#           N.A.S.T.Y. Replace Window with Picture
#               Nelderson's Awesome Scripts To You
# By: Nelderson
# Made On: 3/11/2015
# Last Updated: 3/12/2015
#===============================================================================
# Update History:
# - Version 0.5 - Initial Release - Technically BETA/Tesing Stage
# - Version 1.0 - Fixed issues with the Message window and added
#                 feature to change picture to a window with a script call
#===============================================================================
# *Notes:
#  -This script uses pictures instead of windows you specify.
#===============================================================================

#===============================================================================
#  Instructions:
#
#  -Configure the PICWINDOW Hash below. It should work with not only 
#   default windows, but custom windows from other scripts as well.
#
#  -If you want to know how big your window is to make a picture,
#   the best way is to look at the initialize method on each window
#   class.  It is usually in the format (x, y, width, height).
#   So the picture you need to make should be the same width and height.
#
#  -You can change the pic of the window you want by using the script call:
#     change_nelwinpic(window, "pic") 
#        Where window is the class and pic is the name in the pictures folder.
#        Ex. change_nelwinpic(Window_Gold, "Gold")
#===============================================================================
# Take the Window Class name => Name of the "picture" in the Pictures folder 
# Example:
# Window_Gold => "Gold",

module NEL    
  PICWINDOW ={   # <=== Do Not Remove      
    Window_Message => "BlueMessage",  
    Window_Gold => "BlueGold",  
    Window_MenuStatus => "BlueStatus",  
    Window_MenuCommand => "BlueCommand",  
    Window_NameInput => "pic4",  
    Window_NameEdit => "blah",
  } # <=== Do Not Remove
end

#==============================================================================
#
#                            END OF CUSTOMIZATION
