不确定我做错了什么,我正在遵循有关如何使用 Python 和 PyGame 制作游戏的教程,但收到错误:
pygame.error: Couldn't open resources/images/dude.png
我的代码如下:
import pygame
from pygame.locals import *
pygame.init()
width, height = 640, 480
screen=pygame.display.set_mode((width,height))
player = pygame.image.load("resources/images/dude.png")
while 1:
screen.fill(0)
screen.blit(player, (100,100))
pygame.display.flip()
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
exit(0)
完整的错误消息是:
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'
ALSA lib conf.c:4292:(_snd_config_evaluate) function
snd_func_card_driver returned error: No such file or directory

Traceback (most recent call last):
File "/root/Documents/PyGame/game.py", line 9, in <module>
player = pygame.image.load("resources/images/dude.png")
pygame.error: Couldn't open resources/images/dude.png
使用相对路径代替(这样做总是更好):
import os
current_path = os.path.dirname(__file__) # Where your .py file is located
resource_path = os.path.join(current_path, 'resources') # The resource folder path
image_path = os.path.join(resource_path, 'images') # The image folder path
通过执行此操作,无论您将包含您的文件夹的文件夹移动到何处,.py
文件及其子目录(以及它们包含的任何内容)仍然可以访问,而无需修改代码。
最终代码:
import pygame
import os
from pygame.locals import *
pygame.init()
width, height = 640, 480
screen = pygame.display.set_mode((width, height))
current_path = os.path.dirname(__file__) # Where your .py file is located
resource_path = os.path.join(current_path, 'resources') # The resource folder path
image_path = os.path.join(resource_path, 'images') # The image folder path
player_image = pygame.image.load(os.path.join(image_path, 'dude.png'))
while 1:
screen.fill(0)
screen.blit(player, (100,100))
pygame.display.flip()
for event in pygame.event.get():
if event.type==pygame.QUIT:
pygame.quit()
exit(0)
对所有其他文件使用这种访问方法,您将避免很多问题。
