虚幻4 C++寻找实例

1.寻找所有的UObject实例

int i = 0;
for (TObjectIterator<UObject> uuobject; uuobject; ++uuobject)
	{
		UObject* currentObject = *uuobject;
		GEngine->AddOnScreenDebugMessage(i, 100.f, FColor::Green, FString(*currentObject->GetName()));
		i++;
	}

2.寻找世界所有的Actor实例（地图上的物体）

int i = 0;
for (TObjectIterator<AActor> actor; actor; ++actor)
    {
        UObject* currentObject = *It;
        GEngine->AddOnScreenDebugMessage(i, 100.f, FColor::Green, FString(*currentObject->GetName()));
        i++;
    }

3.寻找地图上所有的某类的实例

int i = 0;
for (TActorIterator<AMyCharacter> character(GetWorld()); character; ++character)
	{
		AMyCharacter* item = *character;
		GEngine->AddOnScreenDebugMessage(i, 100.f, FColor::Green, FString(*item->GetName()));
		i++;
	}

4.注意：AActor派生自UObject，因此也可以使用IObjectIteractor找到AActor实例。
