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"

It's an array composed of Actors. I have this class "Participant", it's an actor and when I create this, i got errors:

      UPROPERTY(BluprintReadOnly, EditAnywhere, Category = "Points")

               TArray<AParticipant> participants;

If you include AParticipant in cpp, then in .h file before your class add class AParticipant:

 class AParticipant;
 
 class PRO_API AMyActor : public AActor
 {
     GENERATED_BODY()
 
 private:
     TArray<AParticipant*> participants;
 }

Or just:

 TArray<class AParticipant*> participants;

Still says that AParticipant identifier is not defined.

Well you have to #include the .h file of course.
