Question

我正在尝试为我的角色移动时创建一个程序。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'

如果有人遇到这个帖子并遇到同样的问题，我修复了我的错误并最终得到了这个。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

Answer 2

我认为问题是if (event.key == K_RIGHT) and playerPos[0] < MAPWIDTH -1: 在forloop之外，所以事件没有关键属性。

forloop中的事件有一个关键属性，因为pygame.event.get():移动了forloop中的那一行，这应该可以解决你的问题。

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
       elif (event.key == K_RIGHT) and playerPos[0] < MAPWIDTH -1:
            playerPos[0] =+ 1

我还建议你将第87和88行合并为一个这样的 elif(event.type == KEYDOWN) and (event.key == K_RIGHT):

我希望这会有所帮助。

首先，您必须检查事件的类型。在pygame中，只有KEYDOWN和KEYUP事件具有key属性。因此，如果您这样做，它将起作用：

if event.type == event.KEYDOWN:
    if event.key == event.K_RIGHT:
        playerPos[0] += 1

Python事件没有Key属性
