停止在 SceneKit 中的节点上播放声音

Question

我有一个手势识别器的以下代码，它会在被点击时播放喇叭，并在释放时停止：

@objc func didPressHorn(_ sender: UILongPressGestureRecognizer) {

    let tapLocation = sender.location(in: sceneView)

    if sender.state == .began {

        if (wasNodeTapped(node: hornNode!, tapLocation: tapLocation)) {
            hornNode!.runAction(SCNAction.playAudio(hornSound, waitForCompletion: false), forKey: "Horn")
            hornPlaying = true
        }

    } else if sender.state == .ended {
        if hornPlaying {
            // tried all the possible solutions, but the sound won't stop
            hornNode?.removeAction(forKey: "Horn")
            hornNode?.removeAllActions()
            hornNode?.isPaused = true
            hornSound.volume = 0
            hornPlaying = false
            print("Horn off") //gets printed!
        }
    }
}

如您所见，我正在尝试所有可能的解决方案（我知道），并且打印语句也被打印出来。但是，声音不会关闭。你有什么想法，为什么？

我不知道这是否是最好的想法/做法，但您可以尝试：self. hornNode.removeAllAudioPlayers()

希望对您有所帮助！
