title: SpriteKit Racing top down Game
body: <p>I want to write a simple top down racing game for iOS. I want to use Sprite Kit instead Cocos2D , I'm new to game development and I have a question: </p>
  
  <p>How can I create the race tracks? What I think is: One single big background image for each track and a car that moves over it and remains inside the track by interaction with a path. The path is inserted by a coordinate system in the level code and represents the "borders" of the road. </p>
  
  <p>Is this a good way to start a top down racing game? Or are there better ways? How can I "draw" the path over my background image?</p>
