tick()

void MayaFlux::Vruta::FrameClock::tick ( uint64_t  forced_frames = 0 )

overridevirtual

Advance clock by computing elapsed frames since last tick.

Self-driven advancement: Calculates how much time has passed since last tick and advances frame count accordingly.

This is fundamentally different from SampleClock::tick(samples) which receives the sample count from external audio callback.

Called from graphics thread loop. Thread-safe for single writer.

Parameters

forced_frames

If non-zero, advances by this many frames instead of calculating from elapsed time. Used for testing or special cases.

Implements MayaFlux::Vruta::IClock.
