在场景 cocos2d 之间传递音频

Passing audio between scenes cocos2d(在场景 cocos2d 之间传递音频)

问题描述

刚开始使用 cocos2d，到目前为止我设置了不同的场景，例如主菜单、设置和关于.我在主菜单场景中添加了一些背景音乐，如下所示:

Just started working with cocos2d, so far ive set up different scenes eg main menu, settings and about. Ive added some background music to the main menu scene like so:

    [[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"TileMap.caf"];

音乐传递到其他场景，但当我返回主菜单场景时，声音会自行重新启动.

The music passes through to the other scenes, but when i go back to the main menu scene the sound restarts itself.

我现在才这样做大约 3 周，所以请放轻松 :)

I have only been doing this about 3 weeks now, so be easy on me :)

提前致谢.

推荐答案

你应该检查当前是否正在播放背景音乐 [[SimpleAudioEngine sharedEngine] isBackgroundMusicPlaying]，如果它当前正在播放则什么都不做而不是在主菜单场景中再次调用 playBackgroundMusic

you should check if background music is currently playing with [[SimpleAudioEngine sharedEngine] isBackgroundMusicPlaying], and if its currently playing just do nothing instead of calling playBackgroundMusic again in your main menu scene
