The problem is that there is not yet a lot of resource explaining how to interact with this class, so it may require a bit of reverse engineering to understand how to use its functionnalities. We are going to continue our C++ Fundamentals lessons by creating a custom HUD using AHUD class, then adding a custom widget to the HUD using UUserWidget and finally rounding things off by adding some UWidgetAnimations to make the whole thing look a bit more pretty.
