SetFocalPoint() not setting correct Pitch

Development Programming & Scripting C++

I am writing an AI for an FPS game. To set aim, I am using


SetFocalPoint(Enemy->GetActorLocation())

in the AIController class. However it is not setting the correct pitch of the controller. When I use


SetFocus(Enemy)

it works fine. Am I missing something?

I found the solution. The method UpdateControlRotation() in AIController ignores the pitch if the target is not pawn



void AAIController::UpdateControlRotation(float DeltaTime, bool bUpdatePawn)
{
    APawn* const MyPawn = GetPawn();
    if (MyPawn)
    {
        FRotator NewControlRotation = GetControlRotation();

        // Look toward focus
        const FVector FocalPoint = GetFocalPoint();
        if (FAISystem::IsValidLocation(FocalPoint))
        {
            NewControlRotation = (FocalPoint - MyPawn->GetPawnViewLocation()).Rotation();
        }
        else if (bSetControlRotationFromPawnOrientation)
        {
            NewControlRotation = MyPawn->GetActorRotation();
        }

        //** Don't pitch view unless looking at another pawn**
        if (NewControlRotation.Pitch != 0 && Cast<APawn>(GetFocusActor()) == nullptr)
        {
            NewControlRotation.Pitch = 0.f;
        }

        SetControlRotation(NewControlRotation);

        if (bUpdatePawn)
        {
            const FRotator CurrentPawnRotation = MyPawn->GetActorRotation();

            if (CurrentPawnRotation.Equals(NewControlRotation, 1e-3f) == false)
            {
                MyPawn->FaceRotation(NewControlRotation, DeltaTime);
            }
        }
    }
}

So if you want the pitch to be applied, simply override the method in the child class! Dunno why it ignores the pitch by default.

earlier I had a lot of problems with focal point and focus on an actor, as I remember you need to set nullptr to focus then you can use focal point properly…
