Question

我目前正在学习Pygame游戏开发教程中的代码： https://www.youtube.com/watch?v=fcryHcZE_sM
我已经将代码完全复制到Pycharm中，我相信它应该可以工作。

#Pygame Sprite Example
import pygame
import random
import os


WIDTH = 360
HEIGHT = 480
FPS = 30

#Colours
BLACK = (0, 0, 0)
WHITE= (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)


# set up assets folders
game_folder = os.path.dirname(__file__)
img_folder = os.path.join(game_folder, "img")


class Player(pygame.sprite.Sprite):
    # sprite for the player
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load(os.path.join(img_folder, "p1_jump.png")).convert()
        self.image.set_colourkey(BLACK)
        self.rect = self.image.get_rect()
        self.rect.center = (WIDTH / 2, HEIGHT / 2)

    def update(self):
        self.rect.x += 5
        if self.rect.left > WIDTH:
            self.rect.right = 0

 #initialise pygame and create window
 pygame.init()
 pygame.mixer.init()
 screen = pygame.display.set_mode((WIDTH, HEIGHT))
 pygame.display.set_caption("My Game")
 clock = pygame.time.Clock()

all_sprites = pygame.sprite.Group()
player = Player()
all_sprites.add(player)

#Game Loop
running = True
while running:
    #keep loop running at right speed
    clock.tick(FPS)
    #Process Input/Events
    for event in pygame.event.get():
        #check for closing window
        if event.type == pygame.QUIT:
            running = False

    #Update
    all_sprites.update()

    #Draw/Render
    screen.fill(BLUE)
    all_sprites.draw(screen)
    # *after drawing everything, flip the display*
    pygame.display.flip()

pygame.quit()

当我运行它时，它给了我这个错误：

C:\Users\George\PycharmProjects\app\venv1\Scripts\python.exe "C:/Users/George/Documents/School/Year 12/IT/Coursework/SpriteExample.py"
Traceback (most recent call last):
  File "C:/Users/George/Documents/School/Year 12/IT/Coursework/SpriteExample.py", line 46, in <module>
    player = Player()
  File "C:/Users/George/Documents/School/Year 12/IT/Coursework/SpriteExample.py", line 28, in __init__
    self.image = pygame.image.load(os.path.join(img_folder, "p1_jump.png")).convert()
pygame.error: Couldn't open C:/Users/George/Documents/School/Year 12/IT/Coursework\img\p1_jump.png

Process finished with exit code 1

在教程视频中，这家伙正在使用Mac，而我正在使用Windows笔记本电脑（运行Windows 7）。我试过在网站上进行研究，但是找不到任何具体的错误。我还尝试将类Player的初始化中的代码更改为：

game_folder = os.path.dirname(os.path.abspath(__file__))
img_folder = os.path.join(game_folder, "img")
image1 = pygame.image.load(os.path.join(img_folder, "p1_jump.png" ))


class Player(pygame.sprite.Sprite):
    # sprite for the player
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = image1.convert()
        self.image.set_colourkey(BLACK)
        self.rect = self.image.get_rect()
        self.rect.center = (WIDTH / 2, HEIGHT / 2)

它仍然无效。

如果您将其命名为my_path.py或类似名称，然后将其放置在documents文件夹中并运行它，则将其命名为my_path.py。它将帮助您看到sprite2.py文件应该位于documents文件夹中，并且您需要在文档中有一个名为“ img”并包含“ png”文件的子文件夹。然后游戏应该运行正常。因此，game_folder实际上是“文档文件夹”，而img_folder是文档中的img。我希望可以更清楚一点，如果您在另一个文件夹中有游戏，则可以修改sprite2.py之上或之内的代码

game_folder = os.path.dirname(__file__)
print(game_folder)
img_folder = os.path.join(game_folder, "img")
print(img_folder)

pygame.image.load（）无效
