Game Mechanics

Overview​

The game mechanics system encompasses Skills, Items, Conditions, Effects, and Abilities (stats) that form the LARP rule engine. Effects are the fundamental building blocks that modify ability scores.

Features​

Abilities (Stats)​

  • Numeric stats that characters are scored on (XP, mana, HP, etc.)
  • Base value defaults to 0
  • Used by CharacterService.initializeAbilityScores() for starting values

Effects​

  • Modify ability scores via positive or negative modifiers
  • Target one or more abilities via abilities[] array or stat_id
  • Bridge between game elements (skills, items, conditions, events) and character stats

Skills​

  • Carry effects that modify character abilities
  • Support prerequisite system (other skills, stats, conditions)

Items​

  • Equipment and objects that carry effects
  • CRUD via generic object store

Conditions​

  • Status effects (poisoned, blessed, etc.) that carry effects
  • Applied to characters during stat calculation
  • Abilities, Skills, Effects: Settings footer area
