Super::BeginPlay();

Unreal Courses Ask
#1

Hello, I’m following the Unreal Engine C++ course and I’m half-way through the bull/cows game. Something that I’ve been wondering for a while is the purpose behind this line in the BeginPlay() function:

Super::BeginPlay();

What does it mean and why is it there?

Super is a type alias for the parent class (aka the super class). It is one of the things the GENERATED_BODY() macro does.

So for the UBullCowCartridge class it’s just an alias for UCartridge. So you are just calling the parent class’ BeginPlay function which does this

Does this mean that in the following…

void UBullCowCartridge::BeginPlay() 
{    
    Super::BeginPlay();

    SetupGame(); 
}

" Super::BeginPlay();" calls the BeginPlay() function in UCartridge, and then that UCartridge function (which also includes the line “Super::BeginPlay();”) then additionally calls the “virtual void BeginPlay()” function in ActorComponent.cpp?

Yes. It’s essentially extending the function.
