RealityKit – 以编程方式设置 Reality Composer 实体的文本

Bla*_*ock 5 augmented-reality swift arkit realitykit reality-composer

在我的 iOS 应用程序中,我想使用新的 Reality Composer 引入 AR 的一部分。

在我的项目中,我使用以下代码加载场景:

let arView = ARView.init(frame: frame)

// Configure the AR session for horizontal plane tracking.

let arConfiguration = ARWorldTrackingConfiguration()
arConfiguration.planeDetection = .horizontal
arView.session.run(arConfiguration)
arView.session.delegate = self

self.view.addSubview(arView)

Experience.loadSceneAsync{ [weak self] scene, error in

print("Error \(String(describing: error))")

guard let scene = scene else { return }

arView.scene.addAnchor(scene)

// THIS IS THE entity that i want to edit programmatically
scene.Label

“scene.label”在我的场景中的文本对象,我想设置文本编程。

我怎样才能做到这一点?这是可能的?

在 RealityKit 框架中,使用以下类型方法生成 3D 文本:

static func generateText(_ string: String, 
                   extrusionDepth: Float, 
                             font: MeshResource.Font, 
                   containerFrame: CGRect, 
                        alignment: CTTextAlignment, 
                    lineBreakMode: CTLineBreakMode) -> MeshResource

让我们看看真正的代码是怎样的:

let textAnchor = try! SomeText.loadTextScene()

let textEntity: Entity = textAnchor.vacation!.children[0].children[0]

var textModelComponent: ModelComponent = (textEntity.components[ModelComponent])!

textModelComponent.mesh = .generateText("Hello, World!",
                         extrusionDepth: 0.5,
                                   font: .systemFont(ofSize: 0.25),
                         containerFrame: CGRect.zero,
                              alignment: .center,
                          lineBreakMode: .byCharWrapping)

textAnchor.vacation!.children[0].children[0].components.set(textModelComponent)
arView.scene.anchors.append(textAnchor)
