I created my game using the Universal images of dimensions 1136x640 (#2x) and 2208x1242 (#3x) for my start background. I changed the scaleMode property to .fill for iPad but it just fills the center with black borders all around. I thought .fill was suppose to extend the width and height to fill the scene view.
I found a sample universal project that I tested and the images scaled with .fill for the iPad. They used, 568x320 (#1x), 1136x640 (#2x) and 1704x960 (#3x) for their images. I copied the images into my project and tested for iPad and still got the black surrounding.
What is causing the black border for the iPad?
What explicit dimensions should I use for my universal game for #1x, #2x, #3x background so that when I set scaleMode to .fill for iPad it will fill the scenes width and height?
Below is my how I set the StartBackgroundScene scene in the GameViewController
override func viewWillLayoutSubviews() {
super.viewWillLayoutSubviews()
let skView = self.view as? SKView
if skView?.scene == nil {
skView?.showsFPS = true
skView?.showsNodeCount = true
skView?.showsPhysics = false
skView?.ignoresSiblingOrder = false
let startBackgroundScene = StartBackgroundScene(size: skView!.bounds.size)
startBackgroundScene.scaleMode = .fill
skView?.presentScene(startBackgroundScene)
}

I'm a newbie in Swift and SpriteKit. I'm trying to develop a simple 2D game for iPhone X, so I want to draw a playable area where I can put game's sprites. The problem is that when I draw the rectangle it fits the screen width, but not the screen height.
The GameScene size is 2048x1536, with anchor point in (0.5, 0.5).
The default screen orientation is landscape.
This is what I did at the moment:
GameViewController.swift
class GameViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
if let view = self.view as! SKView? {
// Load the SKScene from 'GameScene.sks'
if let scene = SKScene(fileNamed: "GameScene") {
// Set the scale mode to scale to fit the window
scene.scaleMode = .aspectFill
// Present the scene
view.presentScene(scene)
}
view.ignoresSiblingOrder = true
view.showsFPS = true
view.showsNodeCount = true
}
}
}
GameScene.swift
class GameScene: SKScene {
override func didMove(to view: SKView) {
let rectangle = SKShapeNode(rect: self.frame)
rectangle.strokeColor = .green
rectangle.lineWidth = 20
rectangle.zPosition = 1
addChild(rectangle)
}
}
When I run this code, the rectangle green borders fit the width of the screen (in landscape), so I can see them, but the top and bottom borders are off-screen.
My purpose is to have a playable rect as high as the phone screen, and his width should be screen width - left safe area insets (to exclude the notch from the playable area).
Thank you.
When using aspect fit in swift, the sides of the screen are removed. Is there a way I can cover this up by using a background colour to fill the whole screen or use a background image?
Here is the code for creating the scene as aspect fit in the GameViewController
if let view = self.view as! SKView? {
if let scene = SKScene(fileNamed: "mainMenu") {
// setting scene here to aspect fit
scene.scaleMode = .aspectFit
// Present the scene
view.presentScene(scene)
}
view.ignoresSiblingOrder = true
view.showsFPS = true
view.showsNodeCount = true
}
scene with aspect fit and background set to clear
scene with aspect fill
scene with aspect fit and background set to green
Make sure you set the screen size for the scene.
let screenWidth = UIScreen.main.bounds.width
let screenHeight = UIScreen.main.bounds.height
scene?.size = CGSize(width: screenWidth, height: screenHeight)
After, set scene.scaleMode = .aspectFill
If this doesn’t work, you can try and set the background color by doing this, but I’m unaware if this option will give you what you’re looking for as I didn’t test it.
scene?.backgroundColor = UIColor.white //color you want
Otherwise try setting scene?.size = image.size
I am having deep trouble understanding how the resolution on different devices work. so what I have done is made a background image 1024 x 768 then tested on an iphone 5 device. when i run it, the bottom half of the screen is chopped off so as the top. I did use AspectFill as my scale mode, but even when i test it on iphone 6 or 6+, the background is still chopped off.
the following is my code for gameviewcontroller
import UIKit
import SpriteKit
class GameViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let scene = GameScene(size: CGSize(width: 1024, height: 768))
let skView = self.view as! SKView
skView.multipleTouchEnabled = true
if GameSettings.Debugging.ALL_TellMeStatus {
skView.showsFPS = GameSettings.Debugging.ALL_ShowFrameRate
skView.showsNodeCount = GameSettings.Debugging.ALL_ShowNodeCount
skView.showsDrawCount = GameSettings.Debugging.IOS_ShowDrawCount
skView.showsQuadCount = GameSettings.Debugging.IOS_ShowQuadCount
skView.showsPhysics = GameSettings.Debugging.IOS_ShowPhysics
skView.showsFields = GameSettings.Debugging.IOS_ShowFields
}
skView.ignoresSiblingOrder = true
scene.scaleMode = .AspectFill
_ = SGResolution(screenSize: view.bounds.size, canvasSize: scene.size)
skView.presentScene(scene)
}
override func shouldAutorotate() -> Bool {
return true
}
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
return .Landscape
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Release any cached data, images, etc that aren't in use.
