Im trying to keep track of how many times the user loses in my game. So for every loss it goes up by 1. I also want to save it too so the user could see how many total times they lost. Right now the code I have it works the first time and goes to one but if I lose in the game after that it just stays at 1. What am I doing wrong? Thanks!
class level1: SKScene, SKPhysicsContactDelegate, GKGameCenterControllerDelegate {
var deathScore = 0
override func didMoveToView(view: SKView) {
var deathLabel = SKLabelNode()
deathLabel = SKLabelNode(fontNamed: "LadyIce-3D")
deathLabel.text = "100"
deathLabel.zPosition = 14
deathLabel.fontSize = 100
deathLabel.fontColor = SKColor.darkTextColor()
deathLabel.position = CGPointMake(self.size.width / 1.1, self.size.height / 1.4)
deathLabel.hidden = true
self.addChild(deathLabel)
}
if firstBody.categoryBitMask == HeroCategory && fourthBody.categoryBitMask == GameOverCategory {
deathScore++
deathLabel.hidden = false
let defaults = NSUserDefaults()
let saveDeaths = NSUserDefaults().integerForKey("saveNumberOfDeaths")
if(deathScore > saveDeaths)
{
NSUserDefaults().setInteger(saveDeaths, forKey: "saveNumberOfDeaths")
}
var showNumberOfDeaths = defaults.integerForKey("saveNumberOfDeaths")
deathLabel.text = String(showNumberOfDeaths)
}
}
You are declaring a new var deathScore everytime, initialized with 0 and incrementing it. It will always be 1.
UserDefaults.standard.set(UserDefaults.standard.integer(forKey: "saveNumberOfDeaths")+1, forKey: "saveNumberOfDeaths")
deathLabel.text = String(UserDefaults.standard.integer(forKey: "saveNumberOfDeaths"))

I am looking for some advice when it comes to saving a score in my app - I currently have a coin count working in which through my HUD class when I collide through Coins the value increases accordingly. My next step is trying to initiate a high-score that initiates, after some research I think the topic I am looking into is based around NSUserDefaults..
The current code :
import SpriteKit
class HUD: SKNode {
//An SKLabelNode to print the coin score:
let coinCountText = SKLabelNode(text: "000000")
func createHUDNodes(){
// Configure the coin text label:
coinCountText.fontName = "STHupo-Heavy-Italic"
let coinTextPosition = CGPoint(x: -cameraOrigin.x + 770, y: coinPosition.y)
coinCountText.position = coinTextPosition
coinCountText.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.left
coinCountText.verticalAlignmentMode = SKLabelVerticalAlignmentMode.center
// Add the text label and coin icon to the HUD:
self.addChild(coinCountText)
}
func setCoinCountDisplay(newCoinCount:Int) {
let formatter = NumberFormatter()
let number = NSNumber(value: newCoinCount)
formatter.minimumIntegerDigits = 6
if let coinStr =
formatter.string(from: number) {
// Update the label node with the new count:
coinCountText.text = coinStr
}
}
Working in the HUD class I think naturally I would need to create another 'SKlabelNode'for the highscore node which I can duplicate from the code that works above.. my problem is how can I implement a highscore feature in the app, as when closed and re-opening the application it will remember the highscore..
I assume the following code would need to be added but I do not understand how it ties together in the class.
var currentHighScore =
NSUserDefaults.standardUserDefaults().integerForKey("coin_highscore")
var highScoreLabel = SKLabelNode(fontNamed:"STHupo-Heavy-Italic")
highScoreLabel.text = ""
highScoreLabel.fontSize = 45
highScoreLabel.position = CGPoint(x: viewSize.width * 0.5, y: viewSize.height * 0.30)
self.addChild(highScoreLabel)
if (score > currentHighScore) {
NSUserDefaults.standardUserDefaults().setInteger(score, forKey: "player_highscore")
NSUserDefaults.standardUserDefaults().synchronize()
highScoreLabel.text = "New High Score: \(score) !"
} else {
highScoreLabel.text = "Better Luck Next Time: \(score)"
}
}
Any advice on how I could integrate this code would be much appreciated.

