Pasp's Glitch Effects v1.0

#===============================================================================
# Pasp's Glitch Effects v1.0
#-------------------------------------------------------------------------------
# Can be used to create a "glitching" effect over the current screen, with
# the option to add a sound effect as well.
#-------------------------------------------------------------------------------
# Instructions:
# Place script below Materials and above Main
#
# Use the script call "show_glitch" when you want to have a glitching effect
# "show_glitch" can be used with the defaults, or with the arguments intensity,
# duration, volume, and pitch in that order.
#
# For example: show_glitch(10,20,100,50)
# This will create a glitch effect with a maximum pixel shift of 10 pixels that
# lasts for 20 frames, with a sound effect volume of 100 and sound effect pitch
# of 50.
# Default values are intensity = 5, duration = 3, volume = 100, and pitch = 100
#-------------------------------------------------------------------------------
# History:
# June 10, 2026: v1.0 release
#-------------------------------------------------------------------------------
# Terms:
# Can be used in free and commercial games or modified however you like, but
# please credit!
