Question

我有两个从Blender（3D设计程序）导入的文件，它们都是.dae，特别是它们是“CampusField1.dae”.CamponField是游戏的底层/地板，“Bob.dae”是人/角色。我的问题是当我将CampusField1设置为场景时，我如何在场景中获得“Bob”。另一个问题是让我说我从混合器中导出.dae现在我把文件放在游戏中......每件事都很好但是鲍勃的动画已经附加到Bob.dae文件或者我必须导出一些东西否则从搅拌机，以便我可以运行动画，因为我不知道动画ID是什么或如何实际使其运行，并实际让鲍勃做一些事情。

代码：

import UIKit
import QuartzCore
import SceneKit

class GameViewController: UIViewController {
override func viewDidLoad() {
    super.viewDidLoad()

    let scene = SCNScene(named: "art.scnassets/CampusField1.dae")!

    let src = SCNSceneSource(URL: yourSceneURL, options: nil)
    let node = src.entryWithIdentifier("Bob", withClass: SCNNode.self) as SCNNode
    let animation = node.entryWithIdentifier("yourAnimationID", withClass: CAAnimation.self) as CAAnimation

首先要告诉你的是你有两个SCNScene; CampusField和Bob。因此，您需要从Bob场景中取出角色节点。

您需要将节点命名为如上图所示。并从场景中提取该节点：

let bobScene = SCNScene(named: "Bob.dae") 
let bobNode = personScene?.rootNode.childNodeWithName("person", recursively: true) 
let campusFieldScene = SCNScene(named: "CampusField1.dae") 
campusFieldScene.rootNode.addChildNode(bobNode)
