五毛的cocos2d-x學習筆記08-動畫，cocos2d-x08-
一個例子就夠了，單擊文本標簽，執行動畫。我也是小白，寫這個demo的時候遇到了問題，單擊文本標簽游戲就死掉了。今天為了解決這個問題也是一晚沒睡，到學習群裡問大神，經過大神的指點解決了問題。原來是Animation和Animate的生命周期的關系。先記下。

37 EventListenerTouchOneByOne *listener = EventListenerTouchOneByOne::create();
38 listener->onTouchBegan = [=](Touch *t, Event *e){
39 if (label->getBoundingBox().containsPoint(t->getLocation())){
40 //notification: pay attention to the life cycle of Animation and Animate
41 Animation *animation = Animation::createWithSpriteFrames(vec, 0.1f, 1);
42 Animate *animate = Animate::create(animation);
43 sprite->runAction(animate);
44 log("i=%d", i);
45 return true;

47 return false;

49 //notifation:here is "this" not "label" because if here is "label", Touch *t equals to "label"
50 Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,this);

運行效果：
