我同意@samcarter 的观点,但既然你说你是新手,那么在你熟悉了最基本的东西之后,阅读 aobs-tikz 手册可能会更容易。你所需要的只是\pause
一些非常简单的图片。
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{positioning}
\tikzset{mybox/.style={draw,minimum width=1.5cm}}
\begin{document}
\begin{frame}[fragile]{Boxes popping up}
\begin{overlayarea}{\textwidth}{8cm}
\begin{tikzpicture}
\node[mybox](A){A};
\pause
\node[mybox,above right=of A](B){B};
\node[mybox,below right=of A](C){C};
\draw[-latex] (A.east)--(B.west);
\draw[-latex] (A.east)--(C.west);
\pause
\node[mybox,below right=of B](D){D};
\draw[-latex] (B.east)--(D.west);
\draw[-latex] (C.east)--(D.west);
\pause
\node[mybox,right=of D](E){E};
\draw[-latex] (D.east)--(E.west);
\end{tikzpicture}
\end{overlayarea}
\end{frame}
\end{document}
