# HEIRUKICHI SCROLL TEXT CONFIG
#===========================================================================
# - Version 1.1
# Last update: 07-02-2018 [M-D-Y]
#===========================================================================
# TERMS OF USE
#---------------------------------------------------------------------------
# You are free to use this script for both commercial and non commercial
# games as long as you give proper credit to me (Heirukichi).
# I would like to be notified in case you decide to use this script for
# commercial purposes and it would be nice if you could provide me a link to
# the selling page (not a free copy of your game, just a link to its page).
# It would be very appreciated if you could do the same for non-commercial
# games too but that is not mandatory.
#===========================================================================
# DESCRIPTION
#---------------------------------------------------------------------------
# This script allows you to set a new starting coordinates and size for
# Window_ScrollText. This way you can display a scrolling text in just a
# portion of your game screen.
#===========================================================================
# INSTRUCTIONS
#---------------------------------------------------------------------------
# The script is plug and play, just copy/paste it in your materials and it
# is ready to work. No configuration needed.
#
# Window_ScrollText will be untouched until you actually want to resize it.
# When that happens you can use a script call and write
#
#   set_scroll_text_size(new_x, new_y, new_width, new_height)
#
# You have to pass all these parameters even if you want a few of them to be
# the same as the default ones. For that reason you I decided to add the
# default value for each parameter after their description below.
#
# new_x is your new starting x position (default value is 0).
# new_y is your new starting y position (default value is 0).
# new_width is your new window width (default is Graphics.width)
# new_height is your new window height (default is Graphics.height)
#
# Since window width and height cannot be 0 if you set those values to 0
# that change will have no effect at all and the default value is applied
# instead.
#
# After using that in a script call you can just use your Show Scroll Text
# event command as usual.
#===========================================================================
# COMPATIBILITY
#---------------------------------------------------------------------------
# In order to prevent compatibility issues with scripts that overwrite the
# aliased methods place them ABOVE this one.
#---------------------------------------------------------------------------
# METHODS
#---------------------------------------------------------------------------
# Window_ScrollText
#   * resize (new method)
#
# Game_Interpreter
#   * command_105 (aliased method)
#   * resize_scroll_text_window (new method)
#   * set_scroll_text_size (new method)
#===========================================================================
# UPDATES
#---------------------------------------------------------------------------
# Update 1.1
#   - New resize method for Window_ScrollText instead of the overwritten
#     initialize method (Thanks to TheoAllen for pointing this out).
#   - Improved performance when resizing window size.
