cocos2d-x之多点触摸事件

//全部所有的触摸点一起触发
    auto listener = EventListenerTouchAllAtOnce::create();
    
    listener->onTouchesBegan = [](std::vector<Touch*> ts, Event *e){
        log("onTouchesBegan");
    };
    
    //获得触摸点的数量
    listener->onTouchesMoved = [](std::vector<Touch*> ts,Event *e){
        log("touches moved,and touch count is %ld", ts.size());
    };
    
    //this代表，使用的是当前的层作为节点
    Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, this);
