EXCEPTION_ACCESS_VIOLATION when using RandomPointInBoundingBox method of KismetLibrary - c++

Question

I am facing an issue while generating a random point in a volume using KismetLibrary,
there is the code
#include "Spawner.h"
#include "Components/BoxComponent.h"
#include "Kismet/KismetMathLibrary.h"
#include "BaseCell.h"
// Sets default values
ASpawner::ASpawner()
{
// 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;
SpawningVolume = CreateDefaultSubobject<UBoxComponent>(TEXT("SpawnVolumeBox"));
RootComponent = SpawningVolume;
Cell = ABaseCell::StaticClass();
}
// Called when the game starts or when spawned
void ASpawner::BeginPlay()
{
Super::BeginPlay();
SpawnCells();
}
// Called every frame
void ASpawner::Tick(float DeltaTime)
{
Super::Tick(DeltaTime);
}
void ASpawner::SpawnCells()
{
if(Cell != NULL)
{
UWorld* const World = GetWorld();
if (World) {
FVector Origin = SpawningVolume->Bounds.Origin;
FVector Extent = SpawningVolume->Bounds.BoxExtent;
FVector SpawnLocation = UKismetMathLibrary::RandomPointInBoundingBox(Origin, Extent);
FRotator SpawnRotation;
SpawnRotation.Pitch = FMath::FRand() * 360.0f;
SpawnRotation.Roll = FMath::FRand() * 360.0f;
SpawnRotation.Yaw = FMath::FRand() * 360.0f;
ABaseCell* SpawnedCell = World->SpawnActor<ABaseCell>(Cell, SpawnLocation, SpawnRotation);
}
}
}
I should be able to generate without using Kismet the random point but i thought if this kind of library exists we should use them...
it's throwing the following error: https://i.stack.imgur.com/6nG45.png
EDIT
when trying to debug i figured that actually it's when i'm accessing private property "SpawningVolume" that error is thrown... still can't figure why
here is the Spawner.h
#include "BaseCell.h"
#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "Spawner.generated.h"
UCLASS()
class LIFE_API ASpawner : public AActor
{
GENERATED_BODY()
public:
// Sets default values for this actor's properties
ASpawner();
protected:
// Called when the game starts or when spawned
virtual void BeginPlay() override;
// Spawnable
UPROPERTY(EditAnyWhere, category="Spawning")
TSubclassOf<class ABaseCell> Cell;
public:
// Called every frame
virtual void Tick(float DeltaTime) override;
private:
// SpawningVolume as BoxComponent
UPROPERTY(VisibleAnyWhere, category="Spawning", meta=(AllowPrivateAccess="true"))
class UBoxComponent* SpawningVolume;
void SpawnCells();
};
EDIT 2
Just added this condition and it seems that "SpawningVolume" is "nullptr" so i don't know what i'm doing wrong but i keep investigating
void ASpawner::SpawnCells()
{
if(Cell != NULL)
{
UWorld* const World = GetWorld();
if (World) {
// Added condition
if (SpawningVolume != nullptr) {
FVector Origin = SpawningVolume->Bounds.Origin;
FVector Extent = SpawningVolume->Bounds.BoxExtent;
FVector SpawnLocation = UKismetMathLibrary::RandomPointInBoundingBox(Origin, Extent);
FRotator SpawnRotation;
SpawnRotation.Pitch = FMath::FRand() * 360.0f;
SpawnRotation.Roll = FMath::FRand() * 360.0f;
SpawnRotation.Yaw = FMath::FRand() * 360.0f;
ABaseCell* SpawnedCell = World->SpawnActor<ABaseCell>(Cell, SpawnLocation, SpawnRotation);
}
}
}
}
