Struct game_time::framerate::counter::FrameCounter

pub struct FrameCounter<S: FrameRateSampler> { /* fields omitted */ }

A basic frame rate counter.

Methods

impl<S: FrameRateSampler> FrameCounter<S>

fn new(target_frame_rate: f64, sampler: S) -> FrameCounter<S>

Create a new FrameCounter with a target frame rate and sampler.

fn set_slow_threshold(&mut self, val: f64) -> &mut FrameCounter<S>

Set a new slow threshold.

fn slow_threshold(&self) -> f64

Return the current slow threshold.

If the current frame rate divided by the target frame rate is less than this value, then FrameCount::is_running_slowly will return true.

fn set_target_frame_rate(&mut self, val: f64) -> &mut FrameCounter<S>

Set the target frame rate.

fn is_saturated(&self) -> bool

Return true if the sampler is saturated.

fn sampler(&self) -> &S

Return a reference to the sampler object.
