Hi, first i would like to apologize for my bad english since its not my nature language.
Im starting a project for a simple RPG map, and since its going to be an RPG i made use of a simple save/load system, and of a Inventory System.
After much time trying to figure it out i could finaly make both of them work, but there is a little problem, if a player would save the game, then remove its itens, give it to another player, and then the other player would save the game it could be a problem.
I made all of my itens unable to drop, but unfortunaly the inventory system has a problem, if you would remove the item, and your bag is full, it creates the item right at the side of your character.
Since im pretty bad at Jass and i spent a long long time looking for anything that could create one item beside the character but had no result, and after trying everything that i could do i finaly accepted that i cant do this so here i am looking for anyone that could help me with this.
All i want is that the system either blocks the removal of itens if the unit inventory is full, or if someone would remove an item and have a full inventory the item would be lost forever.
The system is :MUI Advanced Equipment System (+Save/Load +Event)
Code:
library AdvancedEquipmentSystem requires LinkedListModule, RegisterPlayerUnitEvent

    // The_Witcher's Equipment System
    //
    // This is my easy to use equipment system, which adds an equipment screen to any unit you want.
    //  equipped items can give up abilities to the owner and can change the animations of him...
    //
    //
    //       To learn how to use this system please read the "How To Use" delivered in the demo map
    //
    //
    // Requirements:
    //    JASS knowledge
    //    LinkedList (http://www.hiveworkshop.com/forums/jass-resources-412/snippet-linkedlistmodule-206552/)
    //    RegisterPlayerUnitEvent (http://www.hiveworkshop.com/forums/jass-resources-412/snippet-registerplayerunitevent-203338/)

Hi, first i would like to apologize for my bad english since its not my nature language.
Here is easy system of locking items.
P.S. This template makes soulbound only permanent items, consuamble items aren't soulbound, BUT you can change conditions.
Mechanism of the "soulbounding" who first picked the item then the item belongs to the owner of the hero-picker.

Unfortunaly i already tried that, and it didnt workd, because when the item is removed, i belive a new item is created, so it would not be bound to any player...
You can still bound it. I added the trigger "last created item lock". You may put it at the end of your trigger and try again.
