#
|
|
||||||
# A script to pack individual animation sequence frames for a set of
|
|
||||||
# components into a single large image for each action sequence for
|
|
||||||
# each component. The resulting images are added to a zip archive to
|
|
||||||
# facilitate transmission from one place to another.
|
|
||||||
#
|
|
||||||
# The animation frames are expected to be stored one per file, and
|
|
||||||
# represent each component viewed in each of the 8 cardinal compass
|
|
||||||
# directions (N, NE, E, SE, S, SW, W, NW) for each action sequence.
|
|
||||||
# Current action sequences are "standing" and "walking".
|
|
||||||
#
|
|
||||||
# For now, animation frame image file names are required to conform to
|
|
||||||
# the following format:
|
|
||||||
#
|
|
||||||
# M_<component abbreviation>_Cam0[1-8]_000<0-6>.png
|
|
||||||
# ^ ^
|
|
||||||
# | |
|
|
||||||
# orientation frame
|
|
||||||
# index
|
|
||||||
#
|
|
||||||
# The standing action sequence has only 1 frame of animation for each
|
|
||||||
# orientation. The image is expected to be in the file for frame
|
|
||||||
# index 0.
|
|
||||||
#
|
|
||||||
# The walking action sequence has 6 frames of animation for each
|
|
||||||
# orientation. The images are expected to start at frame index 1,
|
|
||||||
# with other frames following.
|
|
||||||
#
|
|
||||||
# Accordingly, there should be a total of 56 image files for each
|
|
||||||
# component (8 frames for standing, and 48 frames for walking.)
