godot-2d-jrpg-combat VS godot-open-rpg

So I'm trying to make a turn-based jrpg prototype based on this open project below. Basically, when I called the function _play_turn(P1), P1 node goes into this coroutine function and when you "completed" selecting action and target, P1 can act and get outside of this coroutine (pic below is just a sample, not all the codes in real script) https://github.com/GDQuest/godot-2d-jrpg-combat

godot also has a similar system that uses the Resource type. There's a great example putting them to use in a system from gdquest here: https://github.com/GDQuest/godot-2d-jrpg-combat

I had no idea how to start implementing a combat system so I started working on top of the GDquest's 2D JRPG Combat (https://github.com/GDQuest/godot-2d-jrpg-combat)

As I mentioned before, most of the tutorials out there will expect that base level of programming knowledge, so you're probably out of luck there. I did a search and found that GDQuest have this project repository and it has the feature you want. You can download the source code for free and read through it, but I couldn't find any tutorial that walks through the code and how it works.

Looking for save game tutorials lead me to this by gdquest that seemed the most comprehensible to me.

https://github.com/GDQuest/godot-open-rpg here is one in 2D. You could use it as a guide.

I think the GDQuest Open RPG template/demo is a pretty good demonstration of the concept. Many of the scripts in there don't explicitly declare a global class for themselves, and they are only relevant to, and used by, a particular subset of scripts/scenes which are in nearby/wrapping directories. There isn't just one big mega assets folder that stores everything in a flat list, etc.
