# -- Level: Normal, Hard
# -- Requires: n/a

#==============================================================================
# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# 2012.01.08 - Started Script and Finished.
# 
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# For those who want an alternative for actors to learn skills outside of
# leveling, this script allows actors to learn skills through a learn skill
# menu. The actor can use acquired JP, EXP, or Gold to learn skills. Skills can
# also be hidden until certain requirements are met.
# 
#==============================================================================
# ▼ 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.
# 
# -----------------------------------------------------------------------------
# Class Notetags - These notetags go in the class notebox in the database.
# -----------------------------------------------------------------------------
# <learn skills: x>
# <learn skills: x, x>
# Sets the class to be able to learn skills x through the Learn Skills menu.
# Insert multiple of these tags to increase the number of skills learned.
# 
# -----------------------------------------------------------------------------
# Skill Notetags - These notetags go in the skill notebox in the database.
# -----------------------------------------------------------------------------
# <learn cost: x jp>
# <learn cost: x exp>
# <learn cost: x gold>
# Sets the learn for cost the skill to require x amounts of JP, x amounts of
# exp, or x amounts of gold. Only one type of cost can be used at a time. For
# JP costs, the Yanfly Engine Ace - JP Manager script must be installed.
# 
# <learn require level: x>
# Sets the skill to require the actor's current level to be x before the skill
# will show up in the skill learning window.
# 
# <learn require skill: x>
# <learn require skill: x, x>
# Sets the skill to require learning skill x (through any means) before the
# skill becomes visible in the skill learning window. Insert multiples of these
# tags to require more skills to be learned in order for the skill to show.
# 
# <learn require switch: x>
# <learn require switch: x, x>
# Sets the skill to require switch x to be ON in order for it to show in the
# skill learning window. Insert multiple switches to to increase the number of
# switches needed to be ON before the skill is shown.
# 
# <learn require eval>
#  string
#  string
# </learn require eval>
# For the more advanced users, replace string with lines of code to check for
# whether or not the skill will be shown in skill learning window. If multiple
# lines are used, they are all considered part of the same line.
# 
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
# 
# This script is compatible with Yanfly Engine Ace - JP Manager v1.00+. The
# placement of this script relative to the JP Manager script doesn't matter.
