In the class _engine I declare the class _npc as npc:

class _engine {

_npc npc;

};

Ok??

And in the class _npc there''s the function npc

And this...:

void _engine::npc.move() {
}

... is the function, but without any code within

perhaps you mean

void npc::move()
{
...

instead of

void _engine::npc.move()
{
...

The class npc is not a member of _engine.
