tikz：在投影仪演示中的树中的几代之间暂停

Question

我一直在为 tikz-tree 编写以下代码：

\documentclass{beamer}
\begin{document}    
\begin{frame}

\begin{figure}
\centering

\begin{tikzpicture} [nodes={draw, rectangle, fill=orange!30, sibling distance=10cm,minimum height=2em}, ->]

\node[fill=orange!30, rectangle]{0}
child { node {A} }
child [missing]
    child { node[fill=orange!30, rectangle] {F: 3} 
    child { node[fill=orange!30, rectangle] {G: 28} 
    {child {node{Z}}}
      child {node[fill=orange!30, rectangle] {L: 22}}
        child [missing]
      child {node {B: 296}}
    }}
child [missing]
child { node {C: 167} }
child [missing]
child { node {D: 92}};
\end{tikzpicture}

 \end{figure}
 \end{frame}
  \end{document}

我希望在几代人之间有一个停顿：你能帮助我这样做吗？

多谢 ：）

复制 TikZ 代码...

将它们粘贴到原来的下面...放置...\action它们之间...并保持最后的副本不变...但在之前插入的每个副本中...要么开始改变颜色以使其不可见，或者如果可能的话，删除与世代相对应的代码......

\documentclass{beamer}
\usepackage{tikz}
