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"

You do that by standard collision system, since rendering is pretty much done from same data (not to mention UE4 in dedicated server mode is force to do things without rendering with only collision system), and you do it same as you would check object colliding, in this case with view distance or line of sight. Ue4 even provides trace category "Visibility". You can do shape trace which checks if object is inside of shape or by line trace by checking if object collides with line. here docs:
