重复时，Skaction.playsoundfilenamed崩溃 – 精灵工具包

我有sprite kit SKAction.playSoundFileNamed的问题。 在实践中，经过一段时间它正确播放，应用程序崩溃说它不会加载。 该文件包含在捆绑导入中，项目文件存在且一切都已正确设置。

唯一的问题，经过一段时间我玩，我会崩溃说它找不到文件，或者至少无法加载。

我的问题是，每次声音SKAction.playSoundFileNamed有没有办法充电？

编辑 – 已解决

//init var sound = SKAction.playSoundFileNamed("sound.mp3", waitForCompletion: false) var sound2 = SKAction.playSoundFileNamed("sound2.mp3", waitForCompletion: false) //in the code call function when play sound: playSound(sound) ... func playSound(soundVariable : SKAction) { runAction(soundVariable) } 

实例化的预加载声音不再生成崩溃

Answer 1

前声音变量

 //init var sound = SKAction.playSoundFileNamed("sound.mp3", waitForCompletion: false) var sound2 = SKAction.playSoundFileNamed("sound2.mp3", waitForCompletion: false) //in the code call function when play sound: playSound(sound) ... func playSound(soundVariable : SKAction) { runAction(soundVariable) } 

Answer 2

我有一个类型为SKNode的小助手类用于播放音频文件。 注意：必须将助手对象添加到SKScene层次结构才能播放音频。

 import UIKit enum SFX_TYPE:Int { case NEW_LEVEL = 0 case BANG = 1 } let SFXContainer:[SFX_TYPE:[SKAction]] = [ SFX_TYPE.NEW_LEVEL : [SKAction.playSoundFileNamed("newlevel.m4a", waitForCompletion: true)], SFX_TYPE.BANG : [ SKAction.playSoundFileNamed("explosion1.m4a", waitForCompletion: true), SKAction.playSoundFileNamed("explosion2.m4a", waitForCompletion: true), SKAction.playSoundFileNamed("explosion3.m4a", waitForCompletion: true), SKAction.playSoundFileNamed("explosion4.m4a", waitForCompletion: true) ] ] class SabilandSound: SKNode { required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) } deinit { Helper.masterObserverRemove(self) } override init() { super.init() NSNotificationCenter.defaultCenter().addObserver(self, selector: Selector("masterPlaySFX:"), name: NCNPlaySFX, object: nil) } func masterPlaySFX(n:NSNotification) { let st = SFX_TYPE(rawValue: n.userInfo![NCNPlaySFX] as! Int)! let c = SFXContainer[st]! let a = SFXContainer[st]![Helper.randomBetween(0, max: c.count, includeMax: false)] runAction(a) } }
