Hello I'm new into developing and right now I'm working on an AR application which works with image tracking and it should play different videos on different tracked images.
Right now the video stops, how can I loop the video?
Also if the image is not in the camera view, the video continues. Is there a pause function too?
I would be thankful for every hints.
import UIKit
import SceneKit
import ARKit
class ViewController: UIViewController, ARSCNViewDelegate {
#IBOutlet var sceneView: ARSCNView!
override func viewDidLoad() {
super.viewDidLoad()
sceneView.delegate = self
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
let configuration = ARImageTrackingConfiguration()
if let trackedImages = ARReferenceImage.referenceImages(inGroupNamed: "AR Resources", bundle: Bundle.main) {
configuration.trackingImages = trackedImages
configuration.maximumNumberOfTrackedImages = 2
}
sceneView.session.run(configuration)
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
sceneView.session.pause()
}
func renderer(_ renderer: SCNSceneRenderer, nodeFor anchor: ARAnchor) -> SCNNode? {
let node = SCNNode()
if let imageAnchor = anchor as? ARImageAnchor {
let size = imageAnchor.referenceImage.physicalSize
var videoNode = SKVideoNode()
switch imageAnchor.name {
case "Image1":
videoNode = SKVideoNode(fileNamed: "Image1.mp4")
case "Image2":
videoNode = SKVideoNode(fileNamed: "Image2.mp4")
case "Image3":
videoNode = SKVideoNode(fileNamed: "Image3.mp4")
default:
break
}
videoNode.play()
let videoScene = SKScene(size: CGSize(width: 1280, height: 960))
videoScene.anchorPoint = CGPoint(x: 0.5, y: 0.5)
videoScene.addChild(videoNode)
let plane = SCNPlane(width: size.width, height: size.height)
plane.firstMaterial?.diffuse.contents = videoScene
let planeNode = SCNNode(geometry: plane)
plane.firstMaterial?.isDoubleSided = true
planeNode.eulerAngles.x = .pi / 2
node.addChildNode(planeNode)
return node
}
return nil

I'm trying to create blur effect on a view and than add a shape which will show image on this blurred layer (custom video editing functionality)
Currently I'm able to do it only dragging mask view from the right edge:
but when I try to do it from the left edge, I get such a effect:
func configureBlurView() {
let viewHeight: CGFloat = 60
let padding: CGFloat = 10
blurView = UIView()
blurView.layer.cornerRadius = 10
blurView.clipsToBounds = true
blurView.isHidden = true
blurView.translatesAutoresizingMaskIntoConstraints = false
addSubview(blurView)
addConstraints([
blurView.leadingAnchor.constraint(equalTo: leadingAnchor, constant: padding),
blurView.bottomAnchor.constraint(equalTo: stackView.topAnchor, constant: -padding),
blurView.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -padding),
blurView.heightAnchor.constraint(equalToConstant: viewHeight)
])
addBlurEffect(for: blurView)
}
private func addBlurEffect(for view: UIView) {
let blurEffect = UIVisualEffectView(effect: UIBlurEffect(style: .dark))
blurEffect.alpha = 0.5
blurEffect.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(blurEffect)
addConstraints([
blurEffect.topAnchor.constraint(equalTo: view.topAnchor),
blurEffect.leadingAnchor.constraint(equalTo: view.leadingAnchor),
blurEffect.bottomAnchor.constraint(equalTo: view.bottomAnchor),
blurEffect.trailingAnchor.constraint(equalTo: view.trailingAnchor)
])
}
private func makeClearHole(rect: CGRect) {
let maskLayer = CAShapeLayer()
maskLayer.fillColor = UIColor.black.cgColor
let pathToOverlay = CGMutablePath()
pathToOverlay.addRect(blurView.bounds)
pathToOverlay.addRect(rect)
maskLayer.path = pathToOverlay
maskLayer.fillRule = .evenOdd
maskLayer.cornerRadius = 10
blurView.layer.mask = maskLayer
}
I'm using touchesMoved method to change orange view dimensions:
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
guard trimmerView.isHidden == false else { return }
if let touch = touches.first{
let currentTouchPoint = touch.location(in: self)
let previousTouchPoint = touch.previousLocation(in: self)
let deltaX = currentTouchPoint.x - previousTouchPoint.x
if trimmerView.bounds.width >= 70 {
if touchStartEdge.middle {
if trimmerViewLeadingConstraint.constant < 10 {
trimmerViewLeadingConstraint.constant = 10
} else if trimmerViewTrailingConstraint.constant > -10 {
trimmerViewTrailingConstraint.constant = -10
} else {
trimmerViewLeadingConstraint.constant += deltaX
trimmerViewTrailingConstraint.constant += deltaX
}
}
if touchStartEdge.leftEdge {
if trimmerViewLeadingConstraint.constant >= 10.0 {
trimmerViewLeadingConstraint.constant += deltaX
} else if trimmerViewLeadingConstraint.constant < 10.0 {
trimmerViewLeadingConstraint.constant = 10
}
}
if touchStartEdge.rightEdge {
if trimmerViewTrailingConstraint.constant <= -10 {
trimmerViewTrailingConstraint.constant += deltaX
} else if trimmerViewTrailingConstraint.constant > -10 {
trimmerViewTrailingConstraint.constant = -10.0
}
}
}
updateProgressBarConstraints()
makeClearHole(rect: CGRect(x: 0, y: 0, width: trimmerView.frame.width, height: trimmerView.frame.height))
UIView.animate(withDuration: 0.10, delay: 0, options: .curveEaseIn) { [weak self] in
self?.layoutIfNeeded()
}
}
}
What I'd like to achieve is to remove blur effect only in bounds of orange view.
