Popup Window

#Popup Window v1.2d
#----------#
#Features: Create a popup window for anything you want! How magical!
#
#Usage:    Script calls:
#           (In Events:)
#           pop_up(['text','text', ... ], timer(opt), x(opt), y(opt))
#           (Anywhere else:)
#           Popup.add(['text','text', ... ], timer(opt), x(opt), y(opt))
#
#          Examples:
#           pop_up(['\i[5] Mage class unlocked!!'])
#           pop_up(['\c[16] Class Change:\c[0]',
#                   ' Speak to any mysterious hermit to change class!'],240)
#
#   Escape codes not working? You have two options... switch to '' singe quotes
#    instead of "" double quotes, or double up on \\ slashes.
