PlayerProfileComponent

PlayerProfileComponent implements ISaveable and automatically saves:
  • Player inventory
  • Equipment
  • Hotbar
  • Crafting state
  • Profile data

​
Player GUID

Each player has a persistent GUID: 
UPROPERTY(SaveGame)
FGuid PlayerGuid;

​
Auto-Registration

PlayerProfileComponent automatically registers with SaveSubsystem on BeginPlay: 
void UPlayerProfileComponent::BeginPlay()
{
    Super::BeginPlay();

    if (!PlayerGuid.IsValid())
    {
        PlayerGuid = FGuid::NewGuid();
    }

    USaveSubsystem* SaveSubsystem = GetWorld()->GetSubsystem<USaveSubsystem>();
    SaveSubsystem->RegisterSaveable(this);
}
