从SCNScene和overlaySKScene获取触摸事件的swiftscenekit问题

概述下午好,我正在试图弄清楚如何从SCNNode&来自SCNScene的SKSpriteNode与SKScene重叠. import UIKitimport SceneKitclass GameViewController: UIViewController {var scnView:SCNView!var scnScene:SCNScene!var sprite: spritekitHUD 下午好,我正在试图弄清楚如何从SCNNode&来自SCNScene的SKSpriteNode与SKScene重叠.

import UIKitimport SceneKitclass GameVIEwController: UIVIEwController {var scnVIEw:SCNVIEw!var scnScene:SCNScene!var sprite: spritekitHUD!var cameraNode: SCNNode!var shape: SCNNode!overrIDe func vIEwDIDLoad() {    super.vIEwDIDLoad()    setupScene()     }func setupScene() {    scnVIEw = self.vIEw as! SCNVIEw    scnVIEw.delegate = self    scnVIEw.allowsCameraControl = true    scnScene = SCNScene(named: "art.scnassets/scene.scn")    scnVIEw.scene = scnScene    sprite=spritekitHUD(size: self.vIEw.bounds.size,game: self)    scnVIEw.overlaySKScene=sprite    cameraNode = scnScene.rootNode.childNode(withname: "camera",recursively: true)!    shape=scnScene.rootNode.childNode(withname: "shape",recursively: true)    shape.name="ThreeDShape"    } overrIDe func touchesBegan(_ touches: Set<UItouch>,with event: UIEvent?){ let touch = touches.first! let location = touch.location(in: scnVIEw) let hitResults = scnVIEw.hitTest(location,options: nil) if let result = hitResults.first {      handletouchFor(node: result.node)     }  }func handletouchFor(node: SCNNode) {  if node.name == "ThreeDShape" {         print("SCNNode touched")    }  }}

这是我的Spritekit叠加场景

import Foundationimport SpriteKitclass spritekitHUD: SKScene{var game:GameVIEwController!var shapeNode: SKSpriteNode!init(size: CGSize,game: GameVIEwController){    super.init(size: size)    self.backgroundcolor = UIcolor.white    let Spritesize = size.wIDth/12    self.shapeNode= SKSpriteNode(imagenamed: "shapeNode")    self.shapeNode.size = CGSize(wIDth: Spritesize,height: Spritesize)    self.shapeNode.position = CGPoint(x: Spritesize + 8,y: Spritesize + 8)    self.shapeNode.name="test"    self.game=game    self.addChild(self.pauseNode)}required init?(coder aDecoder: NSCoder) {    super.init(coder: aDecoder)}overrIDe func touchesEnded(_ touches: Set<UItouch>,with event: UIEvent?) {    guard let touch=touches.first else{        return    }    let location=touch.location(in: self)    if self.atPoint(location).name=="test" {     print("Spritekit node pressed")    } }}

所以有了这个,我可以成功获得通知,我的spritenode已经触及我的overlaySKScene,但我无法弄清楚如何获得我的SCNode被触摸的通知.如果你不能有2个touchesbegan函数,有没有人有任何想法如何我同时处理2d事件的3D事件？

谢谢你的帮助！！

这是从Xcode的游戏模板中直接“解除”……

在vIEwDIDLoad中添加手势识别器：

// add a tap gesture recognizer       let tapGesture = UITapGestureRecognizer(target: self,action:             #selector(handleTap(_:)))        scnVIEw.addGestureRecognizer(tapGesture)    func handleTap(_ gestureRecognize: UIGestureRecognizer) {    // retrIEve the SCNVIEw    let scnVIEw = self.vIEw as! SCNVIEw    // check what nodes are tapped    let p = gestureRecognize.location(in: scnVIEw)    let hitResults = scnVIEw.hitTest(p,options: [:])    // check that we clicked on at least one object    if hitResults.count > 0 {        // retrIEved the first clicked object        let result: AnyObject = hitResults[0]        // result.node is the node that the user tapped on        // perform any actions you want on it    }}
