Can you access the objects in a struct from outside the struct?
So far I have a group of HStacks and VStacks whose embedded objects are all Images(“name”).
By definition these Images are fixed in terms of their .position and .size for example.
Can I dynamically access these embedded objects from outside the struct?
in short, move them ?

Where do I place my code to instantiate my Project’s struct code within SwiftUI?
As you can see way below, I call:
_ = StaticObjects()
Within GameScene’s didMove
It seems the reason I don’t see the same #Preview image in my GameScene is that I am not explicitly returning a SwiftUI some View within my struct layout.
I do know that didMove is really called .. but I just don’t see anything within the Simulator
My #Preview works great:
The following code appears within GameScene.swift of my Xcode Project:
import SpriteKit
import SwiftUI
struct StaticObjects : View {
// some View is returned when our struct is instantiated
var body: some View {
let theBuildings = ["hotel",
"saloon",
"watertower",
"jail",
"farmhouse",
"barn"]
let theFigures = ["desperado",
"sheriff",
"space",
"space",
"horse",
"guy"]
VStack {
HStack(alignment: .bottom) {
ForEach(theBuildings, id: \.self) { theBuilding in
Image(theBuilding)
.resizable() // for rotation
.scaledToFit()
.zIndex(2)
Spacer()
} // ForEach
} // HStack for theBuildings
HStack(alignment: .bottom) {
ForEach(theFigures, id: \.self) { theFigure in
Image(theFigure)
.resizable() // for rotation
.frame(width: 120, height: 230)
.offset(x: 0.0, y: -50.0)
.zIndex(2)
Spacer()
} // ForEach
} // HStack for theFigures
// aligns vertically the entire struct to the top
Spacer()
} // VStack
} // body:
} // struct StaticObjects
/*
#Preview {
StaticObjects()
}
*/
class GameScene: SKScene, SKPhysicsContactDelegate {
override func sceneDidLoad() {
super.sceneDidLoad()
} // sceneDidLoad
override func didMove(to view: SKView) {
super.didMove(to:view)
physicsWorld.contactDelegate = self
_ = StaticObjects() // doesn’t work
} // didMove
func didBegin(_ contact: SKPhysicsContact) {
// ...
} // didBegin
} // class GameScene

12.9 inch iPad Simulator not presenting SpriteNodes correctly for Xcode
When I generate my SKScene, I use
ourScene.scaleMode = .aspectFill
I then display several SKShapeNodes, e.g.,
let roomWidth = UIScreen.main.bounds.width
let roomHeight = UIScreen.main.bounds.height
let circleRadius = 30.0
itsStatusNode = SKShapeNode(circleOfRadius: circleRadius)
let circleOffsetX = 95.0
let circleOffsetY = 70.0
let circlePosX = roomWidth/2 - circleRadius - circleOffsetX
let circlePosY = roomHeight/2 - circleRadius - circleOffsetY
itsStatusNode.position = CGPoint(x: circlePosX, y: circlePosY)
toScene.addChild(itsStatusNode)
The above Code works for all Xcode Simulators:
iPad (10th Generation)
iPad Air (5th Generation)
iPad Pro (11 inch) (4th Generation)
iPad Mini (6th Generation)
except the iPad (12.9 inch )(6th Generation)
For example, these work for all except the 12.9"
(landscape)
circleOffsetX = 95.0
circleOffsetY = 70.0
(portrait)
circleOffsetX = 70.0
circleOffsetY = 95.0
For just the 12.9" these work
(landscape)
circleOffsetX = 190.0
circleOffsetY = 145.0
(portrait)
circleOffsetX = 150.0
circleOffsetY = 190.0
I have seen other reports that point other errors out for just the 12.9 inch Simulator.
Or, is this one of many examples when I have to upload the App to a real Device such as my iPad or Apple TV?
FWIW, I only have a iPad Mini, not the 12.9 inch version
As always, thanks bunches for just reading this.
Error = Device orientations are not supported in Mac Catalyst processes
Got this error when selecting the Destination = "My Mac (designed for iPad".
I tried using the following Code Snippet in my GameViewController, but it did not work. Can anyone provide some guidance?:
#if os(iOS) && !targetEnvironment(macCatalyst)
// for rotation Landscape <-> Portrait = iOS,
// but *not* for Mac (built for iPad)
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
showScene()
} // viewDidLayoutSubviews

