This bundle is marked as useful / simple. Simplicity is bliss, low effort and/or may contain minor bugs.
Simple system for simple maps.
Allows GUI users to easily create item carrying limitations with practically as many classifications as they want.
The code itself is in JASS but JNGP is NOT REQUIRED.
Implementation: (if you know JASS this should be self explanatory)
1. Copy the trigger ItemClassLimit and paste it amongst your map's triggers.
2. Make sure you have these 5 global variables in the map:
integer NumberOfItemClasses (default value 0)
integer array[1000] ItemClassId
integer array[1000] ItemClassLimit
string array[1000] ItemClassName
string array[1000] ItemClassErrorMsg
(The array size is not crucial, just make sure it's big enough. 100 is huge already.)
3. Register new item classes in separate trigger using GUI CustomScript
A new item class can be registerred with one simple CustomScript line.
example:
call NewItemClass( "MainHand Weapon", 1000, 1 )
This example would set up a class called MainHand Weapon, Item level to use as classification is 1000 and only 1 item can be carried by the same unit.
This system ONLY works with stardard war3 6 slot inventory.
Hopefully this will get approved even by the minimum standards so that it may help someone.
(I know this is quite simple, but as I made this for a request, I thought others might also have use for it.)

//===========================================================================
//======================== ITEM CLASS LIMIT =================================
//===========================================================================
//
// - This simple system allows user to limit the number of specific class of
// items one unit can carry.
//
// - ItemLevel is used as item class. So there can be thousands of custom
// item classes.
//
// - A new item class can be registerred with this function:
// call NewItemClass( "className", ItemLevelToUse, CarryingLimit )
//
// Example: call NewItemClass( "Main Hand", 1000, 1 )
// - After this, open Object Editor and set an item's level to 1000
// ( ! hold Shift while clicking ! )
// - Now your item is limited to 1 item per unit.
//
// - JNGP is NOT REQUIRED to use this. Normal WE work's just fine.
//
// - This only works with the standard WC3 inventory.
//
// - No need to give credits to anyone, feel free to edit.
//

It's not an inventory system per say. It's simply a quick way to limit carrying of certain types of items.

I like it, since he made it for a map I needed. And its so simple, I know hardly anything about JASS and I didn't need to use JASS at all. One simple trigger in GUI is all I ever had to edit.
EDIT:
This was intended for use with multiple players with multiple heroes, and I'm using it for multiple heroes for every player.
