Hi! Really glad you guys are excited for the stream next week. 
We will upload the video afterwards to YouTube and you’ll be able to find it in our Live Training Stream Video Archive: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums. Source code will go up after each video so you’ll be prepared for the next video in the series, too.
Scrolling through the outline for the Udemy C++ course, I think we’ll definitely be covering different material, so no worries on that front. For our C++ tutorials, we generally try to build upon basic C++ knowledge of declaring classes, functions, and variables of basic data types with Unreal Engine-specific syntax and using the gameplay framework classes. The C++ course and these training streams should complement each other.
Tune in next Tuesday!
