I am new to SpriteKit, and I am creating a game where I have designed the main menu with sketch and apply the image to spritekit as my background image. Everytime I put a label/text above the button images. It doesn't work properly. When they tap on play lets say, they will play and when they lose, and start over all of sudden the labels disappear.
Here is an image:
Here is my code
//creating the start game programmatically.
let dw_startButton = SKSpriteNode()
dw_startButton.name = "dw_startbutton"
dw_startButton.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
self.addChild(dw_startButton)
//Instructions Button
let dw_selector = SKSpriteNode()
dw_selector.name = "dw_selector"
dw_selector.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
self.addChild(dw_selector)
//Starting text
let startText = SKLabelNode(text: "Play!")
startText.fontColor = UIColor.white
startText.position = CGPoint(x: 50, y: 50)
startText.fontSize = 45
startText.fontName = "Helvetica-Bold"
startText.verticalAlignmentMode = SKLabelVerticalAlignmentMode(rawValue: 1)!
startText.name = "dw_startbutton"
dw_startButton.addChild(startText)
//instructions text
let startTexts = SKLabelNode(text: "Insturctions")
startTexts.fontColor = UIColor.white
startTexts.position = CGPoint(x: 0, y: 0)
startTexts.fontSize = 20
startTexts.fontName = "Helvetica-Bold"
startTexts.verticalAlignmentMode = SKLabelVerticalAlignmentMode(rawValue: 1)!
startTexts.name = "dw_selector"
dw_selector.addChild(startTexts)
You always need to add zPosition to your sprites and labels. Otherwise sometimes they will appear and other times they may appear behind the background
//creating the start game programmatically.
let dw_startButton = SKSpriteNode()
dw_startButton.zPosition = 1
dw_startButton.name = "dw_startbutton"
dw_startButton.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
self.addChild(dw_startButton)

I've been searching the internet for a while now and I couldn't come up with any solution.
I've created a SKLabelNode in my SpriteKit project which displays level numbers.
SKLabelNode:
let levelLbl = SKLabelNode(fontNamed: "LEMON-Bold")
levelLbl.text = "1"
levelLbl.fontSize = 100
levelLbl.fontColor = .grey
levelLbl.zPosition = 2
levelLbl.horizontalAlignmentMode = .center
levelLbl.verticalAlignmentMode = .center
levelLbl.position = CGPoint(x: frame.midX, y: frame.height * 0.75)
addChild(levelLbl)

I want to fill up the number of my label smoothly with white color from the bottom to the top with an animation so that after x seconds the label is completely white.
I don't want the color to fade in but rather to be filled up similar to a cup of water.
It would be amazing if someone could help me out here!
This is how far I came by using a SKCropNode. My problem is I don't know why I don't see an animation:
func labelAnimation() {
let levelLbl = SKLabelNode(fontNamed: "LEMON-Bold")
let blackRect = SKShapeNode(rectOf: CGSize(width: levelLbl.frame.width, height: levelLbl.frame.height))
blackRect.fillColor = .grey
blackRect.strokeColor = .grey
blackRect.position = CGPoint(x: 0, y: levelLbl.frame.height / 2)
let whiteRect = SKShapeNode(rectOf: CGSize(width: levelLbl.frame.width, height: levelLbl.frame.height))
whiteRect.fillColor = .white
whiteRect.strokeColor = .white
whiteRect.position = CGPoint(x: 0, y: -levelLbl.frame.height / 2)
//Level Node
levelNode.position = CGPoint(x: 0, y: 0)
levelNode.addChild(blackRect)
levelNode.addChild(whiteRect)
//Mask Node
levelLbl.text = "\(levelNr)"
levelLbl.fontSize = 100
levelLbl.horizontalAlignmentMode = .center
levelLbl.verticalAlignmentMode = .center
//Crop Node
cropNode.addChild(levelNode)
cropNode.maskNode = levelLbl
cropNode.position = CGPoint(x: frame.midX, y: frame.midY)
cropNode.zPosition = 5
addChild(cropNode)
//action
let movelevelNode = SKAction.move(to: CGPoint(x: 0, y: frame.height / 3), duration: 8)
levelNode.run(movelevelNode)
}
I have a rectangle and I want to cut it out by a line.
I can cut it out by another rectangle etc.. but not with a line.
I set the linewidth on 20 and use the exact same code as I do always but I really can't figure out how to do it with a line.
Here is my code:
let total = CALayer()
total.frame = UIScreen.main.bounds
let path1 = UIBezierPath(rect: UIScreen.main.bounds)
let path2 = UIBezierPath()
path2.move(to: CGPoint(x: 30, y: 30))
path2.addLine(to: CGPoint(x: 30, y: 100))
path2.lineWidth = 20
path1.append(path2)
path1.usesEvenOddFillRule = true
let bgLayer = CAShapeLayer()
bgLayer.path = path1.cgPath
bgLayer.fillColor = UIColor.black.cgColor
bgLayer.fillRule = kCAFillRuleEvenOdd
total.addSublayer(bgLayer)
imageview.layer.mask = total
Before "Buy Ship" is pressed So I am trying to create a shop where players can buy new ships. When the player hits the "buy button" image I want a combination of images and texts to become visible which acts as a sort of conformation screen. Hopefully you can see here what I mean. I would also greatly appreciate if you could tell me how to dim everything besides the conformation box. After "Buy Ship" is pressed.
This is what my code looks like so far:

