scope from class root, to inside init, to then inside touchesBegan? - swift

Question

Inside this, I'm not seeing goesTo getting assigned to nextScene. I assume this is a scope problem, but don't know enough to resolve it:
//
import SpriteKit
class MenuButton: SKLabelNode {
var goesTo: SKScene?
override init() {
super.init()
print("test... did this get called? WTF? HOW/WHY/WHERE?")
}
convenience init(text: String, color: SKColor, destination: SKScene){
self.init()
self.text = text
self.fontColor = color
goesTo = destination
self.isUserInteractionEnabled = true
print("gooing tooooo....", text, goesTo!) // WORKS!!!
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
if let nextScene = goesTo {
self.scene?.view?.presentScene(nextScene, transition: SKTransition.doorsOpenVertical(withDuration: 0.25))
print("going to", nextScene) // This is NIL! SO NEVER GETS CALLED!
}
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}

You code is correct, you can simply test it making for example a:
GameScene.swift
import SpriteKit
class GameScene: SKScene {
override func didMove(to view: SKView) {
print("- \(type(of:self))")
let helloScene = HelloScene.init()
helloScene.name = "helloScene"
let button1 = MenuButton.init(text: "HELLO", color: .red, destination: helloScene)
addChild(button1)
button1.position = CGPoint(x:self.frame.midX,y:self.frame.midY)
}
}
and you will see a red label in the middle of the screen with "HELLO".
As you can see also your prints looks good for both of your methods.
HelloScene.swift
import Foundation
import SpriteKit
class HelloScene: SKScene {
override func didMove(to view: SKView) {
print("- \(type(of:self))")
self.backgroundColor = .blue
}
}
