In UE4 programming quick start example to make a cone goes up and down,
float RunningTime
is added to FloatingActor.h and in FloatingActor.cpp, this RunningTime is used with DeltaTime as
RunningTime += DeltaTime
How does RunningTime get initialised to zero in the .h file ? It is not explicitly put equal to zero and is not added inside AActor or its derived class constructor.
Would be appreciated if can help.
