In this episode I explain what the Command Pattern is and how you can use it. Before I explain what the Command Pattern is I explain what a design pattern is and reference the Gang of Four's original book, Design Patterns. After that, I explain that the Command Pattern is simply a wrapper around executing commands. I then illustrate how this can be used in conjunction with a Command History object to create an undo/redo system, record gameplay sessions, and create instant replays. I describe in detail how you might code this, then I show an actual example that I use in my code to implement undo/redo system.
