Is there a way to have particles spawn with a random per particle colour based on the current "Color Ramp"? The particles do not change colour over their lifespan, they are simply assigned a colour from somewhere along the "Color Ramp" at birth and keep that colour until they die. The result of this would be a mix of particles at birth with blend colours from RED through to BLUE. In my tests I only seem to be able to get the behaviour where particles spawn as RED and then gradually turn to BLUE as the approach the bottom of the screen. John Riselvato Well, It looks like you can't use a

I'm making a game where I need the background color to change slowly. As the user plays the level, the background color should be changing to show progress. I was thinking of having the starting color be light blue, and then changing to green, then yellow, then orange or something like that over time. Any ideas? Here's a working example, just change the colors: var backgroundColours = [UIColor()] var backgroundLoop = 0 override func viewDidLoad() { super.viewDidLoad() backgroundColours = [UIColor.redColor(), UIColor.blueColor(), UIColor.yellowColor()] backgroundLoop = 0 self

On iPhone's with 3D touch enabled, there is a feature where long pressing the left hand side of the screen with enough force opens lets you change which app is active. Because of this, when a non-moving touch happens on the left hand side of the screen, the touch event is delayed for a second or two until the iPhone verifies that the user is not trying to switch tasks and is interacting with the app. This is a major problem when developing a game with SpriteKit, as these touches are delayed by a second every time a user taps/holds their finger on the left edge of the screen. I was able to

I always thought that the the zPosition of a SKNode would be relative to its parent, but right now I'm experiencing the opposite effect. I have two parent SKNodes in my scene, which have a zPosition of 1 (node1) and 2 (node2). What I want to achieve is that node2 should ALWAYS be layered ABOVE node1. But unfortunately, the child nodes of node1 (which have a zPosition of 1-50) are all layered above the child nodes of node2 (which currently have no zPosition). Is there any way to solve this (except giving node2 a zPosition of more than 50)? Maybe some kind of boolean Parameter to set all child

Creating a game with SpriteKit and its actually working out very well. I am using physics and having the ability to see actually where my bodies are because I might have some alpha inside of my sprites will really be helpful. This will also be helpful for creating more precise bodies. In the documentation for SpriteKit they talk about a debugOverlay but the only example they give is to draw the direction of gravity. Here is the link: https://developer.apple.com/library/ios/documentation/GraphicsAnimation/Conceptual/SpriteKit_PG/Actions/Actions.html Scroll to area of debugging overlay. Has

I'm still playing around with learning SpriteKit in iOS & have been doing lots of reading & lots of experimenting. I'm confused by something else I've found* regarding coordinates, frames & child nodes. Consider this snippet of code, in which I'm trying to draw a green box around my spaceship sprite for debugging purposes: func addSpaceship() { let spaceship = SKSpriteNode.init(imageNamed: "rocketship.png") spaceship.name = "spaceship" // VERSION 1 spaceship.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame)) let debugFrame = SKShapeNode(rect: spaceship.frame)
