Struct amethyst_core::timing::Time

pub struct Time {
    pub last_fixed_update: Instant,
    /* private fields */
}

Frame timing values.

Fields

last_fixed_update: Instant

Time at which State::fixed_update was last called.

Implementations

impl Time

pub fn delta_seconds(&self) -> f32

Gets the time difference between frames in seconds.

pub fn delta_time(&self) -> Duration

Gets the time difference between frames.

pub fn delta_real_seconds(&self) -> f32

Gets the time difference between frames in seconds ignoring the time speed multiplier.

pub fn delta_real_time(&self) -> Duration

Gets the time difference between frames ignoring the time speed multiplier.

pub fn fixed_seconds(&self) -> f32

Gets the fixed time step in seconds.

pub fn fixed_time(&self) -> Duration

Gets the fixed time step.

pub fn frame_number(&self) -> u64

Gets the current frame number. This increments by 1 every frame. There is no frame 0.

pub fn last_fixed_update(&self) -> Instant

Gets the time at which the last fixed update was called.

pub fn absolute_time(&self) -> Duration

Gets the time since the start of the game, taking into account the speed multiplier.

pub fn absolute_time_seconds(&self) -> f64

Gets the time since the start of the game as seconds, taking into account the speed multiplier.

pub fn absolute_real_time(&self) -> Duration

Gets the time since the start of the game, ignoring the speed multiplier.

pub fn absolute_real_time_seconds(&self) -> f64

Gets the time since the start of the game as seconds, ignoring the speed multiplier.

pub fn time_scale(&self) -> f32

Gets the current time speed multiplier.

pub fn set_delta_seconds(&mut self, secs: f32)

Gets the total number of frames that have been played in this session. Sets both delta_seconds and delta_time based on the seconds given.

This should only be called by the engine. Bad things might happen if you call this in your game.

pub fn set_delta_time(&mut self, time: Duration)

Sets both delta_time and delta_seconds based on the duration given.

This should only be called by the engine. Bad things might happen if you call this in your game.

pub fn set_fixed_seconds(&mut self, secs: f32)

Sets both fixed_seconds and fixed_time based on the seconds given.

pub fn set_fixed_time(&mut self, time: Duration)

Sets both fixed_time and fixed_seconds based on the duration given.

pub fn increment_frame_number(&mut self)

Increments the current frame number by 1.

This should only be called by the engine. Bad things might happen if you call this in your game.

pub fn set_time_scale(&mut self, multiplier: f32)

Sets the time multiplier that affects how time values are computed, effectively slowing or speeding up your game.

Panics

This will panic if multiplier is NaN, Infinity, or less than 0.

pub fn finish_fixed_update(&mut self)

Indicates a fixed update just finished.

This should only be called by the engine. Bad things might happen if you call this in your game.

Trait Implementations

impl Clone for Time

fn clone(&self) -> Time

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Time

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Time

fn default() -> Time

Returns the “default value” for a type.

impl PartialEq<Time> for Time

fn eq(&self, other: &Time) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
