Make sure to add in your Project both PUBG_Basic.cpp and PUBG_CoreUObject_functions.cpp
If you want to use engine functions (You are internal, WHY WOULDN'T YOU! haha) add both PUBG_Engine_functions.cpp and PUBG_TslGame_functions.cpp as well
Don't forget to complete the function GetGlobalNames() in PUBG_Basic.hpp and the function GetGlobalObjects() in PUBG_CoreUObject_classes.hpp
