You can’t “bring it to front” but you can change the zPosition of it. The higher the zPosition of the node the later it gets rendered. So if you have three nodes with zPositions of -1, 0 and 1 then the -1 will appear at the back. Then the 0. Then 1 will appear at … Read more
To get a rounded corner node you can use 2 approaches, each of them requires use of SKShapeNode. First way is to use SKShapeNode and set its path to be a rounded rectangle like this: SKShapeNode* tile = [SKShapeNode node]; [tile setPath:CGPathCreateWithRoundedRect(CGRectMake(-15, -15, 30, 30), 4, 4, nil)]; tile.strokeColor = tile.fillColor = [UIColor colorWithRed:0.0/255.0 green:128.0/255.0 … Read more
In iOS 8, you can set the scene’s SKView to allow transparency and set the scene’s background color to have transparency. Then views behind the SKView will be seen. UIView *parentView = …; [parentView addSubview:backgroundView]; [parentView addSubview:skViewWithScene]; skViewWithScene.allowsTransparency = YES; scene.backgroundColor = [UIColor clearColor]; [skViewWithScene presentScene:scene];
Create a SKScene in your UIView to add a SKEmitterNode particle effect. One way of doing this: 1.In storyboard (or programatically if you prefer) add a View object on top of the existing View and resize it to your needs. 2.Change the class of the new view to SKView 3.In your view controller .h file … Read more
You are looking for a fluid simulator This is indeed possible with modern hardware. Let’s have a look at what we are going to build here. Components In order to achieve that we’ll need to create several molecules having a physics body and a blurred image use a Shader to apply a common color to … Read more
I’m trying to set up some elastic collisions using Sprite Kit I think you’re misunderstanding the physics in play here. An elastic collision is an oversimplification of a collision. In reality, no collision results in a perfect transfer of energy. I’ve explained the physics here in an answer to the related question you linked to. … Read more
Using SKShapeNode you can draw line or any shape. SKShapeNode *yourline = [SKShapeNode node]; CGMutablePathRef pathToDraw = CGPathCreateMutable(); CGPathMoveToPoint(pathToDraw, NULL, 100.0, 100.0); CGPathAddLineToPoint(pathToDraw, NULL, 50.0, 50.0); yourline.path = pathToDraw; [yourline setStrokeColor:[SKColor redColor]]; [self addChild:yourline]; Equivalent for Swift 4: var yourline = SKShapeNode() var pathToDraw = CGMutablePath() pathToDraw.move(to: CGPoint(x: 100.0, y: 100.0)) pathToDraw.addLine(to: CGPoint(x: 50.0, y: … Read more
This is a little confusing – here’s how I understand it (this is in reference to the top image): 1x images are for the original iPhone through the 3GS – ‘standard’ resolution devices (3.5″ screens) 2x images are for the iPhone 4 and 4S (3.5″ Retina screens) and are also used for the iPhone 6. … Read more
Adding the following code will fix your problem (code is in Swift): scene.scaleMode = SKSceneScaleMode.ResizeFill Now if you want to know why this fixes your problem, what your problem actually is, and how to handle multiple resolutions – I suggest you continue reading. There are three things that can impact the position of nodes in … Read more
