SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Phaser games rely on events for scene lifecycle, input, loading, animations, and inter-scene communication, but remembering event names, emitter scopes, and listener cleanup rules is error-prone and causes memory leaks. ## Core Features & Use Cases - Complete Event Reference: Covers all Phaser event namespaces including Scene, Core, Input, Loader, Animations, Cameras, Sound, Tweens, Physics, Textures, GameObjects, and Time events with their string values and constants. - Listener Lifecycle Guidance: Explains on, once, off, and removeAllListeners usage, context binding, and shutdown cleanup patterns to prevent duplicate listeners on scene restarts. - Inter-Scene Communication Patterns: Documents game.events as a global bus, the registry DataManager, and direct scene access for cross-scene messaging. - Use Case: When building a Phaser scene that listens for pointer input and emits a custom player-died event, use this Skill to wire listeners with named constants and clean them up on SHUTDOWN. ## Quick Start Ask the AI to add a pointerdown listener in a Phaser scene that emits a custom event and is properly removed when the scene shuts down.

Frequently Asked Questions about events-system

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I listen for events in Phaser?▼

Use the on method on any Phaser emitter, such as this.input.on('pointerdown', handler) or this.events.on(Phaser.Scenes.Events.UPDATE, handler, this). Prefer named constants like Phaser.Input.Events.POINTER_DOWN over raw strings to avoid typos.

How do scenes communicate with each other in Phaser?▼

Scenes communicate through game.events as a global event bus, through this.registry which is a shared DataManager firing changedata events, or by directly accessing another scene with this.scene.get('SceneKey').events.emit.

Why do Phaser event listeners fire multiple times after scene restart?▼

Listeners registered with on persist across scene restarts, so each restart adds duplicates. Remove them in a SHUTDOWN handler using off with the exact same function reference and context, or use once for single-fire listeners.

What is the difference between this.events and this.game.events in Phaser?▼

this.events is the scene-level emitter firing scene lifecycle events and is cleaned up when the scene is destroyed. this.game.events is a global emitter for game-level events like blur and focus that persists across scene restarts.

How do I remove an event listener in Phaser?▼

Call off with the exact same function reference and context passed to on, for example this.input.off('pointerdown', this.onPointerDown, this). Anonymous arrow functions cannot be removed, so store a reference or use a class method.
