Struct bones_framework::time::Timer
source · pub struct Timer { /* private fields */ }
Expand description
Tracks elapsed time. Enters the finished state once duration
is reached.
Non repeating timers will stop tracking and stay in the finished state until reset.
Repeating timers will only be in the finished state on each tick duration
is reached or
exceeded, and can still be reset at any given point.
Paused timers will not have elapsed time increased.
Implementations§
source§impl Timer
impl Timer
sourcepub fn new(duration: Duration, mode: TimerMode) -> Self
pub fn new(duration: Duration, mode: TimerMode) -> Self
Creates a new timer with a given duration.
See also Timer::from_seconds
.
sourcepub fn from_seconds(duration: f32, mode: TimerMode) -> Self
pub fn from_seconds(duration: f32, mode: TimerMode) -> Self
Creates a new timer with a given duration in seconds.
§Example
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
sourcepub fn finished(&self) -> bool
pub fn finished(&self) -> bool
Returns true
if the timer has reached its duration at least once.
See also Timer::just_finished
.
§Examples
use std::time::Duration;
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
timer.tick(Duration::from_secs_f32(1.5));
assert!(timer.finished());
timer.tick(Duration::from_secs_f32(0.5));
assert!(timer.finished());
sourcepub fn just_finished(&self) -> bool
pub fn just_finished(&self) -> bool
Returns true
only on the tick the timer reached its duration.
§Examples
use std::time::Duration;
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
timer.tick(Duration::from_secs_f32(1.5));
assert!(timer.just_finished());
timer.tick(Duration::from_secs_f32(0.5));
assert!(!timer.just_finished());
sourcepub fn elapsed(&self) -> Duration
pub fn elapsed(&self) -> Duration
Returns the time elapsed on the timer. Guaranteed to be between 0.0 and duration
.
Will only equal duration
when the timer is finished and non repeating.
See also Stopwatch::elapsed
.
§Examples
use std::time::Duration;
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
timer.tick(Duration::from_secs_f32(0.5));
assert_eq!(timer.elapsed(), Duration::from_secs_f32(0.5));
sourcepub fn elapsed_secs(&self) -> f32
pub fn elapsed_secs(&self) -> f32
Returns the time elapsed on the timer as an f32
.
See also Timer::elapsed
.
sourcepub fn set_elapsed(&mut self, time: Duration)
pub fn set_elapsed(&mut self, time: Duration)
Sets the elapsed time of the timer without any other considerations.
§Example
use std::time::Duration;
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
timer.set_elapsed(Duration::from_secs(2));
assert_eq!(timer.elapsed(), Duration::from_secs(2));
// the timer is not finished even if the elapsed time is greater than the duration.
assert!(!timer.finished());
sourcepub fn duration(&self) -> Duration
pub fn duration(&self) -> Duration
Returns the duration of the timer.
§Examples
use std::time::Duration;
let timer = Timer::new(Duration::from_secs(1), TimerMode::Once);
assert_eq!(timer.duration(), Duration::from_secs(1));
sourcepub fn set_duration(&mut self, duration: Duration)
pub fn set_duration(&mut self, duration: Duration)
Sets the duration of the timer.
§Examples
use std::time::Duration;
let mut timer = Timer::from_seconds(1.5, TimerMode::Once);
timer.set_duration(Duration::from_secs(1));
assert_eq!(timer.duration(), Duration::from_secs(1));
sourcepub fn mode(&self) -> TimerMode
pub fn mode(&self) -> TimerMode
Returns the mode of the timer.
§Examples
let mut timer = Timer::from_seconds(1.0, TimerMode::Repeating);
assert_eq!(timer.mode(), TimerMode::Repeating);
sourcepub fn set_mode(&mut self, mode: TimerMode)
pub fn set_mode(&mut self, mode: TimerMode)
Sets the mode of the timer.
§Examples
let mut timer = Timer::from_seconds(1.0, TimerMode::Repeating);
timer.set_mode(TimerMode::Once);
assert_eq!(timer.mode(), TimerMode::Once);
sourcepub fn tick(&mut self, delta: Duration) -> &Self
pub fn tick(&mut self, delta: Duration) -> &Self
Advance the timer by delta
seconds.
Non repeating timer will clamp at duration.
Repeating timer will wrap around.
Will not affect paused timers.
See also Stopwatch::tick
.
§Examples
use std::time::Duration;
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
let mut repeating = Timer::from_seconds(1.0, TimerMode::Repeating);
timer.tick(Duration::from_secs_f32(1.5));
repeating.tick(Duration::from_secs_f32(1.5));
assert_eq!(timer.elapsed_secs(), 1.0);
assert_eq!(repeating.elapsed_secs(), 0.5);
sourcepub fn pause(&mut self)
pub fn pause(&mut self)
Pauses the Timer. Disables the ticking of the timer.
See also Stopwatch::pause
.
§Examples
use std::time::Duration;
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
timer.pause();
timer.tick(Duration::from_secs_f32(0.5));
assert_eq!(timer.elapsed_secs(), 0.0);
sourcepub fn unpause(&mut self)
pub fn unpause(&mut self)
Unpauses the Timer. Resumes the ticking of the timer.
See also Stopwatch::unpause()
.
§Examples
use std::time::Duration;
let mut timer = Timer::from_seconds(1.0, TimerMode::Once);
timer.pause();
timer.tick(Duration::from_secs_f32(0.5));
