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"

AI Perception History

I have managed to get basic AI perception working fine. however, when running the ai debug I noticed that a perceived actor's last known location was stored along with the age of the stimulus. I couldn't find where the actor's last known location and age is stored, as the documentation is still not the best on AI Perception. Does anyone know where this is stored on the component?

Actually, reading engine's code is way better and faster than using the documentation. :)

UAIPerceptionComponent contains PerceptualData private property. It's a map AActor -> FActorPerceptionInfo. The values within this map, have GetLastStimulusLocation function that reads this information from internal array of elements of type FAIStimulus.

Hope this helps.

Thanks, this is what I ended up using. I forgot to post that I had figured it out from the engine code like you mentioned.
