I plan on making more saber styles, but I'm limited by the lack of sp code.
1. I can't add styles to the game, I can only overwrite them. I can kind of get around this by applying animations specifically to a model like what I've done for the SA and Link. That let's me make a style that only that person would use at the expense of another style. No staff for SA and no duals for Link.
2. I can't change the transitions between attacks. Think of how much the player spins while using 2 sabers. I can't remove the fact he has to spin for those. I can animate them as non-spins (called 'arcs') but the lower legs will not behave like they do in the arcs. I have a plan to make a really cool Makashi style, but since I can't change transitions from spins to arcs, it's not going to work.
I can make as many models we want have specific animations. Evey time I do though it adds at least 13 mb to the mod. 3 or so for the model, and 10 for the animations.
