title: as3 rotational drag / acceleration
body: <p>Sprite.rotation+=10;
  Sprite.rotation*=0.97;</p>
  
  <p>because in as3 the system goes from 180 to -180 I don't know how to apply a drag to a constantly rotating object if it moves either direction. Do I have to convert to radians somehow and then do something? I am pretty bad with math.</p>
