those scripts I mad eup are by no means perfect, they were okay for converting the FOT critters, but they are just not that acurate.
I was hard to figure out just how far a critter was actaully moving each time, so I took a "best guess" at it and hope for the best.
A better way to do it is to render the person walking forward in 3d max (or what ever you are using), the scripts only need to be used if you have a criter walking on the spot, just render it so it is already moving correctly.
Compare these two animations:
The first one is just walking on the spot
The second one is walking forward
Now if you have an image you want to convert to a FRM and you only have the image walking in the spot then you will need to manualy or by a script adjust the frame offset to walk it forward, this is wha tI had to do with the FOT critters.
On the other hand if you are making your own critters dont use the frames offset to walk them forward, just render them walking forward in the correct fashion. This will make a larger FRM, but as the
very last step after converting them into a FRM use the autocutting tool in frame animator to adjust optimise the image size.
On a side note - NEVER USE THE AUTOCUTTING FEATURE IN FRAME ANIMATOR UNTIL THE VERY LAST STAGE.
If you auto cut the imagebefore running a script the image will hop up and down and look like crap, the scripts assume that the frames are all the same size but the autocutting tool adjusts the frame size, this should be the final step once you are completely finished making your critter. The autocutting tool is great for trimming the frames down in file size, but make sure it's the last thing you do.
Here's some more reason on the what autocutting before adjusting the frame offset does, in some critters it is more pronouced.
