记录一下触摸事件的创建与使用

    auto listener = EventListenerTouchOneByOne::create();//创建一个监听器
    listener->setSwallowTouches(true);//不向下传递触摸

    //触摸开始
    listener->onTouchBegan = [=](Touch* touch, Event* event) {
        log("onTouchBegan");
        //获取触摸目标
        auto target = dynamic_cast<Sprite*>(event->getCurrentTarget());
        //获取触摸点
        Point locationInNode = target->convertToNodeSpace(touch->getLocation());
        //获取目标的轮廓大小
        Size s = target->getContentSize();
        //区域位置(x,y,width,height)
        Rect rect = Rect(0, 0, s.width, s.height);
        //判断触摸点是否在目标轮廓区域内
        if (rect.containsPoint(locationInNode)) {
            auto moveToAction = MoveTo::create(1, Vec2(150, 200));
            _skill_1->runAction(moveToAction);
            return true;//在，返回true
        }
        else {
            return false;//不在，返回false
        }
    };

    //触摸移动
    listener->onTouchMoved = [](Touch* touch, Event* event) {
        log("onTouchMoved");
    };

    //触摸结束
    listener->onTouchEnded = [=](Touch* touch, Event* event) {
        log("onTouchEnded");
        auto moveToAction = MoveTo::create(1, Vec2(150, 120));
        _skill_1->runAction(moveToAction);
    };

    //触摸取消
    listener->onTouchCancelled = [](Touch* touch, Event* event) {
        log("onTouchEnded");
    };

    //最后将精灵添加到事件监听器中
    _eventDispatcher->addEventListenerWithSceneGraphPriority(listener, _skill_1);
