title: Special Kind of ScrollView
body: <p>So I have my game, made with SpriteKit and Obj-C. I want to know a couple things.</p>
  
  <p><strong>1) What is the best way to make scroll-views in SpriteKit?</strong></p>
  
  <p><strong>2) How do I get this special kind of scroll-view to work?</strong></p>
  
  <p>The kind of scroll-view I'd like to use is one that, without prior knowledge, seems like it could be pretty complicated. You're scrolling through the objects in it, and when they get close to the center of the screen, they get larger. When they're being scrolled away from the center of the screen, they get smaller and smaller until, when their limit is met, they stop minimizing. That limitation goes for getting bigger when getting closer to the center of the screen, too.</p>
  
  <p>Also, I should probably note that I have tried a few different solutions for cheap remakes of scroll views, like merely adding the objects to a SKNode and moving the SKNode's position relative to the finger's, and its movement . . . but that is not what I want. Now, if there is no real way to add a scroll-view to my game, this is what I'm asking. Will I simply have to do some sort of formula? Make the images bigger when they get closer to a certain spot, and maybe run that formula each time <code>-touchesMoved</code> is called? If so, what sort of formula would that be? Some complicated Math equation subtracting the node's position from the center of the screen, and sizing it accordingly? Something like that? If that's the case, will you please give me some smart Math formula to do that, and give it to me in code (possibly a full-out <em>function</em>) format?</p>
  
  <p>If <strong>ALL</strong> else fails, and there is no good way to do this, what would some other way be?</p>
