andrew 89c3e82554 Implement proxy weapon animation sync for ranged guns
Milestone 1: Proxy actors now equip remote players' right-hand weapons and play armed idle/locomotion poses when weaponDrawn=true. Adds rightHand weapon slot to equippedItems protocol, weapon graph variable support (iSyncGunDown: 0=drawn, 1=holstered), and weapon FSM events (weaponDraw, readyStateEnter, gunDownStateEnter). Fixes two critical animation state churn bugs: frustum-visibility flicker no longer resets animation state on every update tick, and idle proxies no longer register as changed on every frame. Includes WeaponBehavior graph loading via AIProcess::RequestLoadAnimationsForWeaponChange() and manual weapon attachment fallback. New docs/weapon-animation-sync.md reference guide maps animation events and variables from F4-Animation-Research. Experimental alert-state reassertion for armed proxies to test NPC combat state gating of weapon-ready poses.

Protocol

This folder documents the planned network protocol for Commonwealth Online.

The first protocol should be simple and focused on player transform sync.

First Packet Types

  • Welcome packet
  • Transform packet
  • World state packet (host time and weather) — see world-state.md
  • Server world state packet (dev GUI weather/time) — see server-world-state.md
  • Disconnect packet

Future Packet Types

  • Animation state packet
  • Fire weapon packet
  • Health packet
  • Chat packet
  • Cell change packet

Design Goals

The protocol should be:

  • Simple
  • Easy to debug
  • Versioned
  • Safe to extend
  • Clear enough to test outside Fallout 4

Early Testing

The protocol should be testable using fake clients before being connected to Fallout 4.
