SpriteKit game lag when the function touchesBegan is called - swift

I'm creating my first game, similar to flappy bird. I want it to start when the screen is touched like the real game. But it lags for about a second and an half, the result is that you die without even playing. Here is my code:
override func didMoveToView(view: SKView) {
/* Setup your scene here */
//Here i init some stuff
distanceToMove = CGFloat(self.frame.size.width + 140)
movePipes = SKAction.repeatActionForever(SKAction.moveByX(-distanceToMove, y: 0, duration: NSTimeInterval(1.2)))
removePipes = SKAction.removeFromParent()
moveAndRemove = SKAction.sequence([movePipes,removePipes])
let delay = SKAction.waitForDuration(NSTimeInterval(0.6))
let spawn = SKAction.runBlock({() in self.initPipes()})
let spawnAndDelay = SKAction.sequence([spawn,delay])
spawnAndDelayForever = SKAction.repeatActionForever(spawnAndDelay)
}
TouchesBegan:
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
/* Called when a touch begins */
let touch = touches.first! as UITouch!
let touchLocation = touch.locationInNode(self)
if state == GameState.Starting {
state = GameState.Playing
instNode.hidden = true
if state == GameState.Playing {
runAction(spawnAndDelayForever)
addChild(pipes)
initScore()
}
}
Pipes init:
func initPipes() {
let upper = UInt32(self.size.height - 250)
let pY = arc4random_uniform(upper) + 200
let pipePair = SKNode()
pipePair.position = CGPoint(x: self.frame.size.width + 70, y: 0)
//PIPE 1
let pipe1 = SKSpriteNode(color: SKColor.whiteColor(), size: CGSizeMake(70, 700))
pipe1.anchorPoint = CGPointMake(0, 0)
pipe1.position = CGPoint(x: 0, y: Int(pY))
pipe1.physicsBody = SKPhysicsBody(rectangleOfSize: CGSizeMake(70, 700), center: CGPointMake(70/2, 700/2))
pipe1.physicsBody?.dynamic = false
pipe1.physicsBody?.affectedByGravity = false
pipe1.physicsBody?.categoryBitMask = PipeCategory
pipe1.physicsBody?.contactTestBitMask = PlayerCategory
pipe1.physicsBody?.collisionBitMask = PlayerCategory
pipePair.addChild(pipe1)
//PIPE 2
let pipe2 = SKSpriteNode(color: SKColor.whiteColor(), size: CGSizeMake(70, 700))
pipe2.anchorPoint = CGPointMake(0,1)
pipe2.position = CGPoint(x: 0, y: pipe1.position.y - 150)
pipe2.physicsBody = SKPhysicsBody(rectangleOfSize: CGSizeMake(70, 700), center: CGPointMake(35, -700/2))
pipe2.physicsBody?.dynamic = false
pipe2.physicsBody?.affectedByGravity = false
pipe2.physicsBody?.categoryBitMask = PipeCategory
pipe2.physicsBody?.contactTestBitMask = PlayerCategory
pipe2.physicsBody?.collisionBitMask = PlayerCategory
pipePair.addChild(pipe2)
//SCORE
let scoreSprite = SKSpriteNode(color: SKColor.clearColor(), size: CGSize(width: 50, height: 150))
scoreSprite.anchorPoint = CGPointMake(0, 1)
scoreSprite.position = CGPointMake(pipe1.position.x + 10, pipe1.position.y)
scoreSprite.physicsBody = SKPhysicsBody(rectangleOfSize: CGSize(width: 50, height: 150), center: CGPointMake(25, -75))
scoreSprite.physicsBody?.categoryBitMask = GapCategory
scoreSprite.physicsBody?.contactTestBitMask = PlayerCategory
scoreSprite.physicsBody?.collisionBitMask = 0
scoreSprite.physicsBody?.dynamic = false
pipePair.addChild(scoreSprite)
pipePair.runAction(moveAndRemove)
pipes.addChild(pipePair)
}
It's pretty simple: in initPipes() i create the pipes and i run the action of moving and removing. In touchesBegan i call the action of spawning them.. But it's laggy when i touch the screen.

Run your app through the Time Profiler Instrument to find out where the lag is coming from. It'll give you detailed results (down to individual lines of code) that'll let you know where your issues are.
That'll be much more accurate than people on here guessing.

In swift for spritekit, how would I change the textures of nodes when they are placed?

