Lyra is an excellent Unreal Engine game sample. However, if you are unfamiliar with the underlying framework, GAS (Gameplay Ability System), it is difficult to properly grasp the many benefits Lyra offers. This course intuitively explains the fundamental elements of GAS and allows you to understand exactly how GAS works by building hands-on examples. I believe taking this course is the fastest way to master not only GAS but also the many features of Lyra that are not explicitly covered in the lectures.
