AttributeFix Sync

AttributeFix Sync is an unofficial addon for the AttributeFix mod, designed to solve the synchronization issue where modified attribute limits on the server are not reflected on the client.

The Problem

In the original AttributeFix, if you modify the upper limit of an attribute (e.g., generic.max_health or generic.attack_damage) in the server configuration:

The Server correctly calculates damage and health based on your config (e.g., capped at 5000).
The Client still uses the default limit (e.g., 1,000,000).
Result: Mods like Jade, WTHIT, or the vanilla health bar display incorrect values because the client isn't aware of the stricter limit enforced by the server.

Features

This mod solves the above problem via packet synchronization:

Automatic Synchronization: When a player joins the server, the mod automatically sends all attribute limits (Max Values) configured on the server to the client.
In-Memory Patching: Upon receiving the data, the client dynamically modifies the attribute definitions in memory via Mixin.
Correct Visualization: Jade, WTHIT, and vanilla bars will now correctly display values based on the actual server limits.
Pollution-Free: When the player disconnects, the mod automatically restores the client's attribute limits to their original state, ensuring single-player worlds or other servers are not affected.

Installation & Usage

Dependencies

Minecraft: 1.21.1
Loader: NeoForge
Required Mod: AttributeFix

Usage

Server: Required. No configuration needed. It automatically reads the final values from AttributeFix and sends them to players.
Client: Required. Necessary to receive the synchronization packets.

Configuration

The client configuration file can be found at config/attributefixsync-client.toml.

Option	Default	Description
`enableSync`	`true`	Whether to accept attribute limit synchronization from the server.

Note: To change the actual attribute limits (e.g., max health), please edit the AttributeFix config files located in config/attributefix/.
