Overview

WCGASRegenerationSubsystem is a Game Instance Subsystem that generates and manages runtime Gameplay Effects for automatic attribute regeneration and degeneration in the Wonderscape GAS Ally plugin. It automatically initializes at game start, generates regeneration/degeneration effects from attribute definitions, caches them for efficient reuse, and provides the infrastructure for applying/removing periodic attribute changes where attributes automatically restore or drain over time (e.g., Health regeneration, Hunger degeneration).

Purpose

The Regeneration Subsystem orchestrates the automatic regeneration and degeneration system by providing:

• Automatic Effect Generation: Creates runtime Gameplay Effects at initialization from UWCGASAttributeDefinition regeneration/degeneration configurations
• Effect Caching: Stores generated effects for efficient reuse across multiple actors
• Per-ASC Tracking: Monitors which regeneration/degeneration effects are active on each Ability System Component
• Application Management: Provides functions to apply/remove regeneration and degeneration individually or in bulk
• Death State Handling: Automatically pauses regeneration when health reaches 0 and resumes on resurrection
• Delay Timer Management: Handles degeneration start delays when attributes are at maximum values
• Cooldown System: Applies cooldown effects when regeneration/degeneration is interrupted by blocking tags

How It Works

Initialization Flow

1. Subsystem Startup: When the GameInstance initializes, this subsystem automatically loads
2. Registry Dependency: Retrieves UWCGASAttributeRegistry subsystem to access attribute definitions
3. Scan Attributes: Loads all registered UWCGASAttributeDefinition assets using the registry
4. Process Regeneration: For each attribute with bEnableRegeneration = true:
   • Generates a regeneration Gameplay Effect (flat or percentage-based)
   • Generates a cooldown Gameplay Effect (if RegenerationStartDelay > 0)
   • Caches effects in CachedRegenerationEffects and CachedCooldownEffects maps
5. Process Degeneration: For each attribute with bEnableDegeneration = true:
   • Generates a degeneration Gameplay Effect (flat, percentage, or curve-driven)
   • Generates a cooldown Gameplay Effect (if DegenerationResumeDelay > 0)
   • Caches effects in CachedDegenerationEffects and CachedDegenerationCooldownEffects maps
