Question

我试图让节点执行动作，然后在触摸按钮后进行场景转换。

这是我到目前为止所拥有的：

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
    var touch = touches as!  Set<UITouch>
    var location = touch.first!.locationInNode(self)
    var node = self.nodeAtPoint(location)
    var action = SKAction.moveToY(PlayButton.position.y + self.size.height, duration: 5)

    // If next button is touched, start transition to second scene
    if (node.name == "Balloon") {
        PlayButton.runAction(action)
        var secondScene = Scene2(size: self.size)
        var transition = SKTransition.flipVerticalWithDuration(1.0)
        secondScene.scaleMode = SKSceneScaleMode.AspectFill
        self.scene!.view?.presentScene(secondScene, transition: transition)}


}

一旦我使用模拟器点击按钮，场景就会转换而不执行操作。

您需要将序列操作与块操作一起使用。创建一个块动作来处理场景转换，如下所示：

if (node.name == "Balloon") {
        let sceneAction = SKAction.runBlock({
            let secondScene = Scene2(size: self.size)
            let transition = SKTransition.flipVerticalWithDuration(1.0)
            secondScene.scaleMode = SKSceneScaleMode.AspectFill
            self.scene!.view?.presentScene(secondScene, transition: transition)}
        })
        playButton.runAction(SKAction.sequence([action, sceneAction]))
}

场景过渡后的Skaction
