This Unity project demonstrates the Memento Design Pattern. The Memento pattern is used to capture and restore the state of an object without exposing its internal structure. This is a useful pattern for implementing undo/redo functionality in applications.
In this example, the project manages the state of a game character using the Memento pattern. The project includes:
- Caretaker: Manages the storage and retrieval of Mementos.
- Originator: Creates and restores game states.
- Memento: Stores the state of the game.
- GameManager: Handles game state changes and interacts with the UI.
- State Saving: Saves the current state of the game character.
- Undo/Redo Functionality: Allows reverting to previous states or reapplying undone states.
- UI Update: Displays the character's score and health using TextMeshPro.
The Caretaker class is responsible for storing and managing the list of Mementos. It provides methods to add, retrieve, and manage the history of states.
The Originator class represents the game character and provides methods to save and restore its state. It interacts with the Memento class to manage game state.
The Memento class holds the state of the game character in JSON format. This class is used to save and restore states.
The GameManager class manages user input and game state changes. It handles saving, undoing, and redoing game states and updates the UI.
