第一个for循环之后的return似乎是罪魁祸首。你能评论一下然后再试一次吗？
我认为代码应该是这样的：import pygame
from pygame.locals import *
from sys import exit
pygame.init()
screen = pygame.display.set_mode((640,480),0,32)
def create_scales(height):
red_scale_surface = pygame.surface.Surface((640,height))
blue_scale_surface = pygame.surface.Surface((640,height))
green_scale_surface = pygame.surface.Surface((640,height))
for x in range(640):
c = int((x/639.)*255.)
red = (c,0,0)
green = (0,c,0)
blue = (0,0,c)
line_rect = Rect(x,0,1,height)
pygame.draw.rect(red_scale_surface,red,line_rect)
pygame.draw.rect(green_scale_surface,green,line_rect)
pygame.draw.rect(blue_scale_surface,blue,line_rect)
return red_scale_surface, green_scale_surface, blue_scale_surface
red_scale, gre
