Question

我创建了一个得分和高分标签。每次玩家击中硬币时得分为1品脱，每当得分高于高分时高分得到更新。现在，除此之外，我想改变乐谱的功能。每次游戏重启时我都不希望它从0开始，我希望它从上一场比赛中玩家赢得的最后金额开始。因此，即使玩家关闭应用程序，也只是一个分数标签，随着时间的推移不断积累越来越多的分数。

这是我目前的代码，正常分数从每次玩家开始游戏时的0开始，每当分数达到高于高分的高分时获得更新的高分。

let highScoreLabel = SKLabelNode()

var score: Int {

    switch (self) {

    case coin: return 1

    default: return 0

    }
}

func playerScoreUpdate() {
    playerScorelabel.text = "Score: \(playerScore)"
}

func saveHighScore(high:Int) {
    NSUserDefaults.standardUserDefaults().setInteger(high, forKey: "highscore")
}
func highScore() -> Int {
    return NSUserDefaults.standardUserDefaults().integerForKey("highscore")
}
func resetHighScore() {
    NSUserDefaults.standardUserDefaults().removeObjectForKey("highscore")
}


func didBeginContact(contact: SKPhysicsContact) {
    var firstBody = SKPhysicsBody()
    var secondBody = SKPhysicsBody()

    if contact.bodyA.categoryBitMask < contact.bodyB.categoryBitMask {
        firstBody = contact.bodyA
        secondBody = contact.bodyB
    } else {
        firstBody = contact.bodyB
        secondBody = contact.bodyA
    }


    if (firstBody.categoryBitMask & UInt32(shipCategory)) != 0 && (secondBody.categoryBitMask & UInt32(obstacleCategory)) != 0 {
        ship.removeFromParent()
        let reveal = SKTransition.flipHorizontalWithDuration(0.5)
        let scene = GameOverScene(size: self.size)
        self.view?.presentScene(scene, transition: reveal)
    }

    if (firstBody.categoryBitMask & UInt32(shipCategory)) != 0 && (secondBody.categoryBitMask & UInt32(coinCategory)) != 0 {
        secondBody.node?.removeFromParent() // Changed line.
        playerScore = playerScore + 1
        playerScoreUpdate()
    }

    if (firstBody.categoryBitMask & UInt32(shipCategory)) != 0 && (secondBody.categoryBitMask & UInt32(diamondCategory)) != 0 {
        secondBody.node?.removeFromParent() // Changed line.
    }

    //CHANGE TO YOU WON SCENE
    //CHECK TO SEE IF COINS ARE 10, THEN YOU WON
    if playerScore == 30 {

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

    }

    if playerScore > highScore() {
        saveHighScore(playerScore)
        println("New Highscore = " + highScore().description)
        highScoreLabel.text = "HighScore: \(highScore().description)"

    } else {
        println("HighScore = " + highScore().description )  // "HighScore = 100"

    }
}

在didMoveToView方法中，您只需将highscoreLabel的值设置为highScore()方法的值：

playerScore = highScore()

然后你应该可以从最后一个highScore开始。你不应该改变别的东西，因为代码的其他部分应该很好地完成它们的部分。
