Actor Battle Items

[Mel]

Okay, I added some stuff to the script

- Minor usability improvements
- A stack limit for each item in the actor inventories
- An item limit for the actor inventories

Feel free to test it out I don't guarantee anything^^

# ** Actor Battle Items
#------------------------------------------------------------------------------
#    by DerVVulfman
#    version 1.1
#    11-02-2020 (mm/dd/yyyy)
#    RGSS / RPGMaker XP
#==============================================================================
#
#  USAGE:
#
#  Ever wondered  how your entire party can grab potions from the same grab-
#  bag of items unhindered?  Did you think that certain heroes may or should
#  have items that another cannot?  If so, this script may be for you.
#
#  This script forces the game player to actively prepare his party for com-
#  bat,  demanding that the player distribute items usable in combat between
#  each party member. Actors not equipped with their own personal items will
#  not be able to use an 'every party member' grab bag of items as before.
#
#  This system  adds a pop-up window  which asks  if a chosen item  is to be
#  used or transferred  to an individual party member.   This window appears
#  in the Item menu  and the  new Battle Items menu  which appears  for each
#  individual actor.   Transferring items between current actors is not only
#  possible, but is an option available in-battle if so configured.
#
#------------------------------------------------------------------------------
#
#  USAGE:
#
#  Based uppn the default scripts package that comes with RPGMaker XP,  this
#  system affects the Item Menu and battlesystem's item select options,  and
#  adds a new Battle Items menu for lack of a better title.
#  
#  While within  the item menu,  you will receive a pop-up display  when you
#  select an item  that may be used within battle.  This pop-up display asks
#  whether you wish to immediately use the item, or if wish to take the item
#  from the collective item list and give it to one of the party members.
#
#  And while in battle,  choosing the  Item option  from the Actor's Command
#  Window will bring up only those items that were specifically given to the
#  actor currently highlighted.  You will not be able  to use items from the
#  party's collective bag of items.
#
#  Meanwhile, a new menu was created,  the Battle Items menu  which is meant
#  to be added or used  within the game's main menu.   The Battle Items menu
#  acts much like the Item Menu in that selecting an item brings up a pop-up
#  display asking the player  if immediate use o r transfer to another actor
#  is desired.   Only combat items can be listed as only combat items can be
#  placed here by the Item Menu.
#
#  The system has some options available.   One option  is to enable/disable
#  the ability to move an item from the Battle Items menu back to the normal
#  item menu.  The other is to enable/disable the ability  to transfer items
#  between actors during combat, or if they are just immediately used.
#
#------------------------------------------------------------------------------
#
#  CONFIGURATION:
#
#  The system has some options available.   One option  is to enable/disable
#  All configuration variables are stored within the BattleItems module, and
#  should be self explanatory.   One set adjusts the placement of the pop-up
#  display, the second set handles the actual text in the window  (something
#  I like to do  for non-English users),  and the last  two variables handle
#  the enable/disable features I discussed earlier.
#
#------------------------------------------------------------------------------
#
#  CONFLICTS:
#
#  This was designed with the default RPGMaker XP script set system in mind,
#  and did change much within Scene_Item and the Scene_Battle.
#
#  Within the  Scene_Item class,  new code was added  to the main and update
#  methods and the update_item was completely rewritten.
#
#  Within Scene_Battle,  the main, update and update_phase3 methods received
#  new code.  But the start_item_select, update_phase3_item_select,  and the
#  make_item_action_result were altered.
#
#------------------------------------------------------------------------------
#
#  SCRIPT CALLS:
#
#  Within Scene_Battle,  the main, update and update_phase3 methods received
#  While making this,  it made sense to ensure that some things  can work by
#  way out outside commands. You may wish to add an item specifically to the
#  items carried by a certain actor or see the list of items an actor may be
#  carrying at the time.  These are not high-detailed script calls,  but are
#  instead pretty rudimentary.
#
#  Executing / Running the Battle Items scene...
#  $scene = Scene_BItem.new(@status_window.index)
#  This is what you normally  would have placed within the Main Menu.  The
#  @status_window.index identifies the actor within the game party that is
#  being shown.
#
#  Checking an actor's Inventory:
#  p $game_party.actors[0].items
#  This just prints the array of items for the lead party actor as you would
#  expect.
#
#  Adding an item to an actor's personal inventory:
#  $game_party.actors[2].gain_item(2, 3)
#  This adds three 'High Potions' (Item #2 in the database) to the 3rd actor
#  of your party.
#
#  Other commands should be possible as the add and remove items placed into
#  the Game_Actor class mimick those within the Game_Party class.
#
#
#------------------------------------------------------------------------------
#
#  MORE STUFF?:
#
#  Other commands should be possible as the add and remove items placed into
#  Nope.  This is as far as I go with this script. Yep, I heard all sorts of
#  ideas, making individual weights for each item for encumbrance,  limiting
#  the number of items that can be carried, eliminating the Item Menu itself
#  and making the player choose who gets what immediately after battle.
#
#  All of these  would make  the script more extensive,  and I am ending the
#  production right here.  Other users can work out their own additions.
#
#------------------------------------------------------------------------------
#
#  TERMS AND CONDITIONS:
#
#  Free to use, even in commercial projects.  Just note that I need some form
#  of due credit... even a mere mention in some end titles.
