Game Engine Development with C++ and OpenGL (Udemy.com)

In dem Kurs wird die grundlegende Struktur einer Game Engine dargelegt. Die Gedankengänge des Dozenten lassen sich sehr gut verfolgen. Zu dem stellt er umfangreiches Studienmaterial (Source Code und Transkripts der Lessons) bereit. Somit hat jeder Teilnahme die erstellte Game Engine zur weiteren Bearbeitung zur Verfügung. Der Aufbau des Kurses ist sehr gut, an der einen oder anderen Stelle wäre vielleicht noch eine Erklärung hilfreich gewesen, die sich dann aber aus der Analyse des Source-Codes ergibt. Voraussetzung für den Kurs sind C++17-Kenntnisse.

Just completed Game Engine Development with C++ and OpenGL. This wasn’t just another course for me. It pushed me out of my comfort zone in a few ways. The course was taught using Windows and Visual Studio, but I followed along on macOS using VS Code. That meant figuring out build issues, dependencies, and OpenGL setup on my own alongside the actual learning. At times, it slowed me down, but in hindsight, that’s where a lot of the real learning took place. I got hands-on experience building core engine systems like rendering, UI, input handling, and component-based design. More importantly, I learned how these pieces connect rather than just writing isolated code. There were definitely frustrating moments. Things were breaking for reasons that weren’t obvious, platform differences, and debugging issues that had nothing to do with the lecture itself. But those moments forced me to think deeper and not just follow along passively. Big thanks to Alex Kulbitsky for structuring the course in a way that makes you build things from scratch and actually understand what’s going on under the hood. This journey gave me a much clearer picture of how game engines work internally and where I need to improve next.

The course is great for learning about how to actually get a functional project, rather than the hyper specialisation of other courses on just the OpenGL/Rendering engine part of game engines. The only thing that brings it down for me is the lack of proper error handling, the tutor likes to use a lot of "nullptr", not a huge issue for learning, but could catch you out in some sneaky ways. I chose to wrap many of these in std::optional & std::expected

This course is extremely disappointing. It feels like the content was generated by ChatGPT, with nothing natural or well-explained in the delivery. The instructor mostly types and reads code without real explanations, making it very hard to follow. The code architecture is very poor, with bad practices and some functions being several hundreds of lines long, along with constant compilation errors and warnings. The tools feel outdated, it does not work on macOS or Linux, and you are forced to download many ZIP folders for almost every lecture, which feels slow and unsafe. Overall, this course can easily discourage young programmers from learning game engine development.

This is one of the best courses I've ever done on udemy! I went through 3 hours of it in one go and that has never happened to me before. I did however have to watch the course at 1.5X the speed. Not because the instructor is boring, but because of the coding pace. As a bit of constructive feedback, I would recommend having the code pre-written, deleted and then just press ctrl+z to kind "rewrite" it on screen. That way the instructor could comment on it as it appears on screen without having to spend lots of time typing it. Also, the course could also do with a bit more diagrams and explanation around certain things, but I understand this is not a maths course or a c++ course. Nevertheless, brilliant course! I am loving it so far!

This course feels like a clean X-ray of any modern 3D game engine — Unreal, Unity, Godot, you name it. The concepts are universal, and here they’re broken down just deep enough for you to finally see that there’s no magic behind the curtain. The instructor shows step by step how engines hide low-level libraries and graphics APIs behind higher-level abstractions, and you actually get to understand how the tools we use every day are built. The material is structured beautifully: complexity increases only when it truly makes sense, and the small theory breaks give you enough understanding to stay engaged instead of overwhelmed. The real-engine examples are a huge bonus — this isn’t theory for the sake of theory, but practical, grounded insight into how things work in real production environments. The code is clean and easy to follow, and the setup never tries to limit your workflow. Could there be more modern C++ features in action? Sure. But the course isn’t about C++ itself — and in its main mission, it delivers perfectly. A big highlight is how many subsystems the course covers: rendering, windowing, physics, animation, UI, asset management. Usually graphics and physics are separated into different worlds, but here they’re taught together, just like in an actual engine. Because of that, the course works both for beginners and for experienced developers who want to fill in gaps or refresh their knowledge. And honestly, the instructor’s voice and pacing deserve their own compliment — the course is incredibly pleasant to listen to, almost like a tech ASMR session. Calm, clear, steady… the kind of lectures you can put on and naturally slip into the flow of learning without stress. All in all, this is a fantastic starting point for anyone who wants to understand how game engines really work, how 3D graphics behaves at a low level, and how to assemble your own engine from scratch. Practical, accessible, thorough, and surprisingly soothing to listen to. Highly recommended!

Русский: Этот курс очень хорош, и преподаватель объясняет всё очень доходчиво. Для понимания всего курса достаточно обладать общими знаниями C++, а также STL библиотеки. Курс позволяет глубоко понять концепцию построения игрового движка на OpenGL. Мне, как новичку, который начал учить C++ всего 3 месяца назад, очень нравится подача материала и возможность практиковаться, добавляя что-то своё. English: This course is excellent and the instructor explains everything very clearly. To understand the entire course, you just need general knowledge of C++ and the STL library. The course gives a deep understanding of the concept of building a game engine using OpenGL. As a beginner who started learning C++ only three months ago, I really appreciate the way the material is presented and the opportunity to practice by adding my own ideas.

This course explains most 3D game engine concepts which you'll also find in Unreal Engine, Unity, Godot and other mainstream engines. Indeed, there's no magic, all game engines do pretty much the same in essence - hide libraries and graphics APIs behind higher level abstractions. And here you'll learn exactly how to achieve that without getting into too much detail. Setup is a breeze and doesn't limit your dev environment. Code is easy to comprehend and follow. I'd like to see more modern C++ features at play, yet it's not a dedicated C++ course after all. Material is well structured. Complexity adds up gradually and when it's actually needed. Theory interventions are just enough to get solid understanding before you get bored. Overall, it packs a whole lot of hands-on experience. Perfect for beginners, those wondering how it works, or as a refresher.

Solid course, if you are ever interested how to make game engines from scratch, this course is really complete. It doesn't go far away into subtopics, and covers all primary features required by any game or 3D graphics project, and is good starting point if you want to start a carrer in game dev or 3D graphics. Physics is a great bonus, usually graphics courses are decoupled from physics, in this course it is covered all together. Also should mention pretty clear voice and speech spped of the tutor, very comfortable to understand. Big thanks to the author, wish you make more courses in that direction!

This course is a great way to start learning game development. It explains the basic ideas in a simple way, so it’s easy to follow even if you are new. I liked that there are many practical examples from real game engines. They help you see how things work in practice, not just in theory. The course is good for students and for anyone who wants to begin making games. The lessons are not tied to one engine, so you can use the knowledge in Unity, Unreal, or any other tool you choose.
