Module: Lich::Gemstone::Combat::Definitions::Attacks

Defined in:

documented/gemstone/combat/defs/attacks.rb

Overview

Combat attack patterns and definitions for matching in-game combat messages.

Defines structured patterns that match player and companion attacks from game output, organized into categories: basic weapon attacks, spells, weapon maneuvers, and companion actions. Uses a literal-substring gate for fast rejection of non-matching lines (~7us/line) before attempting regex matching.

Weapon maneuvers

[
  AttackDef.new(:cripple, [/You reverse your grip on your .+? and dart toward (?<target>.+?) at an angle!/].freeze),
  AttackDef.new(:flurry, [
    /Flowing with deadly grace, you smoothly reverse the direction of your blades and slash again!/,

    /You turn, blade spinning in your hand toward (?<target>[^!]+)!/,
    /You angle your blade at (?<target>.+?) in a crosswise slash!/,

MANEUVER_ATTACKS =

Combat maneuvers

[
  # AttackDef.new(:hamstring, [/You(?: make a precise)? attempt to grapple (?<target>[^!]+)!/].freeze),
].freeze

SHIELD_ATTACKS =

Shield-based attack patterns (currently unused; reserved for future implementation).

Returns:

• (Array) —

  empty frozen array

[].freeze

COMPANION_ATTACKS =

Companion/pet attacks

[
  AttackDef.new(:companion, [
    /(?<companion>.+?) pounces on (?<target>[^,]+), knocking the .+? painfully to the ground!/,
    /The (?<companion>.+?) takes the opportunity to slash .+? claws at the (?<target>.+?) \w+!/,
    /(?<companion>.+?) charges forward and slashes .+? claws at (?<target>.+?) faster than .+? can react!/
  ].freeze)
].freeze

ENVIRONMENTAL_ATTACKS =

Environmental attacks

[].freeze

ALL_ATTACKS =

All attack definitions combined

(BASIC_ATTACKS + SPELL_ATTACKS + MANEUVER_ATTACKS + WEAPON_ATTACKS +
SHIELD_ATTACKS + COMPANION_ATTACKS + ENVIRONMENTAL_ATTACKS).freeze

ATTACK_LOOKUP =

Create lookup table for fast pattern matching

ALL_ATTACKS.flat_map do |attack_def|
  attack_def.patterns.compact.map { |pattern| [pattern, attack_def.name] }
end.freeze

ATTACK_DETECTOR =

Compiled regex for fast detection. NOTE: costs ~0.5ms per non-matching line (unanchored .+? alternatives); kept for compatibility but the literal gate below is what the parser uses.

Regexp.union(ATTACK_LOOKUP.map(&:first)).freeze
