Cocos2d-X动作展示《一》，cocos2d-x《一》
由于Cocos2d-X中的动作较多，我将所有的动作制作成了一个滚动视图，每个滚动视图上都有动作名，单击滚动视图就可以展示相应的动作
程序效果图：
使用滚动视图实现动作切换
动作展示
程序代码：
首先创建一个ActionShow类
在ActionShow.h中的代码
#ifndef _ActionShow_H_
#define _ActionShow_H_

USING_NS_CC_EXT;

bool init();
CREATE_FUNC(ActionShow);
bool ccTouchBegan(CCTouch*, CCEvent*);
void ccTouchEnded(CCTouch*, CCEvent*);
CCNode* _c;
void testAction(int idx, CCLayerColor*);
void func();
void funcN(CCNode*);
void funcND(CCNode*, void*);
};
#endif
ActionShow.cpp中的代码
