python - 使用 Python 输入速度跟踪器

Question

我正在关注如何使用 pygame 制作打字速度计算器的本教程，并且每当我运行代码时，一切都会按原样呈现，但是当我尝试单击文本字段输入一些文本时，它只是冻结并且没有任何反应。我试图在线搜索或观看教程，但一切都是空的。

Game().run()

如何解决这个问题？

您从不处理 KEYDOWN 事件。因为 else if 语句缩进很远。

您应该更改以下内容。

class Game(object):
    ...
    def run(self):
        ...
        while(self.running):
            ...
            for event in pygame.event.get():
                if event.type == QUIT:
                    ...
                elif event.type == pygame.MOUSEBUTTONUP:
                    ...
                    elif event.type == pygame.KEYDOWN:
                        ...

对此：

class Game(object):
    ...
    def run(self):
        ...
        while(self.running):
            ...
            for event in pygame.event.get():
                if event.type == QUIT:
                    ...
                elif event.type == pygame.MOUSEBUTTONUP:
                    ...
                elif event.type == pygame.KEYDOWN:
                    ...
