Struct ViewHistory 

pub struct ViewHistory { /* private fields */ }

The entities sent to one subscriber over the last ticks, as its interpolator holds them. See the module docs.

Implementations

impl ViewHistory

pub fn new(keep_ticks: u64) -> Self

Keep enough to place entities at ticks down to keep_ticks before the newest frame.

pub fn keep_ticks(&self) -> u64

How many ticks back position_at can see.

pub fn last_tick(&self) -> Option<u64>

The newest tick recorded.

pub fn clear(&mut self)

Forget everything (a new connection, or the subscriber’s baseline was reset).

pub fn record( &mut self, tick: u64, precision: f32, full: bool, spawned: &[Sent], updated: &[Sent], despawned: &[EntityId], )

Record a frame sent for tick. full is a frame that lists every entity the subscriber has, as spawned. Positions are quantized; the subscriber places them at q * precision.

pub fn position_at(&self, id: EntityId, render_tick: f64) -> Option<[f64; 3]>

Where the subscriber drew id at render_tick (fractional), or None when the subscriber did not draw it then (not spawned yet, despawned, or never sent).

pub fn entities_near( &self, center: [f64; 3], radius: f64, render_tick: f64, ) -> Vec<(EntityId, [f64; 3])>

Every entity the subscriber drew at render_tick within radius of center (3D distance), with its position then, in id order.

pub fn ids(&self) -> impl Iterator<Item = EntityId> + '_

Ids the history holds a life for (open or recently ended).
