Calling Interface function not working

I’m rather confused on how to utilize interfaces in CPP. The wiki gives goes pretty in-depth but for some reason does not include how to call interface functions.

IInteractableInterface.h

public:
	UFUNCTION(BlueprintNativeEvent, BlueprintCallable)
	void OnInteract();
};

GunBase.h

virtual void OnInteract_Implementation() override;

GunBase.cpp

void AGunBase::OnInteract_Implementation()
{
	IInteractableInterface::OnInteract_Implementation();

	GetWorld()->RemoveActor(this, true);
	UE_LOG(LogTemp, Warning, TEXT("INTERACTED W/ GUN"));
}

Character.cpp

if (Hit.GetActor()!=nullptr && Hit.GetActor()->Implements<UInteractableInterface>())
	{
		IInteractableInterface* IntFace = Cast<IInteractableInterface>(Hit.GetActor());
		IntFace->Execute_OnInteract(Hit.GetActor());
		UE_LOG(LogTemp, Warning, TEXT("Actor %s"), *Hit.GetActor()->GetName());
	}

And running the game and interacting with the gun results in this log message

LogTemp: Warning: Actor BP_SMG01_C_UAID_00D861193EC68E6501_2092153807

Which tells me that interact is running the line trace and returning the result of the Gun, which does implement the interface, but does not call the Gun’s OnInteract function. What am I doing wrong exactly?

er… try IInteractableInterface::Execute_OnInteract(Hit.GetActor())

I think that’s how that’s supposed to work, as a static call, rather than an instance call.

Seems to produce the same output, still the same problem unfortunately.

Breakpoint into it, and see where it’s going?
