README

Русский

VBNetTweaks — это плагин для Valheim, который значительно улучшает сетевую производительность, синхронизацию объектов и стабильность многопользовательской игры. Мод оптимизирует отправку данных, сжатие трафика, синхронизацию позиций и работу с визуальными эффектами.

1. Оптимизация сетевой синхронизации

Патчит синхронизацию позиций и поворотов объектов:

Параметр	Vanilla значение	Новое значение	Описание
SmoothPos	0.2f	0.22f	Скорость сглаживания позиции (быстрее догоняет)
SmoothRot	0.5f	0.45f	Скорость сглаживания поворота
MicroThreshold	0.001f	0.004f	Фильтр микродрожания (уменьшает шум)

Дополнительно:

Увеличивает буфер очереди ZDO с 10KB до настраиваемого значения (по умолчанию ~20KB)
Расширяет время загрузочного экрана после телепортации на 5 секунд (Необходимо для устранения проваливания игроков в текстуры построек при телепорте - актуально для серверов с большим количеством игроков)

2. Синхронизация кораблей

Улучшенная синхронизация движения кораблей для не-владельцев:

Предсказание позиции корабля на основе скорости
Адаптивное сглаживание (мягче, если игрок на корабле)
Форс-коррекция при рассинхроне >2 метров или повороте >15 градусов
Синхронизация позиции игроков на корабле

3. Оптимизации Steam сокета

Увеличивает пропускную способность Steam Networking:

Параметр	Vanilla	VBNetTweaks (по умолчанию)	Описание
SendRateMin	150 KB/s	256 KB/s	Минимальная скорость отправки
SendRateMax	150 KB/s	4096 KB/s	Максимальная скорость отправки
BufferSize	260 KB	100 MB	Размер буфера отправки

4. Кеш игроков

Оптимизирует доступ к информации об игроках:

Кеширование списка всех игроков (обновление каждые 0.5 секунд)
Быстрый поиск игрока по ID
Отслеживание состояния прикрепления игроков (на корабле/транспорте)

5. Оптимизированная отправка ZDO

Заменяет ванильный метод SendZDOToPeers2 на более эффективный:

Отправка данных нескольким пирам за один апдейт (vanilla: 1 пир)
Конфигурируемый интервал отправки (vanilla: 0.05с)
Обработка ошибок с fallback на ванильный метод

6. Оптимизированное удаление объектов

Улучшает процесс удаления объектов из сцены:

Использует отметки кадров для быстрого определения объектов на удаление
Оптимизированная работа со словарями и списками

Overview

VBNetTweaks is a Valheim plugin that significantly improves network performance, object synchronization, and multiplayer stability. The mod optimizes data transmission, traffic compression, position synchronization, and visual effects handling.

1. Network Synchronization Optimization

Patches position and rotation synchronization of objects:

Parameter	Vanilla value	New value	Description
SmoothPos	0.2f	0.22f	Position smoothing speed (faster catching up)
SmoothRot	0.5f	0.45f	Rotation smoothing speed
MicroThreshold	0.001f	0.004f	Micro-jitter filter (reduces noise)

Additional features:

Increases ZDO queue buffer from 10KB to configurable value (default ~20KB)
Extends loading screen time after teleportation by 5 seconds (Necessary to eliminate players falling through the textures of buildings when teleporting - important for servers with a large number of players)

2. Ship Synchronization

Improved ship movement synchronization for non-owners:

Position prediction based on velocity
Adaptive smoothing (softer when player is on ship)
Force correction when desync >2 meters or rotation >15 degrees
Player position synchronization on ships

3. Steam Socket Optimizations

Increases Steam Networking throughput:

Parameter	Vanilla	VBNetTweaks (default)	Description
SendRateMin	150 KB/s	256 KB/s	Minimum send rate
SendRateMax	150 KB/s	4096 KB/s	Maximum send rate
BufferSize	260 KB	100 MB	Send buffer size

4. Player Cache

Optimizes access to player information:

Caching list of all players (updates every 0.5 seconds)
Fast player lookup by ID
Tracking player attachment state (on ship/vehicle)

5. Optimized ZDO Transmission

Replaces vanilla SendZDOToPeers2 with more efficient method:

Sends data to multiple peers per update (vanilla: 1 peer)
Configurable send interval (vanilla: 0.05s)
Error handling with fallback to vanilla method

6. Optimized Object Removal

Improves object removal from scene:

Uses frame markers for quick identification of objects to remove
Optimized dictionary and list operations

CHANGELOG

0.3.0

The compression was completely cut out (either it didn't work or it made it worse)
Updated patch for Steam
Fixed the module for synchronization on ships (it should get better at least in half of the cases)
The description has been corrected for the current version of the mod

0.2.9

The patch crutch for dummy effects has been removed
Deleting objects no longer intercepts the vanilla system
Compression is controlled by a single config, i.e. either to the server +client, or nowhere else.

0.2.8

The compressor has been redesigned. Now there's only one type. It should work more stably and stop visual dummies appearing.
The patch for Steam has also been simplified - the error on the Linux servers should be fixed.

0.2.7

Fixed compressor type synchronization

0.2.6

The RPCBatcer, ZDOTrotling, and ZoneOwner modules have been removed (essentially useless)
Steam patches are now being applied correctly
The configuration is syncing correctly with the server
ZSTD compression has been removed, as it is poorly compatible with Valheim, especially with mods
Added Vanilla compression - uses game compression, which is disabled by default
Added a patch to increase the ZDO buffer
Added a patch for ZSyncTransform for smoother interpolation (not included in the configuration)
The configuration settings are selected for the smoothest possible operation, as well as the vanilla values of the game.

0.2.4

Deleted AILod, MonsterAIPatch, and SupportManager because they are not related to the network component
Compression has been fixed - now it works both ways on the client and server

0.2.2

Half of the code has been redesigned
Almost all checks on the server/client have been removed
Some default settings have been changed for servers with online 40+

0.2.0

Split the compression switch. Now the server does compression by default, but the client does not do it by default, because it found that there is a problem with compression on the client (visual effects from status effects remain in the empty place where the mob was. For example, drops of water)
Added configuration synchronization. The main configuration is client-side. The synced config is located at "BepInEx\config\VitByr\VBNetTweaks"
The problem for Ubuntu servers should be fixed (from the previous version)

0.1.95

Adjusting configurations
Added the ability to disable modules - up to the entire mod. I need to restart the server and client, because I haven't done any synchronization yet.
A small fix for Spawn and AILod

0.1.9

cleaned the code from unnecessary comments and put it in order.
made the compression configuration more convenient for the ConfigurationManager (now you don't need to write in text - there will be a list)
added several additional checks for more stable operation

0.1.8

A small patch fix
Added Owner switching. If the Owner of an area with a bad ping and there is a player with a better ping in that area, then Ownership passes to that player. (Experimental)
The raid system has been changed. Now several raids are possible at the same time and they are not paused. (Experimental)
Added a config for setting the compression level

0.1.7

Add Incompatibility LeanNet
Add Incompatibility Scenic
Add Incompatibility NetworkTweaks
Add Incompatibility OpenSesame
Add Incompatibility Network
Add Incompatibility BetterNetworking
Add new config CompressionLevel
Add WearNTear Support Patch (Support checks are performed a little less frequently.)
