PrimaryActorTick.bCanEverTick = true;
}
void AItem::BeginPlay()
{

}
void AItem::Tick(float DeltaTime)
{
Super::Tick(DeltaTime);

	//movement rate in units of cm/s
	float movement_rate = 50.f;
	UE_LOG(LogTemp, Warning, TEXT("Hello!!"));

	//movement rate* deltatime (cm/s) * (s/frame) = cm/frame
	AddActorWorldOffset(FVector(movement_rate * DeltaTime, 0.f, 0.f));
	DRAW_SPHERE_SF(GetActorLocation());

You need:

SetComponentTickEnabled(true);

You override BeginPlay but are missing Super::BeginPlay(). I believe this can even affect tick.

You can do it in constructor or somewhere else if you want an object to only Tick() at certain times.

As an example several projects I’ve worked on actors only Tick() when they are moving or animating.
