为什么这个图像不会移动？

Question

据我所知，当我按下箭头键/WASD时，这个程序应该正在移动图像，我不知道为什么它不移动。 为了加快阅读速度，我可以解释它是什么。我首先定义了一些东西，只是为了方便起见，然后在我的while循环中，我开始使用getkey，我设置它，当你按下箭头键时，它会将屏幕涂成白色，然后在x/y上+/-10，然后它会在新的位置重新绘制图片，但是出于某种原因，它只是不执行那些If语句之后的任何代码

import pygame
import sys
import os
import curses
def print_there(x, y, text):
     sys.stdout.write((x, y, text))
     sys.stdout.flush()
pygame.init()
bckgrnd_clr = 'gray95'
x,y=0,0
width = 1280
height = 704
screen = pygame.display.set_mode((width,height))
GameImage = pygame.image.load("Images/stage.png")
Player = pygame.image.load("Images/Knight.png")
Blank = pygame.image.load("Images/Blank.png")
pygame.display.set_caption("Zackarys Game")
screen.blit(GameImage, (0,0))
screen.blit(Player, (y,x))
pygame.display.update()
FPS = 30
clock = pygame.time.Clock()
white = [255 , 255, 255]
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
          if event.key == pygame.K_LEFT or event.key == ord('a'):
               screen.fill(white)
               x = x - 10
               screen.blit(GameImage, (0,0))
               screen.blit(Player, (y,x))
          if event.key == pygame.K_RIGHT or event.key == ord('d'):
               screen.fill(white)
               x = x + 10
               screen.blit(GameImage, (0,0))
               screen.blit(Player, (y,x))
          if event.key == pygame.K_UP or event.key == ord('w'):
               screen.fill(white)
               y = y - 10
               screen.blit(GameImage, (0,0))
               screen.blit(Player, (y,x))
          if event.key == pygame.K_DOWN or event.key == ord('s'):
               screen.fill(white)
               y = y + 10
               screen.blit(GameImage, (0,0))
               screen.blit(Player, (y,x))
          if event.key == pygame.K_ESCAPE:
               pygame.display.quit()
               pygame.quit()
               sys.exit()
               running = False

请尽快告诉我

我已经修正了你的密码。我不知道“诅咒”模块的作用是什么。问题是您只更新了一次显示（这将禁用动画）。另一个问题是，您试图仅在按下事件键时闪烁图像，如果您需要定期更新显示，这将是一个问题。这是更新的代码（我也修复了你的x和y）