Revised :
else if nodeTouched.name == "returnToMenu"{
// Transition to the main menu scene
self.view?.presentScene(MenuScene(size: self.size),transition.crossFade(withDuration: 0.6))
let currentHighScore = UserDefaults.standard.integer(forKey: "Player_highscore")
let highScoreLabel = SKLabelNode(fontNamed:"STHupo-Heavy-Italic")
highScoreLabel.text = "Value: \ (String(describing: coin.value))"
highScoreLabel.text = ""
highScoreLabel.fontSize = 45
highScoreLabel.zPosition = 100
highScoreLabel.position = CGPoint(x: 50, y: 50)
self.addChild(highScoreLabel)
if (coin.value > currentHighScore) {
UserDefaults.standard.set(coin.value, forKey: "Player_highscore")
UserDefaults.standard.synchronize()
highScoreLabel.text = "New High Value: \(String(describing: coin.value)) !"
} else {
highScoreLabel.text = "Better Luck Next Time: \(String(describing: coin.value))"
}
}
}
}
I am assuming it's the referencing to my original HUD that is causing the problem? In my coin class I declared the coin.value = 5, each time the coin is collected by coinCountDisplay increases accordingly. However still does not show - :/
Add a property to your view controller with both get and set and use it in all the places. The get method should get the value from UserDefaults and the set should update the value in UserDefaults.
var coinHighscore: Int {
get {
UserDefaults.standard.integer(forKey: "coin_highscore")
}
set {
UserDefaults.standard.set(newValue, forKey: "coin_highscore")
}
}
Extending on Frankenstein's answer, IF you want to use Swift 5 you can use Property Wrappers to avoid writing get and set every time:
#propertyWrapper struct UserDefaultsBacked<Value> {
let key: String
let defaultValue: Value
var storage: UserDefaults = .standard
var wrappedValue: Value {
get {
let value = storage.value(forKey: key) as? Value
return value ?? defaultValue
}
set {
storage.setValue(newValue, forKey: key)
}
}
}
And use it like this:
#UserDefaultsBacked(key: "coin_highscore", defaultValue: 0)
var coinHighscore: Int
I am trying to detect if one of the nodes that I have made through a subclass of SKNode (called Achievements) exists and if it doesn't exist then i'm trying to turn off a boolean variable.
What I use to locate the SKShapeNode (called "Indicator")
func checkIndicatorStatus() {
moveableArea.enumerateChildNodes(withName: "Achievement") {
(node, stop) in
let Indicate = node
Indicate.enumerateChildNodes(withName: "Indicator") {
node, stop in
if let Achievement = node as? Achievements {
menuAchieveNotificationOn = false
}
}
}
}
I have enumerated through the nodes specifically and tried searching for it but it doesn't seem to do anything. what am I doing wrong?
Here is my subclass. I have many of them named achievement displayed in my scene.
class Achievements: SKNode {
//Nodes used throughout the SKNode class
var achievementLabel = SKLabelNode()
var achievementTitleLabel = SKLabelNode()
var achievementNode = SKSpriteNode()
var notifyCircle = SKShapeNode()
//Amount Variables used as Achievement Properties
var image: String = ""
var information: String = ""
var title: String = ""
var amount = 0
var neededAmount = 0
var notification:Bool = false
var stage = 0
func getachievementData(AchName: String) {
let getDataRequest:NSFetchRequest<Achievement> = Achievement.fetchRequest()
getDataRequest.predicate = NSPredicate(format: "theSearchName == %#" , AchName)
do {
let searchResults = try CoreDatabaseContoller.getContext().fetch(getDataRequest)
//print("number of results: \(searchResults.count)")
for result in searchResults as [Achievement] {
title = result.theName!
information = result.theDescription!
image = result.theImage!
amount = Int(result.aAmount!)
neededAmount = Int(result.aNeededAmount!)
stage = Int(result.aStage!)
