So I got in my game 3 different scenes: MenuScene, GameScene and GameOverScene. I would like to know how I can get the score variable located in GameScene from GameOverScene so I can show it up there after the player loses. So in GameScene, I created this simple getter: func getScore() -> Int { return self.score } But if I try to do GameScene.getScore() from a different Scene I get an error. Tried using "class" before func class func getScore() -> Int { return self.score } But that also gives me an error from GameScene saying: "Instance member 'score' cannot be used on type GameScene" So how's

I'm trying to create an iOS game and I have it so that when the item is touched and moved it is dragged. When it is dragged the mouse is snapped to the center of the sprite. How could I make it so that this wouldn't happen? Here is an example of what is happening. Here are the functions dealing with touch input override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) { var papers = 0 for touch in (touches as! Set<UITouch>) { let location = touch.locationInNode(self) let touchedNode = nodeAtPoint(location) if ((touchedNode.name?.contains("paper")) != nil) { touchedNode

I've been searching for a solution to pause my SpriteKit game when the user "tabs down" the game. So far I found a solution where you use SKAction 's instead of NSTimer 's, this works as long as the time between actions stays the same. However, my NSTimer 's changes in speed. So I need to find another solution. I have a bunch of NSTimer 's located in GameScene -> didMoveToView NSTimer.scheduledTimerWithTimeInterval(0.2, target: self, selector: Selector("SpawnBullets"), userInfo: nil, repeats: true) NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector("SpawnMeteors"),

I'm making a simple game and I would like to add an iAd at the top of the Game Over Screen. I could add it on to the UIViewController , but then it would show up while playing, which is something I don't want. Is there a way to make the iAd appear only on a certain SKScene ? Thanks for all your help! The most clean solution is to declare and implement a protocol to let the UIViewController know that it should hide the ad. @protocol MySceneDelegate <NSObject> - (void)hideAd; - (void)showAd; @end @interface MyScene : SKScene @property (weak) id <MySceneDelegate> delegate; @end View controller

I have created a SKShapeNode and I have assigned a physicsBody to it. However, it is not being triggered when there is contact. Creation of SKShapeNode code: -(SKShapeNode*)gravityline{ //SKSpriteNode *lolo=[[SKSpriteNode alloc]init]; SKShapeNode *lolo = [[SKShapeNode alloc] init]; CGPoint fff=CGPointMake(ray1.position.x, ray1.position.y); CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, fff.x, fff.y); CGPathAddLineToPoint(path, 0,rayoriginpoint.x,rayoriginpoint.y ); CGPathCloseSubpath(path); lolo.path = path; lolo.name=@"gravityline"; lolo.strokeColor=[SKColor

I'm trying to make a SpriteKit app that has a button to go to my website if the user so desires to. I thought it would be a good practice to make an alert (since it's made for iOS 8, I'd use a UIAlertController ) confirming if they want to be redirected to Safari to see it. Here's what I have in code for the method to make/present this alert so far: UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Go to website" message:@"Would you like to visit DannyDalton.com? This will open Safari." preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction *yes =

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 always led to a major crash.. Whirlwind I made an example where global structure is used to track the
