Python 3.x Flappy Bird pygame基地未定义

Python 3.x Flappy Bird pygame基地未定义,python-3.x,pygame,flappy-bird-clone,Python 3.x,Pygame,Flappy Bird Clone,我目前正在完成Python 3.8中的一个Flappy Bird游戏,该游戏将由一个AI来玩,AI将自己学习如何玩游戏,并从以前的错误中改进自己,直到它“不可战胜”为止。我很快就要完成了,但我的代码中有一个错误: name错误:未定义名称“base” 这个错误在我之前的测试中没有出现。我查看了所有在游戏中提到基础的代码,但仍然没有发现任何错误。游戏代码如下: import pygame import neat import time import os import random pygame

对于这么长的代码,很抱歉,您可能需要按Ctrl+F来查找代码中基本元素的所有位置,我提前感谢您的帮助


注:底部是游戏的地板。

您没有在
main()中创建
Base
的实例。e、 g:

def main(基因组,配置):
# [...]
基数=基数(0)

我们不需要检查您的所有代码,完整的错误消息本身会提到准确的行号和行号。因此,请将其添加到您的帖子中。完整的回溯提供了比您想象的有用得多的信息。在
main()
中没有变量
base
base
draw\u window()
中定义,因为它是一个参数,但在
