Struct EntityPositionSyncState 

pub struct EntityPositionSyncState {
    last_sent_position: DVec3,
    last_sent_on_ground: bool,
    sync_delay: i32,
}

Per-entity position sync state shared by player and entity tracking.

Fields

last_sent_position: DVec3

last_sent_on_ground: bool

sync_delay: i32

Implementations

impl EntityPositionSyncState

pub const fn new(position: DVec3, on_ground: bool) -> Self

Creates sync state at the position/on-ground state already known to clients.

pub const fn last_sent_position(self) -> DVec3

Returns the last absolute position used as the client’s delta base.

pub const fn last_sent_on_ground(self) -> bool

Returns the last on-ground state sent to tracking clients.

pub const fn sync_delay(self) -> i32

Returns the current delay since the last full position sync.

pub const fn advance_sync_delay(&mut self) -> i32

Increments the full-sync delay and returns the previous value.

pub fn position_changed(self, current_position: DVec3) -> bool

Returns whether current_position moved far enough to sync.

pub fn packed_delta( self, current_position: DVec3, ) -> Option<(PackedEntityDelta, PackedEntityDelta, PackedEntityDelta)>

Encodes the delta from the last sent position to current_position.

Returns None when any component overflows the protocol delta range and the caller must send a full position sync instead.

pub const fn mark_delta_sent(&mut self, position: DVec3, on_ground: bool)

Marks a delta movement packet as sent.

pub const fn mark_full_sent(&mut self, position: DVec3, on_ground: bool)

Marks a full position sync packet as sent and resets the full-sync delay.

pub const fn reset_base_without_packet( &mut self, position: DVec3, on_ground: bool, )

Resets the delta base when vanilla updates VecDeltaCodec without a packet.

pub fn record_movement_sync( &mut self, position: DVec3, on_ground: bool, force_full: bool, ) -> EntityPositionSyncDecision

Selects and records the next movement sync form.

Callers decide whether a sync is needed and whether vanilla forces a full sync for their tracking mode. This method owns the shared protocol delta overflow fallback and updates the sync base consistently.
