音量滑塊對cocos2d的V3？

Question

我想要做的音頻滑塊控制在cocos2d V3音量。 正如我可以在cocos2d V2滑塊可以看到通過該https://github.com/YannickL/CCControlExtension 被創建，但在V3實在不行。我該怎麼做？謝謝！

這是我如何使用V3.2.1 CCSlider控制做一個音頻滑塊。它是椰樹的標準UI玩具的一部分，用這個來代替擴展：

CCSpriteFrame *frRuler = [CCSpriteFrame frameWithImageNamed:@"slider_track.png"]; 
CCSpriteFrame *frKnob = [CCSpriteFrame frameWithImageNamed:@"slider_knob.png"]; 
_mainGain = [[CCSlider alloc] initWithBackground:frRuler andHandleImage:frKnob]; 
[self addChild:_mainGain]; 
[_mainGain setTarget:self selector:@selector(onMainGainChange:)]; 
_mainGain.positionType = CCPositionTypePoints; 
_mainGain.anchorPoint = ccp(.5, .5); 
_mainGain.visible  = YES; 
_mainGain.position  = ccp(kScreenWidth/2, kScreenHeight/2 - deviceOffset(55)); 
_mainGain.continuous = YES; 
_mainGain.sliderValue = [BattlesStatus sharedBattlesStatus].settings.audio.masterVolumeGain; 

的「onMainGainChanged：」選擇被調用時在每個更新間隔的滑塊滑動。我對其進行處理如下：

- (void)onMainGainChange:(id)sender { 

    CCSlider *sl = (CCSlider *) sender; 
    TRACE(@"New setting is %f", sl.sliderValue); 
    [BattlesStatus sharedBattlesStatus].settings.audio.masterVolumeGain = sl.sliderValue; 
    _isSettingsDirty = YES; 
}
