# ** Dynamic Shadows
#------------------------------------------------------------------------------
# Rataime
# Version 4.0
# 06/05/2007 (2007-05-06)
# Version 1.0 was based on Genzai Kawakami's shadows, extra features Boushy
#==============================================================================
#==============================================================================
# Here's the brand new free configuration feature
# The comments will be compared to the pattern using Regexp, except that I did
# the entire work for you, so you don't have to know regexps at all.
# Just choose the trigger ('s', 'begin shadow' or whatever), and the pattern
# The pattern can be one line or a list to use multiple comment lines.
# arg1 is the minimum angle
# arg2 is the maximum angle
# arg3 is the maximum distance
# The only thing you must do is using 'trigger' before the arguments
# Examples :
#
# SHADOWS_SOURCE_COMMENT_TRIGGER = 's'
# SHADOWS_SOURCE_COMMENT_PATTERN = ['trigger','arg1','arg2','arg3']
# SHADOWS_CHAR_COMMENT_TRIGGER = 'o'
# SHADOWS_CHAR_COMMENT_PATTERN = 'trigger'
# is the old way to use shadows, with a single 's' in the first line, and the
# arguments in following lines
#
# SHADOWS_SOURCE_COMMENT_TRIGGER = 'begin shadow source'
# SHADOWS_SOURCE_COMMENT_PATTERN =
# ['trigger','anglemin arg1','anglemax arg2','distancemax arg3']
# SHADOWS_CHAR_COMMENT_TRIGGER = 'begin shadow'
# SHADOWS_CHAR_COMMENT_PATTERN = 'trigger'
# will work with :
# Comment "begin shadow source"
# Comment "anglemin 0"
# Comment "anglemax 0"
# Comment "distancemax 250"
#
# Take the time to choose something you like, and something compatible with other
# scripts.
# Note that the comments will be detected even if they aren't in the beginning
# of the event's action list. Ah, and you can switch the arguments if you like
#==============================================================================
#==============================================================================
# Here is the method I like best, because of its compatibility with other
# scripts. But don't hesitate to change it.
# It will react to something like Shadow|0|0|250
#==============================================================================
SHADOWS_SOURCE_COMMENT_TRIGGER = 'Shadow'
SHADOWS_SOURCE_COMMENT_PATTERN = 'trigger|arg1|arg2|arg3'
SHADOWS_CHAR_COMMENT_TRIGGER = 'o'
SHADOWS_CHAR_COMMENT_PATTERN = 'trigger'
#==============================================================================
# An important option : if you set it to true, the shadows will get longer if
# you are far from the source. Nice, but induces lag : it will eat your CPU,
# and quite possibly your first born if you try that on a big map.
#==============================================================================
SHADOW_GETS_LONGER = true
#==============================================================================
# Misc options
# If an event has its opacity below SHADOWS_OPACITY_THRESHOLD, no shadow will
# be displayed.
# Set SHADOWS_CATERPILLAR_COMPATIBLE to true if you uses the caterpillar script
#==============================================================================
SHADOWS_OPACITY_THRESHOLD = 254
SHADOWS_CATERPILLAR_COMPATIBLE = true
#==============================================================================
# You probably won't need to touch this : it's the 'map' of how to display the
# shadow depending on the event's direction and his relative position to the
# source. a minus means the shadow is mirrored. It seems complex, and it is.
# Complain to Enterbrain (why didn't they use something clockwise or counter-
# clockwise ? I suspect it's because of the rm2k legacy. More explanations
# below.
