python - pygame 按键组合(ctrl + 键或 shift + 键)

Question

我有一些发生 keydown 事件的 python 代码，我基本上想知道是否可以同时按下两个键，比如 ctrl+a 或类似的东西。这可能吗，还是我必须找到解决方法？

Answer 1

使用pygame.key.get_mods()获取特殊键的状态，例如 Control 或 Shift。

get_mods()给出一个整数，你必须使用按位运算符将它与常量进行比较，如 KMOD_SHIFT

参见文档:pygame.key

编辑:示例

import pygame
import pygame.locals

pygame.init()

screen = pygame.display.set_mode((300,200))

running = True

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                running = False
            elif event.key == pygame.K_a and pygame.key.get_mods() & pygame.KMOD_SHIFT:
                print "pressed: SHIFT + A"

pygame.quit()

顺便说一句:你可以使用 KMOD_LSHIFT或 KMOD_RSHIFT仅测试左移或仅测试右移。

顺便说一句:示例如何使用 get_pressed()

• 你必须使用K_LSHIFT和 K_LSHIFT检查两个类次。
• 如果您按住 SHIFT+A，它会一次又一次地打印“按下:SHIFT + A” .

import pygame
import pygame.locals

pygame.init()

screen = pygame.display.set_mode((300,200))

running = True

while running:

    #
    # events
    #

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_ESCAPE:
                running = False

    #
    # others
    #

    all_keys = pygame.key.get_pressed()

    #print 'shift:', all_keys[pygame.K_LSHIFT], all_keys[pygame.K_RSHIFT]

    if all_keys[pygame.K_a] and (all_keys[pygame.K_LSHIFT] or all_keys[pygame.K_RSHIFT]):
        print "pressed: SHIFT + A"

pygame.quit()

顺便说一句: get_pressed()和 get_mods()仅在 pygame.event.get() 时提供实际信息以前用过。

如何识别A, CTRL+A, SHIFT+A , ALT+A, CTRL+SHIFT+A, CTRL +ALT+A, SHIFT+ALT+A, , CTRL+SHIFT+ALT+A

                running = False

            elif event.key == pygame.K_a:

                mods = pygame.key.get_mods()

                if mods & pygame.KMOD_CTRL and mods & pygame.KMOD_SHIFT and mods & pygame.KMOD_ALT:

                elif mods & pygame.KMOD_ALT:
                    print "pressed: ALT + A"
                else:
                    print "pressed: A"


pygame.quit()

顺便说一句:在我的电脑上，Right Alt 有问题，因为它用于 native 字符。它不适用于 KMOD_ALT和 KMOD_RALT .
