Hello! Bare with me here, as there is a lot to explain! I am working on implementing a Game Center high score leaderboard into my game. I have looked around for examples of how to properly implement this code, but have come up short on finding much material. Therefore, I have tried implementing it myself based off information I found on apples documentation. Long story short, I am getting success printed when I update my score, but no scores are actually being posted (or at-least no scores are showing up on the Game Center leaderboard when opened). Before I show the code, one thing I have questioned is the fact that this game is still in development. In AppStoreConnect, the status of the leaderboard is "Not Live". Does this affect scores being posted? Onto the code. I have created a GameCenter class which handles getting the leaderboards and posting scores to a specific leaderboard. I will post the code in whole, and will discuss below what is happening. PLEASE VIEW ATTACHED TEXT TO SEE THE GAMECENTER CLASS! GameCenter class - https://developer.apple.com/forums/content/attachment/0dd6dca8-8131-44c8-b928-77b3578bd970 In a different GameScene, once the game is over, I request to post a new high score to Game Center with this line of code: GameCenter.shared.submitScore(id: GameCenterLeaderboards.HighScore.rawValue) Now onto the logic of my code. For the longest time I struggled to figure out how to submit a score. I figured out that in Xcode 12, they deprecated a lot of functions that previously worked for me. Not is seems that we have to load all leaderboards (or the ones we want). That is the purpose behind the leaderboards private variable in the Game Center class. On the start up of the app, I call authenticate player. Once this callback is reached, I call loadLeaderboards which will load the leaderboards for each string id in an enum that I have elsewhere. Each of these leaderboards will be created as a Leaderboard object, and saved in the private leaderboard array. This is so I have access to these leaderboards later when I want to submit a score. Once the game is over, I am calling submitScore with the leaderboard id I want to post to. Right now, I only have a high score, but in the future I may add a parameter to this with the value so it works for other leaderboards as well. Therefore, no value is passed in since I am pulling from local storage which holds the high score. submitScore will get the leaderboard from the private leaderboard array that has the same id as the one passed in. Once I get the correct leaderboard, I submit a score to that leaderboard. Once the callback is hit, I receive the output "Successfully submitted score to leaderboard". This looks promising, except for the fact that no score is actually posted. At startup, I am calling updatePlayerHighScore, which is not complete - but for the purpose of my point, retrieves the high score of the player from the leaderboard and is printing it out to the console. It is printing out (0), meaning that no score was posted. The last thing I have questions about is the context when submitting a score. According to the documentation, this seems to just be metadata that GameCenter does not care about, but rather something the developer can use. Therefore, I think I can cross this off as causing the problem. I believe I implemented this correctly, but for some reason, nothing is posting to the leaderboard. This was ALOT, but I wanted to make sure I got all my thoughts down. Any help on why this is NOT posting would be awesome! Thanks so much! Mark

GCVirtualController isn't displaying when used with SKScene class. The Virtual controllers appear but then it seems that they are obscured by the SKScene itself!? The documentation says that calling connect() will display the virtual controllers but I seem to be missing how to add the controllers to the SKScene? class GameScene: SKScene { private var _virtualController: Any? @available(iOS 15.0, *) public var virtualController: GCVirtualController? { get { return self._virtualController as? GCVirtualController } set { self._virtualController = newValue } } override func didMove(to view: SKView) { let background = SKSpriteNode(imageNamed: ".jpg") background.zPosition = -1 addChild(background) let virtualConfig = GCVirtualController.Configuration() virtualConfig.elements = [GCInputLeftThumbstick, GCInputRightThumbstick, GCInputButtonA, GCInputButtonB] virtualController = GCVirtualController(configuration: virtualConfig) virtualController?.connect() } } I've also tried adding the virtual controllers in the UIViewController but this doesn't work either.

