# Skill Shop
# Author: Game_guy
# Date: June 7th, 2009
# Version: 1.8
#===============================================================================
#
# Intro:
# What this script does is act as a shop but sells skills instead.
#
# Instructions:
# 1: First how do you want it setup? Theres two ways
#    1: -Any person can learn any skill
#    or
#    2: -Classes learn different skills then other classes
#
#    Go down to UseClasses and set it to false for 1: or true for 2:
 
# 2: Ok now that thats over lets move onto price. Go down to CONFIG PRICE and follow
#    the instructions there.
#  
# 3: Skip this step if you set UseClasses to false.
#    Go to CONFIG CLASS SKILLS and follow the instructions there.
#   
# 4: Ok so everythings setup now. Time to actually find out how to open the
#    skillshop right? You use this line
#    $scene = SkillShop.new([skill id's go here])
#    example
#    $scene = SkillShop.new([1, 2]) will make a shop with the skills
#    Heal and Great Heal
#
# 5: Ok the script now is able to make it where only skills are learnable at
#    certain levels. Go to CONFIG LEVEL and follow instructions there.

<기본 사용법>
이벤트 편집창에서 '스크립트'를 추가 하시고 다음 스크린샷과 같이 입력합니다.

Tip. 전체 스킬을 목록에 나타나게 하시려면 다음과 같이 입력합니다.
skills = (1...$data_skills.size).to_a
$scene = SkillShop.new(skills)

<가격 수정/추가 방법>
스크립트 에디터에서 스킬샵 스크립트를 여시고 아래 지시대로 수정/추가 합니다.