Cannot look at contents of file in Print Queue with Sonoma
Before Sonoma, after I selected print in a application, e.g., Word, I could double click on the document stored in the Print Queue and the pages would be displayed.
With Sonoma, cannot see file contents??
One last thing pertaining to this Print Queue =
I can't delete any of the accumulated "Completed" Jobs .. menu item to delete selected Jobs is dimmed??
New after update to Xcode 15:
Error processing request from MAD on result: Error Domain=NSOSStatusErrorDomain Code=-128 "Request was canceled"
Here is my code which I call within my GameViewController's viewDidLoad().
present(itsPlayerController!, animated:true) {
self.itsMoviePlayer?.play()
self.itsMovieIsFinished = false
}
Here is my code which I call at various times via playMovie(movieName: "pose"):
func playMovie(movieName: String) {
NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
object: itsPlayerController?.player?.currentItem)
present(itsPlayerController!, animated:true) {
self.itsMoviePlayer?.play()
self.itsMovieIsFinished = false
}
} // playMovie
@objc func playerDidFinishPlaying(note: NSNotification) {
self.itsPlayerController?.dismiss(animated:false, completion:nil)
nextScene()
changeScene()
// re-init for next time
setupMovie(theMovieName: "pose")
}
NB:
If I do not call playMovie ==> NO ERROR
THE PROBLEM = my call to present within playMovie. If I totally comment out present, = NO ERROR
If I comment out just the guts of present, other errors are introduced.
I have checked the syntax of calling present and I don't see any error there.
All the above pertains to the Destination = iPad Mini (6th Generation
If the Destination = Apple TV, then we get within GameViewDidLoad
Unable to simultaneously satisfy constraints.
For both Destinations, the Game runs OK - it's just these Warnings??

Too Complex to Compile?
Ventura 13.4.1
New error after update to Xcode 14.3.1 from 14.3.0
// ... <= -(roomHeight/2 - kFudge) too complex to compile ??
if (playerPosY - playerHeight/2) <= (kFudge - roomHeight/2)
{
// ... this variation works, the previous one doesn't
}
kFudge and the other parms are declared Double! within AppDelegate.
I don't understand what is suddenly wrong after Xcode update.

I have multiple images that at various times I need to replace a target image for a SKSpriteNode.
Each of these multiple images has a different size.
The target SKSpriteNode has a fixed frame that I want to stay fixed.
This target is created via:
myTarget = SKSpriteNode(imageNamed: “target”)
myTarget.size = CGSize(…)
myTarget.physicsBody = SKPhysicsBody(rectangleOf: myTarget.size)
How do I resize each of the multiple images so that each fills up the target frame (expand or contract)?
Pretend the target is a shoebox and each image is a balloon that expands or contracts to fill the shoebox.
I have tried the following that fails, that is, it changes the size of the target to fit the new image .. in short, it does the exact opposite of what I want.
let newTexture = SKTexture(imageNamed: newImage)
let changeImgAction = SKAction.setTexture(newTexture, resize: true)
myTarget.run(changeImgAction)
Again, keep frame of myTarget fixed and change size of newTexture to fit the above frame ..
Just submitted version update to my existing app. Exactly how long before App Connect shows Waiting for Review
Nimbus+ game controller not working with Ventura 13.3 and comparable tvOS
Prior to updating these OS' yesterday, my Computer App in the App Store worked.
After updating, not working.
I have contacted SteelSeries, the mgr of Nimbus+, and they refuse to admit it's their firmware.
And I have definitely started up their SteelSeries CG application and looked for a firmware update -- none.
Replacement of hardware is not the solution.
Any contrary ideas you folk may have would be extremely helpful.
Specifically the Nimbus+ ... but I tried for a few days a PlayStation Dual Sense ... and the identical problem with just Mac OS Ventura 13.3.
One more thing, ZERO problems with my iPhone and your Apple TV. So, the following problem is ONLY with Ventura 13.3 (NOT 13.2 and earlier - just 13.3).
Here's the problem .. the Nimbus+ will not stay connected and after about 15 seconds disconnects by itself.
The above PlayStation Dual Sense sticks around for about 60 seconds and then disconnects by itself.
For the record, I have several times chatted with Nimbus Tech Support. Total Failure, sorry to say.
Some chatter out there in Google Land said that the blinking lights on my Nimbus+ show (to him) that the chargeable batteries are "bricked" and need to be reset. If true, then why does my Nimbus+ work great with my iPhone and Apple TV? Just asking ...
I'm a computer programmer but I am not a hardware person who can take apart the Nimbus and hit its reset button.
There you have it ... any help at all will be appreciated.

