ItemCoreX

ItemCoreX

ItemCoreX is the core plugin I ended up building because I got tired of fake items, messy setups, and weird exploits.

A lot of servers work with items that look special, but in reality they are still just normal vanilla items with a custom name or lore.
That becomes a problem really fast once players rename items, try to fake them, or once shop systems only check the base material.

So instead of trusting how an item looks, ItemCoreX gives every custom item a real identity using PDC.

That means:

• renamed items do not become valid custom items
• fake-looking items do not bypass your systems
• custom items can safely use the same vanilla material without becoming a mess
• DeluxeMenus, FancyNPCs, drops, rewards and economy setups become much safer

What ItemCoreX is for

I made this for servers where items actually matter.

If you run:

• custom drops
• custom currencies
• server shops
• NPC rewards
• economy systems
• menu-based selling
• special event items

then ItemCoreX is meant to sit in the background and handle item identity cleanly.

No API work needed.
Everything works through commands, config files, placeholders and standard server plugin setups.

Main Features

• real custom item identity using PDC
• create and manage custom items with commands
• custom items can safely share the same vanilla material
• safe selling workflows for vanilla items
• PlaceholderAPI support
• pending / claim system for full inventories
• SQLite-based pending storage
• auto-claim on join
• join reminder for still pending items
• German and English language support
• configurable vanilla behavior flags

Why this matters

A normal plugin setup might only see something like BONE, EGG or CHARCOAL.

ItemCoreX checks what the item actually is.

So if you build a DeluxeMenus shop, mob reward system or NPC trade setup, the plugin can clearly separate:

• real vanilla items
• real ItemCoreX custom items
• renamed junk that only looks similar

That is the whole point.

PlaceholderAPI Support

ItemCoreX works well with PlaceholderAPI and can be used in other plugins like:

• DeluxeMenus
• FancyNPCs
• BossBar plugins
• Scoreboards
• HUD plugins
• Actionbar text systems
• other PlaceholderAPI-compatible setups

Examples:

%itemcorex_amount_<key>%
Shows how many ItemCoreX custom items with this key the player has in their inventory.
Useful for menu checks, trades, coupons, upgrades, and custom item sell menus.

%itemcorex_vanilla_amount_<MATERIAL>%
Shows how many real vanilla Minecraft items of this material the player has in their inventory.
ItemCoreX custom items are ignored, so vanilla sell menus stay safe.

%itemcorex_pending_total%
Shows the total amount of pending ItemCoreX items the player still has stored and can claim.
Useful for claim menus, NPCs, scoreboards, HUDs, bossbars, or actionbar messages.

%itemcorex_has_pending%
Shows whether the player has any pending ItemCoreX items waiting to be claimed.
Useful for claim buttons, menu conditions, NPC messages, or reminders.

%itemcorex_pending_<key>%
Shows how many pending items of a specific ItemCoreX item key the player has stored.
Useful if you want to display or check the pending amount of one exact custom item.

So if you want to display pending claims, custom item amounts, or safe vanilla counts in menus or UI systems, that is possible.

Full Inventory? No problem.

One part that was very important to me was safe item delivery.

If a player receives a custom item and their inventory is full:

• the part that fits is delivered
• the rest is saved safely
• the player can later use /ic claim
• pending items survive restarts
• auto-claim on join is supported
• join reminders are supported

That makes reward systems and mob drops much safer.

Works especially well with

• DeluxeMenus
• FancyNPCs
• PlaceholderAPI
• reward plugins
• mob drop systems
• economy-based server setups

In short

ItemCoreX is made for servers that want custom items done properly.

Not fake-looking items.
Not lore-only checks.
Not unsafe material-only selling systems.

Just real item identity, clean handling, safer menus, and better control over how custom items behave.

That is exactly why I made it.
