class ViewController: UIViewController {
    
    @IBOutlet var arView: ARView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Load the "Box" scene from the "Experience" Reality File
        let boxAnchor = try! Experience.loadBox()
        boxAnchor.actions.tapped.onAction=clickEvent(_:)
        // Add the box anchor to the scene
        arView.scene.anchors.append(boxAnchor)
    }
    
    func clickEvent(_ entity: Entity?) {
        guard let entity = entity else { return }
        
        print(entity.name)
    }
}
