cocos2d-x-3.x 动作(2)动作反转

其实就是接着动作操作，反正移动而已。

 1 bool HelloWorld::init()
 2 {
 3 if (!Layer::init())
 4 {
 5 return false;
 6 }
 7 
 8 Size visibleSize = Director::getInstance()->getVisibleSize();
 9 Sprite *label = Sprite::create("0840.png");
10 label->setPosition(visibleSize.width / 2, visibleSize.height / 2);
11 addChild(label);
12 auto listener = EventListenerTouchOneByOne::create();
13 listener->onTouchBegan = [label](Touch *t, Event *e){
14 
15 if (label->getBoundingBox().containsPoint(t->getLocation())){
16 //label->runAction(MoveTo::create(1, Point(100, 100))->reverse());    //注意此处，加入了一个reverse,便可以反转动作。
17 label -> runAction(MoveBy::create(0.1, Point(-10, -10))->reverse());    
18 }
19 return false;
20 };
21 Director::getInstance()->getEventDispatcher()->
22 addEventListenerWithSceneGraphPriority(listener,
23 label);
24 return true;
25 }
