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"

Run custom event in given actor

I'm tracing the position of the mouse to get the object under the cursor position, I also have different actors in the world where some have a certain tag. Now I'd like to run a custom event if the trace hits an object with the given tag. The event is called the same in every actor with that tag and every actor with that tag has that custom event.

So, I'd like to know if there is a quick way to just run that event without getting which object it is (which Blueprint), then casting and all that? Just something like if it has that tag, run the custom event with that name.

From the Hit Result you can check if the Actor has the tag or no by using ActorHasTag node.

Even though you can use this method, my personal suggestion is to use Interface. It would be the best choice in this situation.

thx for the information, I've already got the tag, but had to check what type it is, then cast to it and then run the event, but interface sounds really intersting I'll check it out

Edit: Was exactly what I needed, thx for the help
