data-manager

You can manage game state in Phaser across scenes by using a centralized event-driven key-value store on the global registry, enabling cross-scene data propagation and reactive event handling for shared state.

Data binding for individual Phaser game objects works through per-GameObject data storage using setData and getData, triggering reactive updates via dedicated per-key change events whenever specific values are modified.

Yes, you can listen for specific data changes on a Phaser scene's data manager by subscribing to changedata-* and setdata events, allowing targeted reactive responses when individual keys are updated.

The Phaser DataManager API supports set, get, inc, toggle, merge, remove, and query operations, providing comprehensive in-game data manipulation with safe handling and dedicated per-key change events.

You can prevent unintended mutations to Phaser game state by using the DataManager's data freezing and reset mechanics, which guard against unintended modifications during gameplay and UI updates.
