制作游戏，无法导入背景图像或精灵

Question

我是一个新的程序员，试图做一个平板战斗2D滚动游戏，我已经创建了我的背景和一个角色精灵，但我试图blit他们进入我的代码，但我得到一个错误，说

The first argument needs to be pygame.Surface()

当我这么做的时候，它就会告诉我

ValueError: size needs to be (int width, int height)

我已经研究了很多关于这个的问题，尝试了很多方法，但都没有效果。请帮忙

import pygame
pygame.init()

global X, Y, gameBackground
bg = [pygame.image.load("pygame/gameBackground.png")]
char = [pygame.image.load("pygame/characterStandingRight.png")]
#I have my .png files in a folder named "pygame" inside of my general program folder
windowWidth = 1366
windowHeight = 697
Width = 40
Height = 64
X = 5
Y = windowHeight - (Height + 5)
tick = 30
run = True

def redrawGameWindow():
    window.blit(pygame.Surface(bg), (0, 0)) #draws Window Background
    window.blit(pygame.Surface(char), (X, Y)) #draws Character Sprite
    pygame.display.update()
#above is where I have my errors of "pygame.Surface" and "(int width, int height)"

window = pygame.display.set_mode((windowWidth, windowHeight))
pygame.display.set_caption("Game")

while run:
    pygame.time.delay(tick)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    #other game code which controls character movement functions
    redrawGameWindow()

pygame.quit()
quit()

我想你是把列表放到blit中，这会产生一个错误。应该是：

window.blit(bg[0], (0, 0)) #draws Window Background
