Python pygame 崩溃，修复似乎不起作用

Question

我正在尝试制作一个平台游戏，并且在下面的代码中，我尝试在背景上移动一个图像（'bird.png'）。但是，每次我尝试启动 pygame 时它都会崩溃，甚至没有加载任何图像。我检查了其他页面，但仍然没有解决问题。代码中可能有一些错误，但我无法检查它是否正常工作，因为正如我所说，pygame 不断崩溃。有什么办法可以解决吗？

PS。对不起，如果它有点乱，代码中的法语单词:)

import pygame 
from pygame import *

pygame.init()

TE=[] 

def perso(X):
    X = [0,448]
    while X != [640,0]:
         w=int(input("Déplacement: "))
#Right#
         if w==0:
              if X[1] == 608:
                   print("You can't leave the map")
              else:    
                   X[1] +=  32
                   print(X)     
#Left#
         elif w==1:
              if X[1] == 0:
                   print("You can't leave the map")
              else:
                   X[1] -= 32
                   print(X)     
#Down#  
         elif w==2:
              if X[0] == 456:
                   print("You can't leave the map")
              else:
                   X[0] += 24
                   print(X)     
#Up#
         elif w==3:
              if X[0] == 0:
                   print("You can't leave the map")
              else:
                   X[0] -= 24
                   print(X)
         else:
              print("non valable")
    print("Bravo!")

screen = pygame.display.set_mode((680, 488)) background_image = pygame.image.load("C:/Python34/Scripts/Images & Sounds/background(680x480).jpg").convert()
screen.blit(background_image,[0,0])

character = pygame.image.load("C:/Python34/Scripts/Images & Sounds/bird(40x40).png").convert()
screen.blit(character, (X[0],X[1]))

我运行代码，当 pygame 窗口打开时，它是黑色的，几秒钟后我收到“无响应”消息（对于 pygame 窗口）。但是，w=int(input("Déplacement: ")) 部分似乎在要求输入时起作用。也许这与图像有关？

最简单的游戏循环之一由每次通过循环调用的“更新”序列和“渲染”序列组成。这两个序列都应该花费很少的时间来完成（越快越好）。可能是 Python 内置的 input 函数正在停止“更新”序列并导致游戏崩溃，因为它无法继续循环。

解决这个问题的最简单方法是使用 Pygame 的内置按键输入法。将“渲染”和“更新”序列分开来帮助区分游戏逻辑和图像渲染也是一个好主意。

import pygame 
from pygame import *

pygame.init()

screen = pygame.display.set_mode((680, 488)) 
background_image = pygame.image.load("C:/Python34/Scripts/Images & Sounds/background(680x480).jpg").convert()
character = pygame.image.load("C:/Python34/Scripts/Images & Sounds/bird(40x40).png").convert()

def move(X):
    keys = pygame.get_pressed()
    #Right#
    if keys[pygame.K_RIGHT] != 0:
        if X[1] == 608:
             print("You can't leave the map")
        else:    
             X[1] +=  32
             print(X)     
    #Left#
    elif keys[pygame.K_LEFT] != 0:
        if X[1] == 0:
             print("You can't leave the map")
        else:
             X[1] -= 32
             print(X)     
    #Down#  
    elif keys[pygame.K_DOWN] != 0:
        if X[0] == 456:
             print("You can't leave the map")
        else:
             X[0] += 24
             print(X)     
    #Up#
    elif keys[pygame.K_UP] != 0:
        if X[0] == 0:
             print("You can't leave the map")
        else:
             X[0] -= 24
             print(X)
    else:
        print("non valable")

    return X


def draw(X):
    screen.blit(background_image,[0,0])
    screen.blit(character, (X[0],X[1]))

Running = True
X = [0,448]
while Running:

    # Updated and draw
    X = move(X)
    draw(X)

    # Allow for the user to exit the game
    for i in pygame.event.get():
        if i.type==QUIT:
            Running = False
            exit()

    # End the game if
    if X == [640, 0]:
        Running = False
        exit()
