获取 Pygame 键盘输入并检查它是否是数字 [英] Getting Pygame keyboard input and check if it's a number

问题描述

我正在尝试使用 Pygame 使用以下命令获取键盘输入:

I am trying to get keyboard input using Pygame using this command:

if event.type == pg.KEYDOWN:
    # ADD KEYBOARD EVENTS
    keys = pg.key.get_pressed()

我想检查按下的按钮是否代表数字，我已经知道如何使用 try/except 命令检查字符串是否代表数字，但是，在我的代码中 keys 不是字符串，它是一个巨大的元组 - 我不知道如何以有效的方式获取它，因为每次我在互联网上查看如何获取键盘输入时，他们都需要等同于 键 到诸如 pygame.pygame.K_LEFT 之类的东西，我不想为每个数字以及数字键盘(右侧)中的每个数字都这样做.

I want to check if the button pressed represents a number, I already know how to check if a string represent a number using try/except command, but, in my code keys is not a string, it is a huge tuple - and I don't know how to get it in an efficient way because every time I look in the internet on how to get keyboard input, they need to equate keys to something like pygame.pygame.K_LEFT and I don't want to do this for each number and furthermore every number in the number-pad (right side).

有没有一种有效的方法来确定用户是否点击了一个数字?谢谢！

Is there an efficient way to determine if a user clicked on a number? Thanks!

推荐答案

pygame.key.get_pressed() 返回一个包含所有键盘按钮状态的列表.这不是为了获取键盘事件的键.按下的键可以从 key 属性中获取rel="nofollow noreferrer">pygame.event.Event 对象:

pygame.key.get_pressed() returns a list with the state of all keyboard buttons. This is not intended to get the key of a keyboard event. The key that was pressed can be obtained from the key attribute of the pygame.event.Event object:

if event.type == pg.KEYDOWN:
    if event.key == pg.K_a:
        # [...] 

unicode 包含一个作为完全翻译字符的字符串:

unicode contains a single character string that is the fully translated character:

if event.type == pg.KEYDOWN:
    if event.unicode == 'a':
        # [...] 

另见 pygame.key.
