Sorry to ask so many questions, but which way would you recommend cutting out each sprite from the sprite sheet for use in unity so that the animations look smooth when you put them together?
After importing the sprite sheet, you should change the Sprite mode to multiple and then click the Sprite Editor button. Here you can slice the sprite with type "Grid by cell size". Type in cell width 100 and height 55. You can check out the preview files in order to get a grasp of where each animation begins and ends in the sprite sheet. Hope that helped!
