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"

I would think you want something like this: https://docs.unrealengine.com/latest/INT/Engine/AI/EnvironmentQuerySystem/QuickStart/index.html

EQS is a very powerful tool and it's the typical way this type of thing would be done.

Randomization can be done many ways. The easiest would be to use EQS to find all the reachable points within a radius and then put them into an array and use a random int in the range of 0 to Array.Length - 1 to get a random point from the array. There are other ways to do it but that's the first thing that comes to mind.

Converted comment to answer, I'm pretty sure that's what you need. We did something similar (similar concept at least) and EQS worked very well for us
