Class DiplomacyRelationManager

Namespace
Core.Diplomacy
Assembly
Core.dll

ENGINE LAYER - Manages opinion calculations and modifiers for diplomatic relations

RESPONSIBILITY:

  • Opinion queries (GetOpinion, GetBaseOpinion)
  • Opinion filtering (GetCountriesWithOpinionAbove/Below)
  • Opinion modifier management (Add/Remove)

PATTERN: Stateless manager (receives data references from DiplomacySystem)

  • Does NOT own NativeCollections (passed as parameters)
  • Pure methods for opinion calculations
  • Zero allocations in hot paths

PERFORMANCE:

  • GetOpinion: O(1) cache lookup + O(m) modifier scan (m = modifiers per relationship, ~10)
  • GetBaseOpinion: O(1) dictionary lookup
  • AddOpinionModifier: O(1) append to flat array
