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"

[Closed] Search for actors visible on the screen?


Is there a way to only search for actors visible on the screen? Or e.g. how do you run a collision test with a shape like the view frustum in code?

You may want to check out Rama’s work which is linked below already. It’s written in C++ and can also be used in blueprints. If that doesn’t meet your needs for any reason you can implement your own custom solution that suits your game. That can be done by e.g. doing some basic build in collision checks or otherwise I’m afraid that you will have to use some math/black magic.

Do you want to do it in C++ or Blueprints?

Rama recently released some blueprint functions. One of them gets currently rendered actors. Link

I know its a bit late, but were you able to get Rama's blueprint functions for actor visibility to work? Thanks!

It worked but I ended up just using some collision checks and then iterating through the actors.
