Event listening

 

    auto listen = EventListenerTouchOneByOne::create();    listen->setSwallowTouches(true);    listen->onTouchBegan = [](Touch* touch,Event* event){        CCLog("onTouchBegan");        return true;    };    listen->onTouchMoved = [](Touch* touch,Event* event){        CCLog("onTouchMoved");    };    listen->onTouchEnded = [](Touch* touch,Event* event){        CCLog("onTouchEnded");    };        Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listen, this);

 

The same event listener can bind multiple objects, but must use a copy of the event listener, for example:

Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listen, sprite);Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listen->clone(), ttf);

 

Director: getinstance ()-> geteventdispatcher () can also be replaced by _ eventdispatcher.
