Main menu in Swift

Question

I would like to create a main menu for my game in the quick version.

I am using the following code:

import SpriteKit 

class menuScene: SKScene {

 //Adding Start Button let startButton = SKSpriteNode(imageNamed: "playButton") override func didMove(to view: SKView) { //Temporary Background backgroundColor = SKColor.darkGray //Start Button startButton.position = CGPoint(x: size.width / 2, y: size.height / 2) addChild(startButton) } override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { for touch in touches { let location = touch.location(in: self); //Finding location of touch if atPoint(location) == startButton { if let scene = GameScene(fileNamed: "GameScene") { scene.scaleMode = .aspectFill view!.presentScene(scene, transition: SKTransition.doorsOpenVertical(withDuration: 1)) } } } } 

}

When I run this, my application crashes and exits if atPoint (location) == startButton {. with "Thread 1, Breakpoint 1.1"

I'm not quite sure what it is, but I hope someone can help. Thanks!

Custom SKViews

Let's just say MWE , you need a menu, complexity and a game scene.

Then you can make a series of custom SKViews to jump between them.

Gameviewcontroller

This code loads menuScene:

 override func viewDidLoad() { super.viewDidLoad() let menuScene = MenuScene(size: view.bounds.size) let skView = view as! SKView skView.showsFPS = true skView.showsNodeCount = true skView.ignoresSiblingOrder = true menuScene.scaleMode = .resizeFill skView.presentScene(menuScene) } 

MenuScene

 class MenuScene: SKScene { let playButton = SKLabelNode() override init(size: CGSize) { super.init(size: size) backgroundColor = SKColor.white playButton.fontColor = SKColor.black playButton.text = "play" playButton.position = CGPoint(x: size.width / 2, y: size.height / 2) addChild(playButton) } required init(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) { let touch = touches.first let touchLocation = touch!.location(in: self) if playButton.contains(touchLocation) { let reveal = SKTransition.doorsOpenVertical(withDuration: 0.5) let difficultyScene = DifficultyScene(size: self.size) self.view?.presentScene(difficultyScene, transition: reveal) } } } 

Diffiffyscene

 class DifficultyScene: SKScene { let easyButton = SKLabelNode() let hardButton = SKLabelNode() let menuButton = SKLabelNode() override init(size: CGSize) { super.init(size: size) backgroundColor = SKColor.white easyButton.fontColor = SKColor.black easyButton.text = "easy" hardButton.fontColor = SKColor.black hardButton.text = "hard" menuButton.fontColor = SKColor.black menuButton.text = "menu" easyButton.position = CGPoint(x: size.width / 2, y: size.height / 2) hardButton.position = CGPoint(x: size.width / 2, y: size.height / 2 - easyButton.fontSize * 2) menuButton.position = CGPoint(x: size.width / 4 * 3, y: size.height / 4) addChild(easyButton) addChild(hardButton) addChild(menuButton) } required init(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") } override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) { let touch = touches.first let touchLocation = touch!.location(in: self) if easyButton.contains(touchLocation) { let reveal = SKTransition.doorsOpenVertical(withDuration: 0.5) let gameScene = GameScene(size: self.size, difficulty: easyButton.text!) self.view?.presentScene(gameScene, transition: reveal) } if hardButton.contains(touchLocation) { let reveal = SKTransition.doorsOpenVertical(withDuration: 0.5) let gameScene = GameScene(size: self.size, difficulty: hardButton.text!) self.view?.presentScene(gameScene, transition: reveal) } if menuButton.contains(touchLocation){ let reveal = SKTransition.doorsOpenVertical(withDuration: 0.5) let menuScene = MenuScene(size: self.size) self.view?.presentScene(menuScene, transition: reveal) } } } 

Gamescene

add this to your GameScene :

 init(size: CGSize, difficulty: String) { super.init(size: size) gameDifficulty = difficulty } required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") }

Storyboard

Alternatively, you can use storyboards. In MWE, for another SO question, they have a basic "menu".

In your case, what will you do:

• go to Main.storyboard.
• on the right hand toolbar, find the view controller
• drag-controller in Main.storyboard
• click new view controller
• click - on the right toolbar - identification inspector (looks like a business card)
• change class to GameViewController
• click on the view in the hierarchy on the left (under the new view controller)
• click inspector id
• change class to SKView
• click on the source view controller.
• click on identity inspector
• change class to UIViewController
• click on the view in the original UIViewController
• click on the identity inspector
• change class to UIView
• search button at the bottom of the right hand toolbar
• drag it to the first view
• right click drag from button to second view
• in the pop-up menu, under the action of segue, click show
• right-click with the up button, add horizontal center constraints.
• right-click drag from the button to the right, add vertical center constraints.
