How do you all manage character head movement?

The code supplied on the Oculus Rift Separate View page is is based on what Ground Branch uses for the Oculus Rift, Freeaim and Freelook.

It doesn’t matter if you use a camera attached to the player model or not, as the actual view rotation comes from by the player controller.

With a few changes, it can support anything you like - Rift, TrackIR, button & mouse based freelook etc.

For freelook, take the DeltaRot and apply it to the players view rotation instead of the controllers rotation.
Something like this:

    // Calculate Delta to be applied on ViewRotation
    FRotator DeltaRot(RotationInput);
 
    FRotator NewControlRotation = GetControlRotation();
    FRotator NewViewRotation = GetViewRotation();
    
    if (PlayerCameraManager)
    {
        if (bFreeLook)
        {
            PlayerCameraManager->ProcessViewRotation(DeltaTime, NewViewRotation, DeltaRot);
            
            // Limit how far we can turn our head before our torso begins to turn too.
            const float YawDif = FRotator::NormalizeAxis(NewAimRotation.Yaw - NewViewRotation.Yaw);
            const float MaxYawDif = 85.0f;
                
            float AddDeltaYaw = 0.0f;
            
            if (YawDif > MaxYawDif)
            {
                AddDeltaYaw = YawDif - MaxYawDif;
            }
            else if (YawDif < -MaxYawDif)
            {
                AddDeltaYaw = YawDif + MaxYawDif;
            }

            NewAimRotation.Yaw -= AddDeltaYaw;
            NewViewRotation.Yaw = FMath::ClampAngle(NewViewRotation.Yaw, NewAimRotation.Yaw - MaxYawDif, NewAimRotation.Yaw + MaxYawDif);
        }
        else
        {
            PlayerCameraManager->ProcessViewRotation(DeltaTime, NewControlRotation, DeltaRot);

            // We've stopped freelooking recently - reset the head angles.
            if (CenterHeadTime > 0.0f)
            {
                float Alpha = (TimeToCenterHead - CenterHeadTime) / TimeToCenterHead;
                CenterHeadTime = FMath::Max(0.0f, CenterHeadTime - DeltaTime);
                NewViewRotation = FMath::Lerp(NewViewRotation, FreeAim, Alpha);
            }
            else
            {
                NewViewRotation = NewControlRotation;
            }
        }
    }
 
    SetControlRotation(NewControlRotation);

    // If our view and aim are different, call SetViewRotation().
    if (NewViewRotation != NewAimRotation)
    {
        SetViewRotation(NewViewRotation);
    }

bFreelook, CenterHeadTime etc are set by a Freelook command, all within the player controller.

Hope it helps.

Thanks for the information, ! I hope you don’t mind if I ask a couple of questions regarding the link you provided (and more).

1. It lists files such as YourPlayerController.cpp (I realise is probably referring to just PlayerController.cpp) but I can’t seem to find it anywhere - is it in a particular folder? I had to physically go into the project folders to find Build.cs as Visual Studio couldn’t find it which I thought was weird.
2. Is there a way to toggle mode on and off or to have it has a ‘hold down to activate’? Just asking since that would be better since not has a headtracking device (hopefully buying a TrackIR next month and a OR DK2 a month or so after it is released).
3. Would you prefer to use a template (for example FPS or Third Person), or just start from scratch?
4. Finally, I imagine you would (I know I would) prefer to take the C++ route for the link you provided instead of the Blueprints route?

Thanks very much, !
