What do you need to know for libGDX?

Question

Java

Hello everyone, I decided to learn java and libGDX, I know that you will have to learn the basics of java, but for example, I don’t know OOP, to teach or not to teach, or something else like that? I know what kind of graphics in libgdx is opengl , should I learn it or not? In short, what do you need to know to work with libGDX?
PS And what else do you need to know from mathematics (for example, vectors, etc.)

Answer 1

OOP is a must. opengl is highly desirable. java - I'm afraid you won't get off with just the basics. Well, judging by the question, the idea of ​​​​computer graphics is minimal, so it would also be nice to get acquainted with it
