Question

在新的cocos2d-x 3.0rc中，我想检测图层中的触摸。我的课程中有过多的功能，如下所述。

virtual bool onTouchBegan(CCTouch* touch, CCEvent* event);
virtual void onTouchMoved(CCTouch* touch, CCEvent* event);
virtual void onTouchEnded(CCTouch* touch, CCEvent* event);

但未检测到触摸。任何想法都会发生这种情况吗？

Answer 1

要启用触摸，我使用了以下代码。在cocos2d-x 3.0 RC1中完美运行

void class_name::onEnter()
{
    Layer::onEnter();

    // Register Touch Event
    auto dispatcher = Director::getInstance()->getEventDispatcher();
    auto listener = EventListenerTouchOneByOne::create();

    listener->onTouchBegan = CC_CALLBACK_2(class_name::onTouchBegan, this);
    listener->onTouchMoved = CC_CALLBACK_2(class_name::onTouchMoved, this);
    listener->onTouchEnded = CC_CALLBACK_2(class_name::onTouchEnded, this);

    dispatcher->addEventListenerWithSceneGraphPriority(listener, this);
}

在Cocos2d-x 3.0中检测触摸

在（HelloWorld.h）中编写代码 {

cocos2d::EventListenerTouchAllAtOnce *Listner;
void onTouchesBegan(const std::vector<cocos2d::Touch *> &touches, cocos2d::Event *event);
    void onTouchesMoved(const std::vector<cocos2d::Touch *> &touches, cocos2d::Event *event);
    void onTouchesEnded(const std::vector<cocos2d::Touch *> &touches, cocos2d::Event *event);

}

在init方法中编写代码（HelloWorld.cpp） {

 Listner = EventListenerTouchAllAtOnce::create();
    Listner->onTouchesBegan = CC_CALLBACK_2(HelloWorld::onTouchesBegan, this);
    Listner->onTouchesMoved = CC_CALLBACK_2(HelloWorld::onTouchesMoved, this);
    Listner->onTouchesEnded = CC_CALLBACK_2(HelloWorld::onTouchesEnded, this);
    _eventDispatcher->addEventListenerWithSceneGraphPriority(Listner, this);

}

Answer 3

enable touch on init() Or onEnter()

this->setTouchEnabled(true);
CCDirector::sharedDirector() -> getTouchDispatcher() -> addTargetedDelegate( this, 0, true );

Cocos2d-x 3.0rc没有检测到触摸
