New op command to pretty-print a player's stored inventory from the DB.
Works on offline players — reads the serialized columns directly and
deserializes each slot through the same deserializeAndCreatePlaceholderIfNeeded
path used by the normal restore.
Usage:
/playersync inventory <player> — everything (main + armor + ender + curios)
/playersync inventory <player> main — 36-slot hotbar + main inventory only
/playersync inventory <player> armor — 4 armor slots (0=boots, 1=legs, 2=chest, 3=helm)
/playersync inventory <player> ender — 27 ender chest slots
/playersync inventory <player> curios — Curios slots (funct + cosmetic), composite-keyed
Output per section lists only non-empty slots:
[5] minecraft:diamond_sword x1
[8] sophisticatedbackpacks:backpack x1 (Gilded Backpack)
[cos🔙0] [placeholder] minecraft:paper x1 <- cross-server missing mod
Placeholder items (items from a mod not loaded on this server) are tagged
[placeholder] in magenta so admins can see at a glance which slots contain
'travelling' items. Parse errors on a single slot don't break the listing —
the affected slot shows <parse error: ClassName> and the rest continues.
Help listing updated. No other behavior changed.

PlayerSync
PlayerSync is a Minecraft Forge mod that synchronizes player data across multiple servers using a MySQL backend. It allows players to maintain their inventory, equipment, experience, advancements, and more when moving between servers in a network.
Mod Support
Any other mods support is also possible.
Development Setup
Database Setup (Docker)
A docker-compose.yml file is provided for easily setting up a MariaDB database instance for development testing.
- Make sure Docker is installed.
- Inside your work directory run:
This will download the MariaDB image (if not already present) and start a database container in the background.docker compose up -d - Stoppinng the Database
docker compose down
Data Persistence: The database uses a Docker volume, ensuring your data persists even if you stop and restart the containers.
Database Management Tool
The docker-compose.yml also includes an Adminer service, a lightweight database management tool.
- Access Adminer in your web browser at http://localhost:8080.
- Log in using the server with
- username:
playersync - database:
playersync - password: see docker-compose.yml
- username:
For debugging purposes, you can enable use_legacy_serialization to have readable database fields. This can cause crashes and unintended side-effects. Do not enable this on a production server if not absolutely necessary!
Running the Mod
The project uses Gradle for building and running. Use the provided Gradle wrapper (gradlew for Linux/macOS, gradlew.bat for Windows).
- Make sure that the MySQL database you configured is running.
- Run the Server
or on Windows:./gradlew runServer
This task compiles the mod and starts a dedicated Minecraft server instance with the mod loaded in the.\gradlew.bat runServerrundirectory. - Run the Client
or on Windows:./gradlew runClient.\gradlew.bat runClient
