I have this tableview that is added to my scene by a subclass and it is added like so to the scene
override func didMove(to view: SKView) {
gameTableView.frame = CGRect(x:14,y:70, width: frame.maxX / 1.08, height: frame.maxY/0.9)
self.scene?.view?.addSubview(gameTableView)
gameTableView.reloadData()
universalBackButton = SKSpriteNode(color: SKColor.orange, size: CGSize(width: 100, height: 100))
universalBackButton.position = CGPoint(x:frame.midX - universalBackButton.size.width * 0.7, y: -frame.maxY + universalBackButton.size.height)
universalBackButton.zPosition = 100001
self.scene?.addChild(universalBackButton)
itemShopMenu = SKSpriteNode(color: SKColor.orange, size: CGSize(width: 75, height: 50))
itemShopMenu.position = CGPoint(x:frame.midX + universalBackButton.size.width * 0.7, y: -frame.maxY + itemShopMenu.size.height)
itemShopMenu.zPosition = 100001
self.scene?.addChild(itemShopMenu)
}
But when I go to add buttons so I can leave the tableview scene they're behind the tableview and not in front of it. I have had little to no experience using subviews with scenes and don't know how to get the spritenodes to be in front of the tableview instead of behind it so they can be tapped to execute a function. is there anyway I can add the spritenodes in front of the tableview so they can be pressed?
SpriteKit is optimized for layering sprites within an SKView - not for placing above other UIViews. Why not achieve the same effect by creating UI buttons and layering them on top instead of using sprites as buttons?
let universalBackButton = UIButton()...

In my project I have a pinch to resize option for the object that has been placed in scene view. But when someone pinch the screen to reduce or enlarge the actual size of the object I need to get that scale. I need to display the scale in which the object is being changed in the screen. How do I get the scale when the action is being performed?
Thank you
Within your main ViewController Class for the ARSCNView
declare the label view, and the label itself at the top.
let scaleLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 300, 70))
let labelView = UIView(frame: CGRect(x: 300, y: 300, width: 300, height: 70))
Now within LoadView or ViewDidLoad you can set the attributes for the label such backgroundColor, textColor etc... and also add the view and label to sceneView.
// add your attributes for label,view
labelView.backgroundColor = .clear
scaleLabel.textColor = .white
scaleLabel.adjustsFontSizeToFitWidth
// add you views to sceneView
labelView.addSubview(scaleLabel)
sceneView.addSubview(labelView)
Lastly, with the pinch gesture function for scaling.. which should look something like this.
#objc func pinchGesture(_ gesture: UIPinchGestureRecognizer) {
if nodeYouScale != nil {
let action = SCNAction.scale(by: gesture.scale, duration: 0.1)
nodeYouScale.runAction(action)
gesture.scale = 1
// this part updates the label with the current scale factor
scaleLabel.text = "X: \(nodeYouScale.scale.x) Y: \(nodeYouScale.scale.y) Z:\(nodeYouScale.scale.z)"
} else {
return
}
I am currently making an iOS game in which a ball must bounce within a frame defined by the below image:
The game relies on the below method to automatically create and assign a physics body to the frame surrounding the game.
frame.physicsBody = SKPhysicsBody(texture: frameTexture, size: frame.size)
This code, however, assigns a body that encompasses the outside of the image, rather than the interior, and thus treats the blank interior as a solid object. This, in turn, means that the ball cannot be inside the frame and is forced off the screen immediately after being spawned.
Is there any way to give a physics body an interior?
Another post here: SpriteKit SKPhysicsBody with Inner Edges aims to do something similar, but does not involve automatic wrapping around a texture (hence the new question)
You can use init(edgeLoopFrom:) initializer to achieve inner edge friction. you can use this code below:
override func didMove(to view: SKView) {
//Setup scene's physics body (setup the walls)
physicsBody = SKPhysicsBody(edgeLoopFrom: frame)
let back = SKSpriteNode(imageNamed: "1")
back.position = CGPoint(x: frame.midX, y: frame.midY)
back.size = CGSize(width: 500, height: 600)
back.zPosition = -3
let rect = CGRect(origin: CGPoint(x: -back.size.width/2, y: -back.size.height/2), size: back.size)
back.physicsBody = SKPhysicsBody(edgeLoopFrom: rect)
addChild(back)
//Add Red ball "inside" the back sprite
let red = SKShapeNode(circleOfRadius: 20)
red.fillColor = .red
red.strokeColor = .clear
red.position = back.position
red.physicsBody = SKPhysicsBody(circleOfRadius: 20)
red.physicsBody?.restitution = 1
red.physicsBody?.friction = 0
red.zPosition = 1
red.physicsBody?.affectedByGravity = false
addChild(red)
red.physicsBody?.applyImpulse(CGVector(dx: 20, dy: 15))
}
please follow this Question and have a look to the answer given below.
