I watched Unreal part 1~3 a few years ago to learn Unreal C++. I came here after watching other Unreal lectures, and I wish I had watched this lecture sooner. You explain the core concepts well and make them easy to understand. It's good for people who have some knowledge of C++ and vectors, rather than those who don't know C++ and vectors at all. The instructor's many tips are hidden throughout, so if you focus and complete the course, you can gain a lot from this lecture.
