SOLVED!!!! c++ how do I nest a class?
Author
So there is no way of doing it whereby it would be able to access them with m_Parent.m_Sprites rather than m_Parent->m_Sprites ?

Sure there is, use a reference.
class World { ... m_Sprites;public: //for example main() only class Loader;private: friend class Loader;};class World::Loader { World & m_Parent;public: Loader( World & Parent ) : m_Parent( Parent ) { } void Example () { m_Parent.m_Sprites = ...; ... & Sprites = m_Parent.m_Sprites; Sprites = ...; }};int main () { World MyLittlePlanet; World::Loader Loader( MyLittlePlanet ); Loader.Example();}Quote:Original post by skjinedmjeet
What would the advantage of a nested class over a non-nested class be anyway?
Visual grouping and access control ( you can make a nested class private, and thus unusable outside of the class and it's friends itself ). Minor advantages, but on the flip side I can't think of any disadvantages to the practice.

One advantage is one fewer .h files.
I've got all this working now so thanks all!!!
You aren't required to have just one class in a header file. That's just a matter of preferance and grouping.
