Ok so I have a scrollView which has been subclassed to be able to be applied to any scene which is from a previous question I asked here:
SpriteKit, Swift 2.0 - ScrollView in reverse
import Foundation
import SpriteKit
/// Nodes touched
var nodesTouched: [AnyObject] = [] // global
/// Scroll direction
enum ScrollDirection: Int {
case None = 0
case Vertical
case Horizontal
}
class CustomScrollView: UIScrollView {
// MARK: - Static Properties
/// Touches allowed
static var disabledTouches = false
/// Scroll view
private static var scrollView: UIScrollView!
// MARK: - Properties
/// Current scene
private weak var currentScene: SKScene?
/// Moveable node
private var moveableNode: SKNode?
/// Scroll direction
private var scrollDirection = ScrollDirection.None
// MARK: - Init
init(frame: CGRect, scene: SKScene, moveableNode: SKNode, scrollDirection: ScrollDirection) {
print("Scroll View init")
super.init(frame: frame)
CustomScrollView.scrollView = self
self.scrollDirection = scrollDirection
self.currentScene = scene
self.moveableNode = moveableNode
self.frame = frame
indicatorStyle = .White
scrollEnabled = true
//self.minimumZoomScale = 1
//self.maximumZoomScale = 3
canCancelContentTouches = false
userInteractionEnabled = true
delegate = self
// flip for spritekit (only needed for horizontal)
if self.scrollDirection == .Horizontal {
let flip = CGAffineTransformMakeScale(-1,-1)
self.transform = flip
}
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
// MARK: - Touches
extension CustomScrollView {
/// began
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
print("Touch began scroll view")
guard !CustomScrollView.disabledTouches else { return }
currentScene?.touchesBegan(touches, withEvent: event)
}
/// moved
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
print("Touch moved scroll view")
guard !CustomScrollView.disabledTouches else { return }
currentScene?.touchesMoved(touches, withEvent: event)
}
/// ended
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
print("Touch ended scroll view")
guard !CustomScrollView.disabledTouches else { return }
currentScene?.touchesEnded(touches, withEvent: event)
}
/// cancelled
override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
print("Touch cancelled scroll view")
guard !CustomScrollView.disabledTouches else { return }
currentScene?.touchesCancelled(touches, withEvent: event)
}
}
// MARK: - Touch Controls
extension CustomScrollView {
/// Disable
class func disable() {
print("Disabled scroll view")
CustomScrollView.scrollView?.userInteractionEnabled = false
CustomScrollView.disabledTouches = true
}
/// Enable
class func enable() {
print("Enabled scroll view")
CustomScrollView.scrollView?.userInteractionEnabled = true
CustomScrollView.disabledTouches = false
}
}
// MARK: - Delegates
extension CustomScrollView: UIScrollViewDelegate {
/// did scroll
func scrollViewDidScroll(scrollView: UIScrollView) {
print("Scroll view did scroll")
if scrollDirection == .Horizontal {
moveableNode!.position.x = scrollView.contentOffset.x
} else {
moveableNode!.position.y = scrollView.contentOffset.y
}
}
}
The only problem is that the scrollview uses pages, while, the way I want it to look, scrolls only through the sprites, like the raywenderlich one where all the sprites are the only things moving and so I don't have to scroll across multiple pages to get to a sprite.
the project can be found here:
Raywenderlich Project
Because they use their gameViewController I am having trouble figuring out how to implement it through a subclass scrollview like I have above.
