C++ cocos2dx中CCStandredTouchDelegate的类歧义错误（从驱动类的歧义转换）？

我正在子类化一个CCSprite，以便为sprite对象做旋转手势

为此，我需要使用CCTargetedTouchDelegate和CCStandardTouchDelegate 但即使在声明了这些委托的函数之后，我也会得到一个模糊错误

我的.h文件中的代码。

{

class DragSprite: public cocos2d::CCSprite, public cocos2d::CCTargetedTouchDelegate, public cocos2d::CCStandardTouchDelegate
{
    public:
        cocos2d::CCSize canvasSize;
        bool init();
        static DragSprite* createWithFile(const char *pszFileName);
        bool isTouchingOnSprite(cocos2d::CCPoint  touch);

        virtual bool ccTouchBegan(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);
        virtual void ccTouchMoved(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent);

CCTargetedTouchDelegate

和

CCStandardTouchDelegate

继承

CCTouchDelegate

，这种歧义来自于您有两个该类型的子对象。你为什么两者都用？我似乎没什么道理。@molbdnilo:如果我只使用CCStandardTouchDelegate，它会是一样的吗。i、 e任何精灵上的触摸事件将仅由相关精灵处理？我猜CCTargetedTouchDelegate只能处理特定精灵的事件，即使在一个层中有许多精灵
