AttributeError:“事件”对象没有属性“键”

标签: python pygame attributeerror

运行代码时,我收到以下错误消息。

Traceback (most recent call last):
  File "C:/Users/user/PycharmProjects/MyDevWork/PygamesRelated/game_1.py", line 29, in <module>
    elif event.key == pygame.K_s:
AttributeError: 'Event' object has no attribute 'key'

这是我的代码:

import pygame

pygame.init()

screen = pygame.display.set_mode((720, 480))
clock = pygame.time.Clock()
FPS = 60

BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

rect = pygame.Rect((0, 0), (32, 32))
image = pygame.Surface((32, 32))
image.fill(WHITE)

while True:
    clock.tick(FPS)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            quit()

        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_w:
                rect.move_ip(0, -2)
        elif event.key == pygame.K_s:
            rect.move_ip(0, 2)
        elif event.key == pygame.K_a:
            rect.move_ip(-2, 0)
        elif event.key == pygame.K_d:
            rect.move_ip(2, 0)

screen.fill(BLACK)
screen.blit(image, rect)
pygame.display.update()

我正在使用python 3.7和Pycharm。

如上所述,您的缩进是这里的问题。检查event.key的所有内容都应位于KEYDOWN检查的“内部”。将while循环更改为:

while True:
    clock.tick(FPS)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            quit()

        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_w:
                rect.move_ip(0, -2)
            elif event.key == pygame.K_s:
                rect.move_ip(0, 2)
            elif event.key == pygame.K_a:
                rect.move_ip(-2, 0)
            elif event.key == pygame.K_d:
                rect.move_ip(2, 0)
