Scroll for SpriteKit

  • 772

I'm making a game with Swift, and I have a giant image on a SKSpriteNodemap (similar to the image I attached) and each point is a SKSpriteNodechild, I'm scrolling like this in the function touchesMoved:

let newLocation = touch.locationInNode(self)
let prevLocation = touch.previousLocationInNode(self)
var newYPosition = map.position.y
if (newLocation.y > prevLocation.y) { newYPosition = map.position.y + abs(newLocation.y - prevLocation.y) }
else if newLocation.y < prevLocation.y { newYPosition = map.position.y - abs(newLocation.y - prevLocation.y) }
if newYPosition <= 0 && newYPosition > self.frame.height - map.frame.height{ map.position.y = newYPosition }

But by doing it this way the scroll is slow, it doesn't have the effect that it slows down when I release it, but it stops immediately when I release my finger. How can I do to have something more similar to a real scroll?

    When I lift my finger slow then it stops scrolling, but when I lift my finger fast it scrolls a bit further and stops a bit later.
