title: How to create wind effect in spritekit
body: <p>I was playing angry birds and arrived at this stage where the wind "blows" you and kinda pushes you. was kinda interesting but I really couldnt figure the logic or code that would accomplish this.
  I know that you could probably use the emitter to create the wind like "look" 
  but i would really like some insight on how you would accomplish the "pushing" of the sprite.</p>
  
  <p>Thank you</p>
