Swift SpriteKit:当我点击时背景加速?

我一直在做这个游戏,并为我的精灵继续前行,但每当我点击精灵跳跃时,地面逐渐加速,每次点击都会以一种荒谬的速度加速,我不想要它去做这个。我该如何解决?

这是我的代码:

类MCTGround:SKSpriteNode {

item

编辑:我的touchesBegan功能:

let numberOfSegments = 21
let colorOne = UIColor(red: 88.0/255.0, green: 148.0/255.0, blue:87.0/255.0, alpha: 1.0)
let colorTwo = UIColor(red: 120.0/255.0, green: 195.0/255.0, blue: 118.0/255.0, alpha: 1.0)
init(size: CGSize) {
    super.init(texture: nil, color: UIColor.brownColor(), size: CGSizeMake(size.width * 2, size.height))
    anchorPoint = CGPointMake(0, 0.5)

    for var i = 0; i < numberOfSegments; i++ {
        var segmentColor: UIColor!

        if i  % 2 == 0 {
            segmentColor = colorOne

        } else {
            segmentColor = colorTwo
        }
        let segment = SKSpriteNode(color: segmentColor, size: CGSizeMake(self.size.width / CGFloat(numberOfSegments), self.size.height))
        segment.anchorPoint = CGPointMake(0.0, 0.5)
        segment.position = CGPointMake(CGFloat(i) * segment.size.width, 0)
        addChild(segment)

    }

 }

 required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
 }

func start() {
    let moveLeft = SKAction.moveByX(-frame.size.width / 2, y: 0, duration: 1.0)
    let resetPosition = SKAction.moveToX(0, duration: 0)
    let moveSequence = SKAction.sequence([moveLeft, resetPosition])

        runAction(SKAction.repeatActionForever(moveSequence))



    }


}

这是因为您每次都会向后台添加其他操作。只是做:

var hasBegun = false
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
    jumpPlayer()
    if !hasBegun {
        hasBegun = true
        movingGround.start()
        fruitGenerator.startGeneratingFruitEvery(3)
    }

    ...

或仅运行那些&#34; start&#34; -type方法一次的任何其他方法。
