如何在快速SKSpriteNode中添加按钮效果

Question

我有个Var Button

var soundButton: SKSpriteNode! = nil

细节就像。

soundButton           =   SKSpriteNode(imageNamed: "\(soundImg)")
soundButton.position  =   CGPoint(x: frame.size.width*0.08 , y:frame.size.width*0.08);
soundButton.size      =   CGSizeMake(frame.size.width*0.10,frame.size.width*0.10 )
self.addChild(soundButton)

比我如何添加按钮效果，如按钮颜色灯，当我点击它，并作出声音也。

这样做的一种方法是，您可以在选择按钮时更改图像。

像这样进入您的touchesBegan方法：

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
    /* Called when a touch begins */

    for touch in (touches as! Set<UITouch>) {
        let location = touch.locationInNode(self)

        if self.nodeAtPoint(location) == self. soundButton {
            soundButton.texture = SKTexture(imageNamed: "soundSelected")

        }
    }
}

如果您想要使用延迟转到另一个场景，并且需要转换，可以在if语句中使用以下代码：

let reveal = SKTransition.flipHorizontalWithDuration(0.5)
let letsPlay = playScene(size: self.size)
self.view?.presentScene(letsPlay, transition: reveal)
