This is a project of a tutorial which is made for the game function about Godot. So there is anything you want especially if you were not the Chinese Speaker, because I upload the tutorial on bilibili, a famous video stream platform in China.
It's a tutorial to talk about how to realize the most fundenmental function in the card game -- the card effect combined the CardStateMachine with Operator of HandCard. Maybe my speaking still confuses you. Let me take the example as below: You can click, drag, and release the card. And the cards is arranged like a curve?
But if you were really interested about the tutorial, you can check the video below this embeded in lots of chinese characters you can't understand as a non-Chinese Speaker.
