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"

FBlackboardKeySelector Adding Enum Filter


I want to add a Enum to my filter for my FBlackboardKeySelector, but I'm not sure on how to add the enum. I have it available globally, but to assign in the AddEnumFilter parameter I'm not sure.

 EnemyKey.AddEnumFilter(this, /*HOW TO ADD ENUM*/);

Any help would be great :(

Hi. I do not experiment with this code. I only found it by search:

 UEnum* Enum = FindObjectChecked<UEnum>(ANY_PACKAGE, TEXT("EContentSourceCategory"));
 if (UEnum* Enum = Cast<UEnum>(InType.PinSubCategoryObject.Get()))
 UEnum* const DependencyRuleEnum = FindObject<UEnum>(ANY_PACKAGE, TEXT("EDependencyConversionRule"))

From Rama's code: https://wiki.unrealengine.com/Enums_For_Both_C%2B%2B_and_BP

 template <typename EnumType>
 static FORCEINLINE EnumType GetEnumValueFromString(const FString& EnumName, const FString& String)
     UEnum* Enum = FindObject<UEnum>(ANY_PACKAGE, *EnumName, true);
           return EnumType(0);
     return (EnumType)Enum->FindEnumIndex(FName(*String));
