如何在 Pygame 中按住“键"? [英] How to hold a 'key down' in Pygame?

问题描述

我使用 Pygame 1.9.6 和 Python 3.7.4.我想按住空格键，它会一遍又一遍地连续执行相同的操作.我知道如何使用 KEYDOWN 按下按钮.我看了一下问题:如何在 Pygame 中有效地持有密钥? 的答案，但无法理解一个答案:

I use Pygame 1.9.6 and Python 3.7.4. I want to hold down the space bar and it continuously does the same action over and over. I know how to have have the button get pressed with KEYDOWN. I looked at the question: How to efficiently hold a key in Pygame? for answers but can't understand the one answer:

while not done: 
    keys = key.get_pressed() 
    if keys[K_DOWN]: 
        print "DOWN" 
    for e in event.get(): 
        pass # proceed other events. 
            # always call event.get() or event.poll() in the main loop

我没有得到 key.get_pressed().它不是来自 Pygame.另外，我假设这是他们编写的函数，但是当我按住键"时，它不会显示我，它会继续运行该操作，而当键"被释放时，它会停止正在调用的操作.关于如何实际按住按钮或如何制作按钮的任何指示?

I don't get the key.get_pressed(). It's not from Pygame. Also, I'm assuming it's a function they wrote, but this doesn't show me on when I hold down a 'Key' it continues to run that action and when the 'Key' is released it stops the action being called. Any pointers on how to actually hold down a button or how to make one?

推荐答案

pygame.key.get_pressed() 是一个函数形式 pygame.key 模块.它返回一个布尔值列表，表示键盘上每个键的状态.

pygame.key.get_pressed() is a function form pygame.key module. It returns a list of boolean values representing the state of every key on the keyboard.

如果你想测试 SPACE 键是否被按下，你必须通过订阅获取 K_SPACE 的状态:

If you want to test if the SPACE key is pressed the you have to get the state of K_SPACE by subscription:

keys = pygame.key.get_pressed() 
if keys[pygame.K_SPACE]:
    # [...]