}
override func prefersStatusBarHidden() -> Bool {
return true
}
}
and my code for adding the background image in.
let background = SKSpriteNode(imageNamed: "Artboard 1")
background.posByCanvas(0.5, y: 0.5)
background.xScale = 1.2
background.yScale = 1.2
background.size = self.frame.size
background.zPosition = -1
addChild(background)
is this the right way to start the screen size or should i start with an iPad screen size then descale it? If anyone can lead me on how to attack this problem that would be great!!
Aspect fill is going to chop off parts of your background.
Your scene has an aspect ratio of 4:3
Your device has an aspect ratio of 16:9
AspectFill will scale your scene in its current aspect ratio(4:3) till the farthest borders are filled, allowing for the entire view to show the scene and have no black borders;
AspectFit will scale till the nearest borders are filled in, which will give you black bars to preserve the aspect ratio.
If you want the 4:3 to not be preserved, then you use .Fill, this of course is going to make your sprites fatter on 16:9 because it will just stretch the scene till it hits all 4 borders
Finally you have .ResizeFill, and what this does is resizes the scene bounds to match your screen size, so if you start with a 1024x768 scene, it will turn it into a 736x414 scene when you view it on iPhone 6+ (This is because we are working in points, not pixels, the pixel count would be x3 (so 2208x1242) which hardware will shrink to 1920x1080).
You need to take a step back and evaluate how you want your game to look on 3 different aspect ratios
16:9,3:2, and 4:3, and determine which of the 4 methods above works best for you.
Now in my opinion, I find that Aspect Fill works best, and I just plan for the 16:9 aspect ratio, making sure I do not put any important information in the areas that may be cropped for a game, but this does not work for everybody, and unfortunately nobody can help you with this part, since it is your game and you are the one that determines its look and feel.
Im making a game with swift and spriteKit with xcode 6.1.
My problem is that, when I run the game on the iPhone 6 or iPhone 6+ the scene/images dont resize properly
I have this on my GameViewController
// Configure the view.
let skView = view as SKView
skView.multipleTouchEnabled = false
// Create and configure the scene.
scene = GameScene(size: skView.bounds.size)
scene.scaleMode = .AspectFill
// Present the scene.
skView.presentScene(scene)
And this on my GameScene
override init(size: CGSize) {
super.init(size: size)
anchorPoint = CGPoint(x: 0.5, y: 0.5)
let background = SKSpriteNode(imageNamed: "Background")
addChild(background)
}
I have tried all the scale modes but they dont seem to work. I hope someone can tell me what is going on
The size of the scene is being set to the size of the view in
scene = GameScene(size: skView.bounds.size)
so it is only the images in the scene that are too small to fill the view.
Make these changes to your GameViewController:
if you set the size of the scene to the size of the background image:
scene = GameScene(size: CGSize(width: backgroundImageWidth, height: backgroundImageHeight))
(replace backgroundImageWidth and backgroundImageHeight with actual values)
then set the scene's scale mode to fill the view:
scene.scaleMode = .Fill
(this may make the scene look stretched, you could use other scale modes)
I am trying to add a couple of nodes to the scene. When I run the app I just have the default gray background. Neither of the nodes appear in the scene. Here is what I have:
class GameScene: SKScene {
override func didMoveToView(view: SKView) {
/* Setup your scene here */
let jumper = SKSpriteNode(imageNamed:"Jumper")
jumper.xScale = 0.25
jumper.yScale = 0.25
jumper.position = CGPointMake(50, 300)
self.addChild(jumper)
let blob = SKSpriteNode(imageNamed:"Blob")
blob.position = CGPointMake(160, 30)
blob.xScale = 0.5
blob.yScale = 0.25
self.addChild(blob)
}
I have checked the image titles and everything is correct there.
The Problem
Your sprites are not visible because your scene is not completely within the simulator's window. By default the scene's size is 1024 x 768 (specified by GameScene.sks), while the simulator is displaying only 375 x 667 points (if you selected the iPhone 6/6s simulator). Unless the scene's size is set correctly, the bottom-left corner of the simulator's window will not be the (0,0) position of your scene.
To correct this issue,
Method 1:
Change the scene's size property in GameScene.sks to match the size of the view. I suggest you set the scene size to 375 x 667 (iPhone 6/6s). If you do this and set the scene's scaleMode property to .AspectFill (the default value), SpriteKit will automatically scale the scene to fit in the view of the iPhone 6+, 6s+, 5, and 5s. This will save you time when porting your game to these devices.
Method 2:
In your view controller, replace this
scene.scaleMode = .AspectFill
with this
scene.scaleMode = .ResizeFill
Warning: Using this method will work but may require additional effort to port your game to other iOS devices with a different screen size.
