Pygame 个按钮未创建工作按钮
Pygame buttons not creating working buttons
我正在尝试在 pygame 中制作刽子手游戏，但在从事件创建按钮后（在我的情况下，在按下 enter 后）我无法让按钮工作，它们出现在屏幕上但是不工作（翻转或激活事件），请帮助！

if __name__ == '__main__': main()
button函数在event.key里面，所以只有当RETURN被按下，松开，再按下，再松开，等等
您应该使用方法 draw 和 handle_event 创建 class 以在不同位置的主循环中使用此方法。您可以在 event.key 中创建按钮，但您必须检查在不同位置按下的按钮。

简单的按钮。完整的工作示例。
当您按下按钮功能时 do_it 被调用并且背景颜色改变。
