c++ multiple inheritance function merging

Question

I have:

class XILightSource 
{
public:
    virtual XVec2 position() const = 0;
};

class XLightSprite : public XSprite, public XILightSource
{

};

The problem is that XSprite already has the same function position. How can i say to compiler, that i want to use XSprite::position function as an implementation of XILightSource::position() ?

Answer 1

override it and call XILightSource::position() :

class XLightSprite : public XSprite, public XILightSource
{
  public:
     XVec2 position() const { return  XSprite::position(); }
};
