//=============================================================================
 /*:
 * @plugindesc <WeaponSwap> for RPG Maker MV version 1.6.1.
 * @author Fallen Angel Olivia
 *
 * @help
 * This is a RPG Maker MV plugin that will give your game's actors the function
 * to swap weapons in the middle of the fight. Up to one of each weapon type
 * can be equipped at a time and they can be switched out each turn. Swapping
 * weapons can let the player team adapt to certain situations better or giving
 * them the ability to hit certain weapon weaknesses in battle.
 *
 * This plugin changes both something inside battle and outside of battle.
 * The Attack command option can now have the weapon being used swapped by
 * pressing left or right (if that option is turned on). Some skills can also
 * automatically switch to a weapon when it starts being used.
 *
 * The other change is in the Equip menu. Instead of having only a single
 * weapon slot, there is now one weapon slot for each of the weapon types.
 * Each actor can equip a weapon of that type into those slots if they can use
 * those weapon types.
 *
 * There will be a warning though. This feature does not work with the
 * Dual Wield system so it is disabled in order to be able to swap weapons.
 *
 * Some plugin parameters require your attention. Please read through and
 * configure them to customize weapon swapping for your game.
 *
 * -----------------
 * Plugin Parameters
 * -----------------
 *
 * Battle Control:
 *
 * Swap Command: How command for how Weapon Swap is displayed
 *
 * Show Command?: Show the Weapon Swap Command in the Actor Command Window?
 * Turn this on if you are making your game for mouse control because there
 * is no other way to switch weapons without using the arrow keys.
 *
 * Use Arrow Swapping?: Use Arrow Keys to control weapon swapping? If on,
 * then pressing left or right will switch the weapon currently equipped
 * in the order of the Weapon Types list in the Database's Types tab.
 *
 * Show Swap Arrows?: Shows arrow sprites next to the Attack command to tell
 * the player that pressing Left or Right here can have an effect.
 *
 * Battle Test Weapons: During battle test, equip each party member with one of
 * each weapon type. The weapon selected will be the first available one in the
 * database unless they already have that weapon equipped.
 *
 * Visuals:
 *
 * Show Battle Icons: Show icons of currently equipped weapons in battle?
 * This will show the icon next to the Attack command, making it easier for
 * the player to know which weapon the actor has currently equipped.
 *
 * Show Battle Action: Show animation of actor switching weapons? This is
 * for sideview only. When weapon switching is done during Attack switching,
 * the actor will perform an attack motion to display the weapon it is
 * currently equipped with.
 *
 * Extend Equip Stat Window: If you are using Yanfly's Equip Core, this will
 * extend the stat compare window to have Hit Accuracy, Evasion, and Critical.
 *
 *
 *
 * --------
 * Notetags
 * --------
 *
 * Skill and Item Notetags:
 *
 * <Switch to Weapon: x>
 * <Switch to Weapon: text>
 * When the actor uses this skill or item, the actor will switch to this
 * weapon if it is equipped when the skill cost is paid. x is the weapon
 * type ID and text is the weapon name. If you use the weapon name, type
 * it out exactly since it is case sensitive. This notetag does not make
 * the weapon a requirement. To make it a requirement, use the database's
 * "Required Weapon" dropdown lists to enforce the requirement.
 *
 *
 *
 * Skill Notetags:
 *
 * <Require Any Weapon>
 * Requires any kind of weapon to be equipped in order to use it.
 *
 * <Require Weapon Types: x>
 * <Require Weapon Types: x, x, x>
 * Insert multiple x to add more weapon types. All of the weapon types must
 * be equipped in order for this skill to be used.
 *
 *
 *
 * ---------------
 * Action Sequence
 * ---------------
 *
 * If you are using YEP Battle Engine Core, there is an action sequence that
 * lets you switch weapons for the actor in the middle of an action sequence:
 *
 * Weapon Swap: targets, x
 * or
 * Weapon Swap: targets, text
 * or
 * Swap Weapon: targets, x
 * or
 * Swap Weapon: targets, text
 *
 * Use x with the weapon type ID in the Database Type tab. Or use text and
 * replace it with the name of the weapon type. If you use the name of the
 * weapon type, type it out exactly as it is spelled because it is case
 * sensitive.
 *