I’m currently working on a matching game and when the user touches the nodes (Fruit match cards) I want them to display different images when a user clicks the nodes (Fruit match cards).
This is my current code:
import Foundation
import SpriteKit
class EasyScreen: SKScene {
override func didMove(to view: SKView) {
var background = SKSpriteNode(imageNamed: "Easy Screen Background")
let timerText = SKLabelNode(fontNamed: "Arial")
timerText.fontSize = 40
timerText.fontColor = SKColor.white
timerText.position = CGPoint(x: 20, y: 400)
timerText.zPosition = 1
var counter:Int = 120
timerText.run(
SKAction.repeatForever(
SKAction.sequence(
[
SKAction.run {
counter -= 1
timerText.text = " Time: \(counter)"
print("\(counter)")
if counter <= 0 {
let newScene = TryAgainScreen(fileNamed: "Try Again Screen")
newScene?.scaleMode = .aspectFill
self.view?.presentScene(newScene)
}
},
SKAction.wait(forDuration: 1)
]
)
)
)
background.position = CGPoint(x: 0, y: 0)
background.size.width = self.size.width
background.size.height = self.size.height
background.anchorPoint = CGPoint(x: 0.5,y: 0.5)
let matchCardOne = SKSpriteNode(imageNamed: "Fruit Match Card")
let matchCardTwo = SKSpriteNode(imageNamed: "Fruit Match Card")
let matchCardThree = SKSpriteNode(imageNamed: "Fruit Match Card")
let matchCardFour = SKSpriteNode(imageNamed: "Fruit Match Card")
matchCardOne.name = "FruitMatchCard1"
matchCardTwo.name = "FruitMatchCard2"
matchCardThree.name = "FruitMatchCard3"
matchCardFour.name = "FruitMatchCard4"
matchCardOne.size = CGSize(width: 150, height: 300)
matchCardTwo.size = CGSize(width: 150, height: 300)
matchCardThree.size = CGSize(width: 150, height: 300)
matchCardFour.size = CGSize(width: 150, height: 300)
matchCardOne.zPosition = 1
matchCardTwo.zPosition = 1
matchCardThree.zPosition = 1
matchCardFour.zPosition = 1
matchCardOne.anchorPoint = CGPoint(x: 0.5, y: 0.5)
matchCardTwo.anchorPoint = CGPoint(x: 0.5, y: 0.5)
matchCardThree.anchorPoint = CGPoint(x: 0.5, y: 0.5)
matchCardFour.anchorPoint = CGPoint(x: 0.5, y: 0.5)

addChild(matchCardOne)
addChild(matchCardTwo)
addChild(matchCardThree)
addChild(matchCardFour)
addChild(timerText)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
self.view?.isMultipleTouchEnabled = false
let touch = touches.first
let positionInScene = touch!.location(in: self)
let touchedCardOneNode = self.atPoint(positionInScene)
if let name = touchedCardOneNode.name {
if name == "FruitMatchCard1" {
let newTexture = SKTexture(imageNamed: "Apple")
FruitMatchCard1.init(texture: newTexture)
}
}

}
let touchThree = touches.first
let positionInSceneThree = touch!.location(in: self)
let touchedCardThreeNode = self.atPoint(positionInScene)
if let name = touchedCardThreeNode.name {
if name == "FruitMatchCard3" {

if name == "FruitMatchCard4" {
FruitMatchCard4.init(imageNamed: "Banana")
}
}
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
}
I’m trying to change the textures of the nodes in this part of the code. Inside the “if name == “FruitMatchCard” { } “ part of the code. However, when I launch the Xcode simulator the node’s textures aren't changing.
Any advice on how I can do this? Thanks!
Your fundamental problem is that when someone taps a card, you are creating a new card with the new texture and not doing anything with it. Take the following code you have:
FruitMatchCard2.init(imageNamed: "Banana")
This code creates a match card, but you don't do anything with the card.
To change the texture of the card, you must get the sprite node of the tapped card and change its texture. I see in your code you have the following variable:
let touchedCardTwoNode = self.atPoint(positionInScene)
This variable has the card that was touched. Set its texture to the texture you want to use.
touchedCardTwoNode.texture = SKTexture(imageNamed: "Banana")
My SpriteKit is a bit rusty so I can't guarantee that example will compile, but it gives you an idea of what you need to do to change the texture when tapping a card.

Trail of nodes along a path as in hello world

hi I have a node traveling back and forth along a path. I am trying to integrate the moving shapeNode as in the hello world example to trail my moving node. I'm using a trigger from frame update to trigger the copying of the shape node. And using the position of the travelling node.
The problem is that the trail has some sort of offset and i don't know where its coming from. I have tried to compensate but to no avail. I'm wondering if it might have anything to do with the actions. Thanks for reading.
I have tried looking at this link but i cannot translate

How to track two different collisions in SpriteKit Swift

I have seen many methods on the internet, but I'm still very confused on how this is done. Ive legitimately have spent 3 hours yesterday on trying to acomplish this, but anyway the question I have is I have 3 main SKSpriteNodes in my game: man, ground, and arrow. Im trying to make it so that when the man jumps he is only able to jump once until returning back to the ground. My plan is to have it so that when the jump button is pressed a condition is changed and won't be changed back till the man hits the ground again. Im also trying to make it so that when an arrow contacts him it will be a game over and run a line of code. This is the code I have so far

Spritekit - Increasing speed and keeping the same distance between sprite nodes?

