Question

我如何在pygame中实现滚动文本？由于Text类是从Sprite派生的，我以为我能够以通常的方式将它包装成Sprite对象。相反，它只是从屏幕的左边缘消失，永远不会返回（我不能让它从每一侧反弹）。

我的目标是加强我在一些教育材料中所涵盖的内容。但是，滚动文本并不是其中之一（虽然看起来很酷）。

谢谢，

戴夫

代码（特定区块正在评论＆＃39;在屏幕底部添加滚动文字＆＃39;）：

# Displays sequences of sounds and/or colors which the user must repeat

在livewires中，我没有看到任何可以处理这一切的内容。您可以将livewires.Object与一些自定义代码一起使用。像livewires.game.Text那样构建你的表面然后移动它。或者甚至使它可以勾选并跟踪应该显示的文本部分以及blit该部分到对象表面。
