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"

1) What type of BP is "My Swords"?

2) How do you cast, how do you select BP you need?

Well, first - you can't just cast it and give the cast value to different exec - you have to connect "Cast to BP_CharacterAI" into main stream(Or into the main stream, or the exec pin of BP_CharacterAI to exec of SwordBack2.

Also i can't understand double check in "Cast to BP_FirstPersonCharacter", and then Hit Component check. Also first branch don't have any purpose, but whatsoever. Try to do this first, because that what i can see right now. (also please give full code of line trace)