if result.aHasBeenAchieved!.intValue == 1 {
notification = true
}
}
}
catch {
print("ERROR: \(error)")
}
createAchievement()
}
func createAchievement() {
let tex:SKTexture = SKTexture(imageNamed: image)
achievementNode = SKSpriteNode(texture: tex, color: SKColor.black, size: CGSize(width: 85, height: 85)) //frame.maxX / 20, height: frame.maxY / 20))
achievementNode.zPosition = -10
achievementSprites.append(achievementNode)
self.name = "Achievement"
self.addChild(achievementNode)
self.zPosition = -11
createAchievementLabels()
}
func createAchievementLabels() {
achievementTitleLabel = SKLabelNode(fontNamed: "Avenir-Black")
achievementTitleLabel.fontColor = UIColor.black;
achievementTitleLabel.fontSize = 15 //self.frame.maxY/30
achievementTitleLabel.position = CGPoint (x: 0, y: 50)
achievementTitleLabel.text = "\(title)"
achievementTitleLabel.zPosition = -9
addChild(achievementTitleLabel)
achievementLabel = SKLabelNode(fontNamed: "Avenir-Black")
achievementLabel.fontColor = UIColor.black;
achievementLabel.fontSize = 13 //self.frame.maxY/30
achievementLabel.position = CGPoint (x: 0, y: -55)
achievementLabel.text = ("\(amount) / \(neededAmount)")
achievementLabel.zPosition = -9
addChild(achievementLabel)
if notification == true {
notifyCircle = SKShapeNode(circleOfRadius: 10)
notifyCircle.fillColor = .red
notifyCircle.position = CGPoint(x: 30 , y: 35)
notifyCircle.zPosition = 1000
notifyCircle.name = "Indicator"
addChild(notifyCircle)
}
}
}
EDIT 1
As you can see from the image below, there are a number of different achievement nodes each with their individual names and unlock criteria, when an achievement becomes unlocked it makes an indicator and changes the graphic, which is seen for the two X nodes here with the coloured red circle in the top right corners of each of them which is the "indicator" (if you look at the subclass at the bottom of it the creation of the indicator is there)
Now as you can seen the big red button in the bottom right hand corner of the picture is the achievement menu button which also has an indicator which is controlled by the bool variable (menuAchieveNotificationOn) what i'm trying to achieve is once the achievements with the indicators have each been pressed they are removed from the node.
what i'm trying to do is search each of the nodes to see if the indicator still exists if not I want to turn the variable (menuAchieveNotificationOn) to false.
You should be able to use this:
if let indicatorNode = childNode(withName: "//Indicator") as! SKShapeNode? {
menuAchieveNotificationOn = false
} else {
menuAchieveNotificationOn = true
}
EDIT: to run some code for EVERY "indicator" node in the scene. If any are found, achievementsFound is set to true:
achievementsFound = false
enumerateChildNodes(withName: "//Indicator") { indicatorNode, _ in
// Do something with indicatorNode
achievementsFound = true
}
Although this seems too simple, so I might have misunderstood your aim.
I have a class that creates variables for multiple SpriteNods which looks like this:
class Enemy {
var speed:Float = 0.0
var guy:SKSpriteNode
var currentFrame = 0
var randomFrame = 0
var moving = false
var rotationSpeed:CGFloat = 1.0
var angle = 0.0
var range = 1.2
var yPos = CGFloat()
var rotationDirection:Int = 0
var preLocation:CGFloat = 0
var health:Int = 0
init(speed:Float, guy:SKSpriteNode, rotationSpeed:CGFloat, rotationDirection:Int, preLocation:CGFloat, health:Int) {
self.speed = speed
self.guy = guy
self.rotationSpeed = rotationSpeed
self.rotationDirection = rotationDirection
self.preLocation = preLocation
self.health = health
}
A SpriteNode is then applied to the Enemy like this:
func addEnemy(#named: String, speed:Float, yPos: CGFloat, rotationSpeed:CGFloat, rotationDirection:Int, preLocation:CGFloat, health:Int) {
var enemyNode = SKSpriteNode(imageNamed: named)
enemyNode.physicsBody = SKPhysicsBody(texture: enemyNode.texture, alphaThreshold: 0, size: enemyNode.size)
enemyNode.physicsBody!.affectedByGravity = false
enemyNode.physicsBody!.categoryBitMask = ColliderType.Enemy.rawValue
enemyNode.physicsBody!.contactTestBitMask = ColliderType.Hero.rawValue | ColliderType.Enemy.rawValue
enemyNode.physicsBody!.collisionBitMask = ColliderType.Hero.rawValue | ColliderType.Enemy.rawValue
enemyNode.physicsBody?.allowsRotation = false
var enemy = Enemy(speed: speed, guy: enemyNode, rotationSpeed: rotationSpeed, rotationDirection: rotationDirection, preLocation: preLocation, health: health)
enemys.append(enemy)
enemy.guy.name = named
resetEnemy(enemyNode, yPos: yPos)
enemy.yPos = enemyNode.position.y
addChild(enemyNode)
}
Now i have the problem that in the didBeginContact function i only get the SpriteNodes back so i can't get to the enemy specific variables, like health.
