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"

TArray initialisation for default values of function

In my header file of a game controller class, i have multiple structures: FElementData, FElementReference, and FMolecule. In my FMolecule struct, i am aiming to have a list of FElementReferences as one of the properties. So far my code looks like:

 USTRUCT(BlueprintType, Category = "GMT Library|Custom Data Types|Structs|Components")
 struct FMolecule
         UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Element Data")
         TArray<FElementReference> elements;
     FElementReference(TArray<FElementReference> newElements)

Now, I am trying to set a default value for the newElements array, something like:

 FElementReference(TArray<FElementReference> newElements = {})

However, that does not work with TArray. I'm getting a variety of errors depending on what I put and I'm just really confused. I have the FElementReference struct before this one, and the FElement before that, if that helps. Also, my class declaration is after all structs.
