What you can do is this:
*** Source Snippet Removed ***
This allows you to access the members using dot operators ( theVec.x ), arrays ( theVec[2] ) AND typecast it to a float pointer.
class Vector3{private: float x, y, z;public: float &X() { return x; } const float &X() const { return x; } float &Y() { return y; } const float &Y() const { return y; } float &Z() { return z; } const float &Z() const { return z; } float &operator[]( int i ) const { return ( float & )*( &x + i ); } operator float *() { return &x; }};
