Seque from a storyboard image tap into a SpriteKitScene - ios

Question

I'm creating a Swift project for a high school programming class. I can't seem to figure out this problem, and everyone else in my class doesn't seem to have any ideas.
To start, I created a new Swift project, and chose a game format.
I then used some basic code to make the first level for my game, a maze game where the maze moves around instead of the ball based on how the user tilts the device.
This is my GameScene.swift:
import SpriteKit
import CoreMotion
var accelupdateinterval = 0.1
var accelmultiplier = 15.0
class GameScene: SKScene {
let manager = CMMotionManager()
override func didMoveToView(view: SKView) {
manager.startAccelerometerUpdates()
manager.accelerometerUpdateInterval = accelupdateinterval
manager.startAccelerometerUpdatesToQueue(NSOperationQueue.mainQueue()){
(data, error) in
self.physicsWorld.gravity = CGVectorMake(CGFloat((data?.acceleration.x)!) * CGFloat(accelmultiplier), CGFloat((data?.acceleration.y)!) * CGFloat(accelmultiplier))
}
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
}
}
I want to have a main menu that the app opens into, which is mainMenu.storyboard:
I successfully have the app launching into the mainMenu.storyboard (and the level physics work well when I've tested the level1.sks), but I'm having trouble figuring out how to segue.
GOAL: I want people to be segued into the level1.sks (and the levels that I add later), when they tap the corresponding image in mainMenu.storyboard.
I can't use the method of adding a Storyboard Reference to segue it, as the Storyboard Reference won't let me choose level1.sks.
I'd also love to find out how to send users back to the main menu when the player icon touches the goal (the blue thing up near the top in this screenshot):

So to do this I think the best approach is to create another ViewController subclass, maybe named LauncherViewController, which will present your SKScene. Then in your storyboard add this viewController and have your menu segue to it on an image press.
Here is a start for the LauncherViewController
class LauncherViewController: UIViewController {
var gameScene: GameScene!
override func viewDidLoad() {
}
override func viewWillAppear() {
presentGameScene()
}
func presentGameScene(){
let skView = self.view as! SKView
skView.showsFPS = false
skView.showsNodeCount = false
skView.ignoresSiblingOrder = true
gameScene.size = skView.bounds.size
gameScene.scaleMode = .AspectFill
skView.presentScene(gameScene)
}
}
Where in your menu controller you have a prepareForSegue like this:
override func prepareForSegue(segue: UIStoryBoardSegue, sender: AnyObject?) {
if segue.identifier == "yourSegue" {
let destinationViewController = segue.destinationViewController as! LauncherViewController
destinationViewController.gameScene = GameScene()
}
to have your LauncherViewController dismiss the gameScene when the user finishes the maze, use a delegate pattern. So in GameScene add a protocol above your class
protocol GameDelegate {
func gameFinished()
}
have your LauncherViewController conform to this delegate and set the gameScene's delegate variable to self (see below)
class LauncherViewController: UIViewController, GameDelegate {
var gameScene: GameScene!
override func viewDidLoad() {
gameScene.delegate = self
}
override func viewWillAppear() {
presentGameScene()
}
func presentGameScene(){
let skView = self.view as! SKView
skView.showsFPS = false
skView.showsNodeCount = false
skView.ignoresSiblingOrder = true
gameScene.size = skView.bounds.size
gameScene.scaleMode = .AspectFill
skView.presentScene(gameScene)
}
func gameFinished(){
// this forces LauncherViewController to dismiss itself
dismissViewControllerAnimated(true, completion: nil)
}
}
add a variable in GameScene to hold the delegate (LauncherViewController) and add a function that calls the delegate function. You will also need to add the logic to know when the game is over as I haven't done that.
class GameScene: SKScene {
let manager = CMMotionManager()
var delegate: GameDelegate!
override func didMoveToView(view: SKView) {
manager.startAccelerometerUpdates()
manager.accelerometerUpdateInterval = accelupdateinterval
manager.startAccelerometerUpdatesToQueue(NSOperationQueue.mainQueue()){
(data, error) in
self.physicsWorld.gravity = CGVectorMake(CGFloat((data?.acceleration.x)!) * CGFloat(accelmultiplier), CGFloat((data?.acceleration.y)!) * CGFloat(accelmultiplier))
}
}
func gameOver(){
delegate.gameFinished()
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
// it's probably easiest to add the logic for a gameOver here
if gameIsOver {
gameOver()
}
}
}
There will probably be some mistakes in here as I wrote this on my phone so just comment below for anything you are unsure about or doesn't work.
