如何改變場景的MouseDown

Question

我特林創建一個遊戲菜單，我得到了這樣的事情

class StartGame: SKScene { 
    override func didMoveToView(view: SKView) { 
     backgroundColor = SKColor.blackColor() 
     let startButton = SKSpriteNode(imageNamed: "startGame") 
     startButton.position = CGPointMake(size.width/2, size.height/2) 
     startButton.name = "startButton" 
     addChild(startButton) 
    } 

    override func mouseDown(theEvent: NSEvent) { 
     if( ... ) 
    } 
} 

有ofcourse會更喜歡「保存遊戲」，「退出」和類似按鈕那。還有我的問題。我想通過點擊一個名爲「startGame」

按鈕從StartGame改變現場GameScene在實現mouseDown StartGame這樣的：

override func mouseDown(theEvent: NSEvent) { 
    let location = theEvent.locationInNode(self) 
    let node = self.nodeAtPoint(location) 

    if (node.name == "startButton") { 
     let nextScene = GameMenu(size: self.size) 
     scene?.view?.presentScene(nextScene, transition: SKTransition.crossFadeWithDuration(1)) 
    } 
}
