//=============================================================================
// Maliki's YF Item Core Extension - Changable Instance Item Maxes
// Mal_ItemCore_Ext_Changable_Max.js
// version 1.0
//=============================================================================
/*:
 * @plugindesc ver1.0 - Allows you to change the Max number of Instance Items, Weapons, or Armors in game.
 * @author Maliki79
 *
 * @help For maximum compatibility, put this plugin DIRECTLY UNDER YF'S ITEM CORE PLUGIN!
 * In order to use this plugin, you simply have to make the following script calls:
 *  $gameParty.changeInstItemMax(x);
 *  $gameParty.changeInstWeaponMax(x);
 *  $gameParty.changeInstArmorMax(x);
 * With x being an integer.
 *
 * Also, make sure you have the item category set to feature instance items from the original plugin's parameters, or you may cause a crash.
 * Note that using this plugin, you can put a negative value reducing the amount of Instance Items in a category.
 * For the most part there shouldn't be any issues, but make sure not to set the amount so that the items number goes below 1.
