ios - 我的音效循环的代码是什么

Question

我正在制作一个有趣的游戏，我想在每次结束时让我的音效循环播放，这些是我到目前为止的代码。

 override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    for touch in touches{
        let touchLocation = touch.location(in: self)
        if atPoint(touchLocation).name == "startGame"{
            let gameScene = SKScene(fileNamed: "GameScene")!
            gameScene.scaleMode = .aspectFill
            view?.presentScene(gameScene, transition: SKTransition.doorsOpenHorizontal(withDuration: TimeInterval(2)))
            self.run(SKAction.playSoundFileNamed("mainmenu.wav", waitForCompletion: false))

Answer 1

您无法使用 SKActions 在场景中播放背景音乐。改用 AVAudioPlayer:

if let filePath = Bundle.main.path(forResource: "mainmenu", ofType: "wav") {
    let url = URL(fileURLWithPath: filePath)
    do {
        let player = try AVAudioPlayer(contentsOf: url)
        player.numberOfLoops = -1
        player.play()
    } catch {
        // catch error if necessary
    }
}
