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"

Event OnBecomeViewTarget questions

I'm curious how this event works and what it's intended uses are? May assumption was that this would fire whenever an object was "looked at" by a camera but that appears to not do anything.

Is there some documentation for this event?

What is the "best" way to fire events on blueprints I am looking at? I have seen this done with line traces and vector math and such but I was wondering if these were inefficient since I would need to do a lot of tracing to make these items responsive enough.

Product Version: UE 4.10

OnBecomeViewTarget does't work this way. This event fires when PlayerController starts to use CameraComponent of this Actor (to "see through" this camera).

Why not to use line trace? If it is about performance, then just not do the line trace each frame.
