Cryptocode/falign：行间距

我正在使用加密代码在文档中显示一些与加密相关的内容memoir，但我想减少默认间距，这个间距非常大（特别是在文档其余部分使用一半间距时）：

我设法使所有东西都变小，但仍然遇到一些问题，有时候间距太大（红色方块，有时甚至比原始图片还要大），有时候间距不够（绿色圆圈）：

有什么办法可以修复它吗？ 平均能量损失

的正文排版\gameInteract没有特别注意行距。您可以通过将其设置Spacing为 1.2 并将标签放在箭头上方来获得统一的距离。我还使用 缩小了它们的尺寸\scriptstyle。如果您不喜欢这种风格，请将其删除。

\\您可以使用可选参数向制表环境的相应换行符添加负空格来消除“红框” \\[<vertical space>]。

标题行和正文之间的间距由 控制 bodylinesep。我不确定您是否要增加或减少默认值（-3pt在示例中设置为 以显示效果）。

简化环境后，“绿圈”问题消失gameInteract。
