SpawnActor won't work

Development Programming & Scripting C++

Hello!

I am trying to spawn a particle system when a projectile collides, but it won’t work; it doesn’t like the arguments.

Here’s my code:
In .h:


UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Category = Rendering)
	class UParticleSystem* OnHitPS;

In .cpp:



void ARSGameProjectile::OnHit(UPrimitiveComponent* HitComp, AActor* OtherActor, UPrimitiveComponent* OtherComp, FVector NormalImpulse, const FHitResult& Hit)
{
	UParticleSystem* ps = OtherActor->GetWorld()->SpawnActor<UParticleSystem>(OnHitPS,this->GetActorLocation());
}

And here is my error:

What am i doing wrong?

UParticleSystem is not an actor so you can’t use SpawnActor to instantiate it.
You should use this :


UGameplayStatics::SpawnEmitterAtLocation(this,OnHitPS, GetActorLocation(), GetActorRotation(), true);
