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"

Most efficient way to turn on and off many stationary lights at once

The title says it all. I have a level with about 150 stationary lights that I must turn on and off all at the same time. I see some simple ways of doing this but I'd like to know what's correct way of doing something like this from a performance-wise viewpoint, I don't want to have an fps drop because of this or at least limit the "damage".

Thanks in advance.

PS: I put this question into the "Blueprint scripting" category but if needed I can use C++, my project gets nativized anyways.

You can make a custom loop with delay like this:

Set Delay duration to lowest you can get without a hiccup.
