I am trying to make a RPG game in IOS, with a similar dialogue system in Baldurs Gate. I have created two arrays in a plist file. Like this:
As you can see I have two arrays: PlayerMessage; a list (it will be) of multiple choices that the player can touch and NPCMessages; the text that is displayed when the PlayerMessage is touched
I am at the stage where I can touch on the NPC and it will display a black box (NPCMessageer node) with text from the array (PlayerMessage via the plist file).
However, I don't know how to connect Item 0 in PlayerMessage and NPC Message and if they exist change the Message: SKLabelNode! text to one in NPCMessage. Does anyone know how to compare if another item exist in another array?
Here is the code that I have used:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?)
{
for touch in (touches) {
NPC.name = "NPC"
let Location = touch.location(in: self)
var CorrectedLocation = CGPoint()
CorrectedLocation.x = Location.x - LocalCamera.position.x
CorrectedLocation.y = Location.y - LocalCamera.position.y
let node = self.atPoint(CorrectedLocation)
var Message: SKLabelNode!
Message = SKLabelNode(fontNamed: "Trebuchet MS")
if (node.name == "NPC") {
let NPCMessageer = SKSpriteNode (color: UIColor.black, size: CGSize(width:1000, height:1000))
NPCMessageer.zPosition = 99
NPCMessageer.position = CGPoint(x:-500, y:-200)
Message.fontSize = 50
Message.color = UIColor.white; Message.position = CGPoint(x:-500, y:-100)
Message.zPosition = 100
addChild(NPCMessageer)
self.addChild(Message)
for PlayerMessage in NPC.PlayerMessage {
Message.text = PlayerMessage as?String}
let label = self.atPoint(CorrectedLocation)
if label.name == "Message"
{
if NPC.PlayerMessage == NPC.NPCMessage
{
Message.text = NPC.NPCMessage as?String
}
If I understand correctly you want to find a given element from one array in another array.
You can then use firstIdex(of:) and if an element exist use the returned index to set the Message object
let item = PlayerMessage[0] //assuming this is what you want to find
if let index = NPCMessage.firstIndex(of: item) {
let Message.text = NPCMessage[index]
}

I am creating an iOS AR app that sets text in a specific location and leaves it there for others to view. Is there a better way to implement it than what I am doing?
Currently, I have it set so that the text is saved to Firebase and loads it by setting the nodes relative to the camera’s position. I’m wondering if there is a way to save ARAnchors in a fashion similar to what I am doing but is that possible?
My current function for saving the text to the location via a user tapping the screen:
/*
* Variables for saving the user touch
*/
var touchX : Float = 0.0
var touchY : Float = 0.0
var touchZ : Float = 0.0
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
// will be used for getting the text
let textNode = SCNNode()
var writing = SCNText()
// gets the user’s touch upon tapping the screen
guard let touch = touches.first else {return}
let result = sceneView.hitTest(touch.location(in: sceneView), types: [ARHitTestResult.ResultType.featurePoint])
guard let hitResult = result.last else {return}
let hitTransform = SCNMatrix4.init(hitResult.worldTransform)
let hitVector = SCNVector3Make(hitTransform.m41, hitTransform.m42, hitTransform.m43)
// saves X, Y, and Z coordinates of touch relative to the camera
touchX = hitTransform.m41
touchY = hitTransform.m42
touchZ = hitTransform.m43
// Was thinking of adding the ability to change colors. Probably can skip next seven lines
var colorArray = [UIColor]()
colorArray.append(UIColor.red)
writing = SCNText(string: input.text, extrusionDepth: 1)
material.diffuse.contents = colorArray[0]
writing.materials = [material]
// modifies the node’s position and size
textNode.scale = SCNVector3(0.01, 0.01, 0.01)
textNode.geometry = writing
textNode.position = hitVector
sceneView.scene.rootNode.addChildNode(textNode)
// last few lines save the info to Firebase
let values = ["X" : touchX, "Y" : touchY, "Z" : touchZ, "Text" : input.text!] as [String : Any]
let childKey = reference.child("Test").childByAutoId().key
if input.text != nil && input.text != "" {
let child = reference.child("Test").child(childKey!)
