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"

How to check how long an actor has been spawned

Hello,

I'm trying to create to type of actors that overwrite each other (dots on the ground at the moment). But I want them to destroy the other only if the other is older ( so that both don't get destroyed every time they overlap)

Thank you !

I think the simplest way to do this is just to add a FDateTime variable (call it "Lifetime" or some such) to your actor. When your actor is constructed you can just set that variable to FDateTime::Now(), then just compare the two actors lifetimes when a collision happens and run whatever logic you want.

Thank you, that would certainly work. One thing I can't seem to succeed to do is compare the actor variable to one of the actor not yet created. I can't cast it from the overlap node, since it's a generic node. Not sure if I'm clear here, all in all I'm just not sure how to compare the two on the overlap occurred.
