Help with the code for the mod for the game

[Kitaec]

Hi guys, could you help me with the code, I'll tell you right away the code is written by a neural network because I don't know how to program at all, in general this is a mini-game of something like an rpg card game, but there is no leveling of the character and cards, I need to fix a couple of bugs, if anyone can help, I'll be grateful I am grateful
