title: Python Pygame letter Keystrokes not registering?
body: <p>My problem is that whenever I use a letter for a keystroke it does not work. The code worked when I changed the keystrokes to arrow keys but didn't work if I tried to use WASD. I have tried replacing the variables and many other things but it still does not work.</p>
  <p>Here is my code that works:</p>
  <pre><code>import pygame
  import os
  
  pygame.init()
  
  width = 1200
  height = 800
  FPS = 60
  
  # Player 1
  playerImg1 = pygame.image.load('spaceship1.png')
  playerX1 = 200
  playerY1 = 370
  playerX_change1 = 0
  playerY_change1 = 0
  
  def player1(x1, y1):
      window.blit(playerImg1, (x1, y1))
  
  # Player 2
  playerImg2 = pygame.image.load('spaceship2.png')
  playerX2 = 800
  playerY2 = 370
  playerX_change2 = 0
  playerY_change2 = 0
  
  def player2(x2, y2):
      window.blit(playerImg2, (x2, y2))
  
  # gameLoop
  running = True
  clock = pygame.time.Clock()
  while running:
  
      clock.tick(FPS)
      for event in pygame.event.get(): 
          if event.type == pygame.QUIT:   
              running = False
      # Keystrokes
      if event.type == pygame.KEYDOWN:
          if event.key == pygame.K_LEFT: #left
              playerX_change1 = -5
          if event.key == pygame.K_RIGHT: #right
              playerX_change1 = 5
      
      if event.type == pygame.KEYUP:
              if event.key == pygame.K_RIGHT or event.key == pygame.K_RIGHT:
                  playerX_change1 = 0
      
      playerX1 += playerX_change1
      if playerX1 &lt;= 0:
          playerX1 = 0
      elif playerX1 &gt;= 400:
          playerX1 = 400
  
      window.blit(bg,(0,0))
  
      player1(playerX1, playerY1)
      player2(playerX2, playerY2)
     
      pygame.display.update()
