VehicleGameObject pVehicleObj = Find_My_Vehicle();
GameObject* pObject = dynamic_cast<GameObject*>(pVehicleObj);
Or...
GameObject* pObject = dynamic_cast<GameObject*>(Find_My_Vehicle());
Or...
GameObject* pObject = (GameObject*)Find_My_Vehicle();
(PS: If you didn't already figure it out, VehicleGameObject *is* a GameObject, since it's a derived class)
(PPS: Yes, I know dynamic casting a subclass to its superclass is redundant since it's always going to succeed, just illustrating my point  )

VehicleGameObject is derived from GameObject.
This means VehicleGameObject is everything GameObject is +more.
The code for this would be
class VehicleGameObject : public GameObject{...};
*note: In the scripts.dll source, there might be an inheritance in between or multiple inheritance. I did not check this code so it may look a bit different in the real source. This does however reflect how VehicleGameObject is a GameObject
You can ofcourse have this stacked
class X{...};
//Y is X +more
class Y : public X{...};
//Z is Y +more
class Z : public Y{...};
As Z derives from Y, and Y from X, Z is also an X.
Or multiple
class A{...};
class B{...};
class C : public A, B{...};
C is both an A and B, BUT A is not a B and B is not an A in this case.

Then you also get things like access modifiers and the virtual keyword that all affect inheritance behavior, but you can search that up when you need it
