我有问题。我有一个已经充满文字和按钮的屏幕，我想按下按钮并用颜色填充我的背景。 （我知道关于这个主题有数百个问题，但我无法理解它们）。这是代码的一部分，我有按钮。当我按下按钮时，我认为制作一个改变颜色的功能会很容易，但是当我按下按钮时它会改变颜色，只要我按住鼠标按钮。当我没有按住时，它只返回带有文本和按钮的屏幕。

答案 0 :(得分：0)
您必须重新组织代码。
我使用"subscenes"，文字，按钮和fill()创建update()。
我使用带有数字的变量display_subscene来决定显示哪个子场景。
您可以使用类来更好地组织它。
现在主要问题是使用mouse.get_pressed()的按钮，因此它会在不同的子场景中按下相同位置的按钮。我不得不把按钮移到不同的地方。
您必须使用event.type == MOUSEBUTTONDOWN
编辑我使用event.type == MOUSEBUTTONDOWN来设置我在mouse_button中使用的变量button()（作为新参数），这样它就不会＃39} ;按住按下按钮的所有时间点击。变量mouse_button必须在每0之前设置for event。
我为屏幕Pause添加了半透明背景 - 您可以按p game_loop进行查看。
