我正在编写一个小型python游戏，而我的某些代码似乎不起作用。看一看：
import pygame

for event in pygame.event.get():

pygame.quit()
是的。。因此错误显示为：
Traceback (most recent call last):
File "C:\Users\aryaat\Desktop\SPython Gaming Project\Uni Mario(A).py", line 163, in <module>
win.blit(turtle_image, (t_x, t_y)) #22222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222222
TypeError: argument 1 must be pygame.Surface, not list
最佳答案
turtle_image不是pygame.Surface对象，但是是pygame.Surface对象的列表：
turtle_image = [pygame.image.load('Sprites/Goomba1.png'), pygame.image.load('Sprites/Goomba2.png'), pygame.image.load('Sprites/Goomba3.png')]
您必须使用索引运算符（例如
turtle_image[0]）从列表中选择一个对象，该对象要“变白”到窗口表面：win.blit(turtle_image[0], (t_x, t_y))
关于python - 参数1必须是pygame.surface，而不是list，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/58629350/