child.updateChildValues(values)
} else {
let child = reference.child("Test").child(childKey!)
child.updateChildValues(values)
} // if
} // override func
/*
* Similar to the previous function but used in next function
*/
func placeNode(x: Float, y: Float, z: Float, text: String) -> Void {
let textNode = SCNNode()
var writing = SCNText()
let hitVector = SCNVector3Make(x, y, z)
touchX = x
touchY = y
touchZ = z
var colorArray = [UIColor]()
colorArray.append(UIColor.red)
writing = SCNText(string: text, extrusionDepth: 1)
material.diffuse.contents = colorArray[0]
writing.materials = [material]
textNode.scale = SCNVector3(0.01, 0.01, 0.01)
textNode.geometry = writing
textNode.position = hitVector
sceneView.scene.rootNode.addChildNode(textNode)
} // func
/*
* This next function is used in my viewDidLoad to load the data
*/
func handleData() {
reference.child("Test").observeSingleEvent(of: .value, with: { (snapshot) in
if let result = snapshot.children.allObjects as? [DataSnapshot] {
for child in result {
let xCoord = Float(truncating: child.childSnapshot(forPath: "X").value as! NSNumber)
let yCoord = Float(truncating: child.childSnapshot(forPath: "Y").value as! NSNumber)
let zCoord = Float(truncating: child.childSnapshot(forPath: "Z").value as! NSNumber)
let inscription = child.childSnapshot(forPath: "Text").value
self.placeNode(x: xCoord , y: yCoord , z: zCoord , text: inscription as! String)
} // for
} // if
}) // reference
} // func
I have looked into a few things such as ARCore but that looks like it uses Objective-C. I’ve made this app in Swift and I am not sure if I can incorporate ARCore with how I have implemented my current application.
Do I just need to get over it and learn Objective-C? Can I still work with what I have?
I think that ARCore anchors are only available for 24 hours, so that could be a problem.
You probably need to use ARKit2.0's ARWorldMap and save it as data on firebase for others to see the text in the same place, otherwise you are assuming in your code that future users will start their AR session in the exact same position and direction as the person who left the text. You probably need to use core location first to see where in the world the user is.
I'm working on an app which lets users have randomized data when you shake your device.
I have 4 arrays to hold the string data and function which creates randomized number;
let characters = ["Zoolog", "Xander"]
let problems = ["Asteroid", "Dr Evil"]
let places = ["Vast Desert", "Ice Caves"]
let time = ["Wednesday 12th, 1220", "1236"]
func randomCharacter() -> String {
let randomNumber = GKRandomSource.sharedRandom().nextInt(upperBound: characters.count)
return characters[randomNumber]
}
func randomPlaces() -> String {
let randomNumberOne = GKRandomSource.sharedRandom().nextInt(upperBound: places.count)
return places[randomNumberOne]
}
func randomProblems() -> String {
let randomNumberTwo = GKRandomSource.sharedRandom().nextInt(upperBound: problems.count)
return problems[randomNumberTwo]
}
func randomTime() -> String {
let randomNumberThree = GKRandomSource.sharedRandom().nextInt(upperBound: time.count)
return time[randomNumberThree]
}
On my viewController, data is randomized and users get a randomized data on their screen once they shake their devices.
override func motionEnded(_ motion: UIEventSubtype, with event: UIEvent?) {
if(event?.subtype == UIEventSubtype.motionShake) {
characterName.text = myStoryCharacters.randomCharacter()
placeName.text = myStoryCharacters.randomPlaces()
problemName.text = myStoryCharacters.randomProblems()
timeName.text = myStoryCharacters.randomTime()
}
}
I also have an imageView for the character picture. So once the data is randomized I would like my users to see the characters and their names as well. But at the moment, I can only randomize the imageView and characters separately not together.
I've gone through some sample codes but couldn't understand how to approach this.
