Ios 降低一种声音的音量，而另一种声音在上面播放

在我的MenuScene.swift中，我在游戏开始时有一系列随机播放的声音：

       let soundNames = [
        "Sound/01.mp3",
        "Sound/02.mp3",
        "Sound/03.mp3"
    ]
    let randomSoundName = soundNames[Int(arc4random_uniform(UInt32(soundNames.count)))]
    _ = self.run(SKAction.playSoundFileNamed(randomSoundName, waitForCompletion: false))

…在我的GameViewController.swift中，我有一个在游戏开始时播放的背景曲目：

        // Start the background music:
    if let musicPath = Bundle.main.path(forResource:
        "Sound/BackgroundMusic.wav", ofType: nil) {
        let url = URL(fileURLWithPath: musicPath)
        do {
            musicPlayer = try AVAudioPlayer(contentsOf: url)
            musicPlayer.numberOfLoops = -1
            musicPlayer.prepareToPlay()
            musicPlayer.play()
        }
        catch { /* Couldn't load music file */ }
    }

当随机声音在背景音轨顶部播放时，我如何降低背景音轨的音量？

您可以尝试

audioPlayer？.volume=0.7

自定义音量。我将如何/在何处实现这一点？

musicPlayer？.volume=0.7

您必须将其放在需要的地方，您可以通过编程方式将音量从0.0更改为1.0
