# * Setup 
# -~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-
# To install this script, copy and paste it under the materials section and
# above main. This script requires the following bit of code to work:
#
# ($imported||={})["Numeric Form Regex"] = true
#
# module NumericForm
#  Regex = /\A(?:-|)\d+(?:\.|)(?:\d+|)\Z/
# end
#
# This is because I don't want to include it in every script I write that needs
# it so just copy and paste that module and the imported hash into a 
# section above everything else or into a separate slot in the editor.
#
# You will also need to get the other dependencies listed in the header. You
# can find them at: http://rascripts.wordpress.com/2012/11/07/upgradable-equipment/

# Specifying Equipment as Upgradable:
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 
# Use the notetag:
#
# <upgradable>
#
# to mark a piece of armor or a weapon as upgradable.
# You can also specify how many times the equipment can be upgraded, for example:
#
# <upgradabe 2>
#
# means the equipment can be upgraded twice.

# Making an Upgrader
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 
# Upgraders are items that can be used to modify the stats of equipment that is
# upgradable.
# 
# Use any of the following notetags to do this, the first INTEGER should 
# correspond to the stat you want to modify, the second should be the value that
# it will be modified by.
# 
# These are the default stats and their associated INTEGERs:
# 
# Max HP: 0 
# Max MP: 1 
# Attack Power: 2 
# Defense: 3 
# Magic Power: 4 
# Magic Defense: 5 
# Agility: 6 
# Luck: 7
#
# Notetags:
#
# <upg stat INTEGER +INTEGER> 
# <upg stat INTEGER +INTEGER%>
# <upg stat all +INTEGER%>
# <upg state INTEGER INTEGER%>
#
# ** The '+' signs can be replaced with '-' signs, don't forget the '%' signs 
#    where they are required **
#
# The first on the list:
#
# <upg stat INTEGER +INTEGER> 
#
# will allow you to modify the stat corresponding to the first integer by the 
# value of the second integer.
# For example:
#
# <upg stat 5 +143>
#
# Means the upgrader will increase the magic defense stat of the upgraded item
# by 5.
#
# The second note tag:
#
# <upg stat INTEGER +INTEGER%>
#
# Allows a specific stat to be modified by the specified percentage:
#
# <upg stat 0 +10%>
#
# Will increase the HP stat by 10 percent.
#
# The third notetag:
# 
# <upg stat all +INTEGER%>
#
# Will modify all stats by the specified percent:
# 
# <upg stat all -5%>
# 
# will cause all stats to be decreased by 5 percent on the upgraded equipment.
#
# The Fourth notetag:
#
# <upg state INTEGER INTEGER%>
#
# Will cause the upgraded equipment to have a chance of inflicting the state
# with an id equal to the first INTEGER, 'the second INTEGER' pecent of the time:
#
# <upg state 0 10%>
#
# Will cause the upgraded equipment to have a 10 percent chance to inflict the 
# death state.
# Note, the number specified as the first INTEGER is simply the id of the state
# as it is listed in the database.

# Restricting Upgrader Usage
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 
# 
# You can restrict which upgraders can be used on which equipment by giving the
# upgraders and the upgradable equipment types.
# If an upgrader has a type, it can only upgrade upgradable equipment that 
# shares a type with it.
# More than one type can be specified per upgrader and/or upgradable equipment 
# piece.
#
# When sepcifying the upgrader type for an upgrader, use the notetag:
# 
# <upgrader ANYTHING>
#
# ** ANYTHING should be the string representing the upgraders type **
# For example:
# 
# <upgrader shield>
# 
# would specify an upgrader that could only be used on upgradable equipment that
# had a shield type spcified.
#
# When specifying the upgradable type for a piece of upgradable equipment, use
# the notetag:
#
# <upgraded by ANYTHING>
#
#** ANYTHING should be the string representing the upg equip type **
# For example:
#
# <upgraded by shield>
#
# would mean that the equipment item could only upgraded by upgraders that were
# marked with the <upgrader shield> notetag.

