# Simple Cutscenes
# Author: Maximusmaxy
# Version 1.1: 8/1/12
#===============================================================================
#
# Introduction:
# This script draws a simple fade graphic to establish that a scene is
# ocurring, it also disables and scripts that may interfere with cutscenes
# such as HUD's or move speed increases.
#
# Instructions:
# To begin/end a cutscene simply type in the following call scripts:
#
# CUTSCENE.begin
# to start a cutscene
#
# CUTSCENE.end
# to end a cutscene
#
# In the configuration insert the scripts that you need disabled during
# cutscenes. This may or may not include speed boosts and hud's.
#
# For people that like eventing, you may also include switches that are
# activated/deactivated before the cutscene, this can then trigger common
# events. They will be reset to there original state at the end of the scene.
#
# Custom Images:
# You now have the option to use custom graphics for your cutscene images.
# To use this feature place the cutscene images in your pictures folder and add
# the filename of those images to the configuration. Make sure your style is
# set to 3.
#
# It is recommended to use images with a width of 640 pixels.
