ResistanceProcedure

Damage resistance step run by the defender after a successful attack. Built from a prepared payload (prep) produced by the attacking family (Firearm/Melee).

Role in the system​

  • Standalone follow-up test; not opposed and not a responder prompt.
  • Receives prep containing weapon identifiers, base TN, and resistance TN modifiers.
  • Computes final TN and runs a Body test by default.
  • Applies damage outcomes via OpposeRollService on resolution.

Responsibilities​

  • Seed state from prep:
    • targetNumberStore = prep.tnBase.
    • modifiersArrayStore = prep.tnMods (armor and situational effects).
    • dice = Body (from defender attributes).
  • Annotate SR3ERoll options with TN breakdown for rendering.
  • On resolve, call OpposeRollService.resolveDamageResistanceFromRoll with full context.

API reference​

  • Construction: ProcedureFactory.Create("resistance", { actor, args: { prep } }).
  • caller: overridden to always return the defender actor provided at construction.
  • getFlavor() / getChatDescription(): includes attack name and staged step information.
  • finalTN({ floor = 2 }): Computes clamp base + sum(modifiers), default floor 2.
  • async onChallengeWillRoll({ baseRoll, actor }): attaches TN base/mods/targetNumber into roll options.
  • async execute({ OnClose?, CommitEffects? }): Standard lifecycle; on resolve updates actor state.
  • exportForContest(): lightweight snapshot — familyKey/weapon references.
  • toJSON() / static fromJSON(obj): simplified serialization using only prep.
