I realize the code snippet can be better formatted, so here's a better way to look at it struct GearRealityView: View { static var modelEntity = Entity() var body: some View { RealityView { content in if let model = try? await Entity(named: "LandingGear", in: realityKitContentBundle) { GearRealityView.modelEntity = model content.add(model) } } .gesture( DragGesture() .targetedToEntity(GearRealityView.modelEntity) .onChanged({ value in GearRealityView.modelEntity.position = value.convert(value.location3D, from: .local, to: GearRealityView.modelEntity.parent!) }) ) } }

Additionally, can this even be done? I tracked an object (using the anchoring method and the target being the reference object), then spawn a digital arrow on this tracked object. Now I draw collision boxes around these spawned digital arrows - can I check for collisions between 2 such arrows that are spawned based on 2 different objects being tracked? I read earlier that anchored objects have a different coordinate and physical space, so I'm now questioning if this is the right way to check this. Any suggestions would be very helpful! Thank you

So this is what I have as my SwiftUI code at the moment import SwiftUI import RealityKit import RealityKitContent struct DualObjectTrackingTest: View { @State private var subs: [EventSubscription] = [] var body: some View { RealityView { content in if let immersiveContentEntity = try? await Entity(named: "SceneFind.usda", in: realityKitContentBundle) { content.add(immersiveContentEntity) print("Collision check started") } } update: { content in //if let cube = content.entities.first?.findEntity(named: "WhiteArrow") as? ModelEntity { let event = content.subscribe(to: CollisionEvents.Began.self) { collisionEvent in print("Collision has occured") } DispatchQueue.main.async { subs.append(event) } } } } How do I change the physics components of the entities that are in the scene that I am loading? I have 2 anchor components added to 2 transforms in my scene - Transform1 and Transform2. Both of these transforms have an anchoring component each with the target being set to a reference object anchor that I am using. I don't see any properties that I can configure inside Reality Composer Pro, so if I need to reach these particular transforms that have the anchoring components, how do I do that from inside my code? It might be a very rudimentary question, but I'm learning swiftUI as I go so some guidance here would be very helpful! Thank you again

Apologies for the multiple comments, I have now been able to fix the physics simulation issue. I'm now adding collision boxes and physics body components to the 2 entities that I am spawning on my 2 object anchors, and trying to detect a collision between the two when I place the 2 objects on top of each other. Does not seem to be working at the moment. Any advice on what I can do for this? This is the code below that I'm using struct DualObjectTrackingTest: View { @State private var subs: [EventSubscription] = [] var body: some View { RealityView { content in if let immersiveContentEntity = try? await Entity(named: "SceneFind.usda", in: realityKitContentBundle) { content.add(immersiveContentEntity) print("Collision check started") if let Anchor1 = immersiveContentEntity.findEntity(named: "Object1"), var transform1 = Anchor1.components[AnchoringComponent.self], let Anchor2 = immersiveContentEntity.findEntity(named: "Object2"), var transform2 = Anchor2.components[AnchoringComponent.self] { transform1.physicsSimulation = .none transform2.physicsSimulation = .none } } } update: { content in let event = content.subscribe(to: CollisionEvents.Began.self) { collisionEvent in print("Collision HAS OCCURED!") } DispatchQueue.main.async { subs.append(event) } } } } I don't see any console logs indicating that the collision has occurred, even though the entities and their components (collision boxes) should technically be in the same coordinate and physical space..
