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"

Why use Blackboard instead of object

I have read this question about why not to use variables on the pawn directly instead of the blackboard. The answer given makes sense - decouples the AI from the pawn it is controlling.

My question is why use a blackboard and not a UObject-derived blueprint. This way you would have compile time checks on the variable names (i.e. wouldn't have to use the error prone and tedious process of entering the keys). It also doesn't seem to be any more tightly coupled, since to change blackboard would require the new one to have the same keys to not cause issues.

I also can't see how there can be under-the-hood technical issues as you can store an object in the blackboard. So what is the design justification for the blackboard being implemented separately from a standard UObject?