I've an app I've been working on for quite some time now. It uses SpriteKit. The windows with the scenes in them are generated programmatically. All of a sudden, when it's up and running through XCode, the console throws out a continuous stream of errors - probably in the order of 1 per second. The main one that makes up this stream is: 2022-03-07 20:07:38.765930+0000 My*App[8461:465673] [] CurrentVBLDelta returned 0 for display 1 -- ignoring unreasonable value But others that appear slightly less frequently are: 2022-03-07 20:07:38.447800+0000 My*App[8461:465143] Metal GPU Frame Capture Enabled 2022-03-07 20:07:38.448070+0000 My*App[8461:465143] Metal API Validation Enabled 2022-03-07 20:07:38.613097+0000 My*App[8461:465640] [] [0x7f9596053820] CVCGDisplayLink::setCurrentDisplay: 1 2022-03-07 20:07:38.613415+0000 My*App[8461:465640] [] [0x7f9596053820] Bad CurrentVBLDelta for display 1 is zero. defaulting to 60Hz. 2022-03-07 20:07:38.613442+0000 My*App[8461:465640] [] [0x7f9596053800] CVDisplayLinkCreateWithCGDisplays count: 1 [displayID[0]: 0x1] [CVCGDisplayLink: 0x7f9596053820] 2022-03-07 20:07:38.613467+0000 My*App[8461:465640] [] [0x7f9596053800] CVDisplayLinkStart 2022-03-07 20:07:38.613487+0000 My*App[8461:465640] [] [0x7f9596053820] CVDisplayLink::start 2022-03-07 20:07:38.613541+0000 My*App[8461:465640] [] [0x7f9596053800] CVDisplayLinkStart 2022-03-07 20:07:38.613575+0000 My*App[8461:465640] [] [0x7f9596053820] CVDisplayLink::start 2022-03-07 20:07:38.613634+0000 My*App[8461:465671] [] [0x600000c09f10] CVXTime::reset 2022-03-07 20:07:38.613718+0000 My*App[8461:465671] [] CurrentVBLDelta returned 0 for display 1 -- ignoring unreasonable value 2022-03-07 20:07:38.639810+0000 My*App[8461:465671] [] CurrentVBLDelta returned 0 for display 1 -- ignoring unreasonable value 2022-03-07 20:07:38.639887+0000 My*App[8461:465671] [] [0x7f9596053820] CVCGDisplayLink::getDisplayTimes display: 1 -- SLSDisplayGetCurrentVBLDelta returned 0 => generating fake times 2022-03-07 20:07:38.673702+0000 My*App[8461:465653] [] [0x7f9596053820] CVCGDisplayLink::setCurrentDisplay: 1 2022-03-07 20:07:38.673748+0000 My*App[8461:465653] [] [0x7f9596053820] CVDisplayLink::stop 2022-03-07 20:07:38.673862+0000 My*App[8461:465653] [] [0x7f9596053820] Bad CurrentVBLDelta for display 1 is zero. defaulting to 60Hz. 2022-03-07 20:07:38.673883+0000 My*App[8461:465653] [] [0x7f9596053820] CVDisplayLink::start I really don't know how else to describe this. I can only imagine having to hand over the entire project as lately I've only been working on the storyboard file so how would this affect it? To be honest the only change I can see is my upgrade to OSX 12.2.1. It's definitely something to do with SpriteKit since not initialising a window with a scene in it stops the errors from showing.

HELLO WORLD! I am currently developing an amazing Unity mini Game. The game development has come to the deploying stage. Using Unity allows me to deploy this game on MacOS, iOS, Android and Windows which is fantastic . However, I really need this game to have the iOS widget extension as a key feature on mobile. Just like the "Steve" dinosaur game which can be played in widget. I had seen a lot of tutorials and youtube videos but still cant find a solution which make Unity iOS app into a widget. If I really want to make widget Game on iOS, do I need to develop the whole game all over again in xcode or using GameKit? Really hoping there's a way to simply convert the Unity iOS app into a widget.

Hello there 👋 I've noticed a different behavior between iOS 15 and iOS 16 using CIFilter and SpriteKit. Here is a sample code where I want to display a text and apply a blurry effect on the same text in the back of it. Here is the expected behavior (iOS 15): And the broken behavior on iOS 16: It looks like the text is rotated around the x-axis and way too deep. Here is the sample code: import UIKit import SpriteKit class ViewController: UIViewController {     var skView: SKView?     var scene: SKScene?     override func viewDidLoad() {         super.viewDidLoad()         skView = SKView(frame: view.frame)         scene = SKScene(size: skView?.bounds.size ?? .zero)         scene?.backgroundColor = UIColor.red         view.addSubview(skView!)         skView!.presentScene(scene)         let neonNode = SKNode()         let glowNode = SKEffectNode()         glowNode.shouldEnableEffects = true         glowNode.shouldRasterize = true         let blurFilter = CIFilter(name: "CIGaussianBlur")         blurFilter?.setValue(20, forKey: kCIInputRadiusKey)         glowNode.filter = blurFilter         glowNode.blendMode = .alpha         let labelNode = SKLabelNode(text: "MOJO")         labelNode.fontName = "HelveticaNeue-Medium"         labelNode.fontSize = 60         let labelNodeCopy = labelNode.copy() as! SKLabelNode         glowNode.addChild(labelNode)         neonNode.addChild(glowNode)         neonNode.addChild(labelNodeCopy)         neonNode.position = CGPoint(x: 200, y: 200)         scene?.addChild(neonNode) } }

