Games often require some kind of save and load system to allow the player to resume their progress from where they left off. The “Memento Pattern” is a perfect fit for this kind of system. In this article, we will discuss how to use the “Memento Pattern” in Golang to implement a load and save system for games.
Components of the Load and Save System
The “Memento Pattern” consists of three components: Originator, Memento, and Caretaker. In the context of the load and save system, we can define them as follows:
- Originator: This is the object whose state needs to be saved and restored. In the case of a game, it could be the player’s character, the game world or any other object that needs to be saved and restored.
- Memento: This represents the saved state of the Originator. In the case of a game, it could be a file that contains the player’s progress or the state of the game world.
- Caretaker: This is responsible for storing and retrieving the Memento. In the case of a game, it could be a save file manager that stores and retrieves the player’s progress or the state of the game world.
Implementation
Let’s implement the load and save system for a game using the “Memento Pattern” in Golang.
