## 关键依赖链

1. Item Creation: UItemRegistrySettings -> UItemRegistrySubsystem::Initialize -> ItemFactory::CreateItemInstance -> FItemInstance -> IItemContainer::InjectPayload -> UItemTracer
2. Item View: UDefaultContainer::GetItemViews -> FItemViewFactory::CreateView -> UItemRegistrySubsystem::GetViewStrategy -> IItemViewStrategy::GetPropertyText -> FItemView
3. Item Movement: IItemContainer::MoveItem -> InjectPayload (NVI) -> UItemTracer::SetItemLocation -> OnItemMoved delegate
4. Blueprint Inventory: IInventory::RequestMoveItem -> IInventory::ReceiveItem -> IItemContainer::InjectPayload
5. Item Lookup: UDefaultContainer::CreateItem -> UItemRegistrySubsystem::GetItemDef -> FItemDef -> ItemFactory::CreateItemInstance
