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"

BeginOverlap called twice for one overlap

I have a simple setup of one blueprint with a box component with an OnComponentBeginOverlap event. When an actor enters the box, it is added to an array. The problem is that sometimes BeginOverlap gets called twice because EndOverlap gets called. This doesn't happen every time and seems to be completely random when it does. EndOverlap shouldn't be getting called because the actor never leaves the box once it enters. In fact, it just stops about half way into the box every time.

1 answer: sort voted first

Well, I figured out it has something to do with the movement of the actors as they hit the box. I was interpolating their location and rotation, but if I just teleport them to the box, BeginOverlap only gets called once. It could be they were rotating in and out of the box faster than I could see it.
