Start with the QHoops app in the Starter folder. This is Vision Pro project like before, minus the boilerplate scene. Once again, you’ll use the Show Immersion toggle to load and reset the scene.

Toggle("Show ImmersiveSpace", systemImage: "mountain.2", isOn: $showImmersiveSpace)

let floor = ModelEntity(mesh: .generatePlane(width: 100, depth: 100), materials: [OcclusionMaterial()])
floor.generateCollisionShapes(recursive: false)
floor.components[PhysicsBodyComponent.self] = .init(
  massProperties: .default,
  mode: .static
)
content.add(floor)

var dragGesture: some Gesture {
  DragGesture()
    .targetedToAnyEntity()
    .onChanged { value in
      value.entity.position = value.convert(value.location3D, from: .local, to: value.entity.parent!)
      value.entity.components[PhysicsBodyComponent.self]?.mode = .kinematic
    }
}

.gesture(dragGesture)
