如何限制Swift 3中球的击球次数？

Question

我正在创建一个游戏，在第一级我希望玩家在某个时间点击圈子。例如：玩家可以获得多少次点击至少15秒。 ＆安培;当玩家在该特定时间限制内达到最大敲击限制时。然后，祝贺玩家。请给我一些帮助，如何建立这个。 这里有一些试图限制圆圈触摸的代码。

 let maxScore = 10
 var currentScore = 0

func playerScored(amount: Int) {

currentScore += amount

// I will be playing some sort of sound
// ...
}

override func update(_ currentTime: TimeInterval) {

if currentScore >= maxScore { // Player made it
    self.view!.presentScene(SKScene(fileNamed: "WinnerScene"))
}

Answer 1

我希望您知道UITapGestureRecognizer查看Apple有关点按UITapGestureRecognizer的文档，您会得到一些想法

Answer 2

• 目标 - c 代码如下：

UITapGestureRecognizer * singleTap = [[[UITapGestureRecognizer alloc] initWithTarget：self action：@selector（doSingleTap）] autorelease]; singleTap.numberOfTapsRequired = 1; [self.view addGestureRecognizer：singleTap];

UITapGestureRecognizer * doubleTap = [[[UITapGestureRecognizer alloc] initWithTarget：self action：@selector（doDoubleTap）] autorelease]; doubleTap.numberOfTapsRequired = 2; [self.view addGestureRecognizer：doubleTap];

[singleTap requireGestureRecognizerToFail：doubleTap];

- ＆gt;您可以将其转换为 swift 。
