Question

所以我正在制作游戏，之前使用左右按钮移动。我正在考虑将其更改为类似于此http://gyazo.com/05b6079862874a282ad14220e7267bd1的自定义类型的滑块我不知道如何让它更新触摸开始，所以请注册滑动手指。到目前为止我所拥有的是：

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {


        for touch: AnyObject in touches {

            let location = touch.locationInNode(self)

            if self.nodeAtPoint(location) == self.sliderBox{

                let move = touch.locationInNode(self)
                slider.position.x = move.x


        }
}

这会让红点移动到我触摸的位置，但是我需要能够像这样，并且能够在按住它时滑动。感谢您抽出宝贵时间来研究这个问题。

通过更改覆盖func touchesBegan到func touchesMoved

来修复

override func touchesMoved(touches: NSSet, withEvent event: UIEvent) {
    for touch: AnyObject in touches {

        let location = touch.locationInNode(self)

        if self.nodeAtPoint(location) == self.slider{


            let move = touch.locationInNode(self)
            slider.position.x = move.x



        }
    }
}
