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"

Multi layer dynamic behaviour trees don't work?

So, I got single-layer dynamic behaviour trees working.

What I have right now is - A base behaviour tree A dynamic behaviour tree for doing attacks with two types, one for projectile attacks, one for chasing.

I set the above up with these nodes: alt text

The above works.

Now I want to add a behaviour tree for my AI to do their specific kind of projectile attack, so I add the following nodes

alt text

However, this tree never gets called within my 'Project Attack' behaviour tree. I'm guessing this is because the behaviour tree I'm attaching it to is still my 'base' tree that I get from the brain component. However, I don't see a way to access the dynamic behaviour tree I've just attached. Is there some way for me to get this to work?

Anything here? This seems like something people would want when setting up more complicated setups of AI.

Preliminary tests seem like this may be fixed now.
