Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Casting actor to interface returns null; calling ImplementsInterface returns true

When I run this code here:

 AActor* actor = hitResult.GetActor();
 IUnit* IUnitActor = Cast<IUnit>(actor);
 bool bIsIUnit = actor->GetClass()->ImplementsInterface(UUnit::StaticClass());  

IUnitActor is null, while bIsIUnit is true. The actor doesn't implements the interface in C++ code, but in his blueprint editor. Why does the cast returns null and how can I call functions from the interface on the actor? Or do I need to create a C++ class that directly implements the Interface?
