Pygame Key Constants未定义

每当我尝试在游戏中添加键盘输入时，只要我按下键盘上的内容，就会显示K_SPACE或K_<ANYKEY>未定义。

我尝试使用其他密钥，但它并没有解决问题，而是让我K_<OTHERKEY>未定义。我正在开发Raspberry Pi。我该怎么做才能解决这个问题？

这是我的代码：

pixelSize = [pixelSizeX, pixelSizeY]

2 个答案:

答案 0 :(得分：3)

关键常量应以pygame为前缀。

e.g。

pygame.K_RETURN

您的导入声明已读

import pygame

所有这一切都是导入pygame作为模块，pygame的所有成员仍然必须由pygame.<member>限定才能访问。

如果你编写了像

这样的导入语句 
from pygame import K_RETURN, K_S, K_W, K_UP, K_DOWN

或

from pygame import *

然后你可以像在问题中那样使用关键常量。当您从pygame导入更多内容时，前者可能会变得单调乏味。后一版本被认为是不好的做法，因为它将未知数量的项目导入您的模块全局范围。

您还可以使用pygame.前缀，从而提高可读性，因为该值的来源是明确的。

答案 1 :(得分：3)

另一个答案是正确的，但我只是想给你一个解释，这样你就可以从这个错误中吸取教训，下次你会知道它是什么了！

import pygame

导入模块名称pygame但不输入pygame中定义的函数/类的名称。您需要使用模块名称，以便可以访问以下内容中的函数：

pygame.K_RETURN

基本上，你是解释器知道检查模块pygame的K_RETURN。
