Will the course cover undo Function?

Thank you for this really amazing perfect course, well-orginized focusing on clean code, giving as much explaining and a variety of ways to handle situations and keeping in mind that this game should be scalable and expandable, all these make it the best course I have ever enrolled in
I am just wondering if we will handle undo Functions in this course because I think they are crucial to strategy (puzzle) games like this one, is this approach best handeled using The Command pattern, or what is your thought about it, I haven’t finished the course yet but I think that this was the suitable place to add this function and I can’t see it there so I guess it’s not covered here, Could you add this to the course or to a separate youtube video , That would very great and thanks for the great effort

That is certainly possible but not something covered in the course.

For simple actions it’s pretty easy, for a move action just move back to where it started the action.
For other actions, like Shoot, it becomes quite a bit more complex. If an enemy dies you need to handle reviving that enemy, re-setting it’s health, etc.

So it’s not an easy task but it’s certainly doable, something like the Command pattern could be good but again it becomes quite a bit more complex since the action impacts external things (like the shot unit)

Thanks for answering
yeah exactly we need to keep track of every action taken to be able to undo it .
Looking forward to try it at out

I have to disagree with the notion that an undo function would be crucial to any game. As a player, I feel that it takes away from the challenge, and feels cheaty. For instance, the Forza Motorsport series on Xbox has a “rewind” feature, very similar to an undo function, that I always turn off. It always infuriated me when I would forget and accidentally hit the button for it with a clumsy finger. So, personally, even though it’s definately doable, as it has been done before, I don’t feel it’s worth the time. Just my two cents. I guess a better point would be to know your player base, and what they want in a game. At least in Forza I had the option to turn it off.
