This is a well-structured lecture that makes it easy to understand Unreal Engine concepts and code together. At the beginning of the lecture, learning objectives were presented first to show which concepts to focus on, making it easy to set direction, and by separating concept parts and code parts in explanations, I was able to follow complex content without burden. Particularly in code explanations, rather than just simple usage, they pointed out why Unreal chose such structures, which helped understand the overall flow. Also, when difficult concepts appear, instead of jumping straight into code, they first organize concepts using PPT diagrams, then help you understand what role that part plays within the overall code flow. Thanks to this structure, it was easy to grasp what context the current learning content is in, and understanding the overall structure became faster. At the end, they provide a simple summary of the learned content, so it was good to reflect on which parts I focused on studying in connection with the initially presented goals. I recommend this lecture to those who want to understand Unreal's structure and operating principles together rather than simply following code.