Using Swift, how do I continuously test for a GamePad being on/connected?
When you build a Browser-based Canvas + Javascript Game, you do the above via:
function listenForGamepadConnected() {
window.addEventListener("gamepadconnected", (event) => {
// this is the BIGEE that is always testing
});
} // listenForGamepadConnected
And it definitely works!
I cannot find its equivalent in the Xcode/Swift world?
I do see the following that’s built into a boilerplate Game that you initially create using Xcode - but it seems that it just looks once, versus continuously:
func ObserveForGameControllers() {
NotificationCenter.default.addObserver(
self,
selector: #selector(connectControllers),
name: NSNotification.Name.GCControllerDidConnect,
object: nil)
NotificationCenter.default.addObserver(
self,
selector: #selector(disconnectControllers),
name: NSNotification.Name.GCControllerDidDisconnect,
object: nil)
} // ObserveForGameControllers
@objc func connectControllers() {
// Unpause the Game if it is currently paused
self.isPaused = false
// Used to register the Nimbus Controllers to a specific Player Number
var indexNumber = 0
// Run through each controller currently connected to the system
for controller in GCController.controllers() {
// Check to see whether it is an extended Game Controller (Such as a Nimbus)
if controller.extendedGamepad != nil {
print("CONNECTED - Extended Gamepad #\(indexNumber)")
controller.playerIndex = GCControllerPlayerIndex.init(rawValue: indexNumber)!
indexNumber += 1
setupControllerControls(controller: controller)
}
else {
print("CONNECTED - but, NOT an Extended Gamepad #\(indexNumber)")
}
}
} // connectControllers
@objc func disconnectControllers() {
print("DIS-CONNECTED")
// Pause the Game if a controller is disconnected ~ This is mandated by Apple
self.isPaused = true
} // disconnectControllers
I try to call it in a Timer loop, but still does not work:
@objc func testForGamepadIsConnected() {
ObserveForGameControllers
var gamepadOn = !self.isPaused // does not work
} // testForGamepadIsConnected
func startTestForGamepad() {
guard (gamepadTimer != nil) else {
gamepadTimer = Timer.scheduledTimer(
timeInterval: 1.0,
target: self,
selector:#selector(testForGamepadIsConnected),
userInfo: nil,
repeats: true)
return
}
} // startTestForGamepad
func stopTestForGamepad() {
guard (gamepadTimer == nil) else {
gamepadTimer!.invalidate()
// .invalidate() removes Timer() from gamepadTimer, so reinitialize it.
gamepadTimer = Timer()
return
}
} // stopTestForGamepad
Scoured the Google world, but I’ve come up empty.
Would appreciate some genius out there providing what I’m missing.
Thanks loads.

With Xcode 14.2, had trouble pairing with my Apple TV (latest update). It continuously showed "Not Connected".
So, I unpaired my apple tv and now the ATV does not show under Devices and Simulators.
My ATV shows as the Target of my Xcode Project
My Ventura 13.3 iMac mirrors to my ATV just great, but not my Xcode 14.2.
Have turned off my ATV, quit Xcode and Shutdown and then re-started my iMac and no luck.
Help desperately needed.
Other posts seem to show an identical problem experienced by others.

Trouble making SKSpriteNode bounce off anotherSKSpriteNode using Bit Masks and func didBegin(..)
Here are some brief Code Snippets:
For brevity, let's consider 4 SKSpriteNode's
The Bit Masks and the .png Strings are defined within AppDelegate, along with:
var noCollision: UInt32 = 00000000
var noContact: UInt32 = 00000000
var roomCategory: UInt32 = 00000001
var playerCategory: UInt32 = 00000010
var ballCategory: UInt32 = 00000100
var UCategory: UInt32 = 00001000
Next Snippet appears within GameViewController which calls .addChild for each Node:
myRoom = SKSpriteNode(imageNamed: "room.png")
myRoom.size = CGSize(width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height)
myRoom.physicsBody = SKPhysicsBody(rectangleOf: myRoom.size)
myRoom.physicsBody?.categoryBitMask = roomCategory
myRoom.physicsBody?.contactTestBitMask = noContact
myPlayer = SKSpriteNode(imageNamed: "player.png")
myPlayer.size = CGSize(width: playerWidth, height: playerHeight)
myPlayer.physicsBody = SKPhysicsBody(rectangleOf: myPlayer.size)
myPlayer.physicsBody?.categoryBitMask = playerCategory
myPlayer.physicsBody?.collisionBitMask = noCollision
myPlayer.physicsBody?.contactTestBitMask = noContact
myBall = SKSpriteNode(imageNamed: "ball.png")
myBall.size = CGSize(width: ballWidth, height: ballHeight)
myBall.physicsBody = SKPhysicsBody(rectangleOf: myBall.size)
myBall.physicsBody?.categoryBitMask = ballCategory
myBall.physicsBody?.collisionBitMask = noCollision
myBall.physicsBody?.contactTestBitMask = roomCategory | UCategory
myUStake = SKSpriteNode(imageNamed: "ustake.png")
myUStake.size = CGSize(width: U1Width, height: U1Height)
myUStake.physicsBody = SKPhysicsBody(rectangleOf: myU1.size)
myUStake.physicsBody?.categoryBitMask = UCategory
myUStake.physicsBody?.collisionBitMask = noCollision
myUStake.physicsBody?.contactTestBitMask = ballCategory
Finally, here's my func didBegin
func didBegin(_ contact: SKPhysicsContact) {
let bodyAName = contact.bodyA.node?.name
let bodyBName = contact.bodyB.node?.name
let playerHitBall = ((bodyBName == myPlayer.name) && (bodyAName == myBall.name)) ||
((bodyAName == myPlayer.name) && (bodyBName == myBall.name))
let ballHitU = ((bodyBName == myBall.name) && (bodyAName == myU1.name)) ||
((bodyAName == myBall.name) && (bodyBName == myU1.name))
if playerHitBall {
// moveBallIfHitsWall()
// attaBoy()
print("player hit ball")
}
if ballHitU {
// attaBoy()
// moveBallIfHitsUStake(theUStake: UStakes[0])
print("ball hit U1")
}
} // didBegin
No print statements show in the Debugger.
Anybody that has some light to shine on my error or errors would be greatly appreciated.
Thanks in advance.
