錯誤：無法打開圖像

Question

我正在研究基於時間的pygame移動程序。我一直收到這個錯誤。

Traceback (most recent call last): 
    File "C:\Documents and Settings\Mohammad Raza\Desktop\Python  
Scripts\TimeBasedMovement.py", line 11, in <module> 
    background = pygame.image.load(background_image_filename).convert() 
error: Couldn't open Wolf.jpg 

我想也許我刪除了圖像，但我檢查了圖像並沒有刪除。它被保存爲名稱「Wolf」並存儲爲JPEG圖像。

以下是整個代碼。

background_image_filename = 'Wolf.jpg' 
sprite_image_filename = 'Cartoon.jpg' 

import pygame 
from pygame.locals import * 
from sys import exit 

pygame.init() 
screen = pygame.display.set_mode((640,480),0,32) 

background = pygame.image.load(background_image_filename).convert() 
sprite = pygame.image.load(sprite_image_filename) 

clock = pygame.time.Clock() 

x = 0. 
speed = 250 

while True: 

    for event in pygame.event.get(): 
     if event.type == QUIT: 
      exit() 

    screen.blit(background,(0,0)) 
    screen.blit(sprite,(x,100)) 

    time_passed = clock.tick() 
    time_passed_seconds = time_passed_seconds/1000.0 

    distance_moved = time_passed_seconds * speed 
    x += distance_moved 

    if x > 640.: 
     x -= 640. 

    pygame.display.update() 

Answer 1

還要確保圖像在當前工作目錄中。

fullname = os.path.join('data', name) 
    image = pygame.image.load(fullname) 

Answer 2

而且它應該是

time_passed_seconds = time_passed/1000.
