Basically I have a load of empty...

so I changed some of the code


Entity *entities[2];
entities[0] = new Player;
entities[1] = new Map;

I added all the main classes to entity as virtual

I think I got the general idea but I am still getting errors


in main

Entity entities[2];
entities[0] = new Map;
entities[1] = new Player;

In my player class header file

Many entities.. several map blocks.. several items... 2 players most likely

By iterator I mean for loop :/ ... think I used the wrong term there.

Assuming I have an abstract class entity with a...

I am making a game entity class for a 2d allegro game of mine.

closing and reopening the file worked

using

before, not after
seekg(ios::beg) also worked
