Detailed Description

One snapshot's worth of interpolatable state.

PR-28: extended beyond (position, yaw) to also carry the inputs the client's CharacterAnimator needs each frame. Pre-PR-28 the renderer interp-delayed the entity's POSITION via this buffer while the animator continued to read the LATEST-snapshot Velocity

• pitch + PlayerVisState bits — so the animator was poseing at "now" while the body was rendered at "now − cl_interp". At 30+ ms render delay the running-vs-idle, walk-vs-sprint, and air-vs-ground flags would flip ahead of the visible motion, producing the 0.41-median anim-state delta the PR-27a telemetry caught. Storing the animator inputs here and sampling them at the same render time aligns body and pose.

Member Data Documentation

anim

AnimSnapshot InterpolationBuffer::Sample::anim {}

PR-29: server-authoritative animation state at this sample's tick.

Replicated via the Synced tuple, captured here per-snapshot so the renderer can render the body's interp-delayed pose with CharacterAnimator:: renderFromServer(buffered.anim, …) instead of letting the client's animator free-run and accumulate timeRatio drift against the server's authoritative animator.

captureNs

Uint64 InterpolationBuffer::Sample::captureNs = 0

SDL_GetTicksNS() at append time.

crouching

bool InterpolationBuffer::Sample::crouching = false

PR-28.

grounded

bool InterpolationBuffer::Sample::grounded = false

PR-28.

moveMode

std::uint8_t InterpolationBuffer::Sample::moveMode = 0

MoveMode enum cast (PR-28).

pitch

float InterpolationBuffer::Sample::pitch = 0.0f

Player pitch (rad, PR-28).

position

glm::vec3 InterpolationBuffer::Sample::position {0.0f}

World-space position.

sprinting

bool InterpolationBuffer::Sample::sprinting = false

PR-28.

velocity

glm::vec3 InterpolationBuffer::Sample::velocity {0.0f}

World-space velocity (PR-28).

wallRunSide

std::uint8_t InterpolationBuffer::Sample::wallRunSide = 0

WallSide enum cast (PR-28).

yaw

float InterpolationBuffer::Sample::yaw = 0.0f

Player yaw (rad). 0 for non-player entities.
