Creational Design Patterns in Modern C++ - Multiple Actors - Part III

The video tutorial discusses modifications to the actor pool to support various actor types, highlighting the design issue of tight coupling and the violation of the open-closed principle. It introduces the factory method design pattern to decouple the actor pool from concrete classes. The tutorial explains creating a struct to store actor info and creator functions, modifying functions for acquiring and releasing actors, and registering creators using lambda expressions. The new implementation allows for future flexibility without modifying the actor pool.
