Espelho do AttributeSystem do servidor (Game/MMO/Modules/AttributeSystem).
Sub-modulo C++ Source/ZMMOAttributes/ (Runtime, LoadingPhase=PreDefault)
isolando o cliente do AttributeSystem em pasta propria — pavimentando o
caminho para futuros Inventory/Skills/Combat virem como sub-modulos peer.
Componentes:
- FZMMOAttributesSnapshot (USTRUCT Blueprint, espelha
FZeusAttributesPayload do plugin ZeusNetwork)
- UZMMOAttributeComponent (UActorComponent ligado ao player):
ApplySnapshot / ApplyHpSpUpdate / NotifyLevelUp + 3 delegates
dinamicos (OnAttributesChanged / OnHpSpChanged / OnLevelUp) +
helpers GetHpRatio / GetSpRatio
- UZMMOAttributeNetworkHandler (UWorldSubsystem): ponte
UZeusNetworkSubsystem -> componente via lookup por EntityId
- UZMMOHudHpSpWidget (UUserWidget base): BindWidget (HpBar, SpBar) +
BindWidgetOptional (HpText, SpText, LevelText). NativeConstruct
binda nos delegates do componente; NativeDestruct desliga.
OnSnapshotApplied / OnHpSpDelta (BlueprintNativeEvent) com impl
C++ atualizando progress bars e textos.
Integracao no PlayerCharacter:
- CreateDefaultSubobject<UZMMOAttributeComponent> no ctor
- HudHpSpWidgetClass (TSubclassOf) resolvido via
ConstructorHelpers::FClassFinder em /Game/ZMMO/UI/HUD/WBP_HUD_HpSpBar
- HandleLocalSpawnReady seed do EntityId no componente + spawn do HUD
(CreateWidget + AddToViewport + BindToAttributeComponent)
- EndPlay remove widget do parent
WBP_HUD_HpSpBar (UMG, criado via MCP):
- Overlay root + SizeBox (320x120) + VerticalBox
- 5 widgets BindWidget: LevelText, HpBar (vermelho), HpText,
SpBar (azul), SpText
- Herda de UZMMOHudHpSpWidget
Verificacao (smoke test):
- PIE login -> server envia S_ATTRIBUTE_SNAPSHOT_FULL
- Cliente recebe via OnAttributeSnapshotFull -> handler roteia pra
componente do entity -> ApplySnapshot dispara OnAttributesChanged ->
widget atualiza ProgressBars + TextBlocks
- HUD aparece no canto inferior esquerdo da tela com valores
correspondentes ao DB
