Phaser 4 Core

Set up the foundation of a Phaser game: the Game config, the Scene lifecycle, asset loading, cameras, and passing data between scenes. Targets Phaser 4.2 for new projects; keep an existing Phaser 3.90 project on its pinned major unless the user explicitly asks for a migration.

When to use

• Use when starting a Phaser game, wiring the Phaser.Game config, structuring Scenes, loading assets in preload, or fixing scene transitions and shared state.
• Use when the project has phaser in package.json or import Phaser from 'phaser', and code uses preload()/create()/update().

When not to use: movement, velocity, colliders, gravity, or overlap → use phaser-arcade-physics. Complex rigid-body simulation uses Matter physics (a separate concern). For cross-engine save/load patterns use save-systems.
