A frame rate counter and tracker.

Required Methods

fn target_frame_rate(&self) -> f64

The target frame rate for the simulation.

fn target_time_per_frame(&self) -> FloatDuration

The target wall time for each frame.

fn remaining_frame_time(&self, time: &GameTime) -> FloatDuration

The duration remaining to reach the optimal frame time.

The duration can be negative if the current frame has executed longer than the optimal time.

fn tick(&mut self, time: &GameTime)

Update the counter for a new frame.

fn average_frame_rate(&self) -> f64

The average frame rate for the current frame.

fn is_running_slow(&self, time: &GameTime) -> bool

Return whether the simulation is running slowly.
