# Informational Long Text Scene
# by jfjohnny5
# 11/21/2010
#==============================================================================
# Creates a new scene for displaying long text fields to be used as tutorials,
# background story, or other informational material.
#
# The key to the "Long Text Window" is that the text content is loaded from
# external text files and can be of almost any length, as the script
# dynamically creates as many pages as are needed to display the content.
#
# Edit the COMMANDS list below to include the name for the given entry as well
# as the relative path to the .txt file containing the long text.
#
# You must include the following image file for the "more text" indicator:
#
# <project folder>\Graphics\Pictures\more_text.png
#
#------------------------------------------------------------------------------
# use the following script call to create the scene:
#
# $scene = Scene_Tutorial.new
#
#==============================================================================
$imported = {} if $imported == nil
$imported["TutorialScene"] = true

# CONFIGURATION

  # Customize menu options and associated text files here. Be sure that any
  # additional selections follow the numbering convention (0,1,2,3,4,5,etc).
  # Text file path is relative to the main directory for the RPGM project.
  # The default configuration points to files in a "Text" subdirectory.
