在cocos2d中停止效果？

Question

经过这么多搜索,我找不到任何解决方案来停止cocos2d的效果.

我的效果是播放从数据库中获取的声音,所以为了阻止我必须这样的特定声音:

[[SimpleAudioEngine sharedEngine] stopEffect:[NSString stringWithFormat:@"%@.wav",sound]];

但是我收到了警告:stopEffect从指针生成整数而没有强制转换..

这是为什么 ？我怎么能停止一次播放的所有声音？或不是一个特定的？任何其他方式？

非常感谢 .

Answer 1

好的,你这样做:

ALuint soundEffectID;

//to start
soundEffectID=[[SimpleAudioEngine sharedEngine] playEffect:@"my sound"];
//to stop
[[SimpleAudioEngine sharedEngine] stopEffect:soundEffectID];

如果你没有soundEffectID,你可以做下一步.它帮助我解决了我的问题.

static NSMutableArray *soundsIdArr;

@implementation MusicAndSound

//It must be run before using sound
+(void)initSound
{
    NSLog(@"initSound");

    soundsIdArr = [NSMutableArray arrayWithCapacity:0];
    [soundsIdArr retain];
}

+(void)playSound:(NSString *)fileName
{
    [[SimpleAudioEngine sharedEngine] setEffectsVolume:1.0];

    soundEffectID = [[SimpleAudioEngine sharedEngine] playEffect:[[NSBundle mainBundle] pathForResource:fileName ofType:nil]];

    [soundsIdArr addObject:[NSString stringWithFormat:@"%i", soundEffectID]];
}

+(void)stopAllSounds
{
    [[SimpleAudioEngine sharedEngine] setEffectsVolume:0.0];

    for (int i=0; i<[soundsIdArr count]; i++)
    {
        [[SimpleAudioEngine sharedEngine] stopEffect:[[soundsIdArr objectAtIndex:i] intValue]];
    }

    [soundsIdArr removeAllObjects];
}

- (void)dealloc
{
    [soundsIdArr release];

    [super dealloc];
}
