TuffX+

⚠️ WARNING:
This is not a "crack" for Minecraft, it simply allows for better TuffClient integration on servers.

TuffX+ is a single, unified plugin that combines:

Below Y0 [previousely TuffX] (Below Y0 support for modern world depth)
ViaBlocks (custom block palette + chunk updates for modern blocks)
ViaEntities (modern entity sync without nametags)
TuffActions (swimming sync + creative item handling + module restrictions)

Developers: Potato, UplandJacob, SyntaxSavy, llucasandersen, coleis1op

Installation

Requirements

Java 17+
Spigot/Paper 1.18+
ViaVersion and ViaBackwards (on the backend server only; not proxy)

PacketEvents, Jackson, and WebSocket libraries are shaded into the jar.

DO NOT install the old TuffX plugin; only this one

It is highly recommended to install AxSmithing for smithing table support (not specific to TuffClient) and ViaRewind for 1.7 - 1.13 support (including TuffClient).

Steps

Download the latest release from the Releases page (or the latest beta from the builds directory).
Drop TuffXPlus-x.x.x.jar into your server's plugins folder.
Start the server to generate plugins/TuffXPlus/config.yml.
Configure features in config.yml (y0, registry, viablocks, viaentities, swimming, creative-items, restrictions).
Restart the server or run /tuffx reload.

Features

Below Y0: sends extra chunk data for Y < 0 so TuffX client can see and interact with modern world depth.
ViaBlocks: synchronizes modern block states to TuffX client with a custom palette.
ViaEntities: syncs modern entities to TuffX client without nametags.
TuffActions: swimming state sync and creative item handling.
Restrictions: disallow TuffClient modules: module list
Optional server registry over WebSocket (for discovery).
