我的目标：访问SKnode数组中的元素及其在我的两个场景之间的属性，并保存并检索包含具有不同值的成就SKNode的数组。
所以我有两个场景，一个是我的实际游戏场景，第二个是我的成就菜单，其中包含我所有成就的列表。当achievementMenu场景开始时，它会产生27个成就，它们是SKNode的一个子类，叫做“成就”，见下文“
它是在这样的函数中制作的：
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)
}
这是包含所有成就的SKNode的子类属性：
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
然后将它们放入一个名为“Achievements3”的全局数组变量中，其定义如下：
var Achievements3 = [SKNode]()
我正在尝试获取成就数组，以便在游戏“关闭”时保存，并且当它重新打开时，它将替换在AchievementMenu场景中使用现有游戏生成的新节点，以便数据可以写下来，进展仍然存在。除此之外，我还尝试在游戏场景中发生某些事情（例如玩家死亡）时，在数组中包含的某个成就的数量属性中添加一个。我似乎无法找到一种方法来访问数组中的特定元素，然后添加到它的属性，它是从子类生成时给出的。我打算使用NSUserdefaults单独存储所有SKNodes，但存储每个单独的成就太多了。
有些人可以告诉我我做错了什么。如果你想看到我的整个成就菜单场景，可以在下面查看：
