialised with a seed in 'overcooked_environment' and then passed to the classes that require randomness. This improves reproducibility of experiments, as the randomness can be controlled by the seed value.

Added a Hooks class to monitor events related to player actions, item interactions, and state changes in the game environment. A hook triggers a corresponding event when a specific action takes place, such as a player picking up an item or a game state changing. This feature will make debugging easier and provide valuable insights during gameplay.

The changes include improving the wording in readme files, from 'Python 3.10 or higher' to 'Python 3

Documentation has been updated to provide better clarity on the layout and equipment configuration. The README file now includes information on defining counter mappings in the Environment config. The code examples in comments within the counters.py file have also been reformatted and updated, specifically those related to defining equipment types and dispenser characters. The additional change includes an expanded section in the __init__.py file on environment and item configuration.

The code changes include renaming the 'category' field from "Cooking Equipment" to "ItemCookingEquipment" in sample_state.json. The documentation has also been updated with more detailed explanations on how the system works, including how to install and use it. A few function signatures were changed and additional explanation comments were included in the counters.py and utils.py files for better code clarity.

The updates include adding docstrings and type hinting to several classes and methods in multiple Python files. This commit also includes fixes for inconsistent code formatting and minor bugs. The docstrings provide essential details about the classes and methods, improving readability and understanding for other developers. Furthermore, the added type hinting will enable better IDE assistance, static analysis, and clarity on expected input and output types. Lastly, the code formatting fixes and bug fixes enhance the overall code quality and maintainability.

This update introduces a penalty computation for items that the player puts into the trash in the Overcooked simulator. A new function has been added onto the Order class to calculate this penalty, and the Trashcan class has been updated to use this new function whenever an item is dropped off. This change helps to further emulate real gameplay mechanics.

The `overcooked_environment.py` file has been significantly refactored to streamline handling of counter setup. Post counter setup responsibilities have been shifted to the `CounterFactory` class. A utility function, `get_closest`, has been introduced in `utils.py` to determine the closest counter and is used in multiple classes. Minor updates are also made across several other classes for optimization and clarity. The 'other' score in `environment_config.yaml` has been changed from 0 to 20.

This commit simplifies the overcooked environment by refactoring the way counters are created and managed. A new CounterFactory class is introduced, offloading logic from the environment class. In addition, the symbol to character mapping and other environment-related configurations are moved to a separate YAML file. The .gitignore file is also updated to ignore the 'playground' directory. Making these changes enhances code maintainability and readability.

The CookingCounter is now included in the list of counters for which we calculate progress. Additionally, if a counter type is not defined in the configuration, a ValueError will be raised. Unnecessary imports were also removed from 'overcooked_gui.py', and a 'to_dict' method was added in 'counters.py'. Fixing errors from merge.

The update introduces a new function `get_json_state()` in overcooked_environment.py that exports the current game state in JSON format. Changes were made to player.py, counters.py, and game_items.py to include an additional `to_dict()` function which represents their current status as a dictionary. This commit also includes minor naming changes, such as renaming `beginning_time` to `start_time`.

Counters get an assigned orientation. They are oriented towards the next free tile, if more exist then the one is selected which looks to the kitchen center the most.

The transition implementation for items in the simulator has been updated. This refactoring introduces the filter_item_info function, replacing the previous verbose, repeating pattern with filter_item_info method calls in the overcooked_environment.py module. This makes the code more efficient and readable. Test adjustments and additional type hints were also included.

Convert Stove to abstract "CookingCounter". Added item info and visualization for pizza and fish and chips meals including their ingredients and intermediate steps and cooking equipments and counters.
Implemented accepting_not_ordered_meals func
