ViaFabricPlus

Fabric mod to connect to EVERY minecraft server version (Release, Beta, Alpha, Classic, Snapshots, Bedrock) with QoL fixes to the gameplay

This project has nothing to do with the original ViaFabric and is therefore also not compact

Why?

ViaFabricPlus is supposed to be an alternative to multiconnect that offers more compactness and more clientside improvements, as ViaFabricPlus implements all Via platforms (ViaVersion, ViaBackwards, ViaLegacy, ViaAprilFools, ViaBedrock) and adds tons of clientside fixes and QoL improvements like old rendering for all platforms.

Backports

Basically there are no backports, the last version of ViaFabricPlus that supported a specific Minecraft version is also the last one that exists for that Minecraft version.
However, if a version between two Minecraft versions is too unstable, I will definitely make backports, you can find them only on modrinth/curseforge,
they do not have their own releases, current backports (named after their branch):

• 1.19.3

Settings and GUI

In the multiplayer screen you will find the ViaFabricPlus button in the upper left corner by default, it is the main button,
click on it, and you will see the Protocol selection, there you can choose the Minecraft version you want to connect to,
in the upper left corner you can go to the Settings.

In the Add/Edit Server screen there is a button where you can select a specific version for this server, when you ping or connect to this server,
ViaFabricPlus will use the version set there, the versions are stored in the servers.dat too

If you don't want to specify a specific version anymore, you can simply press the button and select "Cancel and reset".

Settings are optional settings that can turn fixes on and off, originally they were used for debugging

Bedrock edition

Keep in mind that the Java -> Bedrock support is still in beta phase, and therefore many things are not implemented
yet and there is no guarantee that everything will work as it should.

To log in to a Bedrock account you can press the button "Click to set account for Bedrock edition" in the settings,
then you can log in via device login, the account logged in there will be stored in ~/ViaFabricPlus/bedrock.account.

Classic stuff

Custom protocol extensions

ViaFabricPlus implements new Classic Extensions into the CPE protocol of ViaLegacy which are rather client side.

• WeatherType extension (version 1)

Protocol commands

To better control the Classic Protocol, there are a few clientside commands, the command prefix is /v:

• /vhelp - Displays all commands, available from: c0.28-c0.30
• /vsettime <Time (Long)> - Changes the Clientside World Time, available from: c0.28-c0.30
• /vlistextensions - Displays all classic protocol extensions, available in: c0.30 CPE

Alternatives

• ClientViaVersion: Discontinued 5zig plugin.
• multiconnect: Fabric mod for connecting to older versions: down to 1.11 (stable) and 1.8 (experimental).
• ViaFabric: Client-side and server-side ViaVersion implementation for Fabric

⚠️ WARNING ⚠️

I cannot guarantee that this mod is allowed on every (or even any) server. This mod may cause problems with anti cheat plugins. USE AT OWN RISK
