我用swift创建游戏,得分很好。唯一的问题是高分。我创建了一个名为checkScores()的函数来检查分数是否大于高分。但是高分仍然是0。
func checkScores() {
if scoreInt > highScoreInt {
NSUserDefaults.standardUserDefaults().setInteger(scoreInt, forKey: "high")
highScoreInt = NSUserDefaults.standardUserDefaults().integerForKey("high")
NSUserDefaults.standardUserDefaults().synchronize()
highScoreLbl.text = "HIGHSCORE : \(highScoreInt)"
}
我在didMoveToView中调用它。 我在游戏场景中创建了高分标签和整数,并在initHud()
中设置标签文本func initHud() {
scoreLbl = SKLabelNode(fontNamed: "Geneva")
scoreLbl.position = CGPointMake(self.frame.size.width / 2, self.frame.size.height / 2)
scoreLbl.text = "0"
scoreLbl.fontSize = 100
scoreLbl.alpha = 0.5
addChild(scoreLbl)
highScoreInt = NSUserDefaults.standardUserDefaults().integerForKey("high")
NSUserDefaults.standardUserDefaults().synchronize()
highScoreLbl = SKLabelNode(fontNamed: "Geneva")
highScoreLbl.fontSize = 30
highScoreLbl.position = CGPointMake(150, self.frame.size.height - 80)
highScoreLbl.text = "HIGHSCORE : \(highScoreInt)"
addChild(highScoreLbl)
}
当我运行游戏时,高分仍然为零。我试图将checkScore()放在didBeginContact中并且工作正常。但为什么?因为每帧都会更新物理? 是否有可能在didMoveToView中检查它?谢谢!
答案 0 :(得分:0)
将此代码放在update()
中 var highscore = 1
let userDefaults = NSUserDefaults.standardUserDefaults()
highscore = userDefaults.integerForKey("highscore")
userDefaults.setValue(highscore, forKey: "highscore")
if scoreCount > highscore {
userDefaults.setValue(scoreCount, forKey: "highscore")
}
highScoreLabel.text = "highscore: \(highscore)"
userDefaults.synchronize()
