#==============================================================================

$imported = {} if $imported.nil?
$imported["PRX-CharacterShadow"] = true

#==============================================================================
# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# 2012.04.05 - Fixed an issue with shadow sprites not disposing properly.
# 2012.04.03 - Added Default values for Player, Followers, and Events.
# Also added some logic for hiding shadows when characters aren't
# visible.
# 2012.04.02 - First Draft Complete
#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script will allow you to add a Shadow graphic underneath the player,
# followers, and any event you feel should have a shadow graphic.
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open spot above Main.
#
# Each Game_CharacterBase and any object whose parent is Game_CharacterBase can
# have a shadow added under it's sprite by setting the shadow value to true.
#
# eg: To show the shadow graphic for the player, a Call Script such as
# $game_player.shadow = true
# will add the shadow. Conversely,
# $game_player.shadow = false
# will turn the shadow off.
#
# This will also work for Followers (the 'Caterpillar' characters) and any
# map event.
#
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made for RPG Maker VX Ace and designed to be as modular as
# possible to avoid script conflicts. It is however possible that conflicts may
# occur with other scripts that make changes/use of the Game_CharacterBase or
# Sprite_Character.

# ▼ Settings
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
#
# To use a shadow graphic other than the Shadow.png found in the System
# cache, change the following:
#==========================================================================
SHADOW_GRAPHIC = "Shadow" # The name of the Shadow file

#==========================================================================
# Change the following to have players, followers, or events use shadows
# by default
#==========================================================================
DEFAULT_ON_PLAYER = true # Set to 'true' for default shadows
DEFAULT_ON_FOLLOWER = true # Set to 'true' for default shadows
DEFAULT_ON_EVENT = false # Set to 'true' for default shadows
