andrew 4ebc4a2814 Throttle transform sends and smooth proxy movement
Separate normal transform send cadence from movement logging and improve proxy smoothing. Key changes:

- Polling/send logic (plugin/src/main.cpp): introduced distinct send vs log intervals (100ms send, 1s log), lowered send thresholds (≈3.0 units position, 0.02 rad rotation), renamed/clarified functions, and added special movement types (worldspace_change, cell_change, teleport) that bypass the send gate and are logged immediately. Normal movement targets roughly 10 Hz while moving to avoid packet-per-frame traffic.
- Proxy controller (plugin/src/F4TProxyActorController.cpp): tuned proxy position lerp alpha to 0.15 for smoother motion, renamed movement-interval variables for clarity, and removed the generic per-update movement gate so normal proxy visual updates are applied each game update while only the safety-offset path is throttled.
- Documentation updates (docs/architecture.md, docs/dev-log.md, protocol/player-sync.md): describe the new send/log separation, cadence and thresholds, smoothing behavior, and recorded dev-log about smoothing tests and results.

These changes reduce network noise, produce smoother remote visuals, and keep readable local movement logs while preserving immediate sends for large/categorical movement changes.

Fallout 4 Together

Fallout 4 Together is an experimental research project exploring the possibility of adding basic multiplayer-style networking to Fallout 4.

The goal is not to create a full co-op campaign mod immediately. The first goal is much smaller:

Two Fallout 4 clients in a controlled test environment, with each player visible as a synced remote actor.

This project is currently in the research and prototype stage.

Project Goals

First Prototype

  • Load a native Fallout 4 plugin through F4SE
  • Connect to a local test server
  • Send local player position data
  • Receive remote player transform data
  • Represent another connected player using a placeholder actor
  • Restrict all testing to a custom test cell

Long-Term Ideas

  • Basic LAN multiplayer test mode
  • Remote player movement sync
  • Basic animation state sync
  • Basic chat or debug messages
  • Host-controlled test cell
  • Simple co-op combat arena

Non-Goals

This project is not currently trying to support:

  • Full Fallout 4 campaign co-op
  • Quest synchronization
  • Settlement synchronization
  • Full NPC/world state synchronization
  • VATS synchronization
  • Public server/MMO gameplay
  • Compatibility with large modlists

Those systems are extremely complex and are outside the scope of the first prototype.

Requirements

This project is expected to require:

  • Fallout 4 on PC
  • Fallout 4 Script Extender, F4SE
  • Fallout 4 Creation Kit
  • Visual Studio 2022 or newer
  • CMake or another supported C++ build system
  • A CommonLibF4-based plugin template
  • Git
  • A clean Fallout 4 test profile

Use a separate Fallout 4 installation or a dedicated modding profile for testing.

Recommended setup:

Fallout 4
F4SE
Creation Kit
Mod Organizer 2 or Vortex
Visual Studio
Git

Use a clean test save and avoid testing with a full personal modlist.

This repository does not include Fallout 4 game files, Bethesda assets, F4SE binaries, or any proprietary game code.

Users are responsible for owning Fallout 4 and installing required external tools themselves.
