问题描述
是否可以通过SKAction .
Is there a way to regulate the volume of sound played via SKAction playSoundFileNamed:waitForCompletion:.
我想实现一个简单的音乐&我的游戏中的音效滑块.由于可以通过AVAudioPlayer播放背景音乐，因此可以轻松控制背景音乐，但是所有声音效果都是通过SKAction播放的.
I would like to implement a simple music & sound effects slider in my game. I can easily control background music since i play it via AVAudioPlayer, but all sound effects are played via SKAction.
推荐答案
不幸的是，您无法使用SKAction修改音量，因此您也必须使用AVAudioPlayer来实现效果.您可以按照您的想法使用runBlock实现自定义playSoundFileNamed:waitForCompletion:volume :，因此您的代码与使用playSoundFileNamed:waitForCompletion:不会有太大不同.
Unfortunately you can't modify the volume using SKAction, so you have to use AVAudioPlayer for your effects too.You could implement a custom playSoundFileNamed:waitForCompletion:volume: using runBlock as you already thought, so your code won't be very different then using playSoundFileNamed:waitForCompletion:.