# Calling the Script 
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#
# The Upgrade Window can be called from an event with this script call:
#
# ra_upg
#
# If you want to restrict which upgraders can be used during the upgrading scene
# use the script call:
#
# ra_upg(ARRAY)
#
# replace 'ARRAY' with an array of strings of the specific upgrader types that 
# you want to use during that scene.
#
# For example if you have 2 items in your database, one is marked with the notetag
# <upgrader shield> and the other one is marked with the notetag 
# <upgrader defensive>
# and you only wanted to be able to use the "shield" upgraders during the upgrade
# scene, you would use the script call:
#
# ra_upg(["Shield"])
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
# Equipment Suffixes
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
# 
# Upgraders can be specified to add sufixes to the names of the equipments they
# are upgrading.
# Use the notetag:
#
# <upg suffix ANYTHING>
#
# ** 'ANYTHING' should be replaced with the string you want to use as a suffix.
# To mark the upgrader with a suffix to add onto the equipment it upgrades.
# For example, if an upgrader was marked with the notetag:
#
# <upg suffix +20 Dec>
#
# if it was then used on an upgradable shield named, "Wooded Shield", the
# shield's name would be changed to "Wooden Shield +20" after it was upgraded.
#
# There are several constants that can also be set to modify how many suffixes
# are displayed on a piece of equipment, etc.:
#
# Set Only_Show_Most_Recent_Suffix to true if you only want to show 1 suffix
# on the equipment.
#
# Set Show_Upgrade_Quantity_In_Name to true if you want to display how many 
# times the equipment was upgraded in the name.
#
# Change the maximum amount of suffixes that can be displayed in an items name
# with Max_Suffixes

# Failure Rate
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#
# The chance that an upgrade will be successful can be modified in 
# EquipUpgrades::Player::DefaultFailRate below. Or it can be modified during
# runtime by accessing $game_player.fail_rate_for_upgrades
#
# By default, increasing the value by 1 increases the failure rate by 1%, this
# will change though if EquipUpgrades::Max::BaseRVal is modified. 
# The failure rate at the start of a new game will be equal to 
# EquipUpgrades::Player::DefaultFailRate/ EquipUpgrades::Max::BaseRVal

# Update Log:
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#  14 Dec 2012 - Neatened up the documentation.
#  13 Dec 2012 - Major Bug Fixes: 
#
#                Can now add suffixes to upgraders to be shown on the upgraded
#                equipment.
#                Equipment no longer disappears when you save a game while
#                wearing upgraded equipment.
#
#                Database is now properly managed (tmk) during runtime but custom
#                items are no longer deleted from the database because of the 
#                difficulty associated with ensuring an items id is the same
#                as its location in the database when removing and readding items.
#
#                Known Bug, Not fixing yet:
#
#                If you have a saved game with upgraded equipment and you add a
#                new item to the database in the editor, then load that saved 
#                game, some of the custom equipment may appear to "disappear"
#                or you may have different items in your inventory.
#
#  12 Dec 2012 - Can now use any symbol when specfying upgraders, not just A-Z
#                slight changes to note tags, can replace 'mod' with 'upg'
#  10 Dec 2012 - Fixed Freeze during ugrade scene.
#  9 Dec 2012  - Added support to restrict which upgraders can be used during the
#                upgrade scene. Use the script call:
#                ra_upg(ARRAY) 
#                ** replace "ARRAY" with an array of strings **
#                to only allow upgrader with a type specified in the array to be
#                used.
#  20 Sept 2012 - Upgraders can now be specified to only be used with a specific
#                 Equipment (use the tags <Upgrader "A"> and <Upgraded By "A">)
#  19 Sept 2012 - Fixed a problem where armor wasn't being upgraded properly.
#                 Was referencing $data_weapons inside deep_copy_clone_2544 of
#                 RPG::Armor, meant to reference $data_armors
#  4 Sept 2012  - UpgradeOrientation::Size::WidthValue can now be used to adjust
#                 the width of the windows in the upgrade scene
#  3 Sept 2012  - Misnamed method update_data_base_upg_equips inside RPG::Armor, 
#                 was corrected.
#  29 Aug 2012  - The name of the item has been changed to display how many 
#                 upgrades have been used on it.
#               - Upgraded equipment is now removed from the database also when it
#                 is being removed the party's inventory
#               - Text now fits correctly in the equipment selection options window
#
#  28 Aug 2012  - Added notetag support to limit the amount of upgrades that can 
#                 be used on an item. <!upgradable9> limits the item to no more 
#                 than nine upgrades.
#               - Added a nil check to fix a crash that was happening when 
#                 selecting a blank item.
#               - Fixed a NameError. Updated a module constant name I had 
#                 forgotten to change after moving the constant to a new module.
#               - Fixed overlapping text inside the item list window
