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"

How to allow Cycles and multiple Parents in custom AI-Nodes

Hello,

I have created custom nodes that can be used in a behavioural tree; they inherit from UBTComposite_Selector. Coventional nodes do not allow two parent nodes, and they do not allow cycles, meaning a child connects back to a parent. For my own reasons, I must allow this though. The purpose of my custom nodes has nothing to do with AI - I am enabling level designers to implement my features by drawing a tree.

I though there might be some properties that I should set, or some function to override that will handle this for me. Any suggestions?

I know there is a property 'ParentNode' in BTNode indicating that one parent is intended but maybe it is possible in some hacky way? As I said, the AI features do no need to work, I just need to be able to read from the 'Children' property. As well, how do I add links in between nodes in the graph from code? How would does links be read when I analyse the tree?
