Question

I’m attempting to write a tile engine and I have a method in one of my classes and I need a way of being able to use one loop to perform the method for all existing instances of the class, for instance if I have a GameObject called tile, and another called enemy would there be a way of calling GameObject::render for both of them without having to specify their names within the loop?

Answer 1

You have to do some work. For instance in the constructors for your GameObject class you could add a pointer to the GameObject being created to a list. Then in your destructor you could remove the pointer to the object being destroyed from the same list. That way you have a list of pointers to all the live GameObject’s which you can loop through whenever you feel the need.
