我在游戏中一直致力于键检测，但我得到的一个问题是我收到了这个错误。
Traceback (most recent call last):

if event.key == pygame.K_p:
AttributeError: 'Event' object has no attribute 'key''
我试图缩进以尝试解决错误，但这没有任何区别。解决此错误的解决方案是什么？我也查看了其他问题，并尝试了他们的建议，但我无法解决问题。
以下是使用和已经删除的定义。

答案 0 :(得分：3)
涉及event.key的所有测试都应该在elif event.type == pygame.KEYDOWN:开始的块内 - 否则它只是尝试为所有事件获取属性key - 并且任何与键盘无关的事件（如鼠标移动或计时器）都没有key属性。
只需重新缩进程序，以便只在事件类型为“KEYDOWN”时才执行“键”测试，并且它应该有效。
答案 1 :(得分：2)
因为你的缩进是错误的。
见下正确的代码：
elif event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
player._vx = -3
if event.key == pygame.K_p:
print('paused')
pygame.display.update()
if event.key == pygame.K_r or not player.alive():
print('gameover')
pygame.display.flip()
elif event.key == pygame.K_RIGHT:
player._vx = 3
Enemy.go_left()
elif event.key == pygame.K_UP:
player.jump()
