我想用swift在我的游戏中添加一个按钮

Question

所以在我的代码中我想添加一个SKSpriteNode，我可以将其用作转换到另一个场景的按钮，所以你可以告诉我如何在不使用gameScene.sks的情况下这样做

Answer 1

通常，您需要先创建一个子节点

override init(size: CGSize){

    let playButton = SKLabelNode()
    playButton.fontSize = 40
    playButton.text = NA_MENU_BTN_PLAY
    playButton.position = CGPoint(x: self.frame.midX, y: 300)
    //give it an unique name
    playButton.name = "Play"
    playButton.zPosition = 3
    addChild(playButton)

}

然后使用func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?)来处理触摸事件

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    for touch in (touches ){
        let location = touch.location(in: self)
        let touchNode = atPoint(location)

        if !((touchNode.name) != nil) { return }

        switch touchNode.name! {
            case "Play" :
                //your logic here!!
                let trialScene = TrialScene(size: self.size)
                self.view! .presentScene(trialScene, transition: transition)
        ｝
    ｝

}
