🌍 WORLD CONTEXT DATA REGISTRATION

WorldContextData

TArray<TSoftObjectPtr<UWCGASWorldContextData>>

What it is: Array of World Context Data Assets that define environmental contexts and their elemental modifiers. Each asset represents one context (Rain, Forest, Night, etc.) and specifies how that context affects abilities and effects based on their element tags.

Systems that access it:

• WCGASWorldContextSubsystem - Loads all assets at world startup and builds a ContextDataRegistry TMap for O(1) context lookups by tag
• WCGASExecCalc_BaseDamage - Queries the subsystem for Magnitude modifiers during damage calculations
• AWCGASContextVolume - References context tags defined in these assets when configuring zone-based contexts
• Editor Validation - Validates ContextTag uniqueness across all assets and warns about empty ElementRules arrays

Why it matters: This is the master definition for all environmental contexts in your game. Contexts registered here can be activated globally, per-zone, or per-actor to modify how elemental abilities and effects behave. Without context definitions, the World Context System has nothing to apply—abilities function normally but environmental factors have no impact.

If left empty: World Context Subsystem initializes with an empty registry. All GameplayEffects function normally via GAS, but GetContextModifier() always returns 0.0, zone volumes have no effect definitions to apply, and environmental gameplay is disabled. The console logs a warning directing you to add assets in Project Settings.

🏷️ ELEMENT IDENTIFICATION

ElementTagPrefix

FGameplayTag - Default: Effect.Element

What it is: Tag prefix used to identify element tags on GameplayEffects. ExecCalcs search GE AssetTags for child tags of this prefix to determine which element's context modifiers should apply to the effect.

Systems that access it:

• WCGASExecCalc_BaseDamage - Searches GameplayEffect AssetTags for tags matching this prefix to identify the effect's element
• World Context Subsystem - Uses this prefix when validating element tags in context data assets
• Designer Validation - Warns if GameplayEffects lack element tags when context modifiers would otherwise apply
