pygame对象的错误是不可迭代的

Question

#campaign module for blunt warsimport pygameimport timeimport syspygame.init()size = [400, 400]width = size[0]height = size[1]#colorsblack = (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 colorsscreen = pygame.display.set_mode((size), pygame.RESIZABLE)pygame.display.set_caption('Blunt Wars - Campaign')clock = pygame.time.Clock()#updates screen resfor 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 textSurfacedef 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。

Answer 1

调查一下：

def text_objects(text, font):

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

    return textSurface

textSurf, 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...
