changes, let’s give more specific names to our objects (Plane and Boat), and make sure we’re inheriting publicly IGameObject. IGameObject Plane Boat ...Updated ‘function’ to create objects (1/4) 52 implementation details for derived class ● We could extend our enum class creatively as well ■ e.g., PLANE_IN_AIR ● This handles constructing the same types with different parameters or setup functions great way to hide implementation details for derived class 63 Updated with another object type (PLANE_IN_AIR) that we can createThe Factory Method (5/5) The Factory Method pattern provides a generalized
