Question

我有个问题。我有一个屏幕，已经充满了文本和按钮，我想按下按钮，填充我的背景颜色。（我知道关于这个话题有上百个问题，但我无法理解）。这是代码的一部分，我有按钮。我以为当我按下按钮时，很容易做出一个改变颜色的功能，但是当我按下按钮时，它会改变颜色，只要我按住鼠标键。当我不按住时，它只会返回一个带有文本和按钮的屏幕。在

Answer 1

你必须重新组织代码。在

我用fill()、文本、按钮和update()创建{}。在

我使用带数字的变量display_subscene来决定显示哪个子序列。在

你可以用类来更好地组织它。在

现在主要的问题是使用mouse.get_pressed()的按钮，所以它总是在不同的子场景中的同一个位置按下按钮。我不得不把按钮移到不同的地方。在

您必须使用event.type == MOUSEBUTTONDOWN

---

编辑在每个循环中，我都使用event.type == MOUSEBUTTONDOWN来设置变量mouse_button，我在button()中使用这个变量（作为新参数），这样当我按住按钮时，它就不会一直单击。变量mouse_button必须在每个^{之前设置0。在

我为屏幕添加了半透明背景Pause-你可以按pgame_loop来查看它。在
