Swift 在RealityKit中添加场景覆盖

在ARKit中，我们可以轻松地添加场景覆盖作为HUD（平视显示器）

---

你是如何在现实中做到这一点的？由于ARView中没有overlaySKScene？

您可以通过编程方式创建此覆盖：

import SpriteKit
import RealityKit

class ViewController: UIViewController {

    @IBOutlet var arView: ARView!
    let skView = SKView(frame: CGRect(x: 0, y: 0, width: 200, height: 150))
    let scene = SKScene()

    override func viewDidLoad() {
        super.viewDidLoad()

        arView.backgroundColor = .black
        skView.showsFPS = true
        scene.backgroundColor = .systemTeal

        let boxAnchor = try! Experience.loadBox()
        boxAnchor.steelBox?.scale = [9,9,9]
        arView.scene.anchors.append(boxAnchor)

        arView.addSubview(skView)
        skView.presentScene(scene)
    }
}

import SpriteKit
import RealityKit

class ViewController: UIViewController {

    @IBOutlet var arView: ARView!
    let skView = SKView(frame: CGRect(x: 0, y: 0, width: 200, height: 150))
    let scene = SKScene()

    override func viewDidLoad() {
        super.viewDidLoad()

        arView.backgroundColor = .black
        skView.showsFPS = true
        scene.backgroundColor = .systemTeal

        let boxAnchor = try! Experience.loadBox()
        boxAnchor.steelBox?.scale = [9,9,9]
        arView.scene.anchors.append(boxAnchor)

        arView.addSubview(skView)
        skView.presentScene(scene)
    }
}
