What impact do the project.h header file and the project.cpp file have on my project after a C++ project is created? And what effects can there be if variables, etc., are added to them?

It’s not recommended to use the project.h/.cpp files too much, as the engine offers many paradigms to add any and all lines that you would want to add there.

The way I understand it, these two files are ensured to be read early (as early as possible?) in the application lifecycle. Making them a good place to declare things that are both global and needed very early. The LogCategory that you show is actually a good example of that.

There should not be many reasons to add code or variables there, aside from engine stuff you have been specifically told to put there.
