title: SpriteKit - How can I catch the event when the touch moves over a sprite, but didn't actually begin on the sprite
body: <p>In SpriteKit, I want to catch event when touch moves over a sprite, but hasn't actually started on this sprite, but on another piece of SKScene. </p>
  
  <p>I can catch touchesBegan inside the SKSpriteNode A if the touch starts on it and then dragged over it, but not when touch started on another node - B - and then dragged over my node - A. Anyone knows how to catch this one, because I think I am doing something wrong here.</p>
