我需要在我的锚点上附加一些东西。我试图在我的类的一个函数中做到这一点,但我在我的视图控制器中声明了这个锚。
这个锚在我的班上不被认可。我如何到达这个锚点?
视图控制器.swift:
import UIKit
import RealityKit
import Combine
class ViewController: UIViewController {
@IBOutlet var arView: ARView!
override func viewDidLoad() {
super.viewDidLoad()
let gameAnchor = AnchorEntity(plane: .horizontal)
arView.scene.addAnchor(gameAnchor)
//generate random width en distance
let randomDistance = Double.random(in: 0.07...0.25)
let randomWidth = Double.random(in: 0.01...0.05)
//make a new platform
let newPlatform = Platform(width: randomWidth, heigth: 0.1, depth: 0.05, distance: randomDistance)
newPlatform.makePlatform()
}
}
我的课:
import Foundation
import RealityKit
class Platform {
var width: Double = 0.05
var heigth: Double = 0.1
var depth: Double = 0.05
var distance: Double = 0.1
init(width: Double, heigth: Double, depth: Double, distance: Double) {
self.width = width
self.heigth = heigth
self.depth = depth
self.distance = distance
}
func makePlatform() {
let platformMesh = MeshResource.generateBox(width: Float(width), height: 0.1, depth: 0.05)
let platformMaterial = SimpleMaterial(color: .red, isMetallic: false)
let newPlatform = ModelEntity(mesh: platformMesh, materials: [platformMaterial])
newPlatform.position.x = Float(distance)
newPlatform.position.y = 0.05
//append it to my anchor
///gameAnchor.addChild(newPlatform)
}
}
