Following the C++ Video Series with UE 4.7

I noticed that in UE 4.7 when making an actor class the initial code that is created is completely different than that in UE 4.4. The 3rd Person Power-Up Game with C++ video series uses 4.4 to code a bunch of Actor classes, so how exactly do I follow the series with the change in 4.7 classes? What do I do with the new functions Tick and BeginPlay, which arent used in the video series? I also noticed that the constructor declaration is different in 4.7 vs 4.4.

i.e. ASpawnVolume::ASpawnVolume() vs
ASpawnVolume::ASpawnVolume(const class FPostConstructInitializeProperties& PCIP)

Actually, you can declare a default constructor with no parameters, but i prefer to use anyway the one with the object initializer.

Now the declaration is:
ASpawnVolume::ASpawnVolume(const FObjectInitializer& ObjectInitializer)
: Super(ObjectInitializer)
//init code

what would I do with the tick and begin play functions? Leave them blank?

If you don’t need them, you can always delete them, or leave them blank
