ItemCoreX

ItemCoreX is the custom item system I ended up building because I got tired of fake items, messy setups and unsafe item handling.

A lot of servers use items that only look special through names or lore, but internally they are still just normal vanilla items.
That becomes a problem very quickly once players rename items, fake rewards or when menus and shop systems only check the base material.

ItemCoreX solves that by giving every custom item a real identity using PDC.

That means:

renamed vanilla items do not become valid custom items
fake-looking items cannot bypass your systems
custom items can safely use the same vanilla material
menus, rewards and economy systems become much safer
serialized items preserve their real appearance

🚀 ItemCoreX 2.0

Version 2.0 is a huge modernization update.

The plugin was heavily cleaned up internally and now focuses on a full GUI-first workflow instead of old command-heavy management.

✨ What's new in 2.0

Complete GUI overhaul
Full live item editor
Real 1:1 item previews
Better serialized item handling
Improved glow handling
Better inventory click handling
Cleaner language system
Cleaner internal architecture
Improved item consistency
Better startup/shutdown logger
Large cleanup of outdated systems

🖥️ Main GUI

GUI

The new GUI system makes item management much cleaner and easier.

You can now:

browse all registered items
search items directly in the GUI
edit items live
duplicate items
modify stack sizes
edit lore
manage glow effects
inspect serialized item previews

🎬 GUI Navigation

The GUI system was designed to replace most old command-heavy workflows.

🛠️ Item Editor

Editor

The item editor now supports:

live editing
real item previews
serialized item previews
lore editing
glow toggles
stack size editing
safer item handling

Serialized Items

Serialized items preserve the original Minecraft item exactly as it was created.

This includes:

display names
lore
enchantments
item flags
custom appearance
stored item meta

That allows ItemCoreX to keep real 1:1 item previews and original item behavior intact.

If you want to fully customize names and lore directly through the ItemCoreX editor, you can remove the serialized item data at any time inside the editor.

What ItemCoreX is for

I made this for servers where items actually matter.

Especially servers using:

custom drops
custom currencies
NPC rewards
menu shops
economy systems
event items
upgrade systems
reward crates

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

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

Main Features

real custom item identity using PDC
GUI-first item management
serialized item support
safe vanilla item selling
PlaceholderAPI support
pending claim system
SQLite-based pending storage
auto-claim support
join reminders
German and English language support
configurable vanilla behavior flags

Why this matters

A normal plugin setup might only see something like:

BONE
EGG
CHARCOAL

ItemCoreX checks what the item actually is.

So if you build:

DeluxeMenus shops
NPC trades
reward systems
mob drops
economy systems

the plugin can safely separate:

real vanilla items
real ItemCoreX items
renamed junk pretending to be custom items

That is the whole point.

PlaceholderAPI Support

ItemCoreX works well with PlaceholderAPI and plugins like:

DeluxeMenus
FancyNPCs
scoreboards
HUD plugins
bossbars
actionbars
menu systems

Examples:

%itemcorex_amount_<key>%
Returns the amount of a specific ItemCoreX item in the player's inventory.
Useful for DeluxeMenus checks, shop requirements, custom trades, upgrades and reward systems.

%itemcorex_vanilla_amount_<MATERIAL>%
Returns the amount of a real vanilla material in the player's inventory while ignoring ItemCoreX custom items.
Useful for safe vanilla sell menus, trade checks, buy requirements and economy setups.

%itemcorex_pending_total%
Shows the total amount of pending items.

%itemcorex_has_pending%
Shows whether the player still has pending items.

%itemcorex_pending_<key>%
Shows pending amounts for one exact custom item.

Full Inventory? No problem.

If a player receives items while their inventory is full:

fitting items are delivered
remaining items are stored safely
players can later use /ic claim
pending items survive restarts
join reminders are supported

This makes reward systems and custom drops much safer.

Works especially well with

DeluxeMenus
FancyNPCs
PlaceholderAPI
economy servers
custom reward systems
mob drop systems
menu-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, safer handling, modern GUI management and clean integration into existing server setups.
