    newb question

    Ok. I ll note post all the code not to make things complicated. I have two classes:
    Code:
    class Character
    {
        ...
        Weapon rightHand;
        ...
    };
    
    class Weapon : public Item
    {
        ...
    }
    I want to do this:
    Code:
    Character newb;
    Weapon w;
    newb.rightHand = w;
    If I undestand correctly newb.rightHand will have a copy of w. Thus you will have double the memory for the a Weapon object. Is that bad programming? Would it make more sense having a pointer that will point to the object Weapon instead of copying the whole object?

    I suppose it depends on what is going on within the Weapon function. Generally speaking this seems fine. If you are worried about the level of overhead in copying over a weapon then why not just use a (smart) pointer? Can I assume that rightHand is a public member of Character?

    I'd suggest using a Factory.

    You could probably also do:

    Code:
    Character newb;
    newb.righthand = Weapon();
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
