Cocos2d-x_3.2 Demo ----------SpriteTest(2.2)

 1 class SpriteBatchNode1: public SpriteTestDemo
 2 {
 3 public:
 4     CREATE_FUNC(SpriteBatchNode1);
 5     SpriteBatchNode1();
 6     void addNewSpriteWithCoords(Vec2 p);// 根据新坐标创建精灵
 7     void onTouchesEnded(const std::vector<Touch*>& touches, Event* event);// 触摸结束回调
 8 
 9     virtual std::string title() const override;// 主标题
10     virtual std::string subtitle() const override;// 副标题
11 };

这个类和SpriteTest(2.1)的类差不多，只不过构造函数里实现由差异，来看一下实现：

 1 SpriteBatchNode1::SpriteBatchNode1()
 2 {
 3     auto listener = EventListenerTouchAllAtOnce::create();
 4     listener->onTouchesEnded = CC_CALLBACK_2(SpriteBatchNode1::onTouchesEnded, this);
 5     _eventDispatcher->addEventListenerWithSceneGraphPriority(listener, this);
 6 
 7     auto BatchNode = SpriteBatchNode::create("Images/grossini_dance_atlas.png", 50);// 创建精灵集合对象
 8     addChild(BatchNode, 0, kTagSpriteBatchNode);
 9     
10     auto s = Director::getInstance()->getWinSize();
11     addNewSpriteWithCoords( Vec2(s.width/2, s.height/2) );
12 }

上面函数里面添加精灵集合对象，其他可以参考SpriteTest(2.1)。

 1 void SpriteBatchNode1::addNewSpriteWithCoords(Vec2 p)
 2 {
 3     auto BatchNode = static_cast<SpriteBatchNode*>( getChildByTag(kTagSpriteBatchNode) );// 根据标志获取节点
 4     
 5     int idx = CCRANDOM_0_1() * 1400 / 100;
 6     int x = (idx%5) * 85;
 7     int y = (idx/5) * 121;
 8     
 9 
10     auto sprite = Sprite::createWithTexture(BatchNode->getTexture()/* 获得纹理 */, Rect(x,y,85,121));// 从精灵集合类中获取纹理
11     BatchNode->addChild(sprite);
12 
13     sprite->setPosition( Vec2( p.x, p.y) );
14 
15     ActionInterval* action;
16     float random = CCRANDOM_0_1();
17     
18     if( random < 0.20 )
19         action = ScaleBy::create(3, 2);
20     else if(random < 0.40)
21         action = RotateBy::create(3, 360);
22     else if( random < 0.60)
23         action = Blink::create(1, 3);
24     else if( random < 0.8 )
25         action = TintBy::create(2, 0, -255, -255);
26     else 
27         action = FadeOut::create(2);
28 
29     auto action_back = action->reverse();
30     auto seq = Sequence::create(action, action_back, nullptr);
31     
32     sprite->runAction( RepeatForever::create(seq));
33 }

除了注释的其他可以参考SpriteTest(2.1)。
