Completes the client-side combat loop: send attacks, receive server's
damage broadcasts, maintain per-entity health state for HP bars +
damage floaters. All atop Phase F.1's GameEvent dispatcher.
Wire layer:
- AttackTargetRequest (0x0008 C→S, inside 0xF7B1): targetGuid +
powerLevel + accuracyLevel + attackHeight. 28-byte body.
- GameEvents parsers for all combat notifications from r08 §4:
- VictimNotification (0x01AC) — you got hit, full details
- KillerNotification (0x01AD) — you killed X
- AttackerNotification (0x01B1) — you hit X for Y (damage%)
- DefenderNotification (0x01B2) — X hit you
- EvasionAttackerNotification (0x01B3) — X evaded
- EvasionDefenderNotification (0x01B4) — you evaded X
- AttackDone (0x01A7) — attack sequence completed
Core layer:
- CombatState: per-entity health-percent cache + typed events
(HealthChanged, DamageTaken, DamageDealtAccepted, EvadedIncoming,
MissedOutgoing, AttackDone). Each event carries enough detail for
the UI to render damage floaters, HP bars, and a combat log panel.
Server is authoritative; client only mirrors state.
The server computes damage (armor, resist, crit, hit-chance); the
client only displays results. Predictive UI like "estimated damage
at 0.75 power" still works via the existing CombatMath helper class
that was in the scaffold (r02 §5 formulas).
Tests (13 new):
- AttackTargetRequest byte-exact wire encoding
- VictimNotification / AttackerNotification / EvasionAttacker /
AttackDone round-trip parse.
- CombatState: UpdateHealth caches + fires, Victim fires DamageTaken,
Attacker fires DamageDealt, Evasion routes to right event, AttackDone
carries sequence+error, Clear resets cache.
Build green, 544 tests pass (up from 532).
