将游戏实现为快速游戏
问题描述：
我已经在Xcode中创建了一个游戏，但是我想在玩家输掉的时候切换到屏幕上的游戏，此时main.storyboard文件是空白的。我发现这个解决方案Using a view controller for a game over scene将游戏实现为快速游戏
但是，我不确定如何实现这个到我的代码。我附上了我的代码，如果有人可以帮助我，这将不胜感激。

答
您应该设置GameOverScene并在需要时显示此场景。该RayWenderlich网站已经很多教程将告诉你如何做到这一点，很可能过多解释这里
这里是到
This page链接展示了如何实现一个级别完整覆盖）
但基本上你只需要创建一个新的场景，添加任何UI元素它，你需要的，然后从视图控制器，你可以拨打PresentScene，像这样
view.presentScene(scene)
示例代码：
class GameScene: SKScene {
var notificationLabel = SKLabelNode(text: "Tap the screen to win")
override func didMove(to view: SKView) {
self.backgroundColor = SKColor.black
addChild(notificationLabel)
notificationLabel.fontSize = 32.0
notificationLabel.color = SKColor.white
notificationLabel.fontName = "Thonburi-Bold"
notificationLabel.position = CGPoint(x: size.width/2, y: size.height/2)
}
func displayGameOver() {
let gameOverScene = GameOverScene(size: size)
gameOverScene.scaleMode = scaleMode
let reveal = SKTransition.flipHorizontal(withDuration: 0.5)
view?.presentScene(gameOverScene, transition: reveal)
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
displayGameOver()
}
}
class GameOverScene: SKScene {
var notificationLabel = SKLabelNode(text: "You Won")
override init(size: CGSize) {
super.init(size: size)
self.backgroundColor = SKColor.darkGray
addChild(notificationLabel)
notificationLabel.fontSize = 32.0
notificationLabel.color = SKColor.white
notificationLabel.fontName = "Thonburi-Bold"
notificationLabel.position = CGPoint(x: size.width/2, y: size.height/2)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
let gameScene = GameScene(size: size)
gameScene.scaleMode = scaleMode
let reveal = SKTransition.flipHorizontal(withDuration: 0.5)
view?.presentScene(gameScene, transition: reveal)
}
}
在任一场景中点击屏幕都会显示其他场景。你也应该可以通过viewcontroller来管理它，并做几乎相同的事情，但是我还没有这样做，我自己对SpriteKit还是比较新的。
希望这有助于
所有上面的代码是在GameScene.swift，本教程显示了IBOutlets添加到GameViewController.swift如果我添加一切都在那里，我怎么能叫它当游戏结束运行。目前我只有一个标签，弹出并停止游戏运行。对不起，如果我不理解，我是新的发展 – uz7
我会做一个例子，并很快发布 – Scriptable
谢谢，我期待着看到它。 – uz7
