Espelho simétrico do front-end pattern (UUIFrontEndFlowSubsystem +
DA_FrontEndScreenSet + UUIPrimaryGameLayout_Base) para a UI in-game.
Pavimenta caminho pra Inventory, Skills, StatusWindow, EscapeMenu, etc.
## UI in-game system (Source/ZMMO/Game/UI/InGame/)
- EZMMOInGameUIState enum (None, Playing, StatusWindow, Inventory,
SkillTree, EscapeMenu, Loading) em Data/UI/InGameTypes.h
- UUIInGameScreenSet DataAsset: TMap<EZMMOInGameUIState, TSoftClassPtr<...>>
- UUIInGameFlowSubsystem (GameInstanceSubsystem) com SetState/ToggleScreen
- DA_InGameScreenSet em Content/ZMMO/UI/InGame/ mapeia Playing->WBP_HUD
- Layer routing: Playing -> UI.Layer.Game | menus -> GameMenu | loading -> Modal
## AHUD pattern (idiomatic UE5)
- AZMMOHUD : AHUD em Source/ZMMO/Game/Modes/
- AZMMOGameMode::HUDClass = AZMMOHUD::StaticClass()
- AZMMOHUD::BeginPlay chama UIInGameFlowSubsystem::StartInGame
- Pawn não cria mais HUD (separação de responsabilidades)
## PlayerState + Component Registry (Open-Closed)
- AZMMOPlayerState : APlayerState em Source/ZMMO/Game/Modes/
- AZMMOGameMode::PlayerStateClass = AZMMOPlayerState::StaticClass()
- UPROPERTY Config TArray<TSubclassOf<UActorComponent>> ComponentClasses
- DefaultGame.ini: +ComponentClasses=/Script/ZMMOAttributes.ZMMOAttributeComponent
- Ctor lê via GConfig (mais robusto que UPROPERTY Config + parsing) e
instancia cada componente como CreateDefaultSubobject
Por que componentes no PlayerState e não no Pawn:
- Sobrevive ao despawn (morte/respawn)
- Spectator-friendly
- 1:1 com player (Pawn pode trocar: vehicle, mount, possession)
- Padrão MMO clássico (rathena, TrinityCore)
Adicionar novo módulo (Inventory, Skills, Guild) = 1 linha no
DefaultGame.ini, sem editar AZMMOPlayerState.cpp.
## HUD composite
- UZMMOHudWidget : UCommonActivatableWidget em ZMMO core (UI/InGame/)
- WBP_HUD em Content/ZMMO/UI/HUD/ herda UZMMOHudWidget
- HpSpBar (UZMMOHudHpSpWidget — sub-modulo ZMMOAttributes) embedded via
BindWidgetOptional. Sub-widgets futuros: PlayerInfo, Minimap, QuickBar,
Buffs, Chat, TargetInfo
- UZMMOHudHpSpWidget volta a ser UUserWidget puro (sub-widget, não root)
- UZMMOHudWidget::NativeOnActivated:
- SetVisibility(HitTestInvisible) — mouse passa direto pro Pawn
- BindToLocalPlayer: busca AttributeComponent no PC->PlayerState
- Subscreve OnAttributesChanged/OnHpSpChanged/OnLevelUp
- Propaga snapshots pra sub-widgets via HpSpBar->ApplySnapshot
- GetDesiredInputConfig override: ECommonInputMode::Game (sem cursor,
movimento livre). Menus override pra GameAndMenu/Menu.
## NetworkHandler refatorado (AttributeComponent agora no PlayerState)
- ZMMOAttributeNetworkHandler::FindComponentForEntity: busca via
GameState->PlayerArray (O(N_players)), não TActorIterator (O(N_actors))
- ZMMOAttributes.Build.cs += CommonUI, CommonInput
## EnsureRootLayout (fix crítico)
- OpenLevel invalida widgets no viewport ("InvalidateAllWidgets")
- RootLayout (criado pelo FrontEndFlow no boot) sobrevive como UObject
(LocalPlayerSubsystem) mas fica órfão fora do viewport
- Push do WBP_HUD no Stack_Game funcionava mas widget pai (RootLayout)
estava fora do viewport → invisível
- UUIFrontEndFlowSubsystem::EnsureRootLayout (público) recria via
UIManagerSubsystem (idempotente)
- UUIInGameFlowSubsystem::StartInGame chama EnsureRootLayout antes do push
## PlayerCharacter simplificado
- Removido AttributeComponent (vai pro PlayerState via Registry)
- Removido HudHpSpWidgetClass + spawn manual de HUD
- HandleLocalSpawnReady só faz seed do EntityId via PlayerState
- UI lifecycle agora é responsabilidade do AZMMOHUD::BeginPlay
## Verificação (smoke test)
PIE: Login -> CharSelect -> Lobby -> EnterWorld
↓
LogZMMO: AZMMOPlayerState ctor: 1 componente(s) no registry
LogZMMO: ZMMOPlayerState: componente registrado [0] ZMMOAttributeComponent
LogZMMO: FrontEndFlow::EnsureRootLayout: RootLayout recriado
LogZMMO: InGameFlow: state None -> Playing
LogZMMO: InGameFlow: tela Playing pushed em UI.Layer.Game (widget=WBP_HUD_C_0)
LogZMMO: ZMMOHudWidget activated (HpSpBar=WBP_HUD_HpSpBar_C_0)
↓
HUD aparece com Lv 5 / HP 10/200 / SP 5/20 (valores do DB)
Regen funciona (HP/SP enchem a cada 6s/8s)
Movimento normal (input flui pro Pawn)
