How can I reverse USDZ animation in realityKit

How can i play a USDZ entity animation in reverse? I have tried to put a negative value to the speed as I was doing in SceneKit to make the animation reverse play but it did not work. here is my code: import SwiftUI import RealityKit struct ImmersiveView: View { @State var entity = Entity() @State var openDoor: Bool = true var body: some View { RealityView { content in if let mainDoor = try? await Entity(named: "Door.usdz") { if let frame = mainDoor.findEntity(named: "DoorFrame") { frame.position = [0, 0, -8] frame.orientation = simd_quatf(angle: (270 * (.pi / 180)), axis: SIMD3(x: 1, y: 0, z: 0)) content.add(frame) entity = frame.findEntity(named: "Door")! entity.components.set(InputTargetComponent(allowedInputTypes: .indirect)) entity.components.set(HoverEffectComponent()) let entityModel = entity.children[0] entityModel.generateCollisionShapes(recursive: true) } } } .gesture( SpatialTapGesture() .targetedToEntity(entity) .onEnded { value in print(value) if openDoor == true { let animController = entity.playAnimation(entity.availableAnimations[0], transitionDuration: 0 , startsPaused: true) animController.speed = 1.0 animController.resume() openDoor = false } else { let animController = entity.playAnimation(entity.availableAnimations[0], transitionDuration: 0 , startsPaused: true) animController.speed = -1.0 // it does not work to reverse animController.resume() openDoor = true } } ) } } The Door should open with first click which is already happening and close with second click which is not happening as it does not reverse play the animation

A Game Controller For visionOS RealityView

Im searching for a simple swiftUI code that can move a cube in immersive space when I click the X button on Sony Playstation Game Controller, I did load a USD entity and connect the game controller but when it comes to get a simple click into the reality view to change position or rotate the entity it always not even accepted in codes. although I can control it with a finger or hand gestures, and yes I have closed the "Send Game Controller to device" in the simulator to make sure the controller would not effect the system but only effect in the game, here is a sample import SwiftUI import RealityKit import GameController struct ImmersiveView: View { @State var entity = ModelEntity() @State var z: Float = -4.0 var body: some View { RealityView { content in if let cube = try? await ModelEntity(named: "am.usdz") { entity = cube entity.generateCollisionShapes(recursive: true) entity.name = "Cube" entity.position = [0, 0, -4] entity.components.set(InputTargetComponent(allowedInputTypes: .indirect)) entity.components.set(HoverEffectComponent()) content.add(entity) } } .gesture( SpatialTapGesture() .targetedToEntity(entity) .onEnded { value in print(value) z -= 1.0 entity.position = [0, 0, z] } ) // What to do here to make game controller button X act as the gesture do } }

Xcode, Fold group of codes under certain method/ function with a simple click

I Have a multiple if else statements under another if else statements and I want to be able to fold all child statements under certain parent without have to fold each one separately cause its like 100's of them example: This Is Unfolded func example(v1: String, v2: Int, v3: Int) { if v1 == "Food" { if v2 == 2 && v3 == 7 { // Some Long Lines Codes } else if v2 == 2 && v3 == 33 { // Some Long Lines Codes } else if v2 == 44 && v3 == 72 { // Some Long Lines Codes } else if v2 == 12 && v3 == 7 { // Some Long Lines Codes } else if v2 == 102 && v3 == 97 { // Some Long Lines Codes } } } And I Wanted To Be Folded Like That With A Simple Click Not Fold It One By One func example(v1: String, v2: Int, v3: Int) { if v1 == "Food" { if v2 == 2 && v3 == 7 {...} else if v2 == 2 && v3 == 33 {...} else if v2 == 44 && v3 == 72 {...} else if v2 == 12 && v3 == 7 {...} else if v2 == 102 && v3 == 97 {...} } } Imaging like 100 lines of those else if conditions that i need to fold each one manually using CMD + Opt + <- or even using the arrow beside, I hope there is a fast and reliable shortcut or a click to help folding child codes or selected codes btw I know there is a cmd + opt + shift + <- to fold all but that's not helping cause when I unfold the function I would see all remains as it was before. I hope anyone could have a clue or if there is an ability to add a script function to do so.