Any ideas ?? :)
Thanks for help!!
Couple ways to do this - here's one...
Add a mask to the blur effect view. As the user drags the "trimmer" update the mask.
Here's a quick example...
We'll:
create a stack view with 10 images
overlay that with a masked blur effective view
add a "draggable trimmer view"
when we drag the trimmer, we update the mask
Example View Controller
class TrimmerVC: UIViewController {
var blurView: MaskedBlurView!
let trimmerView = DragView()
let stackView = UIStackView()
override func viewDidLoad() {
super.viewDidLoad()
// respect safe area when we setup constraints
let g = view.safeAreaLayoutGuide
stackView.distribution = .fillEqually
stackView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(stackView)
NSLayoutConstraint.activate([
stackView.topAnchor.constraint(equalTo: g.topAnchor, constant: 40.0),
stackView.leadingAnchor.constraint(equalTo: g.leadingAnchor, constant: 40.0),
stackView.trailingAnchor.constraint(equalTo: g.trailingAnchor, constant: -40.0),
stackView.heightAnchor.constraint(equalToConstant: 80.0),
])
// let's add 10 imageviews to the stack view
for i in 1...10 {
if let img = UIImage(systemName: "\(i).circle.fill") {
let imgView = UIImageView(image: img)
imgView.backgroundColor = UIColor(white: 0.95, alpha: 1.0)
stackView.addArrangedSubview(imgView)
}
}
let blurEffect = UIBlurEffect(style: .dark)
blurView = MaskedBlurView(effect: blurEffect)
blurView.alpha = 0.5
blurView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(blurView)
NSLayoutConstraint.activate([
blurView.topAnchor.constraint(equalTo: stackView.topAnchor, constant: 0.0),
blurView.leadingAnchor.constraint(equalTo: stackView.leadingAnchor, constant: 0.0),
blurView.trailingAnchor.constraint(equalTo: stackView.trailingAnchor, constant: 0.0),
blurView.bottomAnchor.constraint(equalTo: stackView.bottomAnchor, constant: 0.0),
])
trimmerView.backgroundColor = .systemOrange
view.addSubview(trimmerView)
trimmerView.didDrag = { [weak self] newX in
guard let self = self else { return }
self.blurView.clearX = newX - self.stackView.frame.origin.x
}
}
// we'll use this to update the framing when the stack view width changes
// such as on device rotation
var curStackW: CGFloat = -1
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
if curStackW != stackView.frame.width {
curStackW = stackView.frame.width
var r = stackView.frame
r.origin.y += r.size.height + 20.0
r.size.width = 160
r.size.height = 40
trimmerView.frame = r
blurView.clearWidth = trimmerView.frame.width
blurView.clearX = 0
}
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
// toggle the trimmer view between
// below the stack view and
// overlaid on the stack view
if trimmerView.frame.origin.y > stackView.frame.origin.y {
let r = stackView.frame
trimmerView.frame.origin.y = r.origin.y - 6.0
trimmerView.frame.size.height = r.height + 12.0
} else {
let r = stackView.frame
trimmerView.frame.origin.y = r.origin.y + r.height + 12.0
trimmerView.frame.size.height = 60.0
}
}
}
Example Draggable "Trimmer" View
class DragView: UIView {
var didDrag: ((CGFloat) -> ())?
let maskLayer = CAShapeLayer()
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
commonInit()
}
func commonInit() {
maskLayer.fillColor = UIColor.red.cgColor
layer.mask = maskLayer
}
override func layoutSubviews() {
super.layoutSubviews()
let pathToOverlay = CGMutablePath()
pathToOverlay.addRect(bounds)
pathToOverlay.addRect(bounds.insetBy(dx: 20.0, dy: 8.0))
maskLayer.path = pathToOverlay
maskLayer.fillRule = .evenOdd
maskLayer.cornerRadius = 10
}
var touchStartX: CGFloat = 0
var frameStartX: CGFloat = 0
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
guard let touch = touches.first else { return }
touchStartX = touch.location(in: self.superview!).x
frameStartX = self.frame.origin.x
}
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
guard let touch = touches.first else { return }
let loc = touch.location(in: self.superview!)
