# VARIABLE_QUESTS
# Author Molegato
# Version 1.1
#------------------------------------------------------------------------------
# Just a simple menu where some variable-based quests are shown
#------------------------------------------------------------------------------
# INSTRUCTIONS
# 
# You map each quest to a variable
# If the variable value is 0, the quest doesn't appear in the menu
# If the variable value is 1, it appears as 'unsolved'
# If the variable value is 2, it appears as 'active'
# If the variable value is 3 or greater, it appears as 'solved'
#
# Any quest on 'unsolved' state can turn into 'active' by selecting it
# on the quest menu, and only a single quest can be active at any time.
#
# To call the menu, use SceneManager.call(Scene_Quests) on a script call,
# you can directly program it on your custom menu, or put it on a common
# event attached to an item or skill, for making it easier to access.
