到目前为止,这是完成我的第一个游戏的最后一步(除了背景音乐,我已经知道了),但是,当我尝试添加菜单图像时,python抱怨如下错误:道奇.py,第84行 屏幕.blit(菜单位置、菜单图像) TypeError:参数1必须是pygame.表面,而不是列表)我有点迷路了,下面是我的游戏代码:

        pygame.display.update()

        # Check if any of the baddies have hit the player.
        if playerHasHitBaddie(playerRect, baddies):
            if score > topScore:
                topScore = score # set new top score
            break

        mainClock.tick(FPS)

    # Stop the game and show the "Game Over" screen.
    gameOverSound.play()
    screen.blit(gameover_image, gameover_position)
    pygame.display.update()
    waitForPlayerToPressKey()

    gameOverSound.stop()   

谁能帮我一下吗?我将不胜感激。这是我运行游戏时唯一的问题。你知道吗

复制错误的代码摘录:

WINDOWWIDTH = 1280
WINDOWHEIGHT = 768
screen = pygame.display.set_mode((WINDOWWIDTH, WINDOWHEIGHT))
pygame.init()
background_image = pygame.image.load("background.png").convert()
menu_image = pygame.image.load("Menu.png").convert()

# Set positions of graphics
background_position = [0, 0]
menu_position = [0, 0]

# Copy image to screen
screen.blit(background_image, background_position)

# show the "Start" screen
screen.blit(menu_position, menu_image)


for event in pygame.event.get():
    if event.type == QUIT:
        pygame.quit()
        sys.exit()
    pygame.display.update()

如果没有代码其余部分的杂音,很明显

screen.blit(menu_position, menu_image)

第一个参数是列表[0,0],第二个参数是曲面。你知道吗

signature of Surface.blit是不同的。你知道吗

您应该反转这两个参数来解决问题(如错误消息所述)。你知道吗

免责声明 我没有运行这个示例,您至少需要导入所需的模块并重新检查缩进。你知道吗

@MattDMo的暗示是纯金的,如果你能接受的话。如果没有它,我就不会费心回答你的问题,因为有很多代码要读,错误是微不足道的(我所做的最严重的错误通常是微不足道的)。你知道吗
