python实现简单的我的世界

不知道大家在编程（不管是c++,python,java。。。）时有没有突发奇想自己能不能编一个我的世界，但不会编，直接给代码：

import pygame
from ursina import *
from ursina.prefabs.first_person_controller import FirstPersonController

app = Ursina()
a = [color.white, color.gray, color.green, color.gray, color.blue, color.gold, color.brown, color.lime, color.green,
     color.brown]

asd = 2
pygame.event.get()


class Hand(Entity):
    def __init__(self):
        super().__init__(
            parent=camera.ui,
            model="cub
