액터 가져오기, Serialize

월드 내 모든 액터 가져오기

UWorld* CurrentWorld = GetWorld();
for (const auto& Entry : FActorRange(CurrentWorld))
{
  UE_LOG(LogTemp, Warning, TEXT("Actor : %s"), *Entry->GetName());
  TArray<UObject* > Components;
  Entry->GetDefaultSubobjects(Components);
  for (const auto& CEntry : Components)
  {
    UE_LOG(LogTemp, Warning, TEXT(" -- Component : %s"), *CEntry->GetName());
  }
}

원하는 타입의 액터만 선별하여 가져오기

for (TActorIterator<AStaticMeshActor> It(CurrentWorld); It; ++It)
{
  UE_LOG(LogTemp, Warning, TEXT("StaticMesh Actor : %s"), *It->GetName());
}

• 월드에서 StaticMesh만 뽑아낸 예시이다.

현재 월드에 로딩된 특정 언리얼 오브젝트를 가져오기

WebConnection->Host = TEXT("localhost");
WebConnectionNew->Host = TEXT("127.0.0.1");
for (TObjectIterator<UWebConnection> It; It; ++It)
{
  UWebConnection* Conn = *It;
  UE_LOG(LogTemp, Warning, TEXT("WebConnection Object Host : %s"), *Conn->Host);
}

• 액터를 포함해 현재 월드에 로딩된 모든 언리얼 오브젝트를 가져온다.

Serialize

WebConnection->Host = TEXT("127.0.0.7");
WebConnection->URI = TEXT("/");
if (UPackage::SavePackage(NewPackage, WebConnection, RF_Standalone, *FileName))
{
  UPackage* SavedPackage = ::LoadPackage(NULL, *FileName, LOAD_None);
  TArray<UObject*> ObjectsInPackage;
  GetObjectsWithOuter(SavedPackage, ObjectsInPackage, false);
  for (const auto& EachObject : ObjectsInPackage)
  {
    UWebConnection* WebConnectionFromFile = Cast<UWebConnection>(EachObject);
    if (WebConnectionFromFile)
    {
      UE_LOG(LogTemp, Warning, TEXT("WebConnection From File : Host %s , URI %s"),
        *WebConnectionFromFile->Host, *WebConnectionFromFile->URI);
