Cocos2d-x之动作(偏移)

Cocos2d-x之动作(偏移)

       bool HelloWorld::init(),添加内容如下:

//获取可见区域的大小

    Size visibleSize = Director::getInstance()->getVisibleSize();

    //定义一个label,这里使用了c++11中的auto自动匹配

    auto label = LabelTTF::create("bobo", "Courier", 30);

    //设置label在屏幕的中间

    label->setPosition(Point(visibleSize.width / 2, visibleSize.height / 2));

    addChild(label);//将label添加进去

   

    //创建事件监听器

    auto listener = EventListenerTouchOneByOne::create();

    //设置listener

    listener->onTouchBegan = [label](Touch *t, Event *e){

        //判断点击的是否是label

        if (label->getBoundingBox().containsPoint(t->getLocation())) {

            //每个动作都有后缀为to或者by

            //to是指移动到特定的位置

            //by是根据当前状态继续执行,偏移等动作

            //设置动作,moveto(运行时间,运行到的位置)

//            label->runAction(MoveTo::create(1, Point(100,100)));

//            label->runAction(MoveBy::create(1, Point(30,30)));

            label->runAction(MoveBy::create(1, Point(-10, -10)));

        }

       

        return false;

    };

    //添加事件监听器

    Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, label);
