How to move an SKSpriteNode along a horizontal line

I have an SKSpriteNode that can be moved anywhere I am touching, and I want it to move where my finger is, just along a horizontal line so that is cannot move vertically.

class GameScene: SKScene {

var ship = SKSpriteNode()

override func didMoveToView(view: SKView) {
/* Setup your scene here */

let shipTexture = SKTexture(imageNamed: "Evaders Art/EvadersShipVert2.png")

ship = SKSpriteNode(texture: shipTexture)

ship.position = CGPoint(x: CGRectGetMidX(self.frame), y: CGRectGetMidY(self.frame) - 250)

ship.size = CGSize(width: 90, height: 115)

shipTexture.filteringMode = SKTextureFilteringMode.Nearest

ship.zPosition = 2



override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
var nodeTouched = SKNode()
var currentNodeTouched = SKNode()

for touch: AnyObject in touches {
let location = touch.locationInNode(self)

nodeTouched = self.nodeAtPoint(location)
ship.position = location



Here's my code, thanks in advance.

Try this:

ship.position.x = location.x

Currently, you are setting the ship's location to the location of the tap. If you want a consistent y position, only set the x.
