Question

这是我第一次来，我只用了2个月的时间。我正在制作一个目标随机产生的游戏，并且为每个目标触摸它时，其得分会增加+1。现在，我想知道当分数达到选定值时是否有增加目标生成速度的方法。我尝试过使用“ if”，但是我认为只要更改值就启用永远重复，就可以避免。

有解决方案吗？寻求帮助，如果我的代码不是最好的，抱歉，但是正如我所说的，我只是在学习:)

GameScene类：SKScene {

var time = 5{
    didSet {
        timeLabel.text = "\(time)"
    }
}
var timeLabel: SKLabelNode!

var scoreLabel: SKLabelNode!
var score = 0 {
    didSet {
        scoreLabel.text = "Score: \(score)"
    }
}

override func didMove(to view: SKView) {

    timeLabel = SKLabelNode(fontNamed: "Chalkduster")
    timeLabel.color = .white
    timeLabel.text = "5"
    timeLabel.fontSize = 70
    timeLabel.horizontalAlignmentMode = .left
    timeLabel.position = CGPoint(x:200 , y: 410)
    addChild(timeLabel)

    scoreLabel = SKLabelNode(fontNamed: "Chalkduster")
    scoreLabel.color = .white
    scoreLabel.text = "Score: 0"
    scoreLabel.horizontalAlignmentMode = .right
    scoreLabel.position = CGPoint(x:390 , y: 820)
    addChild(scoreLabel)

    backgroundColor = SKColor.black


    let spawn = SKAction.run({
    ()in
        self.addTarget()
})
    var delay = SKAction.wait(forDuration: 2.5)
    let spawndelay = SKAction.sequence([spawn,delay])
    let spawnforever = SKAction.repeatForever(spawndelay)
    self.run(spawnforever)


    Timer.scheduledTimer(withTimeInterval: 1, repeats: true) { timer in
              self.time -= 1
              if self.time < 1 {
                self.timeLabel.alpha = 0.0
                  timer.invalidate()
              }
          }

}

func random() -> CGFloat {
  return CGFloat(Float(arc4random()) / Float(UINT32_MAX))
}

func random(min: CGFloat, max: CGFloat) -> CGFloat {
  return random() * (max - min) + min
}

func addTarget() {

  // Create sprite
  let target = SKSpriteNode(imageNamed: "Target")
    target.size = CGSize(width: 80, height: 81)
    target.name = "targ"
  // Determine where to spawn the monster along the Y axis
  let actualY = random(min: 70, max: 700)
  let actualX = random(min: 50, max: 350)

  // Position the monster slightly off-screen along the right edge,
  // and along a random position along the Y axis as calculated above
  target.position = CGPoint(x: actualX, y: actualY)

  // Add the monster to the scene
  addChild(target)

    target.run(
           SKAction.sequence([
            SKAction.wait(forDuration: 13.0),
               SKAction.removeFromParent()
           ])
       )
    if score == 20{
        self.enumerateChildNodes(withName: "targ") {
               node, stop in
            node.run(SKAction.removeFromParent())
        }
    }
}

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {

    for touch in touches {
        let location = touch.location(in: self)
        let touchedNode = self.atPoint(location)
        if touchedNode.name == "targ"{
            touchedNode.removeFromParent()
            score += 1
            break;
        }
    }
}

}

得分>时，更改SKAction.waitforduration的值（永久重复），不起作用
