问题 Xcode is dropping an error and I dont know how to solve it. Maybe someone can give me a hand or a good hint? Here is my code that is working within my Game Scene: var currentLevel: Int = 1 var platforms: PlatformsNode! var platformNode1: PlatformNode! var platformNode2: PlatformNode! var platformNode3: PlatformNode! var platformArray = [SKNode]() let passenger = SKSpriteNode(imageNamed: "passenger") var passengerNumber:Int = 1 var startPlatform = [3, 3, 2, 1, 2] var destinationPlatform = [1,

问题 I have a sks file containing a scene (GameScene class), and I implemented initWithCoder: in GameScene. I'm trying to load the scene in the controller this way: let file = NSBundle.mainBundle().pathForResource("GameScene", ofType: "sks")! if let scene = NSKeyedUnarchiver.unarchiveObjectWithFile(file) as? GameScene {...} But the block is never executed and initWithCoder: is never called. 来源： https://stackoverflow.com/questions/35234887/failed-to-load-a-scene-from-an-sks-file

问题 Hopefully someone can help. I have been pulling my hair out on this one! Below is some of the control pad code from my Sprite Kit game which uses applyForce to move the hero ship. I like how the controls and movement feel, its got some nice drift, etc... However I have inconsistent results on the animation/movement it produces. Sometimes (about half the time) the animation is perfectly smooth and looks correct. The rest of the time the ship movement animation stutters at different intensities

问题 I struggling with the following Problem: I've made a game with SpriteKit. I implemented the GameCenter to my game. It works. Player logs in automatically and the highscore will be added to the default Leaderboard. But for example in the "EndScreen" I want to show the GameCenterLeaderboard . Appledocumentation tells me that I should use the following code: - (void) showGameCenter { GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init]; if

问题 This question is in reference to this one: Object positioning is off so I implemented the code again: let xAxisSpawnLocations: [CGFloat] = { var spawnLocations:[CGFloat] = [] //Create 5 possible spawn locations let numberOfNodes = 5 for i in 0...numberOfNodes - 1 { /* Spacing between nodes will change if: 1) number of nodes is changed, 2) screen width is changed, 3) node's size is changed. */ var xPosition = (frame.maxX - player.size.width) / CGFloat((numberOfNodes - 1)) * CGFloat(i) //add a

问题 I am making a simple Pong game using SpriteKit + Swift. It is a multiplayer game, so I want two people to be able to move the two paddles. I want to be able to move the paddles at the same time. When I run the code below, which is the touchesBegan function, I am only able to move each paddle when one finger is pressing the display. When I try to touch another paddle, while my finger is already on the screen, it does not respond. let touch = touches.first as UITouch? let touchLocation = touch?

问题 How do you implement SKActionTimingFunction in objective-c?. I've looked everywhere and I just found an example in swift. Thanks! 回答1: heres an example moveAction.timingFunction = ^float(float t){ return sin(t * M_PI/2); }; man i hate blocks in objective-c 回答2: In Swift 4.2: moveAction.timingFunction = { time -> Float in return sin(time * .pi/2) } 来源： https://stackoverflow.com/questions/28520521/how-to-implement-skactiontimingfunction

问题 I have a Sprite Kit game that first displays a menu screen. The game starts when you tap anywhere on the screen. I am displaying iAd's. The problem I have is when a user taps the iAd banner to view the add, GameScene is responding to the tap and starting the game. Ideally I want to detect that the touch was on the iAd banner and not start the game in this case. GameScene.m -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { // I dont want to start game if the touch was on the

问题 I am recently working on sprite kit to create a simple game where user input name as identity and moves forward to play game and has option to edit name or replace name. Which is best option to use uitextfield : in skscene or viewcontroller ? Or any other solutions? I had tried with uitextfield adding in skscene but got memory issue (since i called scene from viewwilllayoutSubview override func viewWillLayoutSubviews() { let skView = self.view as! SKView skView.ignoresSiblingOrder = true let

问题 Ok, so after testing on the simulators it turns out that this issue is only occurring on actual devices ... How would I fix this? I am making an iOS app with SpriteKit and am implementing iAD. Everything works more or less like I expect it too, except for one thing. When I tap on the ad, it brings me to a full screen ad, as expected, but when I close that ad the current view freezes, as in nothing happens visually. I know the app is still running because when I click the banner ad again and
