Ajuda com valor Y da Window_ItemCategory

[JF]

Boa noite galera,

Estou estudando os códigos dos plugins que encontrei aqui, neste caso, um plugin do Yanfly.

Alterei as propriedades das windows do game e consegui praticamente todas, menos o da scene item. Não consigo achar uma maneira de definir o valor Y da Window_ItemCategory , já tentei criar um novo método mas só buga as windows restantes.

Aqui o código que estou usando:

//=============================================================================
// Yanfly Engine Plugins - Item Core
// YEP_ItemCore.js
//=============================================================================

var Imported = Imported || {};
Imported.YEP_ItemCore = true;

var Yanfly = Yanfly || {};
Yanfly.Item = Yanfly.Item || {};
Yanfly.Item.version = 1.26;

 * ============================================================================
 * Introduction
 * ============================================================================
 *
 * This plugin makes a couple of main changes to your game and the way items
 * are handled to allow a base core for future plugins.
 *
 * 1. Independent Items
 * If you choose to have maximum limit on your items, weapons, and/or armors,
 * those items will become independent and have their own individual stats and
 * whatnot. Independent items are capable of being upgraded, altered, modified,
 * etc. and retain those changed properties independent of other items of the
 * same type. Items without a maximum limit (aka 0), will continue working as
 * they normally did in RPG Maker MV.
 *
 * 2. New Scene_Item
 * The item scene has been revamped to look a little bit different. With the
 * new layout, the item list is no longer two columns, but one. Added are a few
 * more windows, such as the item status window (which displays basic item
 * information), an item information window (which shows information applied to
 * the item via upgrades, etc.), and an item action window, which appears when
 * you select an item and it will ask you if you wish to Use the item or any
 * action added via plugins (such as upgrading the item). If you wish to not
 * use this revamp, you can disable it from the parameters.
 *
 * 3. Random Variance
 * Newly acquired items that aren't from shop can be given randomized stats to
 * a small degree for items that are independent. Items can be above the stock
 * value or below the stock value by the variance value. If you wish for an
 * item to not have a variance value, you can use a notetag to set the variance
 * value to 0. If you wish for all of your items to not have a variance value,
 * you can set the parameter to 0.
 *
 * Note: During battle test, independent items are disabled.
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 *
 * If you are using independent items, items that aren't gained through the
 * shop can have a random variance applied to its stats.
 *
 * Item, Weapon, Armor Notetag
 *   <Random Variance: x>
 *   If this item is acquired through non-shop means, it will have random
 *   stats offset by x amount in either a positive or negative value.
 *
 *   <Not Independent Item>
 *   Sets an item that is independent by default to become a nonindependent
 *   item, allowing it to stack and making it unable to be affected by
 *   independent item modifiers.
 *
 *   <Priority Name>
 *   This sets the item, weapon, or armor's priority name to its database
 *   entry so that name schemes cannot affect the item.
 *
 *   <Text Color: x>
 *   This sets the text color of this item, weapon, or armor to use text color
 *   x from the window skin.
 *
 * ============================================================================
 * Plugin Commands
 * ============================================================================
 *
 * If you wish to be able to add items to your player's inventory without the
 * random variance being applied to it, you can use the following plugin
 * commands to adjust the settings for that.
 *
 * Plugin Command:
 *   EnableVarianceStock  - Causes all items acquired from this point forward
 *                          to have its variance give stock (nonrandom) values.
 *   DisableVarianceStock - Causes all items acquired from this point forward
 *                          to have its variance give random values.
 *
 * A small note is that if you enabled the variance stock values, if the player
 * restarts the game by either going through the title screen or just turning
 * off the program and starting it back up, the random variance will be in
 * effect again. This plugin command is meant to exist as a short term disable.
 *
 * ============================================================================
 * Eventing Changes
 * ============================================================================
 *
 * A few changes have been made to eventing in order to adjust for independent
 * items. They are as follows:
 *
 * Event Page Conditions and Conditional Branches:
 *   Checking to see if an item exists in the party's inventory will differ if
