cocos2d-x-3.x (6)动作侦听

其实主要是为了看一下动作是否结束

 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("what.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)));
17             //label -> runAction(MoveBy::create(0.1, Point(-20, -20))->reverse());
18             //label->runAction(Spawn::create(MoveBy::create(1, Point(100, 100)),    RotateBy::create(1, 360), NULL));    
19             //label->runAction(Sequence::create(MoveBy::create(1, Point(100,100)), RotateBy::create(1, 360), NULL));   
20             label->runAction(Sequence::create(
21                                       MoveBy::create(1,Point(100,100)),//第一个动作
22                                       RotateBy::create(1,360),//第二个动作
23                                       CallFunc::create([]{
24                 MessageBox("Action complete", "complete");//消息框
25             }), NULL));
26         }                                                              
27         return false;
28     };
29     Director::getInstance()->getEventDispatcher()->
30         addEventListenerWithSceneGraphPriority(listener,label);
31                                                                                    
32     //label->runAction(RotateBy::create(1, 180));
33     //label->runAction(Repeat::create(RotateBy::create(1,180),3));
34     //label->runAction(RepeatForever::create(RotateBy::create(1, 360)));
35     return true;
36 }

懒得删了其余的注释代码了。。。具体还是没玩的太流利。。。以后弄得比较明白了在回头看看
