[CODE] Deleting a room

From: Andrew (object@alphalink.com.au)

I have written up a bit of code that is supposed to delete a room. It works
ok sometimes,
but other times it doesn't work at all. Sometimes it just does nothing, and
sometimes it
crashes the game. Here's the code - I know, it's awful...

BTW, num_of_rooms is an external integer which is the number of rooms at
startup...

void DeleteRoom( int room, struct char_data *ch)
{
        int i, y;

        temp = NULL;

        if (is_room(room) == FALSE) {
                sprintf(buf, "Room #%d doesn't exist.\r\n", room);
                send_to_char(buf, ch);
                return;
        }

        num_of_rooms--;

        CREATE(temp, struct room_data, num_of_rooms);

        for(i = 0, y = 0; i < num_of_rooms; i++, y++)
        {
                if (world[i].number != room)
                        temp[y] = world[i];
                else
                        y--;
        }

        CREATE(world, struct room_data, num_of_rooms);

        for(i = 0; i < num_of_rooms; i++)
                world[i] = temp[i];

        sprintf(buf, "Room #%d deleted.\r\n", room);
        send_to_char(buf, ch);
}

int is_room( int room_num )
{
        int i, found = FALSE;
        for(i = 0; i < num_of_rooms; i++)
        {
                if (world[i].number == room_num)
                        found = TRUE;
        }

        return found;
}

Any help would be appreciated,

Cheers,
