为什么我的 pygame 屏幕在等待用户输入时没有响应？

问题描述

我是 Python 编程的新手，正在尝试为课堂创建游戏。每次我运行程序时，在用户将输入放入表面屏幕之前，它都会无响应。我做错了什么？

    pygame.quit()

main()

解决方法

首先，您不需要同时使用 event.pump() 和 event.get()，只需像现在一样在循环中使用 event.get。此外，您通常不会在 while 循环内定义函数。他们将在循环之外并从循环内部调用。您还同时调用 event.pump 和 event.get 并通过“input”获取输入。

您还可以在 while 循环内调用 pygame.quit()。将其分解为一系列函数。

main() - this calls all the others
get_input()
draw_screen()
etc

还有数字游戏说：

num_game=font.render("I am thinking of a number between 1 and 25,can you guess it? "

然后要求：

player_num=(input(" What is your guess 1 to 10: "))

您不能在应用程序循环中使用 input。 input 等待输入。当系统等待输入时，应用程序循环将停止并且游戏将不会响应。使用 KEYDOWN 事件代替 input：

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

        if event.type == pygame.KEYDOWN:
            # [...]

要么实现一个文本框（见How to create a text input box with pygame?）
或在单独的线程中获取输入（参见 Why is my display not responding while waiting for input?）。
