五毛的cocos2d-x学习笔记08-动画

一个例子就够了，单击文本标签，执行动画。我也是小白，写这个demo的时候遇到了问题，单击文本标签游戏就死掉了。今天为了解决这个问题也是一晚没睡，到学习群里问大神，经过大神的指点解决了问题。原来是Animation和Animate的生命周期的关系。先记下。

 bool HelloWorld::init()
 {
     //////////////////////////////
     // 1. super init first
     if ( !Layer::init() )
     {
         return false;
     }

     SpriteFrameCache *cache = SpriteFrameCache::getInstance();
     cache->addSpriteFramesWithFile("a6.plist");

     Vector<SpriteFrame*> vec;
     char name[];
     memset(name, , );

     for (int i = ; i <=; i++){
         sprintf(name, "a6_%02d.png", i);
         vec.pushBack(cache->getSpriteFrameByName(name));
     }

     Animation *animation = Animation::createWithSpriteFrames(vec, 0.1f, );

     Animate *animate = Animate::create(animation);

     auto sprite = Sprite::create();
     addChild(sprite);
     sprite->setPosition(Vec2(, ));
     //sprite->runAction(RepeatForever::create(animate));

     auto label = LabelTTF::create("Touch", "Courier", );
     label->setPosition(Vec2(, ));
     addChild(label);

     int i = ;

     EventListenerTouchOneByOne *listener = EventListenerTouchOneByOne::create();
     listener->onTouchBegan = [=](Touch *t, Event *e){
     if (label->getBoundingBox().containsPoint(t->getLocation())){
         //notification: pay attention to the life cycle of Animation and Animate
         Animation *animation = Animation::createWithSpriteFrames(vec, 0.1f, );
         Animate *animate = Animate::create(animation);
         sprite->runAction(animate);
         log("i=%d", i);
         return true;
     }
     return false;
     };
     //notifation:here is "this" not "label" because if here is "label", Touch *t equals to "label"
     Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,this);
     return true;
 }

init

运行效果：
