SentryLore isn’t just about formatting items; it provides backend security systems and placeholder hooks to integrate deeply with your server network.

PlaceholderAPI Integration

SentryLore automatically hooks into PlaceholderAPI on server startup. You can use these placeholders in any supported plugin (like Scoreboards, Holograms, or Tablists) to display real-time SentryLore statistics.

%sentrylore_version%

Returns the currently installed version of SentryLore.

%sentrylore_total_items%

Returns the total number of custom items currently registered in the SentryLore database.

%sentrylore_player_toggled%

Returns Enabled or Disabled depending on the player’s personal lore visibility toggle.

Built-in Duplication Protection

One of SentryLore’s most powerful backend features is its strict Dupe Protection Engine. Because custom items can be highly valuable (like God Tier weapons), duping them is a severe threat to your economy. When a player receives a custom item through SentryLore, the item is tagged with a hidden, unique sentrylore_uuid in its PersistentDataContainer.
1

Inventory & Ground Scans

Every time a player joins the server, opens an inventory, or picks an item up off the ground, the DupeManager scans their entire inventory array in the background.
2

UUID Validation

The plugin keeps track of every sentrylore_uuid it encounters during the scan.
3

Silent Deletion & Logging

If the engine detects two custom items sharing the exact same UUID, it flags them as duplicated items. The duplicate is instantly and silently deleted, and an alert is sent directly to your configured Discord Webhook channel.
You can toggle Dupe Protection on or off via the dupe-protection.enabled setting in your config.yml. We highly recommend keeping it enabled for competitive survival and skyblock servers. We update consistently every patch and work very hard to fix bugs!