So i want to know how i can reference the enemy class to the spritenode, so i can use it in the didBeginContact function.
I hope someone can help me. Thanks.
I just ran into this exact problem. You need to cast the node as the object you are looking for. In didBeginContact it would be something like this:
if let myEnemy = contact.bodyA.node as? Enemy {
myEnemy.speed = 99
}
I have been working on my xcode project for a couple of weeks now using Xcode and swift. Today when I started running the simulator my highScore was set to 0. This was the first time, it had always kept score. Does this have anything to do with the simulator or is something wrong with my code. I of course don't want the user to use my app if the highScore can reset to 0 at any given time.
class GameScene: SKScene {
let labelHighScore = SKLabelNode()
var highScore = 0
override func didMoveToView(view: SKView) {
var HighscoreDefault = NSUserDefaults.standardUserDefaults()
if(HighscoreDefault.valueForKey("Highscore") != nil) {
highScore = HighscoreDefault.valueForKey("Highscore") as! NSInteger
labelHighScore.text = NSString(format: "%i", highScore) as String
}
labelHighScore.fontSize = 70
labelHighScore.position = CGPointMake(frame.midX, frame.midY + 305)
labelHighScore.fontColor = UIColor.blackColor()
self.addChild(labelHighScore)
}
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
if ball != blackB && ball.texture == blackB.texture {
score += 1
labelScore.text = String(score)
if(score > highScore) {
highScore = score
labelHighScore.text = String(highScore)
var HighscoreDefault = NSUserDefaults.standardUserDefaults()
HighscoreDefault.setValue(highScore, forKey: "Highscore")
HighscoreDefault.synchronize()
}
}
Unless your using the same device it would not keep the same user defaults. If you have always used the simulator they are known to reset from time to time. My suggestions would be to explicitly set the high score's default and run. comment out the code that sets the default and re run. It should maintain that value.
How can I create a timer that fires every two seconds that will increment the score by one on a HUD I have on my screen? This is the code I have for the HUD:
#implementation MyScene
{
int counter;
BOOL updateLabel;
SKLabelNode *counterLabel;
}
-(id)initWithSize:(CGSize)size
{
if (self = [super initWithSize:size])
{
counter = 0;
updateLabel = false;
counterLabel = [SKLabelNode labelNodeWithFontNamed:#"Chalkduster"];
counterLabel.name = #"myCounterLabel";
counterLabel.text = #"0";
counterLabel.fontSize = 20;
counterLabel.fontColor = [SKColor yellowColor];
counterLabel.horizontalAlignmentMode = SKLabelHorizontalAlignmentModeCenter;
counterLabel.verticalAlignmentMode = SKLabelVerticalAlignmentModeBottom;
counterLabel.position = CGPointMake(50,50); // change x,y to location you want
counterLabel.zPosition = 900;
[self addChild: counterLabel];
}
}
In Sprite Kit do not use NSTimer, performSelector:afterDelay: or Grand Central Dispatch (GCD, ie any dispatch_... method) because these timing methods ignore a node's, scene's or the view's paused state. Moreover you do not know at which point in the game loop they are executed which can cause a variety of issues depending on what your code actually does.
The only two sanctioned ways to perform something time-based in Sprite Kit is to either use the SKScene update: method and using the passed-in currentTime parameter to keep track of time.
Or more commonly you would just use an action sequence that starts with a wait action:
id wait = [SKAction waitForDuration:2.5];
id run = [SKAction runBlock:^{
// your code here ...
}];
[node runAction:[SKAction sequence:#[wait, run]]];
And to run the code repeatedly:
[node runAction:[SKAction repeatActionForever:[SKAction sequence:#[wait, run]]]];
Alternatively you can also use performSelector:onTarget: instead of runBlock: or perhaps use a customActionWithDuration:actionBlock: if you need to mimick the SKScene update: method and don't know how to forward it to the node or where forwarding would be inconvenient.
See SKAction reference for details.
