Problems with cin and GetAsyncKeyState

Lemme see if I got the code correctly.

The class baseobject is like a class for all the types of items that the player can carry in his/her inventory. virtual void Describe would have the description of the item. virtual bool isWeapon() determines if the item is a weapon and is false by default.

The class weapon is like a class for the weapon type of item. isWeapon() would be true because it is a weapon.

Parts I don't get :
What is shortDesc and longDesc supposed to mean?
useWeaponOn means equip or don't equip? or does it mean something else?
No idea whats a virtual data type yet =(

Yup, that's pretty much it. Although, my thoughts was that baseobject::Describe would do something like this, which hopefully answers your question below as well:

Code:

---

void baseobject::Describe(bool brief)
{
  if (brief) cout << shortDesc;
  else cout << longDesc << endl;
}

Let's start with virtual - it essentialy means "use the object itself to find the function". Without virtual, the compiler uses the object-type of the current variable to find the function. With virtual, the object holds a pointer to the function [usually in the form of a vtable to be precise]. The purpose of this is that we can then use a baseobject pointer to hold an object [e.g. a vector of baseobject pointers], but the list could hold weapons and other derived objects that have different properties.

So, for example:

Code:

---

vector<baseobject> stuff;
baseobject *pillow = new baseobject("pillow", "A soft pillow - it looks so comfortable that you may want to rest your head on it right now");
weapon *axe = new weapon("axe", "A very sharp looking axe", 0.5);

stuff.push_back(pillow);
stuff.push_back(axe);

...
for(int i = 0; i < stuff.Size(); i++)
{
  if (stuff[i]->isWeapon()) {
      cout << "You can use ";
      stuff[i]->Describe(true);
      cout << "as a weapon";
  }
}

---

For the above to work, we obviously need isWeapon to be called on the weapon class for axe to be recognized as a weapon.

My idea of "useWeaponOn" was more like when you say "Fight monster with axe", it would do "axe->useWeaponOn(monster)".

I think the description stuff is clarified by the examples.

Ahh OK I can roughly get it. Read up on the whole Cprogramming.com tutorial before continuing would be a good idea?
