skscene

问题 I am creating a game in sprite kit using swift, and I am trying to be able to move the SKScene around with a finger because not all of the nodes fit within the scene. I have already created world, overlay, and camera nodes with this code. override func didMoveToView(view: SKView) { world = self.childNodeWithName("world")! if !isCreated { isCreated = true // Camera setup self.anchorPoint = CGPoint(x: 0.5, y: 0.5) self.world = SKNode() self.world.name = "world" addChild(self.world) self.cam =

问题 I'm trying to learn how to make a GameManager type class, and making individual classes for each of my GameScenes... probably the wrong thing to do, but for the sake of this question, please accept this as the way to do things. My GameManager looks like this, having a reference to each of the scenes, that's static: import SpriteKit class GM { static let scene2 = SecondScene() static let scene3 = ThirdScene() static let home = SKScene(fileNamed: "GameScene") } How do I create a SKScene

问题 As a followup to this question, I need to iterate over each .sks file in a folder, namely, "Levels". My project looks like this: Here's what I've written: let directory = NSFileManager.defaultManager().currentDirectoryPath let paths = NSBundle.mainBundle().pathsForResourcesOfType("sks", inDirectory: directory) let files = paths.map() { (path : AnyObject) -> String in return (path as String).lastPathComponent } println("Files\n\(files)") let firstLevel = files[0] if let scene = SKScene

问题 I'm relatively new to swift programming. I have made an app where I didn't use SpriteKit and I would size most views by scaling down the images to a multiple of the screens width and height. Not sure if this is the best tactic, but it worked and I was able to build an app that looked good on all devices. With spritekit and the scene.sks files, I don't have the option of auto-layouts to size my sprites like I did before. There isn't a lot of content about universal apps online, so I'm

问题 In my SpriteKit Game i'm using: self.scene!.removeFromParent() let skView = self.view! as SKView skView.ignoresSiblingOrder = true var scene: PlayScene! scene = PlayScene(size: skView.bounds.size) scene.scaleMode = .AspectFill skView.presentScene(scene, transition: SKTransition.fadeWithColor(SKColor(red: 25.0/255.0, green: 55.0/255.0, blue: 12.0/255.0, alpha: 1), duration: 1.0)) to move from one scene to another. But how can I go back to the original scene? Using the same principle of code

问题 I have a camera in the center of SceneKit scene at position(0,0,0) I'm rotation the camera around the y-axis to show different parts of the scene. I want to show arrows at the left/right side of my screen to show in which direction the user has to move to view a target object. How can I calculate if a ScnNode is positioned at the left of right side of my view direction? I know: position and rotation of the camera node position of the target node 回答1: Calculate the vector to the node relative

问题 I create the AVAudioPlayer object and play the music within the scene, if i transition through to another scene and then go back to the original scene it creates another object and plays the same soundtrack twice. How do i overcome this ? NSURL *url = [[NSBundle mainBundle] URLForResource:@"backgroundMusic" withExtension:@"mp3"]; self.backgroundMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil]; self.backgroundMusic.numberOfLoops = -1; [self.backgroundMusic prepareToPlay]; if
