what types of query to collide with


I'm Spanish and I just started to learn Unreal Engine (a game engine).

In the following paragraph I don't understand the meaning of query:

Trace Channels and Object Channels
The next big question at the heart of collision filtering is “who gets to choose?” Is it the object that decides what types of query to collide with? Or does the query decide what types of object it is looking for? In different scenarios they both make sense, so UE4 supports both!

What does query mean in that context?

You can find the article here.

Change of the thread's title. Please, avoid words that are not part of the word/phrase you are asking about. Thanks. Ayutuxtepeque (Moderator).

  • "query" is translated as "pregunta/preguntar" or "consulta/consultar"
    I'm not familiar with this context, but after reading the article page your pointed to, it looks like questions are asked, and answers are obtained such as "block/ignore/overlap".

    This definition of query might help:
    "In standard English, a query means a request for information. In computer programming, it refers to the same thing, except the information is retrieved from a database.
    However, writing a query requires a set of pre-defined code to make the database understand the instruction. This concept is also known as the query language.
    While the standard language for database management is Structured Query Language (SQL), other query languages to make database communication easy include AQL, Datalog, and DMX." What Is a Query? Database Query Explained
