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

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。
