Class: SaveLoadManager

Source: core/SaveLoadManager.js, line 15

The SaveLoadManager is responsible for persisting and retrieving game state, allowing players to save their progress and resume later. It works by coordinating with various parts of the game through a data provider system. Different managers or systems (e.g., SceneManager for current scene, EntityManager for player state, InventoryManager) can register as data providers to contribute their specific data to a save file and to restore their state when a game is loaded.

It typically abstracts the underlying storage mechanism (like browser localStorage or IndexedDB) and manages save "slots."

Methods

registerDataProvider(uniqueKey, provider)

Registers an object (a "data provider") that can supply data to be saved and can restore its state from loaded data. Each provider is associated with a uniqueKey to namespace its data within the save file.

A data provider object should typically implement two methods:

• getSaveData(): object - Called during a save operation. Should return a serializable object representing the provider's current state.
• loadSaveData(data: object): void - Called during a load operation. Receives the data previously saved under its uniqueKey and should restore its state accordingly.

Parameters:

Name	Type	Description
uniqueKey	string	A unique string key to identify this provider's data (e.g., "playerStats", "worldState").
provider	object	The data provider object, which must implement getSaveData() and loadSaveData(data) methods.

Example:

// Example PlayerStats provider
const playerStatsProvider = {
  currentHealth: 100,
  currentScore: 0,
  getSaveData() {
    return { health: this.currentHealth, score: this.currentScore }
  },
  loadSaveData(data) {
    this.currentHealth = data.health || 100
    this.currentScore = data.score || 0
  },
}
