How can I make my level menu scrollable vertically? - swift

I have the following level Menu (as seen below). I would like to make it vertically scrollable, resulting in a total height double that of the screen (full scroll height). How can I achieve this?
Below is the code for the image above:
class LevelMenu: SKScene {
let levelButtonSize = SKSpriteNode(imageNamed: "b1").size
let levelButton1: SKSpriteNode = SKSpriteNode(imageNamed: "b1")
let levelButton2: SKSpriteNode = SKSpriteNode(imageNamed: "b2")
let levelButton3: SKSpriteNode = SKSpriteNode(imageNamed: "b3")
let levelButton4: SKSpriteNode = SKSpriteNode(imageNamed: "b4")
let levelButton5: SKSpriteNode = SKSpriteNode(imageNamed: "b5")
let levelButton6: SKSpriteNode = SKSpriteNode(imageNamed: "b6")
let levelButton7: SKSpriteNode = SKSpriteNode(imageNamed: "b7")
let levelButton8: SKSpriteNode = SKSpriteNode(imageNamed: "b8")
let levelButton9: SKSpriteNode = SKSpriteNode(imageNamed: "b9")
let levelButton10: SKSpriteNode = SKSpriteNode(imageNamed: "b10")
let levelButton11: SKSpriteNode = SKSpriteNode(imageNamed: "b11")
let levelButton12: SKSpriteNode = SKSpriteNode(imageNamed: "b12")
override init(size: CGSize){
super.init(size: size)
let bg = SKSpriteNode(imageNamed: "bg")
backgroundImage.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
self.addChild(bg)
let column1PosX = levelButtonSize.width*cDiff
let column2PosX = levelButtonSize.width*cDiff + levelButtonSize.width*2.0
let column3PosX = levelButtonSize.width*cDiff + levelButtonSize.width*4.0
let row1PosY = self.frame.height - levelButtonSize.width*1.5
let row2PosY = row1PosY - levelButtonSize.height - levelButtonSize.width*rDiff
let row3PosY = row2PosY - levelButtonSize.height - levelButtonSize.width*rDiff
let row4PosY = row3PosY - levelButtonSize.height - levelButtonSize.width*rDiff
levelButton1.position = CGPoint(x: column1PosX, y: row1PosY)
levelButton1.zPosition = 10
self.addChild(levelButton1)
levelButton2.position = CGPoint(x: column2PosX, y: row1PosY)
self.addChild(levelButton2)
levelButton3.position = CGPoint(x: column3PosX, y: row1PosY)
self.addChild(levelButton3)
levelButton4.position = CGPoint(x: column1PosX, y: row2PosY)
self.addChild(levelButton4)
levelButton5.position = CGPoint(x: column2PosX, y: row2PosY)
self.addChild(levelButton5)
levelButton6.position = CGPoint(x: column3PosX, y: row2PosY)
self.addChild(levelButton6)
levelButton7.position = CGPoint(x: column1PosX, y: row3PosY)
self.addChild(levelButton7)
levelButton8.position = CGPoint(x: column2PosX, y: row3PosY)
self.addChild(levelButton8)
levelButton9.position = CGPoint(x: column3PosX, y: row3PosY)
self.addChild(levelButton9)
levelButton10.position = CGPoint(x: column1PosX, y: row4PosY)
self.addChild(levelButton10)
levelButton11.position = CGPoint(x: column2PosX, y: row4PosY)
self.addChild(levelButton11)
levelButton12.position = CGPoint(x: column3PosX, y: row4PosY)
self.addChild(levelButton12)
}
UPDATE
Based on Ron Myschuk's solution, the code below show's what I've been able to achieve and this link shows a .gif of the issue I am having currently, where the screen scrolls too much at the top of the menu.

Here is some code that I use to scroll vertically, I've adapted it to fit your menu. It doesn't perfectly line up to all your items, but it'll give you somewhere to start. And it'll show you how to figure this out on your own.
EDIT: I've updated the code use these funds instead. Still declare your buttons the same way but call my createMenu func to actually create the menu. It is looped so it auto adjusts if you change the number of menu items. the only thing you have to be aware of is; if you add or remove buttons change the array at the top of createMenu accordingly. Also adjust the padding variable to how much vertical space you want between the items
func createMenu() {
let buttons = [levelButton1, levelButton2, levelButton3, levelButton4, levelButton5, levelButton6, levelButton7, levelButton8, levelButton9, levelButton10, levelButton11, levelButton12, levelButton13, levelButton14, levelButton15, levelButton16, levelButton17, levelButton18]

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)

}
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" {

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.

SpriteKit - didBegin contact is called 30 times instead of 1 time

I am making a little FlappyBird clone and have got everything working as it should until I changed the physics body of the bird to be exact to the texture. Now what it does is when it flies through the gap in the pipes it counts 30 points instead of just 1 point.
This only happens when I use the texture exact physics body which I need because the bird isn't round nor rectangular.
How would I go about making the collision so it only collides once with each gap node. I have tried setting the categoryBitBask to 0 after the contact but then all the gaps after don't add to the point count anymore at all.
Here is the full game code:

If you would be using RxSwift, you would be able to easily get rid of those extra events easily by using debounce() or throttle() or distinctUntilChanged(). If you are willing to try this approach, give RxSpriteKit framework a go. Otherwise, store a timestamp of the last contact and ignore the following contacts until some time period elapses.

Leaving equal width gap spacing before and between menu buttons

I have created a scrolling menu using the code below. I am trying to create equal row gaps (width spacing) between each of the menu sprite buttons. Currently, I've been able to leave equal width spacing at the left and right ends but not in between sprite buttons. Please see the relevant code below:
class LevelScene: SKScene {
let levelButtonSize = SKSpriteNode(imageNamed: "b1").size
let levelButton1: SKSpriteNode = SKSpriteNode(imageNamed: "b1")
let levelButton2: SKSpriteNode = SKSpriteNode(imageNamed: "b2")

}
Please note that I set the scene in the following way:
let levelScene = LevelScene(size: CGSize(width:480, height:640))
levelScene.anchorPoint = CGPoint(x: 0.5, y: 0.5)
levelScene.scaleMode = .aspectFill
skView?.presentScene(levelScene)
EDIT
The image below shows a portion of my level menu which has more space between the level buttons as compared to the sides. I want to get the same width gaps between buttons and also at the sides.
I would suggest:
let scaledWidth = levelButtonSize.width/2;
let totalMarginX = self.frame.width - 3*scaledWidth
let marginX = totalMarginX/4
let column1PosX = marginX + scaledWidth/2
let column2PosX = 2*marginX + 3*scaledWidth/2
let column3PosX = 3*marginX + 5*scaledWidth/2

How to create a subview inside an SKScene?

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.

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
//
