From 956a8f209ca3e758a2e2251735107bd97def5138 Mon Sep 17 00:00:00 2001 From: Denis Date: Mon, 24 Aug 2026 06:23:06 +0400 Subject: [PATCH 1/2] feat(vitality): maximum HP and MP stop being a login-time snapshot Max HP was computed once, in SelectPacketHandler, from class and level, and nothing ever recomputed it. Three things followed, none of which raise anything: * the Hp and Mp fields of the worn pieces counted for nothing - the parser has always read Item.Hp and nobody looked at it; * BCard type 33 "Maximum HP/MP", which sits on 706 items and is the second most widespread effect in the files, had no handler at all; * on level-up the full heal topped the player up to the *previous* level's maximum, and the new level's health only appeared after a relog. VitalityService answers "what is this character's maximum right now" and is called at the five points where the answer can change: login (after the inventory exists to look at), level-up (before the full heal, or the heal tops up to the old number), equip, unequip, and a buff arriving or expiring. BCard.dat, type 33, is what settles the order: 11: Maximum HP is increased by %s. 31: Increases maximum HP by %s%%. 21: Maximum MP is increased by %s. 41: Increases maximum MP by %s%%. 51: Maximum HP and MP are increased. For 31 and 41 the file adds "(Only used by buffs.)", so the percentages apply to the total that already includes the equipment, not to the base alone: a twenty percent buff is twenty percent of what is worn. Two things worth a reviewer's attention: * HitQueue.TryApplyHit is now async and awaits the buff application. It was fire-and-forget; the recomputation that follows has to see the effect already applied. The worker already serialised per target, so this orders work that was happening anyway. * Taking off a piece that gave HP lowers the maximum, so current HP is clamped under it - otherwise the client draws the bar past its own edge and the percentage in `su` passes a hundred. The tests equip a piece whose only contribution is HP, and a piece whose only contribution is a type 33 card, and read MaxHp back. Removing either contribution fails four of them. Depends on IEquipmentStatsService (#2293). --- .../Messaging/Handlers/UseItem/WearHandler.cs | 7 +- .../BattleService/BattleStatsProvider.cs | 4 +- .../Services/BattleService/HitQueue.cs | 32 ++- .../BattleService/IVitalityService.cs | 29 +++ .../Services/BattleService/VitalityService.cs | 177 ++++++++++++++++ .../ExperienceProgressionService.cs | 9 +- .../MapInstance.cs | 19 +- .../MapInstanceGenerationService.cs | 5 +- .../CharacterScreen/SelectPacketHandler.cs | 17 ++ .../Inventory/RemovePacketHandler.cs | 7 +- .../Handlers/UseItem/WearHandlerTests.cs | 3 +- .../BattleService/AdditionalVitalityTests.cs | 61 ++++++ .../Services/BattleService/HitQueueTests.cs | 9 +- .../BattleService/VitalityServiceTests.cs | 197 ++++++++++++++++++ .../SelectPacketHandlerTests.cs | 1 + .../Inventory/RemovePacketHandlerTests.cs | 3 +- test/NosCore.Tests.Shared/TestHelpers.cs | 5 +- 17 files changed, 564 insertions(+), 21 deletions(-) create mode 100644 src/NosCore.GameObject/Services/BattleService/IVitalityService.cs create mode 100644 src/NosCore.GameObject/Services/BattleService/VitalityService.cs create mode 100644 test/NosCore.GameObject.Tests/Services/BattleService/AdditionalVitalityTests.cs create mode 100644 test/NosCore.GameObject.Tests/Services/BattleService/VitalityServiceTests.cs diff --git a/src/NosCore.GameObject/Messaging/Handlers/UseItem/WearHandler.cs b/src/NosCore.GameObject/Messaging/Handlers/UseItem/WearHandler.cs index 4400c31e7..038fa2268 100644 --- a/src/NosCore.GameObject/Messaging/Handlers/UseItem/WearHandler.cs +++ b/src/NosCore.GameObject/Messaging/Handlers/UseItem/WearHandler.cs @@ -32,7 +32,8 @@ public sealed class WearHandler( ILogger logger, IClock clock, ILogLanguageLocalizer logLanguage, - IOptions worldConfiguration) + IOptions worldConfiguration, + Services.BattleService.IVitalityService vitalityService) { [UsedImplicitly] public async Task Handle(ItemUsedEvent evt) @@ -192,6 +193,10 @@ await session.Character.MapInstance.SendPacketAsync( itemInstance.ItemInstance.ItemDeleteTime = clock.GetCurrentInstant().Plus(Duration.FromSeconds(itemInstance.ItemInstance.Item.ItemValidTime)); } + + // A piece can carry HP and MP as its own value or as a type 33 effect.