self.frame.origin.x = frameStartX + (loc.x - touchStartX)
didDrag?(self.frame.origin.x)
}
}
Example Masked Blur View
class MaskedBlurView: UIVisualEffectView {
public var clearWidth: CGFloat = 100 {
didSet { updateMask() }
}
public var clearX: CGFloat = 0 {
didSet { updateMask() }
}
private let maskLayer = CAShapeLayer()
override init(effect: UIVisualEffect?) {
super.init(effect: effect)
commonInit()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
commonInit()
}
func commonInit() {
maskLayer.fillColor = UIColor.red.cgColor
layer.mask = maskLayer
}
func updateMask() {
let leftR = CGRect(x: 0, y: 0, width: clearX, height: bounds.height)
let rightR = CGRect(x: clearX + clearWidth, y: 0, width: bounds.width, height: bounds.height)
let bez = UIBezierPath(rect: leftR)
bez.append(UIBezierPath(rect: rightR))
maskLayer.path = bez.cgPath
}
override func layoutSubviews() {
super.layoutSubviews()
maskLayer.frame = bounds
}
}
When running (in landscape orientation) it will start like this:
I placed the "trimmer" view below the stack view to make it a little more clear what's happening.
As we drag the trimmer view, the blur view's mask will be updated:
Tapping anywhere in an empty part of the screen will toggle the trimmer view between "under the stack view" and "overlaid on the stack view":
This was just put together quickly -- you should have no trouble restructuring the code to wrap everything into a single custom view (or however it would work best for your needs).
I am learning swift and trying to pass a variable to a sheet but it isn't changing the variable when the sheet pops up, is there a different way to do this?
let bottomSheet = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "bottomSheet")
if let sheet = bottomSheet.sheetPresentationController{
sheet.detents = [.medium()]
sheet.prefersGrabberVisible = true
sheet.preferredCornerRadius = 24
sheet.prefersGrabberVisible = true
}
bottomSheet.isEnabled = true
self.present(bottomSheet, animated: true, completion: nil)
And in the bottomSheet view controller I have the variable
var isEnabled: Bool = false
But even though I put true it always shows as false
Try it like this, what you need to do is specify it as a view controller.
let mainStoryboard = UIStoryboard(name: "Main", bundle: nil)
if let bottomSheet = mainStoryboard.instantiateViewController(withIdentifier: "bottomSheet") as? BottomSheetVC{
if let sheet = bottomSheet.sheetPresentationController{
sheet.detents = [.medium()]
sheet.prefersGrabberVisible = true
sheet.preferredCornerRadius = 24
sheet.prefersGrabberVisible = true
}
bottomSheet.isEnabled = true
self.present(bottomSheet, animated: true)
}
sheetPresentationController only work for ios 15 and later, for previously versions you need to set .custom modalPresentationStype
controller.modalPresentationStyle = .pageSheet
if #available(iOS 15.0, *) {
if let sheet = controller.sheetPresentationController {
sheet.detents = [.medium()]
}
} else {
controller.modalPresentationStyle = .custom
controller.transitioningDelegate = self
}
self.present(controller, animated: true, completion: nil)
// MARK: - UIViewControllerTransitioningDelegate
extension CPPdfPreviewVC: UIViewControllerTransitioningDelegate {
func presentationController(forPresented presented: UIViewController, presenting: UIViewController?, source: UIViewController) -> UIPresentationController? {
PresentationController(presentedViewController: presented, presenting: presenting)
}
and Add Presentation controller as given

I made a parallax background, in GameScene.sks I added an empty node, added two sprites to an empty node. I have a reset button, when I click on it I need the background to be removed and added to its position (restarted), but when I add in scrollBg.removeAllChildren restart function I error occurs, how do I properly add and remove children from the scene ?

I have 2 files that I imported from Blender(3D design program) they are both .dae specifically they are "CampusField1.dae" CampusField is the ground/floor of the game and "Bob.dae" is the Man/character. My question is when I set CampusField1 as the scene how do I get "Bob" in the scene too. And the other question is lets say I export the .dae from blender now I put the file in the game... every things good but then is the animation for Bob already attached to the Bob.dae file or do I have to export something else from blender so that I can run the animation because I don't know what the animation ID would be or how to actually make it run and to actually make Bob do something.

The first thing to tell you is you have got two SCNScene; CampusField and Bob. Therefore you need to take out the character node from the Bob scene.
You need to name the node as like from the above figure. And extract that node from the scene as:
let bobScene = SCNScene(named: "Bob.dae")
let bobNode = personScene?.rootNode.childNodeWithName("person", recursively: true)
let campusFieldScene = SCNScene(named: "CampusField1.dae")
campusFieldScene.rootNode.addChildNode(bobNode)
