Struct ScopedModifierContainer

Namespace

Core.Modifiers

Assembly

Core.dll

ENGINE: Container for modifiers with scope inheritance Pattern used by: EU4 (province ← country ← global), CK3 (character ← dynasty ← culture)

Scope Hierarchy:

• Province modifiers (local only)
• Country modifiers (inherited by all provinces)
• Global modifiers (inherited by everyone)

Design:

• ActiveModifierList for local modifiers
• Reference to parent scope (optional)
• Cached ModifierSet (dirty flag optimization)
• Rebuild only when modifiers change

Performance: O(n) rebuild where n = local + inherited modifiers Cached lookups: O(1) after rebuild
