ludus::foundation::time::FrameClock¶

Class

Sample once per frame and pass the result by value.

Reset at startup, pause, resume, suspension and session replacement. First sample yields zero elapsed. Maximum delta is application policy; zero deliberately freezes accepted time. A backwards sample yields zero and retains the previous high-water mark, so recovery cannot count the same interval twice. Equal samples are accepted.

Methods¶

FrameClock¶

explicit ludus::foundation::time::FrameClock::FrameClock(Duration maximumDelta) noexcept

Configure the accepted delta cap in nanoseconds; zero freezes accepted elapsed time.

Reset¶

void ludus::foundation::time::FrameClock::Reset() noexcept

Forget the previous sample; the next Sample establishes a zero-duration baseline.

Sample¶

FrameSample ludus::foundation::time::FrameClock::Sample(Timestamp now) noexcept

Sample elapsed time, retaining the high-water mark on regression and reporting clamp loss.
