setbeamerunco​​vered 问题/错误？

我正在尝试使用两列在 Beamer 中创建一个演示文稿，一列是 tikzpicture，另一列是列表。我希望在 tikzpicture 中发现节点，同时在列表列中显示相关文本说明。我可以使用\setbeameruncovered{transparent}但灰色显示下一个节点和要显示的文本。我希望下一个节点/文本不可见。如果我使用\setbeameruncovered{}或将其全部注释掉，我会得到 tikzpicture 逐渐出现但文本逐渐消失...

有人能指出我犯的简单错误吗？

下面的代码...只需注释掉\setbeameruncover{transparent}即可获得消失的文本。（我知道这不是最短的例子……！）

答案1

  1. 由于transparent一般不会提供不可见的物品，因此使用invisiblefor \setbeamercovered（顺便说一下，这是默认设置，因此您只需删除 for 行即可\setbeamercovered）。
  2. 使用括号括起参数\onslide（我在您的示例代码中对大多数\onslides 都这样做了，但不是全部（没有时间这样做））：

这是您修改后的代码：
