我制作的游戏包括一旦玩家死亡后出现的高分标签，以及重启按钮。总的来说，高分，这是一个整数，工作正常，但有一个问题。如果你在那一轮中达到了新的高分，那么你刚刚完成就必须再次死去才能显示新的高分。让我说我玩游戏时高分已经是15而且当高分标签出现时我得到17它仍然显示15.我重新开始游戏并且高分再次出现它现在将显示17.高分我想要的时候没有更新。

好的，如果生命数= 3，我就加入了这个：
if lifenumber == 3{
if (scorenumber > Highscore){
var Highscoredefault = NSUserDefaults.standardUserDefaults()
Highscoredefault.setValue(scorenumber, forKey: "HighScore")
}
var Highscoredefault = NSUserDefaults.standardUserDefaults()
if (Highscoredefault.valueForKey("HighScore") != nil){
Highscore = Highscoredefault.valueForKey("HighScore") as! NSInteger
}
else{
Highscore = 0
}
self.addChild(Highscorelabel)
createButton()
person.zPosition = -6
person.texture = SKTexture (imageNamed: "Person1")
Died = true
}
答案 0 :(得分：1)
初始化时，您似乎只设置了text的{{1}}属性。如果您希望Highscorelabel在死亡后立即更新，那么您应该在此时更新它。
Highscorelabel答案 1 :(得分：0)
我认为你必须加上这个：
在func didBeginContact(contact: SKPhysicsContact) 中的//ADD THIS
if scorenumber > Highscore {
Highscore = scorenumber
Highscorelabel.text = "HighScore: \(Highscore)"
}
之后
package msg_RepAndOpt;
message RepAndOpt
{
repeated string name = 1;
optional string surname = 2;
...
// there are lots of others.
}
