// So we need another way of defining objects, one which makes
// it easy for us to iterate through the attributes:
class Attribute
{
public:
virtual int GetValueRange()=0
virtual int GetValue()=0
virtual char* GetName()=0
};
class Health : public Attribute
{
...
};
class Energy : public Attribute
{
...
};
class Object
{
protected:
Attribute** Attributes;
public:
virtual int GetNumAttributes()=0;
...
};
class Villager : public Object
{
public:
int GetNumAttributes();
...
};
// Now it is easy to iterate through the attributes:
void Object::IterateThroughAttributes(void (*function)(Attribute*))
{
for(int i=0; i<GetNumAttributes(); i++)
{
function(Attributes[i]);
}
}
