Presice rotate camera with springarm and PlayerController

Development Programming & Scripting

Hello,

I using spring arm for my Third Person Camera and I need to realize LookAt instant function, it should wok with working player Input. I have a function which calculates rotation very precise but looks like PlayerController AddYawInput and AddPitchInput function changes somewhere input I send:

void AThirdPersonCameraManager::CameraLookAtTargetInstantly(AActor* actor)
{
	if(actor == nullptr)
		return;

	ActorTarget = actor;

	// here we can check if action player camera is on

	// We have selected a new target. Compute desired rotation.
	FVector cameraLocation = GetCameraLocation();
	FVector targetLocation = actor->GetActorLocation();
	FRotator cameraRotation = GetCameraRotation();

	FRotator DesiredRotation = UCameraFunctionLibrary::CalculateLookAtRotation(cameraLocation, cameraRotation, targetLocation);

	PCOwner->AddYawInput(DesiredRotation.Yaw / PCOwner->InputYawScale);
	PCOwner->AddPitchInput(DesiredRotation.Pitch / PCOwner->InputPitchScale);
}

I have no active camera manager modifiers, so I don’t understand what’s wrong.

For example if I place AddYawInput(90.0f) - camera rotates only for 80+ degrees etc. Because of that I can’t calculate exact rotation speed to camera smooth move to look at.

For Yaw presice calculation of angle need an actor position - not camera, because for spherical coordinates we need angle with origin at center, but for Pitch same not works for some reason, I don’t know why - and it needs to be camera location.
