You can easily find info on function pointers on the internet, but in UE4 classes you need to also specify the namespace, and I was having trouble with that part. With our demo app we needed to start with iOS view controllers and go back to Unreal Engine, starting and stopping the scene/level.

If you don't know or don't want to mess around with code and deal with C++, choose Blueprint. Calling Blueprint-defined interface functions from C++ While the previous recipes have focused on C++ being usable in Blueprint, such as being able to call functions from C++ in Blueprint, and override C++ functions with Blueprint, this recipe shows you the reverse: calling a Blueprint-defined interface function from C++. I develop interactive applications, systems and games using Unity3d and Unreal Engine 4. The spine-ue4 runtime wraps the spine-cpp structs and functions and exposes them in both code and as Unreal Engine Blueprints. This tutorial was created in Unreal Engine 4. Brenden Sewell does a good job of introducing game development concepts in a series of chapters which build upon the same project, culminating in a nice (if somewhat simple) demo at the end. The general usage pattern is the same for either. She said industry leaders who are contemplating getting their businesses out of China are 'definitely considering India is the pitch'. UE4 provides two methods, C++ and Blueprint Visual Scripting, to create new gameplay elements. This is the first step to start creating your own games and projects, and to begin to understand the Unreal Engine. UE4 C++ does not support abstract classes and virtual functions like regular C++; UE4 macros are necessary to create a pseudo abstract class and pure virtual function Need to use the macros: uclass (abstract) and PURE_VIRTUAL; Note: Pure virtual functions are technically not possible since UE expects every UE class to be instantiable (non-abstract). Neither strictly a publication nor a marketing firm, it provides salient, entertaining stories that serve the dual purposes of disseminating new ideas and promoting the brands that are most often the focus of its stories. Unreal Engine uses the concept of a Nav Area for this.
