How It Works

PlayerSync uses a central MySQL or MariaDB database to store your player data. When you join a server, your data is loaded from the database. When you leave or your data is saved, it is updated in the database. This ensures your progress is always up to date, no matter which server you play on.

Getting Started

1. Install the Mod: Download the PlayerSync mod and place it in the mods folder of each server you want to synchronize.

2. Configure the Database: Generate config file by starting server at first.Edit the playersync.toml config file in the config folder to set your database connection details. Each server should have a unique Server_id.

3. Start Your Servers: PlayerSync will automatically create the necessary tables and keep your data in sync.

4. (Optional) Enable Chat Sync: Enable chat synchronization in the config if you want messages to be shared between servers.
