Thank you so much! I really enjoy this type of content. Keep up the great work!

LOVE THIS! I tried to read through this from the book, but when I hit "Encapsulate a request as an object, thereby letting users parameterize clients with different requests, queue or log requests, and support undoable operations." I just checked out. This was a GREAT example of showing the concept in an easy to understand manner. :-)

As a neophyte programmer, it is good to see tutorials tackling programming patterns especially for the GDScript of Godot Game Engine. Aside form the Observer and the State Patterns which I have been incorporating with my knowledge using the Godot, this tutorial would be my first encounter with the Command Pattern. Hope to see more about this pattern and other patterns that I have yet to encounter or even heard off. Thank you.

As always, thanks. I like these non ARPG videos too!

Thank you for a great tutorial. I have one question though. I'm trying to use the command pattern for my game, but I used resources instead of node. Which way would be better?
