# 2012.08.06 - Restore SP-Paramater: TCR
# 2012.01.23 - Compatibility Update: Doppelganger
# 2011.12.11 - Started Script and Finished.
#            - Added max and min notetags.

#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script adds more functionality towards skill costs. Skills can now cost
# HP, more MP, more TP, gold, and even have custom costs. The way the skill
# costs are drawn in the display windows are changed to deliver more effective
# and reliable information to the player. And if four skill costs aren't enough
# to satisfy you, you can even make your own custom skill costs.
#

# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
# 
# -----------------------------------------------------------------------------
# Actor Notetags - These notetags go in the actors notebox in the database.
# -----------------------------------------------------------------------------
# <hp cost rate: x%>
# Allows the actor to drop the HP cost of skills to x%.
# 
# <tp cost rate: x%>
# Allows the actor to drop the TP cost of skills to x%.
# 
# <gold cost rate: x%>
# Allows the actor to drop the Gold cost of skills to x%.
# 
# -----------------------------------------------------------------------------
# Class Notetags - These notetags go in the class notebox in the database.
# -----------------------------------------------------------------------------
# <hp cost rate: x%>
# Allows the class to drop the HP cost of skills to x%.
# 
# <tp cost rate: x%>
# Allows the class to drop the TP cost of skills to x%.
# 
# <gold cost rate: x%>
# Allows the class to drop the Gold cost of skills to x%.
# 
# -----------------------------------------------------------------------------
# Skill Notetags - These notetags go in the skills notebox in the database.
# -----------------------------------------------------------------------------
# <hp cost: x>
# Sets the skill's HP cost to x. This function did not exist by default in
# RPG Maker VX Ace.
# 
# <hp cost: x%>
# Sets the HP cost to a percentage of the actor's MaxHP. If a normal HP cost is
# present on the skill, too, then this value is added to the HP cost.
# 
# <hp cost max: x>
# <hp cost min: x>
# Sets the maximum and minimum range of the HP Cost of the skill. If you do not
# use this tag, there will be no maximum and/or minimum range.
# 
# <mp cost: x>
# Sets the skill's MP cost to x. Allows MP cost to exceed 9999, which is RPG
# Maker VX Ace's database editor's maximum limit.
# 
# <mp cost: x%>
# Sets the MP cost to a percentage of the actor's MaxMP. If a normal MP cost is
# present on the skill, too, then this value is added to the MP cost.
# 
# <mp cost max: x>
# <mp cost min: x>
# Sets the maximum and minimum range of the MP Cost of the skill. If you do not
# use this tag, there will be no maximum and/or minimum range.
# 
# <tp cost: x>
# Sets the skill's TP cost to x. Allows TP cost to exceed 100, which is RPG
# Maker VX Ace's database editor's maximum limit.
# 
# <tp cost: x%>
# Sets the TP cost to a percentage of the actor's MaxTP. If a normal TP cost is
# present on the skill, too, then this value is added to the TP cost.
# 
# <tp cost max: x>
# <tp cost min: x>
# Sets the maximum and minimum range of the TP Cost of the skill. If you do not
# use this tag, there will be no maximum and/or minimum range.
# 
# <gold cost: x>
# Sets the skill's gold cost to x. Enemies with skills that cost gold do not
# use gold. If the player does not have enough gold, the skill can't be used.
# 
# <gold cost: x%>
# Sets the skill's gold cost equal to a percentage of the party's total gold.
# If both a regular gold cost and a percentile gold cost is used, the total of
# both values will be the skill's gold cost.
# 
# <gold cost max: x>
# <gold cost min: x>
# Sets the maximum and minimum range of the Gold Cost of the skill. If you do
# not use this tag, there will be no maximum and/or minimum range.
# 
# --- Making Your Own Custom Costs ---
# 
# <custom cost: string>
# If you decide to have a custom cost for your game, insert this notetag to
# change what displays in the skill menu visually.
# 
# <custom cost colour: x>
# This is the "Window" skin text colour used for the custom cost. By default,
# it is text colour 0, which is the white colour.
# 
# <custom cost size: x>
# This is the text font size used for the custom cost in the display windows.
# By default, it is font size 20.
# 
# <custom cost icon: x>
# If you wish to use an icon for your custom cost, replace x with the icon ID
# you wish to show in display windows. By default, it is 0 (and not shown).
# 
# <custom cost requirement>
#  string
#  string
# </custom cost requirement>
# Sets the custom cost requirement of the skill with an eval function using the
# strings in between. The strings are a part of one line even if in the notebox
# they are on separate lines.
# 
# <custom cost perform>
#  string
#  string
# </custom cost perform>
# Sets how the custom cost payment is done with an eval function using the
# strings in between. The strings are a part of one line even if in the notebox
# they are on separate lines.
# 
# -----------------------------------------------------------------------------
# Weapon Notetags - These notetags go in the weapons notebox in the database.
# -----------------------------------------------------------------------------
# <hp cost rate: x%>
# Allows the weapon to drop the HP cost of skills to x% when worn.
# 
# <tp cost rate: x%>
# Allows the weapon to drop the TP cost of skills to x% when worn.
# 
# <gold cost rate: x%>
# Allows the weapon to drop the Gold cost of skills to x% when worn.
# 
# -----------------------------------------------------------------------------
# Armour Notetags - These notetags go in the armours notebox in the database.
# -----------------------------------------------------------------------------
# <hp cost rate: x%>
# Allows the armour to drop the HP cost of skills to x% when worn.
# 
# <tp cost rate: x%>
# Allows the armour to drop the TP cost of skills to x% when worn.
# 
# <gold cost rate: x%>
# Allows the armour to drop the TP cost of skills to x% when worn.
# 
# -----------------------------------------------------------------------------
# Enemy Notetags - These notetags go in the enemies notebox in the database.
# -----------------------------------------------------------------------------
# <hp cost rate: x%>
# Allows the enemy to drop the HP cost of skills to x%.
# 
# <tp cost rate: x%>
# Allows the enemy to drop the TP cost of skills to x%.
# 
# -----------------------------------------------------------------------------
# State Notetags - These notetags go in the states notebox in the database.
# -----------------------------------------------------------------------------
# <hp cost rate: x%>
# Allows the state to drop the HP cost of skills to x% when afflicted.
# 
# <tp cost rate: x%>
# Allows the state to drop the TP cost of skills to x% when afflicted.
# 
# <gold cost rate: x%>
# Allows the state to drop the Gold cost of skills to x% when afflicted.
