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)
matchCardOne.position = CGPoint(x: -125, y: 60)
matchCardTwo.position = CGPoint(x: -125, y: -260)
matchCardThree.position = CGPoint(x: 70, y: 60)
matchCardFour.position = CGPoint(x: 70 , y: -260)
addChild(background)
addChild(matchCardOne)
addChild(matchCardTwo)
addChild(matchCardThree)
addChild(matchCardFour)
addChild(timerText)
}
override func touchesBegan(_ touches: Set, 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" {
let newTexture = SKTexture(imageNamed: "Apple")
FruitMatchCard1.init(texture: newTexture)
}
}
let touchTwo = touches.first
let positionInSceneTwo = touch!.location(in: self)
let touchedCardTwoNode =
self.atPoint(positionInScene) if let name = touchedCardTwoNode.name {
if name == "FruitMatchCard2" {
FruitMatchCard2.init(imageNamed: "Banana")
} }
let touchThree = touches.first let positionInSceneThree = touch!.location(in: self)
let touchedCardThreeNode = self.atPoint(positionInScene)
if let name = touchedCardThreeNode.name { if name == "FruitMatchCard3" { FruitMatchCard3.init(imageNamed: "Apple") } }
let touchFour = touches.first let positionInSceneFour = touch!.location(in: self)
let touchedCardFourNode = self.atPoint(positionInScene) if let name = touchedCardFourNode.name { if name == "FruitMatchCard4" { FruitMatchCard4.init(imageNamed: "Banana") } }
}
override func touchesEnded(_ touches: Set, 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!
