Xbox One UWP Timescale messed up?

Hi,

we have a minute/second/hundreds counter in our game, working flawlessly on all devices. Except on the Xbox One when built as UWP. The time just speeds away several times faster than it should.

We're using UniRx, but that should not matter. Something makes time go faster on Xbox One S.

I recorded a short video showing the time UI going bananas: https://www.dropbox.com/s/iqpw5ok7erdshbp/IMG_0813.MOV?dl=0

Anyone have experience with this? Is it the Timescale that needs to be tweaked when publishing to XBox?


RaceModel.cs
=====
public LongReactiveProperty Time;
Time = new LongReactiveProperty();

RaceController.cs
=====
public void UpdateTime(RaceModel raceModel, long value)
{
raceModel.Time.Value = value;
}

RaceView.cs
=====
ViewModel.Time.Subscribe(OnTimeChanged).AddTo(gameObject);

void Update()
{
if (_stopwatch != null && _stopwatch.IsRunning)
{
_raceController.UpdateTime(ViewModel, _stopwatch.ElapsedTicks);
}
}

private void OnTimeChanged(long value)
{
_raceTimeText.text = DateTime.MinValue.Add(new TimeSpan(value)).ToString("mm\\'ss\\\"ff");
}

 

Hi,

cool, nice catch! Thanks, I learned something new.

A small rewrite, and it should be handled without the need to convert with Frequency:

RaceModel.cs
===
public ReactiveProperty<TimeSpan> Time;
Time = new ReactiveProperty<TimeSpan>();

RaceController.cs
=====
public void UpdateTime(RaceModel raceModel, TimeSpan elapsed)
{
raceModel.Time.Value = elapsed;
}

RaceView.cs
=====
ViewModel.Time.Subscribe(OnTimeChanged).AddTo(gameObject);

void Update()
{
if (_stopwatch != null && _stopwatch.IsRunning)
{
_raceController.UpdateTime(ViewModel, _stopwatch.Elapsed);
}
}

private void OnTimeChanged(TimeSpan elapsed)
{
_raceTimeText.text = DateTime.MinValue.Add(elapsed).ToString("mm\\'ss\\\"ff");
}
