I'm having a bit of trouble with this. I'm creating a cute little text adventure game for practice, so I can learn the basics of coding in C++.

I decided to use a vector for player inventory. It works great. It's a vector of objects, and I can put in or take out objects, or create a list of them for the "inventory" command, and it all works great.

But I tried to do the same thing for my rooms, so they could have their own "inventories", and it didn't work. The only way I can think of that these two vectors are different is that one is contained in an object and one isn't.

Specifically, I tossed this line into my Global Variables section:

vector<Object> player_inventory;

"Object" is a class I've defined for objects in the game environment. It contains some basic data, like their name, weight, and description.

When I run my command to list the player's inventory, I call this function:

int Inventory_List()
{
    cout << "\nYou are carrying:\n";
    if (player_inventory.size() == 0) {cout << "\nNothing\n";};  //checks whether there are no objects in the player's inventory
    if (player_inventory.size() > 0)
    {
       int n;
       n = player_inventory.size();
       do 
        {
                                n--; // this is necessary because the elements in the vector are numbered starting with 0
                                cout << endl << player_inventory[n].title;
                                
        } while (n != 0);
        cout << endl << endl;
    };  
}

And it works fine.

So, since "cout << player_inventory[n].title" successfully outputted the title of an object in the player_inventory vector, I tried to use identical code to output the title of objects in the room's inventory:

cout << Room_001.room_contents[n].title

But this code returns nothing. It's basically identical to my player inventory code, but I've changed the names. Everything is declared and I get no compilation errors. I've added objects into the room_contents vector. If I add those same objects to the player inventory, they'll list just fine.

So the only difference I can think of is that my player_inventory vector is a global vector, but my room_contents vector is inside a "Room" object. Should that really make a difference?

I'm sorry if my code snippits are a bit disjointed, but I think you'll get the jist.
