Introduce simple position smoothing for normal proxy movement and snap special movements. Adds kProxyPositionLerpAlpha, Lerp/LerpPosition helpers, and ShouldSnapRemoteMovement to lerp proxy position on normal updates while snapping on cell_change, worldspace_change, and teleport. Update MoveProxyToRemotePlayer to use lerp or snap, keep heading snapping (TODO: wrapped angle smoothing), and add throttled/readable logs for smoothing start, first smoothed movement, snaps, and idle-on-cell-mismatch. Minor messaging change on disconnect to leave proxy idle at last position. Update docs (architecture, setup, protocol) and dev log to reflect the new behavior and testing notes; dynamic spawning/multiple proxies remain out of scope.
Enable game-thread proxy actor movement driven by a copied remote-player snapshot and update related networking/validation, docs, and test client.
- Plugin: add F4T::ProxyActorController::Update() (alias UpdateSafetyTest preserved) and implement remote-state-driven movement for the single placed proxy (F4TProxyRemotePlayer01REF) in F4TTestCell01. Selects lowest available playerId, validates same-cell/worldspace for movement, and caches represented playerId. Adds helper functions (ParseHexFormId, IsRemotePlayerInSameLocation, SelectRemotePlayerToRepresent, MoveProxyToRemotePlayer) and improved throttled logging.
- Networking: tighten transform packet required-field checking (requires type, playerId, x, y, z, angleZ, cellId), add GetMissingRequiredTransformField, make movementType/worldspaceId/clientTime/serverTime optional with sensible defaults, and switch LogThrottledWarning to accept string_view.
- main.cpp: call ProxyActorController::Update on game-thread tasks.
- fake_client.py: mirror new packet validation and provide defaults for optional fields.
- Docs/dev-log/protocol/setup: update architecture, dev log, protocol, and setup notes to describe the single-proxy remote-state milestone, required packet fields, and testing checklist.
This change keeps networking thread limited to parsing/updating plain remote-player state and moves all actor access to the game-thread controller. Dynamic spawning, multiple proxies, and interpolation remain out of scope.
Add a networking receive loop and in-plugin remote-player storage. Introduces F4TRemotePlayerState (header + implementation) to track assigned playerId and remote player snapshots with thread-safe access. Expands F4TNetworking to start/stop a background receive thread, parse newline-separated JSON packets (welcome, transform, disconnect), validate fields, update remote state, throttle logs, and handle socket/thread synchronization. Add nlohmann_json to xmake and plugin build. Update docs and dev log to reflect the new receive behavior and current prototype scope.
Expand documentation to describe the current local networking prototype and its protocol. Adds a Current Architecture section and Fake Client responsibilities, clarifies that the Fallout 4 plugin currently only sends transforms (no receive loop yet), and documents implemented message types (welcome, transform, disconnect) with packet field descriptions and examples. Update player-sync and packets docs to reflect movementType, server/client timestamps, and the in-memory remote player state model used by server/fake_client.py. Flesh out server/README with run/test flow and implemented behavior. Revise dev-log with milestone entries, testing notes, and an entry template for future updates.