 * the item can be independent. Instead, the condition can be fulfilled if
 * there is an item, even when upgraded, that has the selected item as the base
 * item. This means your Long Sword (+1) will fulfill the condition of having
 * the target Long Sword item in the event editor.
 *
 * Actor Has X Equip:
 *   Just like the previous condition, this condition will be fulfilled if the
 * actor has a weapon whose base item matches the event editor's target item.
 * The Long Sword (+1) will fulfill the condition of needing the actor to have
 * a Long Sword item equipped.
 *
 * Change Equipment:
 *   If the target equipment is independent, the game will first check to see
 * if the actor has an item equipped with the matching base item. If not, the
 * game will then check to see if the party has a matching base item in the
 * inventory first and use that. If not, then the game will create a new stock
 * version of the item and equip that to the actor.
 *
 * ============================================================================
 * Item Name System
 * ============================================================================
 *
 * For independent items, they have a unique name handling system. Independent
 * items consist of four parts:
 *
 *      Prefix     Base Name     Suffix     Boost Count
 *
 * The prefix, base name, suffix, and boost count are adjusted by plugins.
 * Depending on the effects applied, they can be altered or changed. Using the
 * name system, an item with a prefix of 'Fiery', base name of 'Sword', suffix
 * being 'of Might', and a boost count of 5 will end up looking like:
 *
 *      Fiery Sword of Might (+5)
 *
 * This item would appear that way only if its various name parts have been
 * altered some way or another. However, there is a fifth name convention, and
 * that is the priority name. If an item has a priority name, it will completely
 * overwrite the current name scheme with just the priority name itself. So even
 * if the item's name is 'Fiery Sword of Might (+5)', if the item's priority
 * name is 'Legendary Blade', then 'Legendary Blade' will take priority.
 *
 * ============================================================================
 * Lunatic Mode - On Independent Item Creation
 * ============================================================================
 *
 * For those with JavaScript experience, you can use the following Lunatic Mode
 * to run JavaScript code upon the creation of the item. This only applies to
 * newly made independent items.
 *
 * Item, Weapon, Armor
 *
 *   <On Creation Eval>
 *    item.price = baseItem.price;
 *    item.price += Math.floor(Random() * 100);
 *   </On Creation Eval>
 *   The 'item' variable refers to the independent item being made. 'baseItem'
 *   refers to the item's base item. Any alterations made to the 'item' will be
 *   applied to the independent item.
 *
 * ============================================================================
 * Lunatic Mode - Custom Info Window Display
 * ============================================================================
 *
 * If you want to display unique and custom stuff into your info window on the
 * side, you can use the following notetags:
 *
 *   <Info Text Top>
 *    text
 *    text
 *   </Info Text Top>
 *   Type in extra information you wish to type in for the item info window
 *   here, whether it is lore or other information. Text codes can be used.
 *   Information here is is displayed towards the top of the info window.
 *
 *   <Info Text Bottom>
 *    text
 *    text
 *   </Info Text Bottom>
 *   Type in extra information you wish to type in for the item info window
 *   here, whether it is lore or other information. Text codes can be used.
 *   Information here is is displayed towards the bottom of the info window.
 *
 *   <Info Eval>
 *    var variableId = 1;
 *    var value = 500;
 *    $gameVariables.setValue(variableId, value);
 *   </Info Eval>
 *   If you know JavaScript, you can use these notetags to run some code before
 *   displaying any new info. This way, if you plan on using text codes that
 *   display variable values, you can run a bit of code before displaying them
 *   to synch up what's shown in the item info window.
 *
 * ============================================================================
 * Independent Items and Midgame Note Parsing
 * ============================================================================
 *
 * The "Midgame Note Parsing" option in the plugin parameters is made for any
 * plugins that may only parse notetags midgame as opposed to at the loading of
 * the game. This is an option that you should enable AT YOUR OWN RISK.
 *
 * Why is it at your own risk? Because enabling this option means independent
 * items will keep their notedata, thus, increasing the file sizes of your save
 * files several times bigger, and it can cause lag midgame, too.

Ham... dei um Ctrl + F nesse script e ele não altera a posição da janela que tu tá querendo.
Tu pode dar uma olhada na linha 1045 do rpg_scenes. Por lá está a função que cria ela e tem uma linha definindo o y.
