tikz: pause between generations in a tree in beamer presentation

Question

I have been writing the following code for a tikz-tree:

\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}

I would like to have pause between generations: would you help me in doing so?

Thanks a lot :)

Copy the TikZ code...

Paste them under the original one... place... \action between them... and leave the last copy untouched... but in each copy inserted before... either start changing color to be invisible or if possible delete the codes corresponding to the generations...

\documentclass{beamer}
\usepackage{tikz}
\begin{document}    
\begin{frame}[label=CCS]
\frametitle{Motivations and Directions}
\framesubtitle{The Cache County Study (CCS)}

\begin{figure}
\centering

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

\action<1>{\node[fill=orange!30, rectangle]{0};}

\action<2>{\node[fill=orange!30, rectangle]{0}
child { node {A} }
child [missing]
    child { node[fill=orange!30, rectangle] {F: 3} 
    }
child [missing]
child { node {C: 167} }
child [missing]
child { node {D: 92}};
}

\action<3>{\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 [missing]
child { node {C: 167} }
child [missing]
child { node {D: 92}};
}

\action<4>{\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 [missing]
child { node {C: 167} }
child [missing]
child { node {D: 92}};
}

\action<5>{\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}

Does \pause really work in this situation? For me, it just generates errors. — samcarter_is_at_topanswers.xyz, Jun 12 '16 at 18:21
As quiet galactic backwaters go, it is pretty good - almost silent and definitely part of some galaxy or other, but a bit on the dry side. On the other hand, perhaps the lack of wateriness has its upside given that the place exists in intergalactic cyberspace. — cfr, Jun 12 '16 at 20:09
