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"

There is not enough information here. So, im assuming your referencing an Ai character in your level blueprint? Did you tell your Ai Controller to run a behavior tree on its begin play? Did you give your Ai your own custom controller? Did you assign it to your Ai controller? And most likely your problem is that your doing this in the level blueprint which is almost never a good idea.
