Problem with particle system and Collision Box

Hello !

I’m desperate right now : I want to make an energy source with a nice particle system which would heal my character if he steps on it. I created a collision box but nothing happens when he overlaps it :confused:

Here is my code :
SourceEnergie.h

#pragma once

class APersoPrincipal;

#include "GameFramework/Actor.h"
#include "SourceEnergie.generated.h"

UCLASS()
class GHOST_API ASourceEnergie : public AActor
{
	GENERATED_BODY()
	
public:	
	ASourceEnergie(const class FObjectInitializer& PCIP);

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Source)
		UParticleSystemComponent* Particules;

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Source)
		UBoxComponent* ProxBox;

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Source)
		UStaticMeshComponent* Mesh;

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Source)
		UAudioComponent* SonRendreVie;

	UFUNCTION(BlueprintNativeEvent, Category = Collision)
		void Prox(AActor* autreActor, UPrimitiveComponent* autreComp, int32 indexAutreBody, bool bFromSweep, const FHitResult & SweepResult);
	
};

SourceEnergie.cpp

ASourceEnergie::ASourceEnergie(const class FObjectInitializer& PCIP) : Super(PCIP)
{
	ProxBox = PCIP.CreateDefaultSubobject<UBoxComponent>(this, TEXT("ProxBox"));
	Particules = PCIP.CreateDefaultSubobject<UParticleSystemComponent>(this, TEXT("ParticleSystem"));
	Mesh = PCIP.CreateDefaultSubobject<UStaticMeshComponent>(this, TEXT("Mesh"));
	SonRendreVie = PCIP.CreateDefaultSubobject<UAudioComponent>(this, TEXT("Son"));

	RootComponent = Particules;

	ProxBox->OnComponentBeginOverlap.AddDynamic(this, &ASourceEnergie::Prox);
	ProxBox->AttachTo(RootComponent);
	Mesh->AttachTo(RootComponent);
	SonRendreVie->AttachTo(RootComponent);

}

void ASourceEnergie::Prox_Implementation(AActor* autreActor, UPrimitiveComponent* autreComp, int32 indexAutreBody, bool bFromSweep, const FHitResult & SweepResult)
{
	if (Cast<APersoPrincipal>(autreActor) == nullptr)
		return;

	APersoPrincipal *persoPrincipal = Cast<APersoPrincipal>(UGameplayStatics::GetPlayerPawn(GetWorld(), 0));
	persoPrincipal->setVie(persoPrincipal->getMaxVie());

	SonRendreVie->Play();
}

Thanks for your help !

Ok solved it, I created my blueprintclass before and my changes in my C++ class weren’t taken into account, I just had to delete the old Blueprint class and create a new one.
