迅捷的声音效果//为什么我的代码不起作用？

Question

我一直在尝试制作一款快速教自己的游戏，似乎无法让这些代码发挥作用。我对此非常陌生，似乎无法找出它为什么不起作用... XCode没有标记任何问题，构建成功，调试器甚至打印“进入第1阶段并进入第2阶段......有什么帮助？

我导入了AVFoundation ..

class GAME {

    class func SuperStartGame(playerwhowon1: SKSpriteNode) {

            var player = AVAudioPlayer()

        func PlaySound() {
            guard let URL = Bundle.main.url(forResource: "PowerUp", withExtension: "mp3")
                else {
                    print("Didn't Find URL")
                    return
            }

            do {
                print("Got to Stage 1")

                try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
                try AVAudioSession.sharedInstance().setActive(true)

                player = try AVAudioPlayer(contentsOf: URL, fileTypeHint: "mp3")
                player.prepareToPlay()
                player.play()

                print("Got to Stage 2")
            } catch let error as NSError {
                print("error: \(error.localizedDescription)")
            }

        RoundNumber += 1
        Round.text = "Round \(RoundNumber)"

        if playerwhowon1 == Mine {
            MyScore.run(addscoreM) {
                PlaySound()
                    Round.run(NewRoundForRound) {

...

代码继续......这是与声音相关的唯一部分。我将声音文件添加到Xcode中，并确保将其添加到项目目标中...它在我的主要包中。

1. 确保您的设备没有静音

2. 将mp3文件复制到bundle

3. 示例VC播放声音：

   class ViewController: UIViewController {   
       var game = Game()
   
       @IBAction func playAction(_ sender: UIButton) {
           game.playSound()
       }
   
   }
   
   class Game {
   
       var player: AVAudioPlayer?
   
       func playSound() {
           guard let URL = Bundle.main.url(forResource: "SampleAudio", withExtension: "mp3") else {
               print("Didn't Find URL")
               return
           }
   
           do {
               try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
               try AVAudioSession.sharedInstance().setActive(true)
   
               player = try AVAudioPlayer(contentsOf: URL, fileTypeHint: "mp3")
               player?.prepareToPlay()
               player?.play()
   
           } catch let error as NSError {
               print("\(error.localizedDescription)")
           }
   
       }
   
   }
