# Version : 1.1
#
# This script is commissioned by Batworks Software.
#-------------------------------------------------------------------------------

#-------------------------------------------------------------------------------
# Version History
#-------------------------------------------------------------------------------
# 1.1 - Fixed a bug where floating enemies transforming messed up offset
# 1.0 - Initial script.
#-------------------------------------------------------------------------------

#-------------------------------------------------------------------------------
# This script provides a notetag to apply a Y offset to the position of an
# enemy's sprite:
#
# <y_offset: value>
#
# The value can be negative.
