skscene

I use a dispatch_once NSObject to create data pointers. So all game asset pointers are made when the main viewcontroller appears. In order to play a game, the user taps a UIButton corresponding to a particular level on a UIViewController . Let me call it LevelSelectionController. When the game is over, the user will tap a label ( SKLabel ). And all actions and nodes will be removed. [self removeAllActions]; [self removeAllChildren]; [self removeFromParent]; Moreover, an SKScene subclass for a particular level delegates the task of returning the user to LevelSelectionController to the

I am pausing my SKScene using the following code: self.paused = YES; However, according to this answer by Andrey Gordeev , one can also pause a scene using this line: self.view.paused = YES; I would like to understand what difference it would make to call the either (or both) to pause a scene. Andrey Gordeev Pausing SKView stops calling update: method for SKScene . Pausing SKScene doesn't do that. I usually pause both SKScene and SKView EDIT: As of iOS9 pausing the scene will pause the update: method. The effect is the same. You still have the paused property on the scene because it's a

I am trying to create a simple 2d platform game using Swift, SpriteKit, and SKTileMaps. But every time i change between scenes containing SKTileMaps I see a lot of memory leaks in the Xcode Instruments. I have recreated the problem as simple as I can. I am using a .sks file to create the scene and this file only contains 1 tileMap filled with some tiles. The code in the view controller for presenting the scene: if let view = self.view as! SKView? { let scene = LoadingScene(size: CGSize(width: 2048, height: 1536)) scene.scaleMode = .aspectFill view.presentScene(scene) The code for the scene:

I understand that the iPhone 5s has a pixel resolution of 640 x 1136 and a point resolution of 320 x 568 (for backward compatibility with non-Retina devices). The problem/confusion/oddity seems to come in when I'm working with SpriteKit. Example: I'm drawing a line from bottom-left corner (0, 0) to top-right corner (width, height). The result was that the line was drawn almost halfway. And indeed when i print out the screen size, it should 320 x 568. So i decided to draw from (0, 0) to (width * 2, height * 2). And of course, this printed out 640 x 1136. So the oddity is this: Even though I'm

This code, intending to present the user with the UIViewController "menu", instead greets them with a black screen. let currentViewController:UIViewController=UIApplication.shared.keyWindow!.rootViewController! let mymenu = menu() currentViewController.present(mymenu, animated: true, completion: nil) I'm transitioning from a SKScene . To present a SKScene from another SKScene you should do for example : let nextScene = MainScene(size: self.scene!.size) self.scene?.view?.presentScene(nextScene, transition: SKTransition.doorway(withDuration: 1)) You don't need to retrieve your
