SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enables the design and implementation of event-driven reactive nodes within GECS, facilitating entity lifecycle management, query monitoring, and custom gameplay reactions.

Core Features & Use Cases

  • Component Lifecycle Handlers: React to components being added or removed from entities, such as spawning or cleanup actions.
  • Query State Monitors: Trigger specific callbacks when entities enter or leave certain states, supporting behaviors like targeting or status effects.
  • Custom Gameplay Events: Subscribe to user-defined events emitted within the game to trigger game logic updates or UI responses.
  • Relationship Events: Monitor changes in entity relationships, enabling dynamic targeting or hierarchy-based reactions.

Quick Start

Define observers that listen for component additions, query matches, or custom events, and implement your game logic within their callbacks to create responsive gameplay systems.

FAQPage Schema
How do I create reactive event handlers for entity lifecycle changes in GECS?

You create reactive event handlers in GECS by defining observers that listen for component additions or removals, triggering callbacks to execute spawning or cleanup actions when entity lifecycle events occur.

How do I trigger gameplay logic when entities enter or leave specific query states?

You trigger gameplay logic by setting up query state monitors that execute specific callbacks when entities match or leave query conditions, enabling reactive behaviors like targeting or status effects.

Can I monitor entity relationship changes to trigger dynamic gameplay reactions?

Yes, you can monitor entity relationship changes by configuring observers to watch relationship updates, enabling dynamic targeting or hierarchy-based reactions within your GECS workflow.

Do I need to understand the GECS observer API to implement custom gameplay events?

Yes, implementing custom gameplay events requires an understanding of the GECS observer API and proper query configurations to effectively subscribe to user-defined signals and trigger UI responses.

What is the best way to subscribe to custom gameplay signals for UI updates?

The best way to subscribe to custom gameplay signals is by defining observers that listen for user-defined events emitted within the game, triggering callbacks to execute game logic updates or UI responses.
