# Script: Draw Animated Characters In Windows
# Author: Evgenij
# Date: 07.01.2015
# Version: 1.0a
#
# Description: With this script you can add a new method to windows
# which will draw animated characters
#
# You need to include the EVG::AnimatedDrawCharacter Module
# into a Window class.
# Then you can use this methods:
# draw_animated_character(character_name, character_index, x, y, direction = 2)
# clear_animated_characters # clears all the characters from windows content
# # and stops drawing them
module EVG
# Adds a new method to a window when included:
# draw_animated_character(character_name, character_index, x, y, direction = 2)
module AnimatedDrawCharacter
# wait between each character frame (in frames)
WAIT_BETWEEN_FRAMES = 10
