builtins.AttributeError: 'Screen' 对象没有属性 'blit'

Question

我对 pygame 很陌生，我正在尝试为学校项目制作游戏，但我正在努力获得一个我称之为 Enemy 的精灵课程。工作，我希望我的最终产品在屏幕上有一个精灵，然后在它“死亡”时被替换，但我目前正在努力完成一项工作

menuScreen.blit(self.image, self.rect)

builtins.AttributeError: 'Screen' object has no attribute 'blit'

我不知道我还想使用什么，我尝试过 .draw 和其他一些东西，但没有任何效果

import pygame

colours = {"White" : (255, 255, 255), "Black" : (0, 0, 0), "Red" : (255, 0, 0), "Blue" : (0, 0, 255), "Green" : (0, 255, 0)}