As Whirlwind said in his comment you can create an SKNode to the center of your scene (position CGPoint.zero) prepare it with all your stuff and hide it with the alpha properties set to 0 and put it's zPosition to -1 (under all the other visible nodes of your scene).
So when you button will be pressed, you simply change the zPosition to an highest value and the alpha to 1. To make more realistic these action s you could use some animations like:
extension UIView {
func fadeIn(_ duration:TimeInterval=1.0) {
UIView.animate(withDuration: duration, delay: 0.0, options: UIViewAnimationOptions.curveEaseIn, animations: {
self.alpha = 1.0 // Instead of a specific instance of, say, birdTypeLabel, we simply set [thisInstance] (ie, self)'s alpha
}, completion: nil)
}
func fadeOut(_ duration:TimeInterval=1.0) {
UIView.animate(withDuration: duration, delay: 0.0, options: UIViewAnimationOptions.curveEaseOut, animations: {
self.alpha = 0.0
}, completion: nil)
}
}
I have figured out how to get the conformation screen to work. Thanks to #AlessandroOrnano for all the help! I have attached my code below for future reference. If anyone has a more efficient way of doing this I would greatly appreciate any suggestions.

For additional shop pages just copy and paste these sets of codes. With the exception of changing the the tapped nodes around to the correct order in which you wish to move from page to page.
Everything is fine until I use NSTimer to run the tree, that the images of tree is gone. I use SKview to show the physic then I find out that the code is still run, just only the image is gone. How can I fix it?

If I understood your question correctly, then you want to know why your "tree" is gone.
It appears that your MakeTree() method moves all the tree sprite nodes off the screen:
var treemove = SKAction.moveByX(0, y: -self.frame.size.width*2, duration: NSTimeInterval(self.frame.size.height/50))
Also, you shouldn't use NSTimers in SpriteKit. Use SKAction.waitForDuration instead. Like this:
let delay = SKAction.waitForDuration(3)
someNode.runAction(delay) {
//run code here after 3 seconds
}
i've a problem with my swift game. I want to spawn every 2 seconds two sprites and move them like flappy bird pipes. I tried on this way but my game crashes after the delay. Here is DidMoveToView: ( i jump right on the interesting parts)
let distanceToMove = CGFloat(self.frame.size.width + 140)
let movePipes = SKAction.repeatActionForever(SKAction.moveByX(-distanceToMove, y: 0, duration: NSTimeInterval(0.01 * distanceToMove)))
let removePipes = SKAction.removeFromParent()
moveAndRemove = SKAction.sequence([movePipes,removePipes])
let delay = SKAction.waitForDuration(NSTimeInterval(2.0))
let spawn = SKAction.runBlock({() in self.initPipes()})
let spawnAndDelay = SKAction.sequence([spawn,delay])
let spawnAndDelayForever = SKAction.repeatActionForever(spawnAndDelay)
runAction(spawnAndDelayForever)
And here is the func of the pipes:
func initPipes() {
let pY = arc4random_uniform(UInt32(self.size.height - 250) + 250)
let pipePair = SKNode()
pipePair.position = CGPoint(x: self.frame.size.width + 70, y: 0)
//PIPE 1
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
pipePair.addChild(pipe1)
//PIPE 2
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
pipePair.addChild(pipe2)
pipePair.runAction(moveAndRemove)
addChild(pipePair)
}
Any idea? Thanks
I think your issue is here
pipePair.addChild(pipe1)
You are not creating a new pipe but instead using an old one you created somewhere else. The first time through you are not going to have a problem, but if you didn't remove the pipe1 from its parent before you try adding it to a new parent it will crash. I would create your pipe1 and pipe2 in that method instead of having a variable outside of it.
func initPipes() {
let pY = arc4random_uniform(UInt32(self.size.height - 250) + 250)
let pipePair = SKNode()
pipePair.position = CGPoint(x: self.frame.size.width + 70, y: 0)
//PIPE 1
let pipe1 = //whatever pipe1 is
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
pipePair.addChild(pipe1)
//PIPE 2
let pipe2 = //whatever pipe1 is
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
pipePair.addChild(pipe2)
pipePair.runAction(moveAndRemove)
addChild(pipePair)
}
or if the intention is to only have one set of pipes at a time call
pipe1.removeFromParent()
pipe2.removeFromParent()
before
pipePair.addChild(pipe1)
pipePair.addChild(pipe2)
Hopefully that makes sense and is helpful.
