Accessing element in array, saving it and overwriting it - arrays

Question

My Goal: to access an element in an SKnode array and its property between my two scenes and also save and retrieve it the array that contains my achievement SKNodes that hold different values.
So I have two scenes one that is my actual game scene and the second one being my achievements menu that contains the list of all my achievements. When the achievementMenu scene starts it produces 27 Achievements which are a subclass of SKNode called “Achievements” which is seen below”
It is made in a func like so:
for _ in 0...0 {
let Counter = 0
let Achievement = Achievements()
Achievement.achCounter = Counter
Achievement.getAchievementProperties()
Achievement.position = CGPoint(x: self.frame.midX, y: self.frame.midY)
Achievement.zPosition = 100
Achievement.name = "Ach0"
Achievements3.append(Achievement)
moveableArea.addChild(Achievement)
}
Here is the Subclass of the SKNode that holds all the achievements Properties:
class Achievements: SKNode {
//Nodes used throughout the SKNode class
var achievementLabel = SKLabelNode()
var achievementTitleLabel = SKLabelNode()
var achievementNode = SKSpriteNode()
//Counter used to determine the Achievements properties
var achCounter = 0
//Amount Variables used as Achievement Properties
var image: String = "locked"
var information: String = ""
var title: String = ""
var amount = 0
var neededAmount = 0
var incrementAmount = 0
var incrementAmount2 = 0
var stage = 0
func createAchievement() {
let tex:SKTexture = SKTexture(imageNamed: image)
achievementNode = SKSpriteNode(texture: tex, color: SKColor.black, size: CGSize(width: 75, height: 75)) //frame.maxX / 20, height: frame.maxY / 20))
achievementNode.zPosition = -10
achievementNode.name = "AchievementNode"
self.addChild(achievementNode)
self.zPosition = -11
createAchievementLabels()
}
func createAchievementLabels() {
achievementTitleLabel = SKLabelNode(fontNamed: "Avenir-Black")
achievementTitleLabel.fontColor = UIColor.black;
achievementTitleLabel.fontSize = 13 //self.frame.maxY/30
achievementTitleLabel.position = CGPoint (x: 0, y: 45)
achievementTitleLabel.text = "\(title)"
achievementTitleLabel.zPosition = -9
addChild(achievementTitleLabel)
achievementTitleLabel.name = "AchievementTitleLabel"
achievementLabel = SKLabelNode(fontNamed: "Avenir-Black")
achievementLabel.fontColor = UIColor.black;
achievementLabel.fontSize = 13 //self.frame.maxY/30
achievementLabel.position = CGPoint (x: 0, y: -50)
achievementLabel.text = ("\(amount) / \(neededAmount)")
achievementLabel.zPosition = -9
addChild(achievementLabel)
achievementLabel.name = "AmountLabel"
}
func UpdateText() {
achievementLabel.text = ("\(amount) / \(neededAmount)")
}
func getAchievementProperties(){
switch achCounter {
case 0:
amount = 0;
neededAmount = 10;
incrementAmount = 100;
incrementAmount2 = 1000;
information = "No. Deaths"
title = "DAILY"
stage = 0
case 1:
amount = 0;
neededAmount = 5;
incrementAmount = 10;
incrementAmount2 = 70;
information = "No. Deaths"
title = "DAILY"
stage = 0
these are then put into a global array variable that is called “Achievements3” that is defined like so:
var Achievements3 = [SKNode]()
I am trying to get the achievements array to save when the game is “switched off” and when it is switched back on for it to replace the new nodes it generates in the AchievementMenu scene with the existing ones so that the data can be written over and the progress is still there. Along with this i am also trying to add one to the amount property of a certain achievement that is contained within the Array when something happens in the game scene such as the player dying for example. I can’t seem to find a way to access a specific element in an array and then add to its property it was given when it was generated from the sub class. I was going to use the NSUserdefaults to store all the SKNodes individually but It is too much just to store each individual achievement.
Can some please tell me what i’m doing wrong. if you would like to see my whole achievement menu scene it can be viewed below:
import Foundation
import SpriteKit
var Achievements3 = [SKNode]()
class AchievementMenu: SKScene {
//Array for Achievement Sprites
