The easiest C++ game engine to learn?

Question

C++ / C#

I've been learning C++ for six months now. Now I have already studied the basics of OOP, pointers. In the future I would like to develop games (most likely on PC). It is interesting to start learning development on the engine. Which one is recommended for beginner developers / easiest to understand and use? (preferably free)
I read that the Cocos 2d creator engine is a good option. As far as I understand, 2D is easier to work with than 3D. I will be very grateful for the answers.

Answer 1

I recommend watching Godot — now I would call it the most interesting, thoughtful and understandable of the small engines.

Answer 2

Just don't confuse easy and quick to use with easy and quick to understand.
Its self-written engine is the easiest to learn because there is less code and concepts involved.
In fact, there is little difference between 2d and 3d at the moment, unless you are going to make a pilgrimage and write your own software render, 2d is easier only in terms of level design.
Cocos 2d creator is not an engine, but a complete workflow toolkit for disassembling a game, with a focus on assets. Documentation for Cocos2-x is what you should be interested in first.
In general, you can take any engine that has thick documentation and many examples.

Answer 3

The documentation is the most complete at Unreal Engine, but mostly Blueprints are used there, not pluses.