UPDATE: Code examples using Swift
Swift 5
run(SKAction.repeatForever(SKAction.sequence([
SKAction.run( /*code block or a func name to call*/ ),
SKAction.wait(forDuration: 2.5)
])))
Swift 3
let wait = SKAction.wait(forDuration:2.5)
let action = SKAction.run {
// your code here ...
}
run(SKAction.sequence([wait,action]))
Swift 2
let wait = SKAction.waitForDuration(2.5)
let run = SKAction.runBlock {
// your code here ...
}
runAction(SKAction.sequence([wait, run]))
And to run the code repeatedly:
runAction(SKAction.repeatActionForever(SKAction.sequence([wait, run])))
In Swift usable:
var timescore = Int()
var actionwait = SKAction.waitForDuration(0.5)
var timesecond = Int()
var actionrun = SKAction.runBlock({
timescore++
timesecond++
if timesecond == 60 {timesecond = 0}
scoreLabel.text = "Score Time: \(timescore/60):\(timesecond)"
})
scoreLabel.runAction(SKAction.repeatActionForever(SKAction.sequence([actionwait,actionrun])))
I've taken the swift example above and added in leading zeros for the clock.
func updateClock() {
var leadingZero = ""
var leadingZeroMin = ""
var timeMin = Int()
var actionwait = SKAction.waitForDuration(1.0)
var timesecond = Int()
var actionrun = SKAction.runBlock({
timeMin++
timesecond++
if timesecond == 60 {timesecond = 0}
if timeMin / 60 <= 9 { leadingZeroMin = "0" } else { leadingZeroMin = "" }
if timesecond <= 9 { leadingZero = "0" } else { leadingZero = "" }
self.flyTimeText.text = "Flight Time [ \(leadingZeroMin)\(timeMin/60) : \(leadingZero)\(timesecond) ]"
})
self.flyTimeText.runAction(SKAction.repeatActionForever(SKAction.sequence([actionwait,actionrun])))
}
Here's the full code to build a timer for SpriteKit with Xcode 9.3 and Swift 4.1
In our example the score label will be incrementd by 1 every 2 seconds.
Here's final result
Good, let's start!
1) The score label
First of all we need a label
class GameScene: SKScene {
private let label = SKLabelNode(text: "Score: 0")
}
2) The score label goes into the scene
class GameScene: SKScene {
private let label = SKLabelNode(text: "Score: 0")
override func didMove(to view: SKView) {
self.label.fontSize = 60
self.addChild(label)
}
}
Now the label is at the center of the screen. Let's run the project to see it.
Please note that at this point the label is not being updated!
3) A counter
We also want to build a counter property which will hold the current value displayed by the label. We also want the label to be updated as soon as the counter property is changed so...
class GameScene: SKScene {
private let label = SKLabelNode(text: "Score: 0")
private var counter = 0 {
didSet {
self.label.text = "Score: \(self.counter)"
}
}
override func didMove(to view: SKView) {
self.label.fontSize = 60
self.addChild(label)
// let's test it!
self.counter = 123
}
}
4) The actions
Finally we want to build an action that every 2 seconds will increment counter
class GameScene: SKScene {
private let label = SKLabelNode(text: "Score: 0")
private var counter = 0 {
didSet {
self.label.text = "Score: \(self.counter)"
}
}
override func didMove(to view: SKView) {
self.label.fontSize = 60
self.addChild(label)
// 1 wait action
let wait2Seconds = SKAction.wait(forDuration: 2)
// 2 increment action
let incrementCounter = SKAction.run { [weak self] in
self?.counter += 1
}
// 3. wait + increment
let sequence = SKAction.sequence([wait2Seconds, incrementCounter])
// 4. (wait + increment) forever
let repeatForever = SKAction.repeatForever(sequence)
// run it!
self.run(repeatForever)
}
}
The following code creates a new thread and waits 2 seconds before doing something on the main thread:
BOOL continueIncrementingScore = YES;
dispatch_async(dispatch_queue_create("timer", NULL);, ^{
while(continueIncrementingScore) {
[NSThread sleepForTimeInterval:2];
dispatch_async(dispatch_get_main_queue(), ^{
// this is performed on the main thread - increment score here
});
}
});
Whenever you want to stop it - just set continueIncrementingScore to NO
