I found the following code in World.h
AActor* SpawnActor( UClass* Class, FVector const* Location=NULL, FRotator const* Rotation=NULL, const FActorSpawnParameters& SpawnParameters = FActorSpawnParameters() );
But this is only the declaration and I am unable to find the implementation.
Also UWorld doesn’t seem to be inherited by any other class
Does anyone know where it is actually defined?
