For those of you who use Mac: First, throw away Xcode and use Jetbrain's Rider, an Unreal engine IDE. (It seems better than Windows Visual Studio.) Just follow the settings as shown in the Unreal Editor video. I've already learned Unreal, but I'm weak in AI and UI, so I bought it and listened to it. It explains it in great detail. The voice is also at a speed that Koreans like(?). It would be good if you could organize the important parts in PDF or PPT. I'm going to watch Rookie's Direct 12 lectures and buy them. If you're only learning C++ courses, this course is much better than the courses on Udemy. Thank you for uploading such a good course at a low price. (It's much better than going to an academy.)
