SKScene當前場景轉換不能在Spift中使用SpriteKit場景

Question

我正在嘗試獲取帶有轉換行爲的SKScene presentScene。雖然我所得到的是默認的MoveUp轉換行爲，但本技術可行。我從場景的存檔加載SpriteKit場景。它似乎並不重要，我爲轉換類型放置什麼，我總是得到默認行爲。我已經調試過，以確保轉換有一個值（即不是零）。我正在使用iCloud和coreData管理對象，但我不知道這將如何影響場景演示。我在viewWillAppear中包含了託管對象代碼。

class GameViewController: UIViewController, GameDelegate { 
var managedObjectContext: NSManagedObjectContext! 
var heroCharacter : HeroCharacter! 

override func viewDidLoad() { 
    super.viewDidLoad() 

    presentGameScene() 
} 

override func viewWillAppear(animated: Bool) { 
    super.viewWillAppear(animated) 

    // access the application managed object context - jwg 
    managedObjectContext = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext 

    // Persistant Store Changes uses the coordinator 
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "receivePersistantStoreDidChange", name: NSPersistentStoreCoordinatorStoresDidChangeNotification, object: nil) 
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "receivePersistantStoreWillChange:", name: NSPersistentStoreCoordinatorStoresWillChangeNotification, object: managedObjectContext.persistentStoreCoordinator) 

    // iCloud notifications using the coordinator 
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "receiveICloudChanges:", name: NSPersistentStoreDidImportUbiquitousContentChangesNotification, object: managedObjectContext.persistentStoreCoordinator) 
} 

// MARK: scenes 
func presentGameScene() { 
    if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene { 

     // Configure the view. 
     let skView = self.view as! SKView 
     skView.showsFPS = true 
     skView.showsNodeCount = true 

     /* Sprite Kit applies additional optimizations to improve rendering performance */ 
     skView.ignoresSiblingOrder = true 

     /* Set the scale mode to scale to fit the window */ 
     scene.scaleMode = .AspectFill 

     // set target values 
     scene.heroCharacter = heroCharacter 
     scene.viewDelegate = self 

     // this transition is not working 
     let transition = SKTransition.fadeWithDuration(10) 
     skView.presentScene(scene, transition: transition) 
    } 
} 

現場代碼以及

override func didMoveToView(view: SKView) { 
    // access the application managed object context - jwg 
    managedObjectContext = (UIApplication.sharedApplication().delegate as! AppDelegate).managedObjectContext 

    // Setup physics world's contact delegate 
    physicsWorld.contactDelegate = self 

    // Setup waterfall 
    waterfall = self.childNodeWithName(kWaterfallName) as? SKSpriteNode 

    // Setup goal 
    goal = self.childNodeWithName("goal") as? SKSpriteNode 

    // Setup initial camera position 
    updateCamera() 

    // load texture atlases 
    CharacterSprite.loadTextureAtlasArrays() 

    var textureAtlasArray = [SKTextureAtlas]() 
    textureAtlasArray.append(SKTextureAtlas(named: kIcebergAtlas)) 

    SKTextureAtlas.preloadTextureAtlases(textureAtlasArray, withCompletionHandler: {() -> Void in 
     #if DEBUG 
      print("completed loading atlases") 
     #endif 
     self.startScene() 
    }) 
} 

func updateCamera() { 
    if let camera = camera { 
     camera.position = CGPoint(x: characterSprite!.position.x, y: characterSprite!.position.y) 
    } 
}

爲什麼你10秒的衰落相當通用的？似乎很長。這也是你的GameViewController中的代碼？

SKTransitions只有在從1個SKScene轉換到另一個SKScene時纔有效。從GameViewController加載第一個場景不會使用過渡，因爲技術上沒有任何變化。

作爲一個方面說明，在swift 2中，您可以擺脫擴展來取消存檔SKScene。你也可以說（如果你使用GameScene.sks）

if let scene = GameScene(fileNamed: "GameScene") { 
... 
}
