Swift/Spritekit SKNode not detected on touch - swift

Question

I make a small game with swift and spritekit and I am currently working on the menu and made a custom Buttonclass called SKButtonNode as a Button which is a subclass of SKNode. When I click on the Button on my phone nothing happens though, even when I use "userInteractionEnabled = true". So why can't I see a "test2" when I touch a button but only see it if I hit next to a button?
class SKButtonNode: SKNode {
var defaultButton: SKSpriteNode
var activeButton: SKSpriteNode
var action: () -> Void
init(defaultButtonImage: String, activeButtonImage: String, buttonAction: () -> Void) {
defaultButton = SKSpriteNode(imageNamed: defaultButtonImage)
activeButton = SKSpriteNode(imageNamed: activeButtonImage)
activeButton.hidden = true
action = buttonAction
super.init()
userInteractionEnabled = true
addChild(defaultButton)
addChild(activeButton)
}
class MenuScene: SKScene, SKPhysicsContactDelegate {
var startGameButton: SKButtonNode!
var optionsGameButton: SKButtonNode!
var exitGameButton: SKButtonNode!
// Update time
var lastUpdateTimeInterval: NSTimeInterval = 0
override func didMoveToView(view: SKView) {
// Setup physics world's contact delegate
physicsWorld.contactDelegate = self
let startGameButton = SKButtonNode(defaultButtonImage: "blue_button_up", activeButtonImage: "blue_button_down" , buttonAction: startGame)
startGameButton.position = CGPoint(x: 640, y: 330)
startGameButton.activeButton.size = CGSize(width: 360, height: 95)
startGameButton.defaultButton.size = CGSize(width: 360, height: 95)
startGameButton.name = "startGameButton"
let startOptionsButton = SKButtonNode(defaultButtonImage: "blue_button_up", activeButtonImage: "blue_button_down" , buttonAction: startGame)
startOptionsButton.position = CGPoint(x: 640, y: 210)
startOptionsButton.activeButton.size = CGSize(width: 360, height: 95)
startOptionsButton.defaultButton.size = CGSize(width: 360, height: 95)
startOptionsButton.name = "startOptionsButton"
let exitGameButton = SKButtonNode(defaultButtonImage: "blue_button_up", activeButtonImage: "blue_button_down" , buttonAction: startGame)
exitGameButton.position = CGPoint(x: 640, y: 90)
exitGameButton.activeButton.size = CGSize(width: 360, height: 95)
exitGameButton.defaultButton.size = CGSize(width: 360, height: 95)
exitGameButton.name = "exitGameButton"
addChild(startGameButton)
addChild(startOptionsButton)
addChild(exitGameButton)
}
func exitGame() {
}
func startOptions(){
}
func startGame() {
print("test")
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
let location = touches.first!.locationInNode(self)
let node = self.nodeAtPoint(location)
print("test2")
if (node.name == "startGameButton") {
let currentNode = node as! SKButtonNode
currentNode.activeButton.hidden = false
currentNode.defaultButton.hidden = true
}
}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
let location = touches.first!.locationInNode(self)
let node = self.nodeAtPoint(location)
if (node.name == "startGameButton") {
let currentNode = node as! SKButtonNode
if currentNode.defaultButton.containsPoint(location) {
currentNode.activeButton.hidden = false
currentNode.defaultButton.hidden = true
} else {
currentNode.activeButton.hidden = true
currentNode.defaultButton.hidden = false
}
}
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
let location = touches.first!.locationInNode(self)
let node = self.nodeAtPoint(location)
print("test3")
if (node.name == "startGameButton") {
let currentNode = node as! SKButtonNode
if currentNode.defaultButton.containsPoint(location) {
startGame()
}
currentNode.activeButton.hidden = true
currentNode.defaultButton.hidden = false
}
}

Answer 1

It looks like you're never actually running your button's action. All you're doing when the button is pressed in touchesBegan is setting the .hidden property to true or false. Try something like this:
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
let location = touches.first!.locationInNode(self)
let node = self.nodeAtPoint(location)
print("test2")
if (node.name == "startGameButton") {
let currentNode = node as! SKButtonNode
self.runAction(currentNode.action)
currentNode.activeButton.hidden = false
currentNode.defaultButton.hidden = true
}
}
