Python事件没有Key属性

Question

我正在尝试为我的角色移动创建一个程序。这是我的代码

while True:
   for event in pygame.event.get():
       if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == KEYDOWN:
            if(event.key == K_RIGHT):
            playerPos[0] +=1
    if (event.key == K_RIGHT) and playerPos[0] < MAPWIDTH -1:
        playerPos[0] =+ 1

这是错误

Traceback (most recent call last):
  File "H:\python things\firstgame.py", line 90, in <module>
if (event.key == K_RIGHT) and playerPos[0] < MAPWIDTH -1:
AttributeError: 'Event' object has no attribute 'key'

如果有人遇到这篇文章并遇到同样的问题，我修复了我的错误并最终解决了这个问题。添加评论以帮助其他人理解

while True:
    #get all the user events
    for event in pygame.event.get():

        #if user wants to quit
        if event.type == pygame.locals.QUIT:
            #and the game close the window
            pygame.quit()
            sys.exit()

        #if a key is pressed
        elif event.type == pygame.locals.KEYDOWN:
            #if right arrow is pressed
            if event.key == K_RIGHT and playerPos[0] < MAPWIDTH - 1:
                #change player's x postion
                playerPos[0] +=1
            if event.key == K_LEFT and playerPos[0] > 0:
                #change player x position
                playerPos[0] -=1
            if event.key == K_UP and playerPos[0] > 0:
                #change players x position
                playerPos[1] -=1
            if event.key == K_DOWN and playerPos[1] < MAPHEIGHT -1:
                #change player x position
                playerPos[1] += 1
