Sync Features

This page contains a list of the features HuskSync is and isn't able to syncrhonise on your server.

You can customise how much data HuskSync saves about a player by turning each synchronisation feature on or off. When a synchronisation feature is turned off, HuskSync won't touch that part of a player's profile; in other words, the data they will inherit when changing servers will be read from their player data file on the local server.

*Purpur's custom ender chest resizing feature is also supported.

†This is intended for servers that have mirrorred worlds across instances (such as RPG servers). With this option enabled, players will be placed at the same coordinates when changing servers.

PersistentDataContainer tags

The player PersistentDataContainer is a part of the Spigot API that enables plugins to set custom data tags to players, entities & items and have them persist. HuskSync will synchronise this data cross-server. Plugins that use legacy or propietary forms of saving data, such as by modifying NBT directly, may not correctly synchronise.

Custom enchantments

Plugins that add custom enchantments by registering them to ItemStacks through setting them via the EnchantmentStorageMeta will work, but note that the plugin must be lower on the load order than HuskSync; in other words, HuskSync should be on the plugin's loadbefore:. This is because Spigot's item serialization API requires that the plugin that registered the enchantment be online to serialize it due to how it reads from the enchantment registry and so if the plugin does not load before (and thus does not shut down after) HuskSync, it won't be able to serialize the custom enchantments in the event of a server shutdown with players online.

Map syncing

Map items are a special case, as their data is not stored in the item itself, but rather in the game world files. In addition to this, their data is dynamic and changes based on the updating of the world, something which can't be tracked across multiple instances. As a result, it's not possible to sync unlocked map items.

However, experimental support for synchronising locked map items—that is, maps that have been locked in a cartography table—is currently available in development builds. This works by serializing its' map canvas pixel grid to the map item's persistent data container.

Economy syncing

Although it's a common request, HuskSync doesn't synchronise economy data for a number of reasons!

I strongly reccommend making use of economy plugins that have cross-server economy balance synchronisation built-in, of which there are a multitude of options available. Please see our FAQs section for more details on this decision.

Toggling Sync Features

All synchronisation features, except location and locked map synchronising, are enabled by default. To toggle a feature, navigate to the features: section in the synchronisation: part of your config.yml file, and change the option to true/false respectively.

Example in config.yml

synchronization:
  # ...
  features:
    inventories: true
    ender_chests: true
    health: true
    max_health: true
    hunger: true
    experience: true
    potion_effects: true
