c++ - cocos2d-x CCControlSlider 不滑动

Question

我尝试遵循 cocose2d-x 2.2 测试文件:cocos2d-x-2.2\samples\Cpp\TestCpp\Classes\SchedulerTest\SchedulerTest.h

我实现了 slider 控件，我看到了它和:

virtual bool ccTouchBegan(CCTouch* touch, CCEvent* event);
virtual void ccTouchMoved(CCTouch* touch, CCEvent* event);
virtual void ccTouchEnded(CCTouch* touch, CCEvent* event);

功能在我尝试滑动时恰到好处地触发但它根本不滑动这就是我所拥有的:默认关闭菜单正在工作查找:

bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !CCLayer::init() )
    {
        return false;
    }

    CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();
    CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin();

    /////////////////////////////
    // 2. add a menu item with "X" image, which is clicked to quit the program
    //    you may modify it.

    // add a "close" icon to exit the progress. it's an autorelease object
    CCMenuItemImage *pCloseItem = CCMenuItemImage::create(
                                        "CloseNormal.png",
                                        "CloseSelected.png",
                                        this,
                                        menu_selector(HelloWorld::menuCloseCallback));

    pCloseItem->setPosition(ccp(origin.x + visibleSize.width - pCloseItem->getContentSize().width/2 ,
                                origin.y + pCloseItem->getContentSize().height/2));

    // create menu, it's an autorelease object
    CCMenu* pMenu = CCMenu::create(pCloseItem, NULL);
    pMenu->setPosition(CCPointZero);
    this->addChild(pMenu, 1);

就你的问题7个月没回答，我会针对cocos2d-x的新版本来回答你的问题。此代码适用于 cocos2d-x 3.0:

cocos2d::extension::ControlSlider* slider = cocos2d::extension::ControlSlider::create(
    "images/buttons/container.png", "images/buttons/progress.png", "images/buttons/knob.png");
slider->setPosition(200, 200);
slider->setMinimumValue(0);
slider->setMaximumValue(10);
slider->setValue(3);
slider->addTargetWithActionForControlEvents(this, cccontrol_selector(IntroView::valueChangedCallback), cocos2d::extension::Control::EventType::VALUE_CHANGED);
addChild(slider);


void IntroView::valueChangedCallback(Ref* sender, cocos2d::extension::Control::EventType evnt)
{
    float value = static_cast<cocos2d::extension::ControlSlider*>(sender)->getValue();
    CCLOG(std::to_string(value).c_str());
}

不要忘记在您的项目中#include "GUI/CCControlExtension/CCControlExtensions.h" 并使用libExtensions。
