pass / share class with SpriteView GameScene from a SwiftUi View - class

Question

I am playing around with SpriteView, which works great. However I cannot figure out how to share a class with Spritekit GameScene,that is instantiated in one my views. Sharing my class with other views works like a charm. But how can I access my gameCenterManager class from spritekit's GameScene, how do I pass the class ? I don't have any clue how to do this. I considered making a global accessible class, but its not what I want.
The goal is to be able to send and receive data from inside GameScene to update players location and etc. But the matchmaking happens inside a SwiftUI View, which is also where the class is created.
The gameCenterManger class is created like so;
struct ContentView: View {
#StateObject var gameCenterManager = GameCenterManager()
var body: some View {
...
etc
the class is set up like so :
class GameCenterManager: NSObject, ObservableObject {
//lots of stuff going on
...
}
And is shared to the GameSceneView view that will create the SpriteView, like so :
Button("Show Sheet") {
self.showingSheet.toggle()
}
.buttonStyle(RoundedRectangleButtonStyle())
.buttonStyle(ShadowButtonStyle())
.fullScreenCover(isPresented: $showingSheet, content: { GameSceneView(gameCenterManager:self.gameCenterManager)})
Finally, inside my GameSceneView, the GameScene for SpriteView is configured.
struct GameSceneView: View {
var gameCenterManager: GameCenterManager
#Environment(\.presentationMode) var presentationMode
var scene: SKScene {
let scene = GameScene()
scene.size = CGSize(width: UIScreen.main.bounds.size.width , height: UIScreen.main.bounds.size.height)
scene.scaleMode = .fill
return scene
}
var body: some View {
Button("Dismiss") {
self.presentationMode.wrappedValue.dismiss()
}
Button("send data") {
gameCenterManager.increment()
}
SpriteView(scene: scene )
.frame(width: UIScreen.main.bounds.size.width, height: UIScreen.main.bounds.size.height - 200 )
.ignoresSafeArea()
.overlay(ImageOverlay(), alignment: .bottomTrailing)
}
}

Perhaps others are looking to do the same? Here below is the answer in code snippets
GameCenterManager is the class that I want to access across all views and SKScenes
In mainview:
#main
struct gameTestApp: App {
#StateObject var gameCenterManager = GameCenterManager()
var body: some Scene {
WindowGroup {
ContentView().environmentObject(gameCenterManager)
}
}
}
In Contentview view add :
#EnvironmentObject var gameCenterManager:GameCenterManager
And where I transition to GameSceneView inside Contentview, which will load my SKScene
Button("Show Sheet") {
self.showingSheet.toggle()
}
.buttonStyle(RoundedRectangleButtonStyle())
.buttonStyle(ShadowButtonStyle())
.fullScreenCover(isPresented: $showingSheet, content: { GameSceneView()})
Then in GameSceneView add:
#EnvironmentObject var gameCenterManager:GameCenterManager
and where we load SKScene:
var scene: SKScene {
let scene = GameScene()
scene.size = CGSize(width: UIScreen.main.bounds.size.width , height: UIScreen.main.bounds.size.height)
scene.scaleMode = .fill
scene.gameCenterManager = gameCenterManager
return scene
}
Then finally in GameScene itself add:
var gameCenterManager: GameCenterManager?
