如何沿水平线移动 SKSpriteNode

Question

我有一个 SKSpriteNode 可以移动到我触摸的任何地方，我希望它移动到我手指所在的位置，只是沿着水平线移动，这样就不能垂直移动。

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





    self.addChild(ship)



}

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

    }

}

这是我的代码，提前致谢。

试试这个：

ship.position.x = location.x

当前，您正在将船的位置设置为水龙头的位置。如果你想要一个一致的 y 位置，只设置 x.
