Struct bevy_ecs::component::Tick

pub struct Tick { /* private fields */ }

A value that tracks when a system ran relative to other systems. This is used to power change detection.

Implementations

impl Tick

pub const MAX: Self = _

The maximum relative age for a change tick. The value of this is equal to crate::change_detection::MAX_CHANGE_AGE.

Since change detection will not work for any ticks older than this, ticks are periodically scanned to ensure their relative values are below this.

pub const fn new(tick: u32) -> Self

Creates a new Tick wrapping the given value.

pub const fn get(self) -> u32

Gets the value of this change tick.

pub fn set(&mut self, tick: u32)

Sets the value of this change tick.

pub fn is_newer_than(self, last_run: Tick, this_run: Tick) -> bool

Returns true if this Tick occurred since the system’s last_run.

this_run is the current tick of the system, used as a reference to help deal with wraparound.

Trait Implementations

impl Clone for Tick

fn clone(&self) -> Tick

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tick

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

Formats the value using the given formatter.

impl PartialEq for Tick

fn eq(&self, other: &Tick) -> 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.
