title: Swift SpriteKit - Sprite vs Other Graphics
body: <p>Is there a different graphics file format like a vector / 3d graphics model that is used in 2D games for ease of rotation?</p>
  
  <p>In the past, I would use a set of sprites that have 8 direction animation for character walking.  Is there a better way to animate a character walking using 1 character file format?  Not sure if I am asking the right question.</p>
  
  <p>I figured that a 3D model can be rotated to the direction the character is walking to reduce the need for additional sprites.</p>
  
  <p>What do games like RPG, Evony use for sprite animation? </p>
