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 actors are stored in Engine?

HI Guys, I was wondering how are Objects (Actors, UObjects) stored in the Engine. I think that there should be some massive TArray or Set which is iterated every frame to call Update and Render function on every object.

Does someone know how it work?

Thanks for any answer.

Hey there, i don't know the specifics but my guess is that on every level instance there is an array of actors that belong to it.

I am trying to implement component system to my engine for game. And i dont know how to manage storaing of actors.

So you are creating your own engine for your game and want to see what ue 4 does as a reference? The engine is a bit more complex to just have a simple Update or Render functions for them. For the Update you have to look at the code and see what PrimaryTickActor does, because afaik that is what calls the tick function. Can't help you with the Render function, not familiar with the engine code on that part.
