Here is my solution to the scrolling problem. It revolves around “stealing” the behaviour from the UIScrollView. I learned this from a WWDC Video from 2012 about mixing UIKit with OpenGL. Add the UIScrollViewDelegate methods to your ViewController and set the scroll view delegate to the ViewController Add/Move the PanGestureRecognizer from the UIScrollView to the … Read more
Use SKView‘s isPaused property: Swift: scene.view?.isPaused = true Objective C: self.scene.view.isPaused = YES; This will stop all actions and physics simulation.
In Sprite Kit you don’t have access to texture data. Instead you’d have to create a bit mask from the image, for example by loading the image as UIImage or CGImage and scanning for all non-transparent pixels.
the reason this doesnt work is that you are creating a NEW instance of GameViewController and then you’re calling gameOver on that. What you really want to do is reference your existing GameViewController theres a few ways to do this, I’ll give you one example. add a viewController property to your GameScene class class GameScene … Read more
Unfortunately, SKShapeNode is not that great for what you are trying to do. However, there is a way to optimize this, albeit with some caveats. First one of the largest problems with the fps is that the draw count gets extremely high because each line segment you add is another draw. If you set showsDrawCount … Read more
This appears to be an issue with collision detection. Most have found solutions by using the didBeginContact and reapplying the force at an opposite direction. Note he says didMoveToView but corrects himself in a later comment to didBeginContact. See comments at the bottom of the Ray Wenderlich tutorial here I have a fix for the … Read more
You can use one like this: var timer = NSTimer() override func viewDidLoad() { scheduledTimerWithTimeInterval() } func scheduledTimerWithTimeInterval(){ // Scheduling timer to Call the function “updateCounting” with the interval of 1 seconds timer = NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: Selector(“updateCounting”), userInfo: nil, repeats: true) } func updateCounting(){ NSLog(“counting..”) } Swift 3: var timer = Timer() override … Read more
I’ve writen a small ‘starter’ project that demonstrates in a simple way (I hope) a lot of the concepts – just drop the code into a new project and run : Here is a simple Sprite-Kit GameScene.swift. Create a new, empty SpriteKit project and replace the GameScene.swift with this. Then build and run. Click on … Read more
Moving multiple nodes simultaneously is fairly straightforward. The key is to track each touch event independently. One way to do that is to maintain a dictionary that uses the touch event as the key and the node being moved as the value. First, declare the dictionary var selectedNodes:[UITouch:SKSpriteNode] = [:] Add each sprite touched to … Read more
You are calling the segue on the root viewController. I think that is the problem. You need to call the segue on the scene’s viewController instead (where I am assuming you have created the segue, hence it is not being found on the root viewController). Now the problem is that an SKScene does not have … Read more