I'm trying to create a Apple Watch game using Xcode 14.2 and watchOS 9. Getting started creating a watchOS App seems pretty straight forward, and getting started creating a game project via the starter template seems easy enough. Trying to put these two together though doesn't seem to work (or is not straight foward). The documentation specifies limitations on what libraries can be used with watchOS noting WKInterfaceSKScene, but doesn't give any specific examples of how to start out a WatchOS project using this. Additionally nearly every online tutorial that I'm able to find uses Storyboards to create a watchOS game, which does not seem to be supported in the latest version of watchOS or Xcode. Can anyone provide example starter code using the watchOS App project starter that that loads with a small colored square on the screen that moves from left to right using the WKInterfaceSKScene library? I've tried the Apple documentation, asking ChatGPT for a sample or reference links, and various tutorials on YouTube and elsewhere.

I have multiple images that at various times I need to replace a target image for a SKSpriteNode. Each of these multiple images has a different size. The target SKSpriteNode has a fixed frame that I want to stay fixed. This target is created via: myTarget = SKSpriteNode(imageNamed: “target”) myTarget.size = CGSize(…) myTarget.physicsBody = SKPhysicsBody(rectangleOf: myTarget.size) How do I resize each of the multiple images so that each fills up the target frame (expand or contract)? Pretend the target is a shoebox and each image is a balloon that expands or contracts to fill the shoebox. I have tried the following that fails, that is, it changes the size of the target to fit the new image .. in short, it does the exact opposite of what I want. let newTexture = SKTexture(imageNamed: newImage) let changeImgAction = SKAction.setTexture(newTexture, resize: true) myTarget.run(changeImgAction) Again, keep frame of myTarget fixed and change size of newTexture to fit the above frame ..

Mac Studio won't show scene in canvas assist

Hi, I'm creating a SF Symbols image like this: var img = UIImage(systemName: "x.circle" ,withConfiguration: symbolConfig)!.withTintColor(.red) In the debugger the image is really red. and I'm using this image to create a SKTexture: let shuffleTexture = SKTexture(image: img) The texture image is ALWAYS black and I have no idea how to change it's color. Nothing I've tried so far works. Any ideas how to solve this? Thank you! Best Regards, Frank

Xcode will try to open to the last opened project, which caused the crash, but it will just crash again. Any suggestions? Edit: I submitted the logs to apple and a restart did not resolve.

I love the new UIImage(resource:) initializer that uses the automatically generated symbols for my image assets. However, there does not appear to be an equivalent in SpriteKit so I am forced to still use SKSpriteNode(imageNamed:) I am using Xcode 15 Beta 7. Will this be included when Xcode 15 goes into production?

I'm trying to animate a shape (e.g. a circle) to follow a custom path, and struggling to find the best way of doing this. I've had a look at the animation options from SwiftUI, UIKit and SpriteKit and all seem very limited in what paths you can provide. Given the complexity of my path, I was hoping there'd be a way of providing a set of coordinates in some input file and have the shape follow that, but maybe that's too ambitious. I was wondering if this were even possible, and assuming not, if there were other options I could consider.

I have a sprite kit scene with an edge loop physics body set programmatically with the category bit mask set to a custom Physics Category called Edge. Through the scene editor, I've added several sprite nodes with varying physics body types and various category masks and collision masks. The collision mask for a particular sprite node includes the Edge category. Initially, I have this node partially off the screen on the scene editor but when I run the program, it appears completely inside the edge loop. Is it possible to have a sprite node be positioned partially inside the edge loop and partially outside the edge loop?

I'm trying to add a SpriteKit scene to my view using SpriteView(scene:SKScene(fileNamed: "SceneName")!). This works well, but how can I interact with the scene? Thanks in advance for your answer ❤️

Hi all So I'm quite new into GameDev and am struggling a bit with the Tilemap All my elements have the size of 64x64. As you can see in my screenshot there is some gap between the street and the water. It might be simple but what's the best way to fix that gap? I could increase the width of the left and right edge png but then I will sooner or later run into other problems as it then is not fitting with the rest. Thanks for your help Cheers from Switzerland

All our custom Playground Books using SpriteKit stopped working after upgrading to SwiftPlaygrounds version 4.4 To reproduce the issue, simply create a new book by clicking the top right hand icon and in the book add two lines of code. import SpriteKit let circle = SKShapeNode(circleOfRadius: 100.0) The second line produces an error. I tried with other classes. SKAction seems to work. SKSpriteNode, SKTexture etc have the same issue. Please help. Our students are stuck!
