When you swap animations, the script doesn't change, unless you change them as well. At least, you got somewhere, Madein. Also remember that bones (I think) are different for characters so try changing her bones for the sword attacks to 16 or 19. But Aeth-r, yes, you can change the animation for a different visual if you want, just know if the move has hitboxes or anything that would need a timer, it might look different than you thought.
I'm probably not going to mess with attacks very much, primarily just run/idle/jump/taunt animations.
