在swift spriteKit中使用NSUserDefault在新场景中显示高分

我正在用SpriteKit做一个游戏，它保存了玩家的高分。当游戏结束时，它会过渡到另一个场景（结束场景）。我搞不懂如何在最后一幕中显示高分。我的高分代码：

func updateHighScore(){
    //save current points label value
    let pointsLabel = childNodeWithName("pointsLabel") as! DDPointsLabel
    let highScoreLabel = childNodeWithName("highScoreLabel") as! DDPointsLabel

    if highScoreLabel.number < pointsLabel.number {
        highScoreLabel.setTo(pointsLabel.number)

        let defaults = NSUserDefaults.standardUserDefaults()
        defaults.setInteger(highScoreLabel.number, forKey: "highscore")
    }
}

func loadHighScore(){
    let defaults = NSUserDefaults.standardUserDefaults()
    let highScoreLabel = childNodeWithName("highScoreLabel") as! DDPointsLabel
    highScoreLabel.setTo(defaults.integerForKey("highscore"))

}

func updatehighhscore（）{
//保存当前点标签值
将pointsLabel=childNodeWithName（“pointsLabel”）设为！DDPointsLabel
将highScoreLabel=childNodeWithName（“highScoreLabel”）设为！DDPointsLabel
如果highScoreLabel.number

要加载highscore，您需要一个int来保存highscore，我不确定您想用highscore标签做什么，但要加载它，您需要执行

var highscore=defaults.integerworky（“highscore”）

对于标签，您可以执行

highScoreLabel.text=“Score\（highscore）”

此答案假设您在游戏场景中正确显示了分数。如果是这样，那么除了游戏场景文件之外，还要创建两个其他Swift文件：1）GameState.Swift和2）EndGameScene.Swift

在GameState.swift中，创建一个如下的共享实例

class GameState {
  var score: Int
  var highScore: Int


  class var sharedInstance: GameState {
    struct Singleton {
      static let instance = GameState()
    }

    return Singleton.instance
  }


    init() {
      score = 0
      highScore = 0

      // Load game state
      let defaults = NSUserDefaults.standardUserDefaults()

      highScore = defaults.integerForKey("highScore")
      stars = defaults.integerForKey("stars")
    }

    func saveState() {

      // Update highScore if the current score is greater
      highScore = max(score, highScore)

      // Store in user defaults
      let defaults = NSUserDefaults.standardUserDefaults()
      defaults.setInteger(highScore, forKey: "highScore")
      defaults.setInteger(stars, forKey: "stars")
      NSUserDefaults.standardUserDefaults().synchronize()
    }
}

    // Score
    let lblScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
    lblScore.fontSize = 60
    lblScore.fontColor = SKColor.whiteColor()
    lblScore.position = CGPoint(x: self.size.width / 2, y: 300)
    lblScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.Center
    lblScore.text = String(format: "%d", GameState.sharedInstance.score)
    addChild(lblScore)

    // High Score
    let lblHighScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
    lblHighScore.fontSize = 30
    lblHighScore.fontColor = SKColor.cyanColor()
    lblHighScore.position = CGPoint(x: self.size.width / 2, y: 150)
    lblHighScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.Center
    lblHighScore.text = String(format: "High Score: %d", GameState.sharedInstance.highScore)
    addChild(lblHighScore)

在游戏场景文件中，确保正确创建了标签。如果是这样，那么找到你的代码，为你的玩家创建点数。也许在发生碰撞的地方。然后添加游戏状态共享实例。它看起来像这样

lblStars.text = String(format: "X %d", GameState.sharedInstance.stars)
lblScore.text = String(format: "%d", GameState.sharedInstance.score)

在EndGameSene中，确保使用标签调用GameState.sharedInstance。代码看起来像这样

class GameState {
  var score: Int
  var highScore: Int


  class var sharedInstance: GameState {
    struct Singleton {
      static let instance = GameState()
    }

    return Singleton.instance
  }


    init() {
      score = 0
      highScore = 0

      // Load game state
      let defaults = NSUserDefaults.standardUserDefaults()

      highScore = defaults.integerForKey("highScore")
      stars = defaults.integerForKey("stars")
    }

    func saveState() {

      // Update highScore if the current score is greater
      highScore = max(score, highScore)

      // Store in user defaults
      let defaults = NSUserDefaults.standardUserDefaults()
      defaults.setInteger(highScore, forKey: "highScore")
      defaults.setInteger(stars, forKey: "stars")
      NSUserDefaults.standardUserDefaults().synchronize()
    }
}

    // Score
    let lblScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
    lblScore.fontSize = 60
    lblScore.fontColor = SKColor.whiteColor()
    lblScore.position = CGPoint(x: self.size.width / 2, y: 300)
    lblScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.Center
    lblScore.text = String(format: "%d", GameState.sharedInstance.score)
    addChild(lblScore)

    // High Score
    let lblHighScore = SKLabelNode(fontNamed: "ChalkboardSE-Bold")
    lblHighScore.fontSize = 30
    lblHighScore.fontColor = SKColor.cyanColor()
    lblHighScore.position = CGPoint(x: self.size.width / 2, y: 150)
    lblHighScore.horizontalAlignmentMode = SKLabelHorizontalAlignmentMode.Center
    lblHighScore.text = String(format: "High Score: %d", GameState.sharedInstance.highScore)
    addChild(lblHighScore)

然后，回到游戏场景，添加gameOver属性

var gameOver = false

仍在游戏场景中，添加以下方法：

func endGame() {

  gameOver = true

  // Save high score
  GameState.sharedInstance.saveState()

  let reveal = SKTransition.fadeWithDuration(0.5)
  let endGameScene = EndGameScene(size: self.size)
  self.view!.presentScene(endGameScene, transition: reveal)
}

一定要打电话给

endGame() 

。。。无论玩家在哪里耗尽生命

您可能需要添加：

if gameOver {
  return 
}

。。。在游戏场景中，更新游戏性的位置
