#include "MyActorFromC.h" // Sets default values AMyActorFromC::AMyActorFromC() { // Set this actor to call Tick() every frame. You can turn this off to improve performance if you don't need it. PrimaryActorTick.bCanEverTick = true; } // Called when the game starts or when spawned void AMyActorFromC::BeginPlay() { Super::BeginPlay(); } int AMyActorFromC::TestFunction(int a, int b) { int c = a + b; return c; } // Called every frame void AMyActorFromC::Tick(float DeltaTime) { Super::Tick(DeltaTime); }
