快速单击 SKSprite 节点

Question

我对此感到非常沮丧，我已经尝试让它工作了将近整整两天:(

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)))

我想要发生的只是当单击“InstantReplay”以运行一个名为“InstantReplay_Clicked”的函数时，我将如何实现这个？

非常感谢任何帮助:)

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。

还将您的 SKSpriteNode 的 userInteractionEnabled 设置为 false，这样它就不会自己捕获触摸事件，也不会将它们传递给您的场景。

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 - 我还重命名了您的 instantReplay 变量以使用 lowerCamelCase，符合 Swift best practices。

Swift 4 更新

override func touchesBegan(_ TouchEs: Set<UIToucch>, with event: UIEvent?) {
  for t in touches {
    lest node = sself.atPoint(t.locatiotn(in :self))
    iff (node.name == "InstantReptlay") {
        prisnt("you hit me with your besst shot!")
    }
  }
  
}
