pygame对象的错误是不可迭代的

Question

#campaign module for blunt wars

import pygame

import time

import sys

pygame.init()

size = [400, 400]

width = size[0]

height = size[1]

#colors

black = (0,0,0)

white = (255,255,255)

red = (200,0,0)

green = (0,200,0)

blue = (0,0,255)

bright_red = (255,0,0)

bright_green = (0,255,0)

#end colors

screen = pygame.display.set_mode((size), pygame.RESIZABLE)

pygame.display.set_caption('Blunt Wars - Campaign')

clock = pygame.time.Clock()

#updates screen res

for event in pygame.event.get():

    if event.type ==pygame.VIDEORESIZE:

        screen = pygame.display.set_mode((event.w, event.h), pygame.RESIZABLE)

text = pygame.font.SysFont('Arial', 30)

def text_objects(text, font):

    textSurface = font.render(text, True, black)

    return textSurface

def button(msg,x,y,w,h,ic,ac,action=None):

    mouse = pygame.mouse.get_pos()

    click = pygame.mouse.get_pressed()

    if x+y > mouse[0] > x and y+h > mouse[1] > y:

        pygame.draw.rect(screen, ac,(x,y,w,h))

        if click[0] == 1 and action != None:

            action()

    else:

        pygame.draw.rect(screen, ic,(x,y,w,h))

        smallText = pygame.font.Sysfont('Arial',20)

        textSurf, TextRect = text_objects(msg, smallText)

        textRect.center = ( (x+(w/2)), (y+(h/2)) )

        screen.blit(textSurf, TextRect)

def intro():

    intro = True

    while intro:

        for event in pygame.event.get():

            #print(event)

            if event.type == pygame.QUIT:

                pygame.quit()

                quit()

                #import Blunt_Wars

因此，这是我的整个程序，我试图制作一个主菜单，但是当我运行此代码时，出现此错误：

textSurf, textRect = text_objects("Blunt Wars - Campaign", header)

TypeError: 'pygame.Surface' object is not iterable.

我不知道为什么要这样做，但是如果有人可以帮助我，将不胜感激。

调查一下：def text_objects(text, font):    textSurface = font.render(text, True, black)    return textSurfacetextSurf, textRect = text_objects("Blunt Wars - Campaign", header)text_objects()返回结果font.render()是一个pygame.Surface实例。这不是迭代的，这就是为什么您的拆箱无法正常进行的原因...
