我试图用持续时间将 SKAudioNode 的音量淡化为 0,但持续时间似乎没有影响,音频立即停止:
let fireAudio = SoundManager.sharedInstance.fire //SKAudioNode
let stopAudio = SKAction.stop()
let fadeVolume = SKAction.changeVolumeTo(0.0, duration: 3.0)
let remove = SKAction.removeFromParent()
let sequence = SKAction.sequence([fadeVolume, stopAudio, remove])
fireAudio?.runAction(sequence)
有什么建议吗?谢谢
