Question

我真的很沮丧，我一直试图让它工作近两整天:(

如何在swift

中向SKSpriteNode添加点击事件

  let InstantReplay:SKSpriteNode = SKSpriteNode(imageNamed: "InstantReplay")
  InstantReplay.position = CGPoint(x: size.width + InstantReplay.size.width/2, y: size.height/2)
  InstantReplay.size = CGSize(width: size.width/1.4, height: size.height/8)
  addChild(InstantReplay)

  InstantReplay.runAction(SKAction.moveToX(size.width/2, duration: NSTimeInterval(1)))

我想要发生的是当点击“InstantReplay”以运行名为“InstantReplay_Clicked”的功能时，我将如何实现这一目标？

任何帮助非常感谢：）

为您的SKSpriteNode命名，以便我们可以在您的SKScene的touchesBegan或touchesEnded方法中识别它。

同时将SKSpriteNode的userInteractionEnabled设置为false，这样它就不会为自己捕获触摸事件，也不会将它们传递给场景。

override init() {
    super.init()

    let instantReplay = SKSpriteNode(imageNamed: "InstantReplay")
    instantReplay.position = CGPoint(x: size.width + instantReplay.size.width/2, y: size.height/2)
    instantReplay.size = CGSize(width: size.width/1.4, height: size.height/8)
    instantReplay.name = "InstantReplay"; // set the name for your sprite
    instantReplay.userInteractionEnabled = false; // userInteractionEnabled should be disabled
    self.addChild(instantReplay)
}

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
    let location = touches.anyObject()?.locationInNode(self)
    let node = self.nodeAtPoint(location!)
    if (node.name == "InstantReplay") {
        println("you hit me with your best shot!")
    }
}

（哦 - 我还将你的instantReplay变量重命名为使用lowerCamelCase，与Swift best practices一致。

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
  for t in touches {
    let node = self.atPoint(t.location(in :self))
    if (node.name == "InstantReplay") {
        print("you hit me with your best shot!")
    }
  }

}
