SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill resolves common issues with event management in Phaser 4, such as memory leaks from unremoved listeners, incorrect context binding, and confusion between scene-level and global game events.

Core Features & Use Cases

Event Lifecycle Management: Provides clear patterns for adding and removing listeners to prevent memory leaks during scene restarts.
Inter-Scene Communication: Demonstrates how to use the game event bus and registry for data sharing between scenes.
Use Case: When building a complex game, use this skill to safely manage input events on sprites and global game state changes like browser focus loss, ensuring all listeners are cleaned up during scene shutdown.

Quick Start

Use the events-system skill to implement a safe event listener in your scene that automatically cleans itself up during the shutdown phase.

FAQPage Schema

How do I prevent memory leaks from unremoved Phaser 4 event listeners?▼

Prevent Phaser 4 memory leaks by implementing clear event lifecycle management patterns that ensure all listeners are properly removed during scene restarts and shutdown phases.

What is the best way to share data between Phaser 4 scenes?▼

Share data between Phaser 4 scenes by using the global game event bus and registry to facilitate inter-scene communication. This event-driven architecture pattern safely manages data sharing across different game instances and interactive objects.

How do I safely manage sprite input events and global game state changes in Phaser?▼

Safely manage sprite input events and global state changes by registering EventEmitter listeners that automatically clean themselves up during the scene shutdown phase. This prevents context binding issues and ensures listeners are destroyed correctly.

Does this event-driven architecture pattern handle browser focus loss in Phaser games?▼

Yes, the event-driven architecture pattern handles browser focus loss by registering global game state change events. It ensures these listeners are safely managed and cleaned up during scene shutdown to maintain robust memory management.

When should I use scene-level versus global game events in Phaser 4?▼

Use scene-level events for localized interactive game object logic and global game events for cross-scene data sharing via the registry. The event-driven architecture clarifies this distinction to prevent incorrect context binding and memory leaks.

Why do my Phaser 4 game objects retain listeners after a scene restart?▼

Game objects retain listeners after a scene restart due to incorrect context binding and missing cleanup procedures. Implement proper event lifecycle management to remove listeners during the shutdown phase and prevent memory leaks.
