Swift Sprite Kit开始触摸功能

概述我正在搞乱一个 xcode项目,当我触摸它时,我正试图让一个红色的球SKShapeNode四处移动.触摸我自己的源代码开始上课并没有做到.我的代码有什么缺陷,我需要做些什么来修复它. import SpriteKitclass GameScene: SKScene { //Rectangle Skeletions var leftWallRect = CGRect(x: 0, 我正在搞乱一个 xcode项目,当我触摸它时,我正试图让一个红色的球SKShapeNode四处移动.触摸我自己的源代码开始上课并没有做到.我的代码有什么缺陷,我需要做些什么来修复它.

import SpriteKitclass GameScene: SKScene {    //Rectangle Skeletions    var leftWallRect = CGRect(x: 0,y: 0,wIDth: 40,height: 1000)    var ball = SKShapeNode(circleOfRadius: 25);    overrIDe func dIDMovetoVIEw(vIEw: SKVIEw) {        // Declare the Sprites in your scene        var ball = SKShapeNode(circleOfRadius: 25);        let leftWall = SKShapeNode(rect: leftWallRect);        let rightWall = SKShapeNode(rect: leftWallRect);        let pin = SKSpriteNode(imagenamed: "pin");        // Ball PropertIEs        ball.strokecolor = UIcolor.blackcolor()        ball.fillcolor = UIcolor.redcolor()        ball.position = CGPointMake(self.frame.wIDth / 2,self.frame.height / 4 - 100 )        self.addChild(ball)        // left Wall PropertIEs        leftWall.fillcolor = UIcolor.purplecolor()        leftWall.strokecolor = UIcolor.blackcolor()        leftWall.position = CGPointMake(self.frame.size.wIDth / 3 - 45,self.frame.size.height / 2 - 400)        self.addChild(leftWall)        //Right Wall PropertIEs        rightWall.fillcolor = UIcolor.purplecolor()        rightWall.strokecolor = UIcolor.blackcolor()        rightWall.position = CGPointMake(self.frame.size.wIDth / 2 + 175,self.frame.size.height / 2 - 400)        self.addChild(rightWall)    }    overrIDe func touchesBegan(touches: Set<NSObject>,withEvent event: UIEvent) {        /* Called when a touch begins */        let touch = touches.first as! UItouch        let touchLocation = touch.locationInNode(self)        if touchLocation == ball.position{            ball.position = touchLocation            println("touches");        }    }    overrIDe func update(currentTime: CFTimeInterval) {        /* Called before each frame is rendered */    }}

解决方法 大笑哇,这是一个有趣的,如果touchLocation == ball.position我会留下深刻的印象,如果你可以击中你的球的确切像素位置.你想要的是这个：

let touch = touches.first as! UItouchlet touchLocation = touch.locationInNode(self)let touchednode = self.nodeAtPoint(touchLocation)if touchednode == ball{...

但就个人而言,我要做的是制作SKSpriteNode的子类,并在这个孩子的触摸程序中做你的球的触摸代码
