Just remember all of your attack animations will have to be original, what I mean is you can't copy the SW attack for the SE attack, because the guns on the battleship are always turned to the right, with relation to which direction the bow is facing, believe me, I know. What I did on all 3 of my battleships that I made was keep the original battleship file open, and keep the one I was working on open, cut the images down so that I had each one right next to the other, then just cut and paste from one image to another whichever part I needed. For instance, the run animation, just copy the water ripples, and paste them in place on your ship. Be especially careful, and this goes with any unit, that you pay attention to the original Firaxis units. Because some of their pcx files will be bigger and smaller than others, some of the frames will be different sizes. Don't simply copy a frame from your default, and then paste it in your run file, if you do, the ship may jump from flc. to flc. in game, which can be very frustrating when you playtest it and are looking forward to bombarding bararians in 4000 bc. The solution is just to copy the battleship itself, no background, then paste it in a new pcx file, as closely ontop of the batteship in that file as you can.