--Updated
Note: I don't have a problem with the code I have. I don't know how to randomize the characterImageView to match with the characterName. So if a picture belongs to a character in my character array then the nameLabel and imageView should match.
override func viewDidLoad() {
super.viewDidLoad()
super.becomeFirstResponder()
// Do any additional setup after loading the view, typically from a nib.
characterImageView.image = UIImage(named: "elegantEmma")
placeImageView.image = UIImage(named: "zombieLand")
problemImageView.image = UIImage(named: "meteor")
timeImageView.image = UIImage(named: "time")
//First random value shown on the launch
characterName.text = myStoryCharacters.randomCharacter()
placeName.text = myStoryCharacters.randomPlaces()
problemName.text = myStoryCharacters.randomProblems()
timeName.text = myStoryCharacters.randomTime()
You need to store the image names in arrays as well, so for example for your characters have...
let characters = ["Zoolog", "Xander"]
let characterImages = ["ZoologImage", "XanderImage"] // These relate to the image names in your assets
func randomCharacter() -> String {
let randomNumber = GKRandomSource.sharedRandom().nextInt(upperBound: characters.count)
characterImageView.image = UIImage(named: characterImages[randomNumber])
return characters[randomNumber]
}
Then do the same for the other arrays, you could also change the random functions to set the text and not bother returning it, unless of course you need it for something else
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'm using the scene editor in SpriteKit to place color sprites and assign them textures using the Attributes Inspector. My problem is trying to figure out how to reference those sprites from my GameScene file. For example, I'd like to know when a sprite is a certain distance from my main character.
Edit - code added
I'm adding the code because for some reason, appzYourLife's answer worked great in a simple test project, but not in my code. I was able to use Ron Myschuk's answer which I also included in the code below for reference. (Though, as I look at it now I think the array of tuples was overkill on my part.) As you can see, I have a Satellite class with some simple animations. There's a LevelManager class that replaces the nodes from the scene editor with the correct objects. And finally, everything gets added to the world node in GameScene.swift.
Satellite Class
func spawn(parentNode:SKNode, position: CGPoint, size: CGSize = CGSize(width: 50, height: 50)) {
parentNode.addChild(self)
createAnimations()
self.size = size
self.position = position
self.name = "satellite"
self.runAction(satAnimation)
self.physicsBody = SKPhysicsBody(circleOfRadius: size.width / 2)
self.physicsBody?.affectedByGravity = false
self.physicsBody?.categoryBitMask = PhysicsCategory.satellite.rawValue
self.physicsBody?.contactTestBitMask = PhysicsCategory.laser.rawValue
self.physicsBody?.collisionBitMask = 0
}
func createAnimations() {
let flyFrames:[SKTexture] = [textureAtlas.textureNamed("sat1.png"),
textureAtlas.textureNamed("sat2.png")]
let flyAction = SKAction.animateWithTextures(flyFrames, timePerFrame: 0.14)
satAnimation = SKAction.repeatActionForever(flyAction)
let warningFrames:[SKTexture] = [textureAtlas.textureNamed("sat8.png"),
textureAtlas.textureNamed("sat1.png")]
let warningAction = SKAction.animateWithTextures(warningFrames, timePerFrame: 0.14)
warningAnimation = SKAction.repeatActionForever(warningAction)
}
func warning() {
self.runAction(warningAnimation)
}
Level Manager Class
import SpriteKit
class LevelManager
{
let levelNames:[String] = ["Level1"]
var levels:[SKNode] = []
init()
{
for levelFileName in levelNames {
let level = SKNode()
if let levelScene = SKScene(fileNamed: levelFileName) {
for node in levelScene.children {
switch node.name! {
case "satellite":
let satellite = Satellite()
satellite.spawn(level, position: node.position)
default: print("Name error: \(node.name)")
}
}
}
levels.append(level)
}
}
func addLevelsToWorld(world: SKNode)
{
for index in 0...levels.count - 1 {
levels[index].position = CGPoint(x: -2000, y: index * 1000)
world.addChild(levels[index])
}
}
}
GameScene.swift - didMoveToView
world = SKNode()
world.name = "world"
addChild(world)
physicsWorld.contactDelegate = self
levelManager.addLevelsToWorld(self.world)
levelManager.levels[0].position = CGPoint(x:0, y: 0)
//This does not find the satellite nodes
let satellites = children.flatMap { $0 as? Satellite }
//This does work
self.enumerateChildNodesWithName("//*") {
node, stop in
if (node.name == "satellite") {
self.satTuple.0 = node.position
self.satTuple.1 = (node as? SKSpriteNode)!
