Having a problem with rotations (again)

Development Programming & Scripting C++

Heres the kicker.

This code doesnt work it stays 0-180-0 (or worse)


void UBPFuncLib_TDChelper::Bearing(const APawn* TgtShip, const APawn* PlyrSub, const UCameraComponent* ScopeCam, float &brgTrue, float &brgRel)
{

	if (TgtShip == nullptr || PlyrSub == nullptr || ScopeCam == nullptr)
		{
			debug("TgtShip or PlyrSub or ScopeCam == nullptr in BPFuncLib_TDCHelper::Bearing");
		}
		else
			{
			FVector LoS = (PlyrSub->GetActorLocation() - TgtShip->GetActorLocation()); //Line of sight from playersub center to target ship center
			LoS.Normalize();
			brgRel = FMath::RadiansToDegrees(FGenericPlatformMath::Acos(FVector::DotProduct(PlyrSub->GetActorForwardVector(), LoS))); //Bearing relative temp

			brgTrue = FMath::RadiansToDegrees(FGenericPlatformMath::Acos(FVector::DotProduct(FVector::ForwardVector, LoS))); //Bearing true from ForwardVector, is that north south?

					if (brgRel < 0)
					{
						brgRel = brgRel + 360.f 
					} 
					if (brgTrue < 0)
					{
						brgTrue = brgTrue + 360;
					}

			}
}

Note I also tried using the UCameraComponent.GetForwardVector/location/upvector.

But the blueprint equivalent does work the following is PERFECT. (top is perfect, bottom using the code node gives wrong result as above)

So I guess I must ask for a gimme to continue learning, how do I repdouce the tpo half of the blueprint picture in code?