i am providing a screenshot of my project
I'm trying to add corner radius + dropdown shadow to my UICollectionView Cell,
my Cell sturcuture is like this:
I added view to add shadow on it, and try to add corner radius to the to subviews: the white one and the imageview, I used the following code:
let frame = CGRect(x:0, y: 0, width: UIScreen.main.bounds.width, height: 80)
shadowingViewOutlet.layer.masksToBounds = false
shadowingViewOutlet.layer.shadowColor = UIColor.black.cgColor
shadowingViewOutlet.layer.shadowOffset = CGSize(width: CGFloat(0.0), height: CGFloat(3.0))
shadowingViewOutlet.layer.shadowOpacity = 0.5
if shadowingViewOutlet.layer.shadowPath != nil {
shadowingViewOutlet.layer.shadowPath = UIBezierPath(roundedRect:frame, cornerRadius:3).cgPath
}
but that dosen't work fine!
Anyone try to apply the same functionlaity to UICollectionViewCell and have a result in it?
please help.
Thanks.
I'm developing a small game using Swift & SpriteKit. When I add a SKSpriteNode for Restart button, it doesn't scale properly.
The size of Restart button is 100px in height and width. If I don't set scale , it covers the whole screen and make the screen appear white. I figured out that if I setScale to 0.005 only than it appears on screen, but not in proper size.
import Foundation
import SpriteKit
class EndScene: SKScene {
var restartBtn = SKSpriteNode()
override func didMoveToView(view: SKView) {
background()
restartGame()
}
func restartGame() {
restartBtn = SKSpriteNode(imageNamed: "restartBtn")
restartBtn.setScale(0.005)
restartBtn.position = CGPoint(x: self.size.width / 2, y: self.size.height / 4)
restartBtn.zPosition = 1
self.addChild(restartBtn)
}
func background() {
let bkg = SKSpriteNode(imageNamed: "Background")
bkg.size = self.frame.size
bkg.position = CGPoint(x: self.frame.width / 2, y: self.frame.height / 2)
bkg.zPosition = -2
self.addChild(bkg)
}
}
Here is the output of this code,
Restart Button Output
UPDATE
I put scene!.scaleMode = .AspectFill right inside didMoveToView function and it helped in rendering the shape of the SpriteNode properly. But still I have to setScale(0.001) to make the size of Restart button fit in the screen. Can anyone assist me what line of code I'm still missing?
Instead of using .setScale try using restartBtn.size = CGSize(Width: 50, Height: 50)
This uses the Sprite Kit's resize formula.
I ran into this as well. It happened when I forgot to specify the size of the scene. Instead of calling initWithSize I just wrote init and the scene started to scale down all nodes by x1000. Nodes were visible, but they required a scale of 0.001
I am trying to learn Swift by creating my own game (app), but I am having a problem.
I have a SKSpriteNode which I use as the background for the game. It's an image I've made. My problem is that my background won't fill the view so I get these grey bars outside of the Node.
What is wrong in my code?
override func didMoveToView(view: SKView) {
/* Setup your scene here */
Hintergrund = SKSpriteNode(imageNamed: "PenaltyLocker_BG1")
Hintergrund.size = CGSize(width: view.frame.width, height: view.frame.height)
Hintergrund.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height/2)
Hintergrund.zPosition = 1
Hintergrund.name = "Hintergrund"
addChild(Hintergrund)
Now when I start the simulator for iPhone it looks like this: http://imgur.com/a/mBOWn
Change to use the size of the SKScene.
self.scene.size.width / self.scene.size.height
Hintergrund.size = CGSize(width: self.scene.size.width, height: self.scene.size.height)
Hintergrund.position = CGPoint(x: self.scene.size.width/2, y: self.scene.size.height/2)
