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。

 1 bool HelloWorld::init()
 2 {
 3     //////////////////////////////
 4     // 1. super init first
 5     if ( !Layer::init() )
 6     {
 7         return false;
 8     }

10     SpriteFrameCache *cache = SpriteFrameCache::getInstance();
11     cache->addSpriteFramesWithFile("a6.plist");
12
13     Vector<SpriteFrame*> vec;
14     char name[15];
15     memset(name, 0, 15);
16
17     for (int i = 1; i <=7; i++){
18         sprintf(name, "a6_%02d.png", i);
19         vec.pushBack(cache->getSpriteFrameByName(name));
20     }
21
22     Animation *animation = Animation::createWithSpriteFrames(vec, 0.1f, 1);
23
24     Animate *animate = Animate::create(animation);
25
26     auto sprite = Sprite::create();
27     addChild(sprite);
28     sprite->setPosition(Vec2(200, 200));
29     //sprite->runAction(RepeatForever::create(animate));
30
31     auto label = LabelTTF::create("Touch", "Courier", 30);
32     label->setPosition(Vec2(500, 500));
33     addChild(label);
34
35     int i = 10;
36
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;
46     }
47     return false;
48     };
49     //notifation:here is "this" not "label" because if here is "label", Touch *t equals to "label"
50     Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener,this);
51     return true;
52 }

init
