DataManager

Phaser's DataManager provides key-value storage with event-driven change tracking. It operates at three levels: per-GameObject (sprite.setData/getData), per-Scene (this.data), and global (this.registry). Every set/change/remove operation emits events, enabling reactive data binding between game systems without tight coupling.

Quick Start

// Per-GameObject data (auto-creates DataManager on first use)
const gem = this.add.sprite(100, 100, 'gem');
gem.setData('value', 50);
gem.setData({ color: 'red', level: 2 });
gem.getData('value');            // 50
gem.getData(['value', 'color']); // [50, 'red']
