ScrollObjects are Class Templates. They provide many functions such as OnCreate, Update, OnCollide etc.
If we had a scroll object class file, say: Spaceship.cpp, and it had been included and properly bound, We could create an instance of our object with:
ScrollObject *ship = CreateObject("Spaceship");
This much is all pretty standard. But when you extend the Spaceship class to support extra methods, using ScrollObject as a class type will not give access to the new methods.
In order to create an instance of Spaceship, which gives access to all your new methods, you need to use:
Spaceship *ship = CreateObject<Spaceship>("Spaceship");
From here you can use other methods like:
ship->Land();