self.currentSatellite.append(self.satTuple)
}
}
The Obstacle class
First of all you should create an Obstacle class like this.
class Obstacle: SKSpriteNode { }
Now into the scene editor associate the Obstacle class to your obstacles images
The Player class
Do the same for Player, create a class
class Player: SKSpriteNode { }
and associate it to your player sprite.
Checking for collisions
Now into GameScene.swift change the updated method like this
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
let obstacles = children.flatMap { $0 as? Obstacle }
let player = childNodeWithName("player") as! Player
let obstacleNearSprite = obstacles.contains { (obstacle) -> Bool in
let distance = hypotf(Float(player.position.x) - Float(obstacle.position.x), Float(player.position.y) - Float(obstacle.position.y))
return distance < 100
}
if obstacleNearSprite {
print("Oh boy!")
}
}
What does it do?
The first line retrieves all your obstacles into the scene.
the second line retrieves the player (and does crash if it's not present).
Next it put into the obstacleNearSprite constant the true value if there is at least one Obstacle at no more then 100 points from Player.
And finally use the obstacleNearSprite to print something.
Optimizations
The updated method gets called 60 times per second. We put these 2 lines into it
let obstacles = children.flatMap { $0 as? Obstacle }
let player = childNodeWithName("player") as! Player
in order to retrieves the sprites we need. With the modern hardware it is not a problem but you should save references to Obstacle and Player instead then searching for them in every frame.
Build a nice game ;)
you will have to loop through the children of the scene and assign them to local objects to use in your code
assuming your objects in your SKS file were named Obstacle1, Obstacle2, Obstacle3
Once in local objects you can check and do whatever you want with them
let obstacle1 = SKSpriteNode()
let obstacle2 = SKSpriteNode()
let obstacle3 = SKSpriteNode()
let obstacle3Location = CGPointZero
func setUpScene() {
self.enumerateChildNodesWithName("//*") {
node, stop in
if (node.name == "Obstacle1") {
self.obstacle1 = node
}
else if (node.name == "Obstacle2") {
self.obstacle2 = node
}
else if (node.name == "Obstacle3") {
self.obstacle3Location = node.position
}
}
}
I have these two UITextFields and the first texField subtracts the number from the second textField. It then takes the answer and puts it in my SKLabelNode. That works fine. But the problem Im having is that it doesn't save the label. When I quit the app and go back to it it doesnt save the value. What am I doing wrong with my code?
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
for touch in (touches as! Set<UITouch>) {
var defaults=NSUserDefaults.standardUserDefaults()
var save=defaults.integerForKey("saveCalories")
var touch: UITouch = touches.first as! UITouch
var location = touch.locationInNode(self)
var node = self.nodeAtPoint(location)
if let number1 = textFieldCaloriesIntake.text.toInt() {
if let number2 = textFieldCaloriesBurned.text.toInt() {
let subtract = number1 - number2
defaults.setInteger(subtract, forKey: "saveCalories")
var showTotalCalories = defaults.integerForKey("saveCalories")
totalCaloriesLabel.text = String(showTotalCalories)
NSUserDefaults.standardUserDefaults().synchronize()
}
}
}
}
Use this code for Swift
NSUserDefaults.standardUserDefaults().setValue(value, forKey:key)
Save example:
NSUserDefaults.standardUserDefaults().setValue(positionTextField.text!, forKey: "position")
Retrieve example:-
position!.text=NSUserDefaults.standardUserDefaults().stringForKey("position")
Note: remember the key for further retrievals
Save the text of the label in NSUserDefaultinstead
I got it to work by putting the code in the didMoveToView; it saves the label now.
