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"

Behavior tree suddenly stops working

I do not know when this problem began, but it has become a major barrier to progress. The AI is happily running through its tasks when suddenly all items inside the tree fail and all blackboard variables become false. I do not think the services are running either. This happens at random times. enclosed are the pictures of my code. AI_BP

1 answer: sort voted first

Well, I think I have fixed the problem. When two specific tasks (Stalk and Chase) were false at the same time, the AI could not move on to any other tasks because they are false and outside of the specific selector.
