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"

Switch behavior trees while active

I have my AI run one behavior tree by default and that behavior tree contains everything to act as a normal citizen. This behavior tree also checks to see at any time to see if the NPC has changed to a "Guard" or a "Infected State" and for each I want separate tree for Citizen/Guard/Infected State, each with their own individual blackboard. I try and run one of them from one behavior tree and if they have any blackboard set other than the one that the default tree has they wont execute.

I found a way around this. If there is a better way to do this please let me know. What I did was created a new task that stopped the current tree and then executed a different tree.

Thank you, this worked a lot better and more efficient compared to my last way of doing it.
