With our factory now in place, we can start altering our GameObject classes to use it. Our first step is to ensure that we have a
Creator class for each of our objects. Here is one for Player:
class PlayerCreator : public BaseCreator
{
GameObject* createGameObject() const
{
return new Player();
}
};This can be added to the bottom of the Player.h file. Any object we want the factory to create must have its own Creator implementation. Another addition we must make is to move LoaderParams from the constructor to their own function called load. This stops the need for us to pass the LoaderParams object to the factory itself. We will put the load function into the GameObject base class, as we want every object to have one.
class GameObject
{
public:
virtual void draw()=0;
virtual void update()=0;
virtual void clean()=0;
// new load function
virtual void load(const LoaderParams* pParams)=0;
protected:
GameObject() {}
virtual...
