swift - 运行功能需要单击而不是双击 SpriteKit

Question

我正在制作一个蓬松的鸟克隆，当鸟死时，弹出带有重新启动按钮的 spriteNode，但第一次单击正在停止动画（如果有的话），第二次单击是重新启动（）功能

下面是我如何使用按钮制作 SpriteNode 菜单：

 let menu = SKSpriteNode(texture: self.groundTex)
            menu.name = "menu"
            menu.position = CGPoint(x: 0, y: 0)
            menu.zPosition = 20
            let restartButton = SKSpriteNode(texture: self.heroTexture)
            restartButton.position = CGPoint(x:CGRectGetMidX(self.frame), y:CGRectGetMidY(self.frame));
            restartButton.zPosition = 40
            restartButton.name = "restart"

            let moveMenu = SKAction.moveTo(CGPoint(x: self.frame.size.width / 2, y: self.frame.size.height / 2), duration: 1.0)

            self.menuNode.addChild(menu)
            menuNode.addChild(restartButton)
            self.addChild(menuNode)

            menu.runAction(SKAction.sequence([
                moveMenu,
                SKAction.waitForDuration(NSTimeInterval(1.0)),
                makeGameEnd
                ]), withKey: "gameover"

这是我检测触摸的方式：

 override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    let touch  = touches.first
    let location = touch?.locationInNode(self)
    let node: SKNode = nodeAtPoint(location!)



    if node.name == "restart" {
       restart()
    }

更新 我的重启（）：

func restart() {
let scene = GameScene(size: self.size)
scene.scaleMode = .AspectFill
self.view?.presentScene(scene)
}

您可以像这样检查双击

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {

    let touch  = touches.first
    let location = touch?.locationInNode(self)
    let node: SKNode = nodeAtPoint(location!)

if touch.tapCount % 2 == 0 {

    if node.name == "restart" {
       restart()
    }
}
}