I am having an issue where my platforms distance becomes messed up after a certain score has been reached. I want the game to start just like the spawnDelayForever part in the touchesBegan until the score reaches 5. After the score reaches 5…10…15 and so on, I want the platforms to be able to speed up with the same amount of space in between each spawn no matter what. The issue is when the score reaches 5, the platforms speed but the distance/space in between each spawn is not the same. They are further apart. Can anybody help me?
Hopefully this didn’t confuse anyone but if it did let me clarify it. I just want the platforms to speed up after a certain score has been reached with the same amount of space between each spawn. Meaning the waitForDuration should speed up (less than 2.0) with each speed increase.
Part of my code:
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
/* Called when a touch begins */
if gameStarted == false {
gameStarted = true
ball.physicsBody?.affectedByGravity = true
title.removeFromParent()
let spawn = SKAction.runBlock({
()in
self.creatingPlatforms()
})
let delay = SKAction.waitForDuration(2.0)
let spawnDelay = SKAction.sequence([spawn, delay])
let spawnDelayForever = SKAction.repeatActionForever(spawnDelay)
self.runAction(spawnDelayForever)
let distance = CGFloat(self.frame.width + 170 + officialPlatform.frame.width)
let movePlatforms = SKAction.moveByX(-distance, y: 0, duration: NSTimeInterval(0.01 * distance))
let removePlatforms = SKAction.removeFromParent()
moveAndRemove = SKAction.sequence([movePlatforms, removePlatforms])
ball.physicsBody?.velocity = CGVectorMake(0, 0)
ball.physicsBody?.applyImpulse(CGVectorMake(0, 0))
scoreLbl.fontSize = 35
scoreLbl.position = CGPoint(x: self.frame.width / 2, y: scene!.frame.height / 2 + 300)
scoreLbl.fontColor = UIColor.blackColor()
scoreLbl.text = "\(score)"
score = 0
self.addChild(scoreLbl)
}
else {
ball.physicsBody?.velocity = CGVectorMake(0, 0)
ball.physicsBody?.applyImpulse(CGVectorMake(0, 45))
ball.physicsBody?.restitution = 0
scoreNode.physicsBody?.restitution = 0
}
}
func creatingPlatforms() {
scoreNode = SKSpriteNode()
scoreNode.size = CGSize(width: 120, height: 25)
scoreNode.position = CGPoint(x: self.frame.width + 95, y: self.frame.height / 2)
scoreNode.physicsBody = SKPhysicsBody(rectangleOfSize: scoreNode.size)
scoreNode.physicsBody?.affectedByGravity = false
scoreNode.physicsBody?.dynamic = false
scoreNode.physicsBody?.categoryBitMask = physicsCategory.score
scoreNode.physicsBody?.collisionBitMask = 0
scoreNode.physicsBody?.contactTestBitMask = physicsCategory.ball
scoreNode.name = "scoreNode"
officialPlatform = SKNode()
let platform = SKSpriteNode(imageNamed: "platform")
platform.size = CGSize(width: 140, height: 25)
platform.position = CGPoint(x: self.frame.width + 95, y: self.frame.height / 2)
platform.physicsBody = SKPhysicsBody(rectangleOfSize: platform.size)
platform.physicsBody?.categoryBitMask = physicsCategory.platform
platform.physicsBody?.collisionBitMask = physicsCategory.ball
platform.physicsBody?.contactTestBitMask = physicsCategory.ball
platform.physicsBody?.affectedByGravity = false
platform.physicsBody?.dynamic = false
officialPlatform.name = "official platform"
officialPlatform.runAction(moveAndRemove)
officialPlatform.addChild(platform)
officialPlatform.addChild(scoreNode)
self.addChild(officialPlatform)
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
if score >= 5 && score <= 9 {
moveAndRemove.speed = 0.9
}
}
}
I found my answer in another question on here.
swift - Increase speed of objects over time
I changed my self.runAction(spawnDelayForever) in my touchesBegan to self.runAction(spawnDelayForever, withKey: "spawnDelayForever"). Then in the update function, I changed it to:
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
if score > 0 {
self.actionForKey("spawnDelayForever")?.speed += 0.001
moveAndRemove.speed += 0.001
}
}

Stopping the countUp speed rate

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.

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])))
}
}
