目前我正在研究具有复制 AR 对象功能的基于 AR 的项目，我遇到的问题是当我使用 .clone() 方法克隆 SCNNode ...它创建相同的实例并且当我更改重复的 SCNNode 的名称时，它更改所有节点的名称.. 我如何克隆具有不同名称、模型名称等属性的 SCNNode？

基本上我想要每个克隆的虚拟对象的特定属性来删除对象..

放置对象的代码

    func placeVirtualObject(_ virtualObject: VirtualObject) {
    guard let cameraTransform = session.currentFrame?.camera.transform,
        let focusSquarePosition = focusSquare.lastPosition else {
        statusViewController.showMessage("CANNOT PLACE OBJECT\nTry moving left or right.")
        return
    }
    Api.Params.selectedModel = virtualObject
    virtualObject.name = String(Api.Params.inputPreviewId)
    virtualObject.scale = SCNVector3Make(0.01, 0.01, 0.01)

    virtualObject.setPosition(focusSquarePosition, relativeTo: cameraTransform, smoothMovement: false)
    updateQueue.async {
        self.sceneView.scene.rootNode.addChildNode(virtualObject)
    }
}

用于复制节点

        func placeDuplicateVirtualObject(_ virtualObject: VirtualObject) {
        guard let cameraTransform = session.currentFrame?.camera.transform,
            let focusSquarePosition = focusSquare.lastPosition else {
            statusViewController.showMessage("CANNOT PLACE OBJECT\nTry moving left or right.")
            return
        }
        Api.Params.selectedModel = virtualObject
        let duplicate = virtualObject.clone()
        
        duplicate.name = String(Api.Params.inputPreviewId)
        
        duplicate.scale = SCNVector3Make(0.01, 0.01, 0.01)

        duplicate.setPosition(focusSquarePosition, relativeTo: cameraTransform, smoothMovement: false)
        updateQueue.async {
            self.sceneView.scene.rootNode.addChildNode(duplicate)
        }
    }
