Cocos2D-x游戏开发之五：CCControlPotentiometer and CCControlSlider

今天继续Cocos2D-x的基础CCControlPotentiometer and CCControlSlider，到目前为至我想大家已经很了解学习的基本方法了，所以直接上代码吧：

bool HelloWorld::init()

{

bool bRet = false;

do

{

CC_BREAK_IF(! CCLayer::init());

CCControlPotentiometer* potentiometer = CCControlPotentiometer::create("potentiometerTrack.png","potentiometerProgress.png","potentiometerButton.png");

potentiometer->setPosition(ccp(100, 200));

potentiometer->addTargetWithActionForControlEvents(this,cccontrol_selector(HelloWorld::onValueChange),CCControlEventValueChanged);

this->addChild(potentiometer);

CCControlSlider * slider = CCControlSlider::create("background.png","progress.png","sliderThumb.png");

slider->setPosition(100,80);

slider->setMinimumValue(0);

slider->setMaximumValue(10000);

slider->setValue(4000);

this->addChild(slider);

bRet = true;

} while (0);

return bRet;

}

void HelloWorld::menuCloseCallback(CCObject* pSender)

{

// "close" menu item clicked

CCDirector::sharedDirector()->end();

}

void HelloWorld::onValueChange( CCObject* pSender, CCControlEvent event )

{

CCControlPotentiometer* potentiometer = (CCControlPotentiometer* )pSender;

CCString* valueStr = CCString::createWithFormat("%f", potentiometer->getValue());

CCLOG(valueStr->getCString());

}

效果如下：
