Stopping the countUp speed rate - swift

Question

I just started to learn Swift and Sprite Kit. I need assistance with the following code.
I have a countUp that when the ball is touched the countUp starts but my problem is that every time I tap the ball the rate of speed in the countUp increases. I want the CountUp to be stable. Any help will be appreciated.
class Game: SKScene {
var Ball = SKSpriteNode(imageNamed: "Red.png")
var QuitOption = SKLabelNode()
var ScoreLabel = SKLabelNode()
var timescore = Int()
var timesecond = Int()
override func didMoveToView(view: SKView) {
backgroundColor = SKColor.blackColor() // background for the display
self.physicsWorld.gravity = CGVectorMake(0, -9.8)
let SceneBody = SKPhysicsBody(edgeLoopFromRect: self.frame)
SceneBody.friction = 0
self.physicsBody = SceneBody
Ball.size = CGSize(width: 120, height: 120)
Ball.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height*0.7)
Ball.physicsBody = SKPhysicsBody(circleOfRadius: 60)
Ball.physicsBody?.affectedByGravity = true
Ball.physicsBody?.restitution = 0.5
Ball.physicsBody?.linearDamping = 0
Ball.name = "Ball"
self.addChild(Ball)
QuitOption.text = "Quit"
QuitOption.fontName = "Noteworthy-Light"
QuitOption.fontColor = SKColor.greenColor()
QuitOption.fontSize = 35
QuitOption.position = CGPoint(x: self.frame.size.width/2 - 160, y: self.frame.size.height*1 - 110)
QuitOption.name = "Quit"
addChild(QuitOption)
ScoreLabel = SKLabelNode(fontNamed: "Noteworthy-Light")
ScoreLabel.fontSize = 50 // The + will move it to the right side and - to the left side for more accuracy.
ScoreLabel.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height/4 + 400) // position of ScoreLabelNode
ScoreLabel.name = "Score+"
ScoreLabel.hidden = false
self.addChild(ScoreLabel)
}
// Making the ball jump after user touches ball
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
var touch = touches.first as! UITouch
var location = touch.locationInNode(self)
var node = self.nodeAtPoint(location)
if (node.name == "Quit"){
let myScene = GameScene(size: self.size)
myScene.scaleMode = scaleMode
let reveal = SKTransition.fadeWithDuration(1)
self.view?.presentScene(myScene, transition: reveal)
}
if (node.name == "Ball"){
for touch: AnyObject in touches {
let location = touch.locationInNode(self)
Ball.physicsBody?.allowsRotation = true
Ball.physicsBody?.velocity = CGVectorMake(0, 0)
Ball.physicsBody?.applyImpulse(CGVectorMake(0, 100))
}
}
var actionwait = SKAction.waitForDuration(0.5)
var actionrun = SKAction.runBlock({
self.timescore++
self.timesecond++
if self.timesecond == 60 {self.timesecond = 0}
self.ScoreLabel.text = " \(self.timescore/60):\(self.timesecond)"})
ScoreLabel.runAction(SKAction.repeatActionForever(SKAction.sequence([actionwait,actionrun])))
}
}

Answer 1

I guess that's happening because you are running same block over and over again after every touch. To ensure you run block only once, you can use some Bool indicator and after the first run, set its value appropriately, like this:
if(!self.locked){
self.locked = true // at start, this value should be false
var actionrun = SKAction.runBlock({
self.timescore++
self.timesecond++
if self.timesecond == 60 {self.timesecond = 0}
self.ScoreLabel.text = " \(self.timescore/60):\(self.timesecond)"})
ScoreLabel.runAction(SKAction.repeatActionForever(SKAction.sequence([actionwait,actionrun])))
}
}
