When I debuged it, I noticed that the call to vertex1 = vertex2 calls the copy constructor instead. In the header file I have: //constructors vector3(); vector3( vector3 &v ); vector3(float ix, float iy, float iz); //opera...
Well, I'm trying to avoid using the deprecated DirectInput. But I need, at each "frame" or "iteration" of the game to snatch ALL KEY STATES so that I can act accordingly.

Hi I'm wondering whether there is a way to find out whether a class is a direct base of another class i.e. in boost type trait terms a is_direct_base_of function. As far as I can see boost doesn't see to support this kind of functionality which leads me to think that its impossible with the current C++ standard. The reason I want it is...
