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
首先创建一个ActionMore类
ActionMore.h中的代码
#ifndef _ActionMore_H_
#define _ActionMore_H_
#include "cocos2d.h"
#include "cocos-ext.h"
USING_NS_CC;
USING_NS_CC_EXT;
class ActionMore : public CCLayer
{
public:
static CCScene* scene();
bool init();
CREATE_FUNC(ActionMore);
bool ccTouchBegan(CCTouch*, CCEvent*);
void ccTouchEnded(CCTouch*, CCEvent*);
CCNode* _c;
void testAction(int idx, CCLayerColor*);
};
#endif
ActionMore.cpp中的代码
#include "ActionMore.h"
