I want to know how to do basics things like creating a game class that has a Run/Init/StartGame function that I can override at the start so I can dynamicly load in the level and control the rendering without automatic frustum culling.
Unreal Engine 4 is super confusing because of too much going on behinde the scene and I have no idea where to add code.
You probably want to look at the UEngine class, which you can subclass and take control of the inner gameloop. You have to be careful because the editor also subclasses this class and your subclass won’t be avaiable. Also take a look at the FEngineLoop class and the GuardedMain function.
